MEMORANDUM **

Emery Soos, Sr., appeals pro se from the district court’s judgment dismissing his *334 action for lack of subject matter jurisdiction. We have jurisdiction under 28 U.S.C. § 1291. We affirm.

In his opening brief, Soos fails to challenge the district court’s decision dismissing his action for lack of subject matter jurisdiction and therefore he has waived such a challenge. See Smith v. Marsh, 194 F.3d 1045, 1052 (9th Cir. 1999) (“[O]n appeal, arguments not raised by a party in its opening brief are deemed waived.”); Greenwood v. FAA, 28 F.3d 971, 977 (9th Cir. 1994) (“We will not manufacture arguments for an appellant....”).

AFFIRMED.
