sides slightly costate. Femora robust, the anterior strongly, the 
posterior femora more finely toothed. 
Length 3-4 mm. 
Hah. 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. picea, 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. 286. 
Subquadrate-ovate, black; the antennae flavous ; head, thorax 
and legs fulvous ; elytra black, distinctly punctate-striate, an 
oblique stripe near the suture and the apex broadly fulvous. 
Head entirely impunctate ; the eyes surrounded by a narrow 
sulcus ; clypeus impunctate, 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 aud 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 bilid. 
Yar. a. Fulvous, a spot at the base and a stripe at the middle 
of the elytra black. 
Yar. h. Entirely fulvous without markings. 
Length 2-2| mm. 
Hah. Southern Bombay : Kanara ; Belgaum. 
Smaller and of more subquadrate shape than T. hifasciata 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.
