a blunt tube projecting straight down from the abdomen at about its 

 middle; pollen of abdomen gray, with large dots at bases of the 

 hairs and bristles, apices of second and third segments subshining 

 black; fourth segment wholly pollinose, the discal row of bristles 

 distorted into the shape of a narrow ellipse or almost into two 

 parallel longitudinal rows. The abdomen is not yellow at the sides 

 as in the male. Legs brownish black, the front femora yellowish 

 underneath on apical half, middle and hind femora without distinct 

 ciliation underneath. 



Wings of a lighter and more uniform brown. 



Length of male, 9.6 mm. ; of female, 7 mm.

Schiner gives only a brief note on a pair from Brazil. Brauer and 

 Bergenstamm give only the generic reference. 



The material received from Vienna under this name is as follows: 



1. A male labeled Tachina macrocera Wiedemann and also " Bra- 

 silia, Coll. Winthem," it also bears a recently added red "Type" 

 label. This, however, can not be Wiedemann's type, as it has an- 

 tennae of ordinary size, while Wiedemann says "Antennis maximis,'" 

 and " Mit sehr grossen Fiihlern." We have additional specimens of 

 this species, and I am describing it below as Gopecrypta orhitalis new 

 species. 



2. A male and female each labeled " macrocera det. B. B.," and 

 " Novara R. Brasilia." These are apparently the pair mentioned by 

 Schiner as tiiacrocera, since they differ in the antennae as he says. 

 The female belongs to Copecrypta nitens Wiedemann, mentioned be- 

 low, and the male I identify with Gopecrypta nitidifrons Van der 

 Wulp, on comparison with two female paratypes of that species from 

 Mexico donated to the United States National Museum by the au- 

 thorities of the British Museum. It has antennae of ordinary size 

 and differs from orbitaUs most obviously in not having orbital 

 bristles. 



None of the three specimens belongs to m-acrocera Wiedemann, 

 but a male sent along for identification and belonging to a related 

 species is, I am confident, the true macrocera, and very likely the type 

 specimen, as it dates from the same period. 



The species is here referred to the genus Guphocera, the genotype 

 of which {t^ficmmis Macquart of Europe) has rudimentary, minute 

 palpi and no ocellar bristles, while Truicrocera has no palpi and a 

 distinct pair of ©cellars. Townsend has proposed the genus Deo-
