411 Lt.-Col. Win a Sampson on 



and slightly punctured ; scutellum triangular, transverse, and 

 shiny black ; elytra the same breadth as the prothorax and 

 very little longer, sides slightly rounded and the breadth 

 decreasing somewhat to the bluntly rounded apex, longi- 

 tudinally very convex, punctate-striate, the interstices with 

 a single row of piliferous punctures almost to the declivity, 

 from thence to the apex having uniseriate, short, and sharp- 

 pointed tubercles, the apical margin slightly but acutely 

 elevated ; the anterior femora in some specimens are paler in 

 colour than the tibiae. 



This species seems allied to several already described from 

 the East Indies, but is probably nearest to X. fornicatus, 

 Eichh., from which it differs in having a more convex 

 surface, much more prominent tubercles, a difference in shape 

 of the prothorax, &c. 



Xyleborus improlnis, sp. n. 



Oblongus, subnitidus, nigro-brunneus, prothorace semigloboso, 

 gibbo, antice exasperato, postice aubtiliter punctato; elytris quam 

 prothorace fere duplo longioribus, striato-punctatis, interstitiis 

 subplanis, 2° biseriatim, cetera uniseriatim punctatis ; 2° in 

 summa declivitate parva spina una, 3° spinis parvis ornato. 



Long. 3 mm. 



Loc. Darjeeling (B. B. Osmastori). 



Front black, subconvex, just above the mouth are two 

 coarsely punctured depressions separated by a slight longi- 

 tudinal elevation, the posterior surface is finely reticulate ; 

 prothorax subglobose, anteriorly asperate, transversely gibbous, 

 posteriorly finely shagreened and sparsely granulate, with a 

 very small cluster of piliferous punctures at the centre of the 

 base. The scutellum black, transverse, and feebly punctate. 

 Elytra equal in breadth to the prothorax and about half as 

 long again, subparallel-sided, with the apex somewhat bluntly 

 rounded ; striate-punctate, the punctures being variolose in 

 character ; there is a double irregular row of punctures on 

 the second interstice up to the commencement of the declivity, 

 where there is a short sharp spine, the declivous portion 

 having a single row of minute punctures, each furnished with 

 a very long hair ; the third interstice has two or three small 

 spines on the declivity, which is depressed on each side of 

 the suture ; the striae are sinuous outwards towards the apex, 

 which is marginate. Somewhat similar to X. horridus, 

 Eichh., but most nearly allied to my species, X. niger, from 

 the Ruby Mines, Burma (Ann. & Mag. Nat. Hist. ser. 8, 

 vol. x., August 15)12, p. 217).
