120 INSECUTOR INSCITI^ MENSTRUUS 



the description of the latter was taken at Giialan, by W. P. 

 Cockerell, who has pubHshed a vividly interesting account of 

 her visits to that semidesert region (Can. Ent., XLIV, 277-81). 



Zygobothria Mik (B. B.) equals Schaumia R. D. (1863). 

 Genotypes apparently strictly congeneric. 



Atropharista Townsend, 1892, Trans. Am. Ent. Soc, XIX, 

 92. In addition to the antennal and macrochsetal characters, 

 this form lacks the "short erect abundant black pile" of ab- 

 domen and thinner pile of mesoscutum described by Williston 

 for male of Melanophrys (Trans. Am. Ent. Soc, XIII, 306). 



Dejeania plumitarsis Wulp, 1888, Biol. C.-A. Dipt., II, 10, 

 pi. 1, fT. 5a, 5b equals Dejeania corpulEnta Wd., Mcq., Sch., 

 B. B. (non Wulp) equals Echinotachina Townsend, 1913, 

 Psyche, XX, 104-5. The revised characters are as follows: 

 Third antennal' joint much enlarged apically (R. D. calls at- 

 tention to this character as being of generic value — Posth., 

 I, 655) ; female front tarsi widened; male front tarsi with row 

 of long black hairs on inside of joints 2 to 4; anal segment of 

 male with long black bristly hairs extending beyond the rufous 

 pile and black spines. 



Dejeania corpidenta Wulp (non Wied. et al.), 1888, Biol. 

 C.-A. Dipt., II, 9-10, pi. 1, f. 4 equals Dejeania vExatrix O.-S. 

 equals TrichodEJEania Townsend, 1913, Psyche, XX, 104-5. 

 Characters are : Third antennal joint not enlarged at tip, convex 

 on upper edge ; female front tarsi not widened ; male front 

 tarsi without inside row of long hairs, and anal segment with- 

 out the longer bristles. 



Chcetotachina B. B., 1889, Muse. Schiz., I, 98 equals Eribea 

 R. D. (1863). Has same genotype. 



Neothelaira dexina Townsend, 1912, Jour. N. Y. Ent. Soc, 

 XX, 109-10 equals Masicera auriFrons Coq., 1897, Rev. Tach. 

 115. External adult characters will appear in forthcoming 

 paper. 



Coquillettina Walton, 1915, Proc Ent. Soc. Wash., XVII, 

 104, stands solely on the character of the obliterated apical 

 crossvein, and evidently equals Euacemyia Townsend, 1912, 

 Proc. Ent. Soc. Wash., XIV, 163-4. It is doubtful if the 

 obliteration of fourth vein carries specific value (vide Schiso-
