4.8 [February, 



7. — Bianous punciiventris, n. sp. 



Extremely like D. ct/anog aster, nigro-cyaneoua above, cyaneous beneath ; 

 the upper surface more shining, the puncturing a little more diffuse, that of 

 the prothorax much coarser and not so close, tlie ridge behind the oblique 

 grooves on the latter less prominent ; the elytra veith a broad transverse 

 depression behind the two longitudinal ones, the former bordered by a curved 

 sinuous line of cinereous pubescence; the ventral surface closely, uniformly 

 punctate. 



J . Fifth ventral segment depressed down the middle from a little b^low 

 the base and triangularly emarginate at the apex, the sixth with a deeper 

 triangular emargiuation. 



Length 6^-7^ mm. {6 2-) 



Hal. India, W. Almora (H". G. C: iv.1918). 



Five examples. Separable from both D. cyanogaster and D. in- 

 aequalis by the uniformly punctured ventral surface, there being no 

 trace of an impunctate glabrous median area in D. punctiventris. The 

 head and elytra are a little broader, the prothorax is more rounded at 

 the sides anteriorly and less shining, the elytral depressions are shallower, 

 and the antennae distinctly shorter, than in D. inaequalis. 



8. — Dianous loligerus, n. sp. 



Aeneous or greenish-aeneous, the head, prothorax, abdomen, and under 

 surface sometimes with a faint bluish suffusion, the antennae and palpi blnck ; 

 shining, sparsely, finely pubescent (the prothorax excepted). Head broad, 

 densely, finely punctate, the intra-ocular grooves deep ; eyes not very large ; 

 antennae extremely long, about reaching the middle of the elytra. Prothorax 

 a little longer than broad, rounded at the sides, constricted before the base ; 

 densely, rather coarsely, irregularly punctate, the punctures obliquely or trans- 

 versely confluent; sulcate for a short distance at the middle of the disc, and 

 with an angular excavation on each side of this, and somewhat depressed at 

 the base. Elytra wider than the head, longer than broad, rounded at the sides 

 posteriorly ; depressed along the suture anteriorly, within the humeri, and 

 behind the middle ; densely, rather coarsely, rugosely punctate, the punctures 

 obliquely or sinuously confluent on the depressed area on the disc and trans- 

 versely so near the basal portion of the suture, the tumid space exterior to 

 this a little smoother than the adjacent surface. Abdomen densely, minutely, 

 the penultimate dorsal segment more coarsely, punctate ; ventral segments 1-3 

 with a bare, smooth space down the middle, 5 clothed with rather long 

 yellowish hairs at the apex ; anal brushes long. Fourth tarsal joint bilobed, 

 the lobes long and narrow. 



(J . Sixth ventral segment deeply, triangularly emarginate, the seventh 

 sharply dentate at each outer angle. Genital armature (fig. 4) : lateral lobes very 

 long, slender, widened towards the apex, ciliate within ; median lobe rapidly 

 narrowed, pointed at tip. 



Var, Cyaneous, the elytra brassy. 



Length 6^-7^ mm. ( J 2 •)
