Superfamily EVANIOIDEA 1115 



pallipes Cresson. N. B. w. to s. B. C, s. to n. Va., Mo., n. Idaho, and n.e. Wash.? Host: 



Xiphydria )nellipes Harris. In the U. S. Natl. Museum collection there are two females 

 from Metaline Falls, Wash, (a locality cited for pallipes in Townes' [1950] revision of the 

 Aulacidae) which are less melanistic than other pallipes specimens in the collection. 

 They bear Hopkins no. 21306, the card for which indicates that they were collected 

 while ovipositing in Pseudotsuga 7)ie7iziesii infested by Buprestis sp. P. menziesii is not 

 known to be a host for any Xiphydriidae.

Family GASTERUPTIIDAE 



This small family is nearly worldwide in distribution (unknown from Micronesia and Polyne- 

 sia). Crosskey (1962) recognized two subfamilies, the Hyptiogastrinae with five genera and the 

 Gasteruptiinae with one genus. Because Gasteruption includes the vast majority of Gasterup- 

 tiidae, there is little practical value in recognizing two subfamilies at this time. 



The accounts of the biologies of Gasteruptiidae given by Hoeppner (1904) and Malyshev (1968) 

 indicate that the larvae are predators or predator-inquilines in the nests of solitary bees and 

 sphecids which nest in wood. According to Hoeppner, the egg of Gasteniption assectator 

 (Linnaeus) is laid on a mature larva of the prey. After consuming the latter, the assectator larva 

 invades the cell of a second prey larva and consumes it also. The species discussed by Malyshev 

 deposited their eggs in proximity to an egg of a solitary bee, the exact positioning of eggs vary- 

 ing among species of gasteruptiids. Upon eclosion from the egg the gasteruptiid larva consumed 

 the egg of the bee. Sometimes the larva would then complete its development by feeding upon 

 the provisions in the same bee larval cell but often invaded one or more other cells where they 

 consumed both bee larvae and provisions.

Type-species: Iclnieitnion assectator Linnaeus. Desig. by Viereck, 1914 from 83 

 species included by Schletterer, 1885. The discussion by Crosskey (1962, p. 

 396-397) is based upon the erroneous assumption that species are included in a 

 genus described without included species by virtue of suppression of its name in 

 the synonymy of a genus having species.
