TRICLIOtfA. 473 



sides slightly costate. Femora robust, the anterior strongly, the 

 posterior femora more finely toothed. 



Length 3-4 mm. 



Hab. Bengal : Mandar. 



Closely allied to T. puncticeps, Duviv., the thorax much more 

 finely punctured. T. melanura, Lefev. is black above with 

 aeneous gloss, the clypeus is rugose and the interstices are flat. 

 The present insect varies much in size, the larger specimens 

 are probably females. T. picca, Jac., likewise from Bengal, is 

 also closely allied, but the thorax is broader, the sides are still 

 more rounded, and the puncturation of the same part is much 

 stronger.

 p. 280. 



Subquadrate-ovate, black ; the antennae flavous ; head, thorax 

 and legs fulvous ; elytra black, distinctly punctate-stpiate, an 

 oblique stripe near the suture and the apex broadly fulvous. 



Head entirely impunctate ; the eyes surrounded by a narrow 

 sulcus ; clypeus irnpunctate, fulvous like the rest of the surface, 

 separated from the face by a semicircular groove ; palpi and 

 antennae flavous, the latter rather long and slender, the third and 

 fourth joints equal, the terminal joint stained with piceous. Thorax 

 transverse, more than twice as broad as long, the sides rather 

 strongly rounded, narrowed in front and with a narrow margin, 

 the angles not produced but distinct, the anterior margin concave 

 behind the eyes, the surface fulvous, sparingly and finely punctured 

 on the disc, the sides finely longitudinally strigose. Scutellum 

 black, as broad as long. Elytra black, strongly punctate-striate, 

 convex, scarcely perceptibly depressed below the base, with an 

 oblique short band near the suture at the middle and the apex 

 broadly triangularly fulvous, this colour also extends upwards a 

 little way at the suture. Breast and abdomen black ; legs flavous 

 or fulvous ; the anterior femora dilated into a broad triangular 

 tooth, the other femora less strongly dentate ; claws bifid. 



Var. a. Fulvous, a spot at the base and a stripe at the middle 

 of the elytra black. 



Var. 6. Entirely fulvous without markings. 



Length 2-2 mm. 



Hab. Southern Bombay : Kauara ; Belgaum. 



Smaller arid of more subquadrate shape than T. bifasciata and 

 in addition to the system of coloration differs by the differently 

 sculptured thorax. The species is probably subject to a good deal 

 of variation, the specimens before me show already three 

 different variations : in one of the dark fulvous varieties, the 

 thorax is more closely punctured than in the others and the sides 

 are scarcely so strigose as in the type ; on the other hand, more 

 pale coloured and somewhat smaller specimens have a more 

 sparingly punctured thorax, but I believe that all these forms 

 represent only one species. Taken from February to July.
