Ajimura appeals from the district court’s order of November 6, 1978, denying his motion to dismiss the indictment or to reconsider earlier orders. We affirm.
I. Statement of the Case
Ajimura and a co-defendant were tried in July of 1977 for alleged willful attempts to evade the personal income tax laws in violation of 26 U.S.C. § 7201. During the course of the trial, the district court granted a mistrial.
On December 13, 1977, Ajimura and his co-defendant filed motions to bar retrial on the ground of double jeopardy. On March 16, 1978, the district court granted the motion as to appellant’s co-defendant but denied the motion as to appellant. United States v. Ajimura, 446 F.Supp. 1120 (D.Hawaii 1978).
On May 18, 1978, the Government filed a motion to set the case for retrial. On May 22, 1978, Ajimura filed a “motion for order amending order on motion to bar retrial,” requesting that the court’s March 16 order be certified as appealable under both Rule 5(a) of the Federal Rules of Appellate Procedure and 28 U.S.C. § 1292(b); The district court denied this motion on June 1, 1978.
Twenty-two weeks later, on November 3, 1978, Ajimura filed a motion to dismiss the indictment or in the alternative, a motion for reconsideration. The district court denied this motion on November 6, 1978. The next day Ajimura filed a notice of appeal with this court.
II. Subject Matter of the Instant Appeal
The district court indicated that it denied the November 3, 1978, motion primarily because the issue of the effect of the double jeopardy clause upon further prosecution of Ajimura had already been fully litigated.1 *512Although the notice of appeal was filed immediately after this order, the parties dispute the subject matter here on appeal. Ajimura contends that this court may appropriately address the district court’s denial of his double jeopardy claim on the merits. The Government, however, claims that the only issue upon appeal is whether res judicata barred further consideration of the double jeopardy claim by the district court.
We agree with the Government. Federal Rule of Appellate Procedure 4(b) specifies that an appeal by a criminal defendant must be taken within ten days of the entry of the judgment or order appealed from, unless the district court allows an additional thirty days. Thus, because the district court’s orders of March 16, 1978, and June 1, 1978, were entered more than ten days prior to the date of the notice of appeal, an appeal as to those two orders was not timely filed. We thus may not review those orders. See United States v. Stolarz, 547 F.2d 108, 109-10 (9th Cir. 1976), cert. denied, 434 U.S. 851, 98 S.Ct. 162, 54 L.Ed.2d 119 (1977); Smith v. United States, 425 F.2d 173, 174 (9th Cir. 1970).
It is true that many interlocutory orders cannot be appealed at the time of entry of the order. Instead they are reviewed as a part of an appeal from a later, appealable order. See United States v. Ryan, 402 U.S. 530, 533, 91 S.Ct. 1580, 29 L.Ed.2d 85 (1971); DiBella v. United States, 369 U.S. 121, 129, 82 S.Ct. 654, 7 L.Ed.2d 614 (1962); How field, Inc. v. United States, 409 F.2d 694, 696-97 (9th Cir. 1969); 18 U.S.C. § 3731; 28 U.S.C. § 1291.
An order denying a motion to bar retrial because of the double jeopardy clause is immediately appealable. In Abney v. United States, 431 U.S. 651, 97 S.Ct. 2034, 52 L.Ed.2d 651 (1977), decided over nine months before the district court’s order of March 16, 1978, the Supreme Court held that “pretrial orders rejecting claims of former jeopardy . . . constitute ‘final decisions’ and thus satisfy the jurisdictional prerequisites of § 1291.” Id. at 662, 97 S.Ct. at 2042. Thus, Ajimura could have appealed immediately from the district court’s order of March 16, 1978.
The time limits of Rule 4(b) prevent undue delay in the administration of justice and provide finality of orders and judgments, and thus must be carefully respected. See Stolarz, 547 F.2d at 109-10; Smith, 425 F.2d at 174; Advisory Committee Notes to Fed.R.App.P. 3, reprinted in 28 U.S.C.A.Fed.R.App.P. at 8; 9 Moore’s Federal Practice 11204.02[1] (1975); 16 C. Wright, A. Miller, E. Cooper, & E. Gressman, Federal Practice and Procedure § 3950 (1977). Had Ajimura complied with the *513ten-day time limit of Rule 4(b), his appeal from the March 16 order would have been taken in March of 1978. But he now urges us to address the substance of the March 16 order even though he did not file his notice of appeal for almost seven months. For us to consider the effect of the double jeopardy clause upon Ajimura’s retrial would thus eviscerate Rule 4(b); this we may not do. Whether we agree with the Seventh Circuit that denial of a double jeopardy claim may be reviewed on appeal from a judgment of conviction, see United States v. Gaertner, 583 F.2d 308 (7th Cir. 1978), is not now before us.
We conclude that upon this appeal we may review only the matters decided by the district court’s order of November 3, 1978.
III. Merits of Appeal
The district court indicated that it denied the motion of November 6, 1978, primarily because the matter had already been litigated.2 Ajimura does not claim that the district court erred in invoking the doctrine of res judicata under the circumstances of this case.
AFFIRMED.
