Senometopia militaris Walsh, Trans. Illinois State Agr. Soc. vol. 4, pp. 367-8, 

 1861. Illiuois ; reared from arni.v worm. 



Tachina picea Walker, Ins. Saund.. p. 293, 1852. Described from Colombia, 

 South America. The type, a male, is in the Britii^h Museum under the 

 name Chaetolygo. The following notes were taken from the type by Dr. 

 J. M. Aldrich in 1929 : "A large Winthenna male, not in best condition. 

 Antennae rather long, second joint wholly red; third brown on upper and 

 apical part. Above vibrissae the small bristles form something of a tuft. 

 Cheek one-eighth to one-tenth of eye height; palpi wholly yellow. Mid 

 tibia with one bristle; hind tibia ciliate. Sternopleural, 1, 1. Front tarsi 

 normal with claws and pulvilli not greatly enlarged. A very marked 

 sexual patch on third segment extending on fourth, with dense brown 

 brush on both. No median marginals on second segment ; third with row 

 of 12 ; fourth segment with numerous bristles on sides and apical half. 

 Calypters white. Third vein with two hairs. Ocellars small ; f rontals 

 to base of third antennal joint. Length 12.5 mm." It does not seem to be 

 identical with any other species discussed in this paper and appears to 

 be a distinct form of which I have seen no specimens. 



Tachina snhpicea Walkek, Ins. Saund., p. 297, 1852. Described from Brazil. 

 Type in the British Museum as Chaetolyga. The latter was also examined 

 by Dr. J. M. Aldrich, whose notes indicate that this form is a synonym of 

 the preceding species. 



Tachina elegans Bigot, in Sagra's Cuba, vol. 7, p. 810, 1857. Described from 

 Cuba ; the type, a female, is in the collection of J. E. Collin, Newmarket, 

 England. Dr. J. M. Aldrich has also examined this type and states that 

 " the tJT>e has no parafacial hairs, but is not in best condition. Fourth 

 abdominal segment red; last joint of front tarsi enlarged, nearly as long 

 as three preceding ones; sternopleurals two; hind tibiae densely ciliated; 

 raid tibiae with one bristle on outer front side near middle." This may 

 prove to be an earlier name for W inthcmia sexuaVn Curran, also described 

 (male only) from Cuba. 



Exorisfa infesta Williston, Illinois Eut. Rep., P- 65, 1885. Illinois; reared 

 from Laphygma frugrperd<i. 



Bworista plfttysamiae Townsend, Tr.nns. Amer. Ent. Soc. vol. 10, p. 288, 1892. 

 Described from a single female specimen reared from PTatymmia cecropia, 

 Ithaca, N. Y. According to the original description the type has only 

 one proclinate orbital bristle. In the material examined. I have not seen 

 any species in agreement with this character.
