striae on the head outwardly divergent from a medial longi- 

 tudinal line, the striae on the thorax and node of the pedicel 

 transverse ; abdomen smooth but dull, with piligerous points in the 

 smaller form or variety. Head, thorax and abdomen covered 

 with reddish scattered erect hairs ; pubescence yellow, seen only in 

 certain lights, fairly dense on the antennae and legs. 



$ . Legs much darker than in the > almost black, apex of 

 the abdomen testaceous brown ; the striae on the head divergent, 

 and on the pro- and mesonotum transverse as in the , on the 

 scutelluin they are longitudinal and on the median segment almost 

 effaced in some specimens. 



Length, $ 9-12; $ 11-13 mm. 



Sab. Spread throughout the Indo-Malayan region. 



This species varies a good deal in colour. I have seen specimens 

 from Singapore of a dark ferruginous red all over, and others from 

 South Teuasserim with the mandibles, legs and a portion of the 

 thorax only of that colour, the rest black.
