Stomoxys triangularis, mihi, sp. nov. 



cf . vSouth India. Long. 4^ mm. 



Head. Frons \, dark grey; face and antennae blackish grey ; 

 proboscis rather long ; palpi pale. 



Thorax. Rather deep yellowish grey. The four deep black 

 stripes narrow and separate on anterior margin, but united soon 

 afterwards into two broad stripes, which are continued thus to 

 posterior margin of dorsum. A black lateral stripe in front of wing. 

 Sides of thorax greyish anteriorly, blackish grey behind. vScu- 

 tellum ver}^ dark grey. Chaetotaxy apparently normal. 



Abdomen blackish grey, ist segment with posterior border 

 somewhat darkened, 2nd with a small triangular basal spot and 

 two large triangular spots occupying nearly all the segment, their 

 bases almost meeting in middle of segment, their apices directed 

 towards the posterior corners, 3rd segment with two similar irregu- 

 larly triangular spots placed more obliquely ; 4th segment with 

 two sub-triangular spots, their apices pointing hind wards. Belly 

 black. 



Legs black ; knees and tibise narrowly' at base reddish yellow.

Described from 2 cy cf in the Indian Museum collection taken 

 by Dr. Annandale in the Travancore State, South India (Madda- 

 thorai, i7-xi-o8, type, and Pallode, i6-xi-o8). 



N .B. — An obviously distinct and quite dark species, compared 

 with all others I know from the East. The abdominal markings are 

 distinct (when viewed from the side) in one of the specimens, but 

 the abdomen of the other is best described as blackish grey with 

 irregular blackish patches, though it is certainly of the same species.
