 mandibles ferruginous, dark at base ; flagellum long, crenu- 

 late, dark coffee-brown beneath.

 The much darker flagellum easily distinguishes it from 

 II. oxleyi. Head broad, eyes converging below, face with 

 much light hair; front minutely, very densely punctured, a 

 very small space in front of ocellus smooth and shining ; 

 mesothorax hairy, finely and densely punctured, but shining ; 

 area of metathorax semilunar, with fine irregular rugaa 

 extending over the whole surface; pleura shining ; tegulaj 

 rather large, smooth, pale reddish testaceous. Wings ample, 

 hyaline, nervures and stigma pale testaceous ; second s.m. 

 receiving first r. n. before the end ; third s.m. very much
