Subfamily Sarrothripinae 



This group is readily distinguished because it has neither cre- 

 master nor setae at the caudal end of the body, which is probably 

 due to the fact that its members are found in thick cocoons. The 

 dorsal surface of the body is very irregularly rugose with spinous 

 elevations, and there is a distinct row of spines along the caudal mar- 

 gin of the fifth abdominal segment extending from the rugose area on 

 the dorsum around nearly to the meson of the ventral surface. A 

 few spines are present in a similar position on the fourth abdominal 

 segment. The epicranial suture is always present, the labial palpi are 

 visible for their entire length, and only a small portion of the pro- 

 thoracic femur is exposed, or it may be entirely concealed. The 

 maxillae never reach the caudal margin of the wings, being about 

 seven eighths of their length, with the mesothoracic legs meeting 

 just caudad of them. The antennae always reach to the caudal mar- 

 gin of the wrings, while the mesothoracic legs do not, but the latter 

 are slightly longer than the maxillae. Both prothoracic and meso- 

 thoracic legs extend cephalad to the eye-piece, the mesothoracic legs 

 extending between the sculptured eye-piece and the antenna.
