Fabricius describes this species thus :—‘* Head, thorax and scutel- 
lum spotted with black: tegmina red: wings white. Of median size: 
head glaucous, with band at the base of the rostrum, and dot on the 
frons and vertex, dull black: thorax sub-cinereous with an anterior 
spot and two posterior spots common to the scutellum, black: scutellum 
concolorous, with the two common spots at the base and one towards the 
apex, dull black: tegmina ferruginous, a little lighter at the tips: body 
and wings black.” Signoret notes that the form of the anal appendage 
in the ? distinguishes this species. This is very large, deeply emargin- 
ate, covering a great part of the vulvar plates, more or less round on 
the sides and in shape like two approximated lobes. Walker describes 
his different species as varying from tawny to red-lead colour, testace- 
ous, luteous or orange : the tips of the tegmina are black, lurid or brown : 
posterior margins of abdominal segments and tip of abdomen, red, 
tawny, Iuteous or ferruginous, so that the form of the anal appendage in 
the ¢ isthe most steady character for distinguishing a species so variable 
in colour. Body long, 14-20 millims. 
The Indian Museum possesses specimens from Sumatra, Tenasserim, 
Arakan, Sikkim, and Assam.
