punctures appeal' to be less deep, and the surface less reticulate ; 

 before the apex, also, the punctures are less markedly elongate ; 

 the legs appear to be proportionally longer, but this is not very 

 evident ; the underside of the pronotuiu is sparsely punctured, 

 and the metasternum is more distinctly punctured than in the 

 type form. 



From 0. dohrni this variety may be known by having the 

 vertex a little less declivous, and by the more rectangular 

 shoulders of the elytra, which are over their whole surface more 

 finely and thickly and less deeply punctured, with the interstices 

 natter. 



The female differs from the male in having the labrum entirely 

 black, with the five central teeth sharper, and the third joint of 

 the antennae metallic black ; the vertex is more abruptly declivous; 

 the lateral apical angle of the elytra is sharper ; the trochanters 

 are dark, the whole tibiae being cyaneous, and the anterior and 

 intermediate tarsi are less dilated.

Madras : Coonoor, Nilgiri Hills, Dindigul. 



Type in coll. W. Horn. 



It has recently been taken by Mr. H. L. Andrewes on the 

 Nilgiri Hills with N. subclavata, and also in the Ouchterlony 

 Valley at a height of 3000-3500 feet. 



I am much indebted to Dr. Horn for kindly allowing me to see 

 a specimen both of the type and the variety ; they differ so much 

 in general appearance that it is not surprising that heat first 

 described them as separate species, but I think that he is right 

 in uniting them as varieties of one species.

Dark, strongly or slightly metallic, very variable both in colour 

 and sculpture. The species is closely allied to the preceding, 

 from which it appears chiefly to differ in having the pronotum 

 a little narrower at the base, and with its inflated portion 

 more ovate, more convex, and more dilated at the sides : more- 

 over the constriction before the base is deeper ; towards the 

 sides it is punctured and pilose : the elytra are less elongate, 

 only about half as broad again as the pronotum, with the 

 shoulders more quadrate and the apical and basal porticns more 

 obsoletely and scantily puuctured, and the central portion more 

 or less plicate ; the sternum is pilose and the apical portion 

 of the abdomen is concolorous with the other segments. 



The female is larger than the male, with the pronotum
