The prothorax is very convex in all parts, being strongly- 

 declivous at both sides and ends ; its most abrupt declivity is 

 behind but (except as that makes it so) it can hardly be called 

 tumid or tuberculate in front of the scutellum ; on a casual glance 

 the prothorax appears subcylindrical and parallel, but on more 

 careful inspection it is seen that the sides in their middle part are 

 gently rounded, thence considerably and roundly convergent at 

 the extreme front and also convergent close to the base, but 

 divergent again at the posterior angles which are considerably 

 produced and very sharp ; there is a Isevigate line down the 

 middle. The scutellum is of the form of a mitre and is placed on 

 the face of an abrupt declivity similar and opposite to the hind 

 declivity of the prothorax, there being on the latter two vague 

 impressions corresponding in position to the two tumidities which 

 are placed one on either side of the scutellum. The example 

 before me is evidently a little abraded, but it is clear that a fresh 

 specimen would be densely clothed with scale-like pilosity entirely 

 hiding the sculpture from view. On the head and prothorax this 

 pilosity is for the most part white or greyish-white, and on the 

 latter there are blackish-brown masses of pilosity almost confined 

 to the middle part of the segment (apparently along its whole 

 length) ; this dark pilosity is most conspicuous where it assumes 

 the form of an almost round and well limited spot on either side 

 of the middle line a little nearer to the front than to the base, — 

 behind which and about half way to the base is a similar but 

 smaller spot on either side of the middle line. My unique example 

 is glabrous down the middle line, and if this be the result of 

 abrasion it is probable that in a perfectly fresh specimen these 

 discoidal spots of the prothorax may be connected by continuous 

 pilosity with a strip of blackish pilosity running down the middle 

 line of which they would perhaps appear as lateral extensions 

 merely. On the elytra the most conspicuous marking appears to 

 be a space covered with black pilosity commencing on the lateral
