74 C. H. TYLER TOWNSEND. 



70. Tacliina sp. (s. str.) 



Colorado (Gillette). One specimen reared from a larva of Copto- 

 cycla. This is probably a new species of Tachiixt (in the narrow 

 sense). 



71. IVIiltograiiiiiia ciiierascens Towns. 



A specimen from southern Florida (R(^berts()n) agrees with the 

 types of this species in all respects, except that the face and cheeks 

 are a little less deeply golden or brassy pollinose, but have somewhat 

 more of a silvery shade. I will not venture to describe it as distinct. 



72. Miltogramnia trilineata v. d. W. 



Two male sjjecimens from southern Florida (Robertson), collected 

 February 16 and March 10, I refer to this species. They seem to 

 have the abdomen slightly more silvery than a specimen from southern 

 Illinois, but are otherwise identical. 



These two species both differ from Schiner's description of Mllto- 

 c/ramrna by not having the first abdominal segment shortened, and 

 by having the frontal bristles moderately strong. From his descrip- 

 tion of MacTonychia they differ in their smaller size, and the abdomen 

 being rather short conical. They agree with Enmaeronychia in hav- 

 ing one row of frontal bristles, and the orbital bristles present in both 

 sexes. The front is about one-fourth width of head (in both sexes?). 



73. Eumacronychia tlecens Towns. 



Seneca Ranch (north of 8pringerville), Arizona; one male, June 

 25. Also one female, Zuni River, Arizona, July 28. 



74. Eumacronycliia elita Towns., Trans. Am. Ent. Soc. xix, p. 100. 

 This species bears much superficial resemblance to the genus Gym- 



noprosopa Towns., more than does E. decern^. The following differ- 

 ences may be pointed out between it and that genus : Front fully 

 one-third width of head in male, a little more prominent; frontal 

 bristles weaker, more nearly equal ; two orbital bristles in male. 

 Facial depression about one-third width of face in male ; sides of 

 face rather wide ; cheeks wide, nearly one-half eye-height. Eyes 

 descending little over two-thirds as low as oral margin ; second an- 

 tennal joint rather elongate, third joint about twice as long as second ; 

 proboscis about as long as height of head, not stout ; scutellum with 

 two lateral pairs of macrochietse, but with apical decu.ssate pair 

 Avanting. Abdomen cylindro-conical, first segment not shortened ; 

 hypopygium exserted ; pulvilli of male elongate, claws short ; fourth 

 vein with a quite distinct wrinkle at bend, apical cross-vein only 

 slightly concave, apical cell narrowly open and terminating well 

 before tip of wing.
