Rather large, robust. Head, pronotum and scutel- 

 lum pale ochreous ; the former with a greyish spot, 

 within which, or at its base, a V-shaped line occurs 

 (but not always). The pronotum may be concolorous, 

 or else dotted with spots, or marked by disjointed lines. 

 Abdomen black, with rusty blotchings and a band above 

 the apex. Legs yellow, spotted, and streaked. Elytra 

 broad and round, with pale wide lines indicating the 

 seats of the nervures. The areas obscurely filled with 

 brown or with fuscous. Wings ample. 



The female is paler, with smaller punctuations. 

 Apex of pygofer yellow, cleft, and tufted. 



In many respects T. pleheja resembles the next 

 described species. Mr. Edwards says that this insect 

 "occurred in profusion, in July and August, amongst 

 long grasses, in a garden at Norwich, but I have 

 seen no other examples." I have myself only taken 

 a single specimen at Haslemere, which I have figured ; 

 but the figure of the female is from Mr. Douglas's 

 collection.
