mixtis, — setulisque brevibuspallidis raris ornatus; rostroquam 

 latiori duplo longioi i, supra 4- vel 5-carinato, arcuato ; anten- 

 narum funiculi articulis 3-7 vix latitudine crescentibus, 7° 

 vix transverse : prothorace quam longiori quarta parte 

 latiori, supra sequali, antice leviter tubulato, vix manifeste 

 punctulato, crasse confuse striato-i'ugnloso, lateribus leviter 

 arcuatis ; scutello distincto ; el}- tris prothorace quinta parte 

 latioribus, postice abrupte declivibus, striato-punctulatis, 

 puncturis sat magnis, striis leviter impressis, interstitiis vix 

 convexis, humeris baud prominulis ; mesosterno simplici 

 vix declivi ; prosterno inter coxas anticas quam antennarum

 The spots formed by white scales are, — 5 or 6 on either side of 

 the prothorax, of which 1 on either side near the front margin is 

 conspicuous and apparently invariable, — 1 on each shoulder, — a 

 number varying from 1 to 10 scattered about the external half of 

 each elytron, and generally a few along the suture on either side 

 (where these are reduced in quantity it is usually in the front half 

 that they are wanting). The prosternum between the anterior 

 coxaj is wide enough to afford room and to spare to receive the 

 club of one of the antennae. There is a well defined transverse 

 suture dividing the portion of the prosternum between the anterior 



C0X8B. 



I have seen six examples answering to the above description 

 and valuing only in the number of white spots and in one of them 

 being a little smaller and paler in colour than the rest ; a seventh 

 specimen (which I regard as a variety) has its ground colour 

 entirely pale brown, with the alternate interstices of the elytra 

 a little more convex than the others and the process of the basal 

 ventral segment unusually developed ; two specimens (which I 

 take to be the other sex, — probably female) have the upper surface 

 considerably suffused with white scales, — which obscure the spots
