SOME INDIAN COLEOPTERA (6). 



BY G. C. CHAMPION, F.Z.S. 



{Concluded from p. 184.) 



Dianous hifoveifrons, n. sp. 



(S . Slender, aeneous, the elytra aeneo-cupreous ■varieofate with frreenish , 

 the antennae, palpi, and legs black, the prothorax and the polished portions of 

 the under surface jjlabrous, the rest of the surface finely sericeo-pubescent ; 

 the prothorax shining and almost smooth, the head, elytra, and abdomen densely, 

 minutely punctured. Head large, obliquely narrowed behind the eyes and 

 deeply bifoveate between them ; antennae -ver}' long. Prothorax convex, 

 narrow, about as long as broad, constricted posteriorly ; deeply, obliquely 

 furrowed at the sides, the two furrows coalescent on the disc, the transverse 

 basal groove limited on each side anteriorly by an oblique-tumid space. Elytra 

 rather long, broad, uneven, abruptly, transversely impressed near the suture 

 before the middle and with a longitudinal groove within the humeri. Abdomen 

 narrow, gradually narrowing from the base ; the ventral segments with a 

 polished space extending down their entire length, similar to that on the 

 metasternum; sixth ventral segment triangularly emarginate at the apex. 

 Legs rather slender, moderately long ; fourth tarsal joint simple, penicillate. 



Length Q^ mm. 



ITab. Ranikhet Division of Kumaon {H. G. C). 



One male, sent last year unmounted with hundreds of specimens of 

 other species of the genus. A slender form allied to D. annandalei and 

 versicolor, differing from both of them in its much smaller size and less 

 robust build ; the obliquely narrowed head (the post-ocular portions being 

 rounded laterally in the insects mentioned), with very deep frontal foveae ; 

 and the narrower abdomen, which is very gradually narrowed from the 

 base to the apex. D. gracilipes has a similarly shaped head and abdomen, 

 but differs from the present insect in its much larger size, longer limbs, 

 more elongate elytra, etc. 



Dianous s^ihtorticosus, n. sp. 



Obscure greenish aeneous, the antennae, palpi, and legs black ; the head 

 closely, the prothorax densely, confluently, rugosely, punctate; the elytra with 

 dense, hue, vorticose sculpture, the rugae transverse along the suture below the 

 base, crowded and radiating behind the depression on the disc ; the abdomen 

 densely, minutely punctate, the ventral segmeuts 1-4, and the metasternum 

 also, with a smoother subglabrous space down the middle. Head rather 

 small, the frontal sulci somewhat shallow. Prothorax about as long as broad, 

 narrowed and constricted posteriorly, ebliquely impressed on each side of the 

 disc i;nd canaliculate to near the base, the disc also with a short, narrow, smooth 

 space in the centre, I'^lytra long, broad. Legs moderately long, not very 

 slender ; fourth tarsal joint narrowly, feebly bilobed. 

 Length oi-6 mm, ( $ .)
