cJ. Sixth ventral segment deeply triangularly emarginate. Genital 

 armature (tig. 9) : lateral lobes long, sinuate, compressed, curved inwards at 

 the apex, and set with long hairs along the inner edge at and before the tip; 

 median lobe dilated distally, the apex arcuato-emarginate in the centre, and 

 angulate externally and on each side of the emargination. 



Length 6-61 mm. (d?-) 



Hah. India, W. Almora {R. G. d viii.1917). 



Fifteen specimens. Smaller and less robust than D. cyanorjasfer, 

 the upper sui'face more shining, the puncturing o£ the head, prothorax, 

 and elytra coarser, distinctly vorticose in the depressed spaces on the 

 wir.g-cases, the ventral segments without glabrous impunctate space 

 and the 6 genital armature very different, the median lobe being dilated 

 (instead of pointed) at the apex. 



15, — Dianotis aereus, n. sp. 



Brassy above, the under surface and legs bluish, the antennae and palpi 

 black ; shining, very sparsely pubescent. Head a little wider than the pro- 

 thorax, closely punctate, the intra-ocular grooves deep ; eyes rather large > 

 antenTiae very long. Prothorax slightly broader than long, rounded at the 

 .sides anteriorly, densely, roughly punctate, shallowly sulcate down the middle 

 anteriorly, and with a deep oblique groove on each side of the disc. Elytra 

 much wider than the head, a little longer than broad ; depressed along the 

 suture anteriorly, within the humeri, and across the middle ; closely, coarsely 

 punctate, the punctures more or less confluent, and separated by oblique 

 radiating rugae on the depressed portion of the disc and by transverse rugae 

 along the basal half of the suture. Abdomen densely, minutely punctate ; 

 anal brushes long, composed of numerous hairs. Legs long, not very slender ; 

 fourth tarsal joint without lobes. 



c? . Sixth ventral segment triangularly emarginate. 



Length 4^ mm. 



Hah. India, W. Almora {H. G. C). 



One male. Separable from the other species, D. minor excepted, 

 by its small size, less developed head, comparatively short prothorax, 

 brass}'' upper surface, etc. 



16. — Dianous minor, n. sp. 



Brassy above, the under surface and legs blue or bluish, the antennae and 

 palpi black ; shining, sparsely, finely pubescent, the prothorax and elytra almost 

 bare. Head not very broad, considerably wider thr.n the prothorax, closely 

 punctate, the intra-ocular grooves deep ; eyes rather small ; antennae com- 

 paratively short. Prothorax barely as long as broad, rounded at the sides 

 anteriorly, narrowed behind; closely, rather coarsely, irregularly punctate,
