Fabricius describes this species thus : — " Head, thorax and scutcl- 

 lum S2)otted 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 

 Bpot 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, luteous or ferruginous, so that the form of the anal appendage in 

 the 2 is the 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.

Whitish with yellow veins : head triangularly rounded in front 

 •with a black spot between the ocelli and on both sides, above the antennal 

 margin, near the eyes : ocelli blackish and placed in a deep groove : 

 basal band on thorax produced subtriangularly in the middle and two 

 basal spots on the scutellum, black : pronotum very convex in front, 

 straight behind above the scutellum, anteriorly transversly furrowed : 

 tegmina fuscous or yellow- white with the streaks a little brown, costal 

 half, whitish hyaline : abdomen and feet yellowish white ; vertex im- 

 pressed on both sides. Allied to T. albida, Walker, from which it differs 

 in its smaller size, narrower head, anteriorly more or less obtusely roundly- 

 subangulated, in wanting the median black apical spot, in the thorax 

 being more narrowed forwards, posteriorly a little broader than the head, 

 and especially by the cavities on each side in front of the eyes in which 

 are inserted the ocelli (Sign., Stal) ? Body long, 5 : broad, If millims.
