914 COLEOPTERA 



sinuously narrowed behind, posterior angles rectangular, apex in- 

 curved, base emarginate ; moderately convex, with feebly-marked 

 aciculate impressions, dorsal groove not abbreviated, basal fossae 

 large and deep, lateral rims scarcely reflexed. Scutellum lineated 

 at base. Elytra oblong, broader than thorax, shoulders dentate, 

 widest in line with posterior femora, their sides curved, deeply 

 sinuated posteriorly; punctate-striate ; interstices slightly raised, 

 the third and fiftla tri-punctate, seventh with about six large 

 punctures. Legs stout, thighs swollen. Underside shining, pitchy- 

 black. 



In all the knowni Trichosterni the intermediate and, to a less 

 extent, the posterior tibiae are ciliated with outstanding spiniform 

 bristles, but in this species the latter are depressed and flexible. 

 The form most nearly resembles the female T. fitlton'i ; the thoracic 

 angles are not quite so prominent, the elytra are broader, more 

 rounded, and decidedly more sinuous posteriorly, their striae are 

 well marked, but the punctures are small. The body is more 

 brightly coloured, and the limbs are quite red.

1635. T. meritus, ^'-5. Oblong, moderately convex, shining, 

 coppery (red), black, tarsi piceous, tips of palpi rufescent. 



Head slightly rugose in front ; eyes prominent. Prothorax 

 moderately convex, quadrate, transverse, anterior angles rounded, 

 sides not much curved, narrowed but only slightly sinuated pos- 

 teriorly, hind angles rectangular, not projecting, lateral margins 

 slightly reflexed and thickened behind ; basal foveae large and deep, 

 median groove distinct, its surface nearly smooth. Scutellum unim- 

 pressed. Elytra oblong, humeral angles prominent, sides mode- 

 rately rounded, sinuated apically ; punctate-striate, the punctation 

 small but distinct ; interstices a little convex, the third with three, 

 the seventh with five or six large punctures. Legs normal. Under- 

 side pitchy-black, bearing some fine, irregular, linear impressions. 



Allied to T. waiJiorensis, but with a quite different thorax ; the 

 space between the basal fossse is depressed.
