$ . Similar to 9 ; antennae nearly as long as the body, 15-jointed, 

 a little more slender apically, the joints beyond the fourth subequal in 

 length, the fifth about three times as long as wide; third and fourth a 

 little shorter, subequal. 



Described from 10 2 5 and 2 S 3 from cow dung in the 

 vicinity of Capetown, April, 1915, or bred from the puparia 

 of Musca lusoria and Lasiopyrellia cyanea. (Bridwell. ) 



The Lasiopyrellia, like the Musca, breeds in cow dung 

 and emerges to pupate in the soil. They feed in colonies in 

 the more putrescent portions of the dung and scatter when 

 ready to emerge. The Bothrochacis enters the dung through 

 interstices and attacks the full-fed larvae ready to emerge 

 from the dung. 



Type and allotype is the South African Museum ; paratypes 

 in the collection of the Hav/aiian Board of Agriculture and 

 Forestry and in the authors' collection. 



From the description I was at first inclined to identify 

 this with Bothrochacis erythropoda Cameron (Alba)iy Museum 

 Records 1:164 S, 1904), also from the Cape, but the radius 

 of that species is said to have the second abscir^sa roundly 

 curved. 



In Keffer's tables (Gen. Ins. Cynipidae 1902), this species 

 would run to Lytosema,- but Cameron's genus seems to differ 

 from Kieffer's by the position of the cupule. 



This species does not appear to be able to parasitize any 

 great percentage of the larvae of its hosts, since its movements 

 are slow and uncertain.
