230 On new Species of Indian Ciivculionidse, 



differences in coloui- (the elytra being obscure red witli large 

 black patches), the latter differs in having all thetibi£e denti- 

 culate internally ; on the elytra the supra-humeral tubercle 

 is hardly percej)tible, and the otiier two are blunter, the third 

 being placed well behind the middle, while in front of it is a 

 broad oblique impression in which the sulci are obliterated; 

 the sulci elsewhere are distinctly deeper and posteriorly 

 almost catenulate rather than punctate, while the intervals 

 are evidently carinate ; further, tiie apices of the elytra are 

 much narrower, being separately rounded and not truncate. 



I have much pleasure in dedicating this species to my 

 friend Prof. H. Maxwell Lefroy, who has done such excellent 

 work in the position of Imperial Entomologist to tiie Govern- 

 ment of India, from which he has just retired, 



CossoyiN^. 



Cossonus bijiodosufij sp. n. 



Elongatus, modice convexus, omnino ater, nitidus, antcnnis tarsis- 

 que piceis. Rostrum antice non dilatatum, subparallelum, ad 

 basin Jeviter angustatum, supra obsoletissime punctatum. Pro- 

 thorax in medio triaugulariter levissime impressus, ira])ressione 

 (fere ad apicera extensa) efc lateribus rude punctatis, area longitu- 

 dinali angusta in dorso utrinque impunctata. Elytra oblouga, 

 modice convexa, striis profundis puuctis maguis obsitis ; inter- 

 stitiis 2, 3, 7, 9 postice conjunctis et costam latam obliquam 

 elevatam forraantibus ; interstitiis dorsalibus angustis subplania 

 impunctatis. 



Shiny black, with the antennre and tarsi piceous. Head 

 impunctate on the vertex, the forehead with a large deep 

 central fovea and a few scattered punctures. Roslrum sub- 

 parallel-sided anteriorly and slightly narrowed towards the 

 base, the lower edge of the scrobe projecting slightly when 

 viewed from above; the upper surface almost impunctate, 

 except for a few coarse punctures at the extreme base, the 

 sides also punctured towards thje base. Prothorax broadest 

 near the base, roundly narrowed in front, and with a distinct 

 apical constriction, the base strongly bisinnate ; the dorsum 

 with a very shallow median triangular impression (almost 

 reaching the apex),vvhicii is very coarsely punctured and has 

 an irregular central carina ; on each side of this is a rather 

 narrow, obliquely longitudinal, impunctate area, the entire 

 lateral area beyond this being very coarsely and closely 

 punctured. Elytra oblong, moderately convex, the sides 

 parallel from the shoulders to well beyond the middle, thence 

 slightly narrowed and very broadly rounded at the apex ;
