Crest of pronotum considerably elevated, the anterior two lobes 

 merged into one, which is elevated abruptly in front and slopes grad- 

 ually away behind ; the two succeeding higher, angular, parted and 

 deeply cleft; the posterior portion of the crest at once doi)ressed, of 

 nearly uniform height, bluntly serrulate. Tegmina violaceous, varied 

 with pale and yellow spots; wings brick red, with a broad black 

 margin along the whole posterior border, and black quadrate and 

 rounded spots interspersed over the whole wing, forming near the 

 anal border narrow, wavy or irregular, transverse, parallel and ap- 

 proximate bands of black. Hind femora spotted externally with 

 white. After Perty. 



An alcoholic specimen (9, no locality) in the Society's Museum 

 has a pronotal crest, the anterior portion of which agrees altogether 

 in form with that of T. rex, but posteriorly the serrulations are blunt; 

 the posterior surface of the pronotum is furnished with irregular 

 tubercles, which are independent, distant, rounded, — not confluent, 

 approximate, linear, as in T. rex ; the crest and posterior border of 

 the pronotum are not edged with black as in the latter ; and the 

 spines of the hind tibiae are only tipped with black, instead of being 

 wholly black; the pale bands on the apical half of the tegmina of 

 T. Latreillei are broad and diagonally disposed, not narrow and 

 transverse, as in T. rex.
