SARCOPHAGA AND ALLIES 265 



side two distinct concavities, side by side, which ap- 

 pear to be very characteristic of this species. Middle 

 femur without comb. 



Length 6.5-7.5 mm. 



At the place of original description I have listed 

 several hundred specimens of this species examined 

 at that time. They were largely reared from grass- 

 hopjDers in various parts of the west. Since the pub- 

 lication of that article I have seen four females in 

 the University of Kansas, reared by H. B. Hunger- 

 ford at Kinsley, Kans., from adults of Plectrodcra 

 scalator, the large Cerambycid borer in cottonwood. 

 Mr. Hungerford states that 90 per cent, of the beetles 

 were parasitized. I have also received for identifica- 

 tion two males and a female reared by Prof. H. F. 

 Wickham from Asida sp. at La Junta, CoL . (Web- 

 ster No. 15505). 



No specimens have been seen from localities east 

 of Central Kansas.
