H. camyestris, sp. nov. Modice elongatus, postice sat dil&- 

 tatus ; sat nitidus ; ferrugineus ; supra pilis sat brevibus 

 adpressis minus sparsim vestitus; clypeo crebre ruguloso, 

 antice late leviter emarginato : labro clypei planum 

 superanti ; capite antice (a tergo oblique viso) tripliciter 

 convexo (parte mediana quam laterales sat angustiori) : 

 fronte crebre rugulose punctulata; hac clypeoque ut 

 plana sat disparia visis ; an tennis 8 - articulatis, 

 articulo 3° quam 2 US sublongiori ; prothorace quam 

 longiori ut 24 ad 13 latiori, antice minus angus- 

 tato, supra minus crebre sat for titer punctulato 

 (puncturis cireiter 16 in segmenti longitudine) , 

 lateribus (superne visis) leviter arcuatis, angulis anticis 

 sat acutis minus productis posticis (superne visis) sub-

 magis elevato ; elytris subfortiter sat crebre granulatim

 crebre subtilius punctulato ; coxis posticis quam meta-

 This species bears a general resemblance to TI . granu- 

 latus, Blackb. It is, however, easily distinguishable from 

 that species by its notably shorter hind coxae, its pronotum 

 notably less narrowed in front, punctures of dorsal surface 

 evidently larger and less close. The trilobed outline of its 

 head is well defined and divided, the middle lobe about two- 

 thirds of a lateral lobe. The labrum presents the very un- 

 usual character of the upper (arched) outline of the erect- 

 front face, as viewed from in front, being finely margined.

Group VII. 



Since this Group and the next both contain numerous 

 species which are assigned to either Group, according as their 

 hind claws are bifid or appendiculate, and as there are un- 

 doubtedly degrees of bifidity and appendiculation, some 

 species being either strongly or feebly bifid or appendiculate, 

 it is, of course, obvious that in dealing with these Groups very 

 particular attention must be paid to the claws. I do not 

 think that there are any species in either Group whose claw- 

 structure would be likely on careful examination to be mis- 

 taken for that of the other Group. Nevertheless, it is possible 

 that an observer whose eye was not trained by lengthy study 

 of these insects might feel some hesitation in confidently
