Another species closely allied to the preceding two and to 

 gigantea, Burm. ; average specimens are of larger size however. 

 The prothorax (which is barely twice as wide as long) is more 

 strongly and closely punctured than in any of those three species, 

 while the flabellum of the antennae is different in the male beine: 

 six-jointed, and the female is equally distinct by the production 

 in a strong tooth-like process of the apical joint of the antennal 

 stipes.

COLPOCHILA DUBIA, Sp.nOV. 



Ovata ; sat opaca ; testacea vix iridescens ; capite prothorace 



scutello pedibusque rufescentibus ; pectore valde hirsute, 



abdomine setoso ; capite confertim rugulose confluenter 



nee crasse, prothorace elytrisque (his geminato-striatis) sub- 



fortiter minus sparsim, pygidio sparsissime sat subtiliter, 



punctulatis ; antennis 9-articulatis ; elytris apice suturali 



nullo modo producto ; tarsorum posticorum articulo 2° 1° 



sat longiori. 



Feminae antennarum flabello stipitis dimidio vix longiori, 5- 



articulato, articulo 2° quam 3"^ paullo (1"* quam ille multo) 



breviori, stipitis articulo ultimo intus obtuse vix dentato ; 



pygidio antice carinato. [Long. 11, lat. 6 lines. 



This species is extremely close to C. laminata, the only difference 



that I can specify of a non-sexual character being that the apex 



of the suture of the elytra is not produced in a short tooth-like
