near the base, the hairs three to four times as long as the joint bearing 

 them; basal joint of club with a half-whorl of similar long hairs above 

 near rniddle of joint and another half-whorl beneath and a little more 

 basad; abdomen not longer than the head and thorax, narrower than 

 the thorax and not pointed at apex. Antennae entirely pale testaceous; 

 abdomen with a large pale, nearly white spot at base above. Other 

 characters as in the female. 



Type locality, Tempe, Arizona. Type, Cat. No. 22300, 

 U. S. Nat. Mus. 



Three specimens, one female and two males, reared by Mr. 

 Wildermuth from galls of the alfalfa gall midge, Asphondylia 

 websteri Felt, under Webster No. 7268, Tempe No. 2264. Also 

 two females and two males reared by E. G. Smyth from the 

 same source. Antenna of female paratype and male allotype 

 on a slide. 



The host relations of this species are unknown to the writer. 

 It may be either a primary or secondary parasite of Asphondylia 

 or it may possibly have been parasitic upon Bruchophagus 

 fmiebris, specimens of which w'ere reared from the same lot of 

 galls. 



Tetrastichus bruchophagi Gahan. 



Specimens of this species were received from Mr. Wildermuth 

 under Tempe No. 2264, having been reared together with several 

 other species of Hymenoptera, including Bruchophagus funebris, 

 from galls of Asphondylia websteri Felt, collected in the field 

 and placed in vials for rearing parasites. The species is known 

 to be a primary parasite of Bruchophagus funebris and may 

 have been present in the Asphondylia gall in this role. On the 

 other hand, it is not unlikely that this species, like Trimero- 

 micrus maculatiis, may have developed as a secondary parasite 

 of Asphondylia using some one of the primary parasites of the 

 Cecidomyid as host. 



Paragaleospomyia gallicola, new species. 



It is very close to P. eja Girault, but differs in having the abdomen 

 more slender, and the hind tibias black only on the apical half. 



Female. Length 2 mm. Head, viewed from in front, slightly 



broader than long, the ventral margin nearly straight, cheeks slightly 



.convex in profile; antennal depression deep and broad with a shallow 



subquadrate extension below the base of antennae; ocelli in an obtuse 



triangle, the postocellar line about twice the ocellocular; face and cheeks
