/ 



Six specimens, the d" from Assam differenth' coloured, but agreeing 

 in other respects with those from Almora. Separable from D. andrewesi 

 by the strongly bilobed fourth tarsal joint, the still longer antennae, the 

 slightly smaller eyes, the rather coarser, less densely punctured pro- 

 thorax, the more uneven, less rugose elj'tra, the peculiarly scul25tured 

 ventral surface, and the pronounced 6 - characters. The Assam example 

 was sent me some years ago by my second son, who is also on Government 

 service in India. 



9. — DianoHS distigma, n. sp. 



Erassy-black above, steel-blue beneath, the elytra each with a very small, 

 rounded, dull, luteous spot, the antennae and palpi black ; shining, sparsely, 

 finely pubescent. Head much wider than the prothorax, closely punctate, the 

 intra-ocular grooves deep ; eyes large ; antennae long. Prothorax narrow, 

 rounded at the sides, constricted posteriorly ; densely, rather coart-ely, 

 irregularly punctate, sulcate do\^^l the middle towards the base, and with a 

 deep oblique excavation on each side of this, and also obliquely grooved 

 laterally in front of the basal margin. Elytra wider than the bead, a little 

 longer than broad, rounded at the sides posteriorly ; depressed along the suture 

 anteriorly, within the humeri, and behind the middle ; coarsely, closely punc- 

 tate, the punctures more or less confluent on the depressed portions of the 

 surface, and separated by oblique or sinuous rugae. Abdomen closely, 

 minutely punctate; ventral segments without dehnite impunctate median 

 area, 5 with some yellowish hairs at the apex ; anal brushes long. Legs not 

 very slender ; tarsi moderately elongate, somewhat thickened, the fourth joint 

 narrowly, feebly bilobed. 



S. Sixth ventral segment triangularly emargiuate. Genital armature 

 (tig. 5) : lateral lobes long, slender, almost straight, set with a few long, scat- 

 tered, projecting hairs on their inner edge ; median lobe sharply acuminate, 

 curved downward at the tip, the produced apical portion ciliate laterally. 



Length 5^ -6J mm. ( J ? .) 



Rah. India, W. Almora {R. G. C. : vi.l918). 



Seventeen specimens. This insect has the prothorax and elytra 

 sculptured much as in D. cameroni, differing from it in the less elongate 

 legs, the relatively shorter and stouter tarsi, the spotted elytra, etc. 

 The lobes of the fourth tarsal joint are shorter than in D. lohigerus 

 and a little broader than in D. cameroni. The present species 

 must be nearly related to D. verticosus Eppelsheim (1895), based on a 

 single example from Pegu, Burma, which is said to be coloured like 

 D. coerulescens Gyll., except that the shining. reddish spot on the elytra 

 is smaller and rounded.
