AMERICAN DIPTERA. 73 



66. Ciieplialia sp. 



Mesilla Valley of the Rio Grande, New Mexico. A characteristic 

 species of this genus is numerous in individuals about Las Cruces. 



67. Triclioplioi-H s]). 



Six specimens from southern Illinois i Robertson) I refer to this 

 genus. Mr. v. d. Wulp remarks on the doubtful distinctions between 

 this genus and Cuphocera ( Biol. Cent.-Amer., Dipt, iii, 85-36). The 

 two genera seem well marked. Cuphocera differs by its more elon- 

 gate abdomen and general narrower form, and should include C. 

 rufimuda v. d. W., which has an elongate abdomen. The present 

 species of Trichophom has a short, stouter abdomen, and general 

 much stouter form. It differs from Echinomyia only in the entire 

 absence of palpi, the third autennal joint being about as long as the 

 second, and the frontal bristles descending in a double row below 

 near the eye margin the so-called genal bristles ). The second and 

 third abdominal segments have only marginal macroeha?tiB. 



The character of the comparative length of the second and third 

 antennal joints does not seem to be rightly understood in the three 

 genera TrlcJiophora, Cuphocera and Echmomyia. The last has the 

 third joint shorter than the second. Cuphocera, according to the 

 type species, should have the same characteristic, but specimens which 

 I identify as C. macrocera Wd. and C. ruficauda v. d. W. have the 

 third joint fully as long as the second, or a little longer. These two 

 species, moreover, agree in their general elongate form, very notice- 

 able in the elongate abdomen, and thus would be readily separated 

 from the shorter, stouter species of Trichophora. The sj)ecies of 

 Trichophora above referred to may be distinguished at once from T. 

 nigra Mcq. by having two bristles on the sides of face near lower 

 margin i>i' eyes, instead of one as in that species ; and from T. analis 

 Sch. by the anal segment being wholly rufous, and the other segments 

 blackish, the sides of the anal segment in T. analis being broadly 

 black and the rufous extending on sides of second and third segments. 



68. Taoliina clisioeanipie Towns. 



Colorado (Gillette) ; one specimen bred from Danais archippu><. 

 The front is less golden than in the type from Maine. Sides of ab- 

 domen more distinctly red ; scutellum more generally rufous. Another 

 specimen, which I refer here with some doubt, Avas bred by Prof. 

 Gillette from Clmocampa califoruica. 



69. Tachina s]). 



Colorado (Gillette). A species with a P/<(ijia-\ike facies. One 

 specimen bred from Plusia brasdcai.
