humeral bristles. The two smaller ones are in but one specimen 
large enough to be distinguished from the other hairs or micro- 
chete. This variation of the posthumerals is common in Sav- 
cophage. 
Abdomen—The macrochete of the abdomen are marginal only. 
Each segment has a complete row. On the first and second seg- 
ments they are all of insignificant size except two or three at the 
lateral border. On the third segment all are of good size and they 
number twelve to fourteen. On the fourth segment all are of good 
size ond they number fourteen to sixteen. 
The bristles of the legs are arranged as is usual in Sarcophage 
D D i S 
I can make out nothing worthy of especial notice here. 
Wing—First longitudinal veia not spinose. Third vein not 
spinose for two-thirds to three-quarters of the distance to the small 
cross vein. Elbow of fourth almost exactly rectangular and pro- 
vided with an apparent appendix which, however, is not a stump 
of a vein but a slight fold or wrinkle of the wing. Hind cross vein 
sinuous, longer than, but hardly twice as long as, that segment of 
the fourth vein between it and the elbow. Hund cross vein and 
apical cross vein almost exactly parallel. 
This species belongs to Brauer’s subgenus 7ephrompia of Sar- 
cophaga (sens. lat.). In this subgenus the vibrissal angles are dis- 
tinctly above the mouth edge and, projecting somewhat mesad, 
distinctly narrow the clypeus. The abdomen does not have the 
changeable spots, macule spurie, of Savcophaga but is either uni- 
colorous or marked with fixed spotsor lines. The European species 
of this group are 7. grisca Meig., 7. déneata Fall., 7. affinis Fall., 
and Z. vésoleta Fall. As far as I am aware hwnteri is the first 
Tephromyia to be observed outside of Europe. Through the kind- 
mess of Herr Paul Stein of Genthin, Germany I have now in my 
possession specimens of grisea, affinis and obsoleta. From these 
specimens and the accessible descriptions of /meafa I am able to 
construct the following table for separating the species of this 
group, 
A—Abdomen unicolorous, squamule yellow, wings strongly yel- 
low at base—vevzsea Meig. 
AA—Abdomen with distinct black markings, squamule not yel- 
low, wings not strongly yellow at base. B. 
B—Palpi black. C. 
C—Each abdominal segment with a black dorsal line and on 
-each side withe a narrow, oblique, black spot, These spots often
