from them all by the characters cited in the tabulation. The 

 apex of its elytral suture might, perhaps, be thought capable 

 of confusion with that part of H. elongatus as having a pencil 

 of bristles, but in this species similar bristles are closely placed 

 along the whole apex of the elytra, and in elongatus are con- 

 fined to the apex of the suture. The sculpture of its dorsal 

 surface is very widely different from the corresponding sculp- 

 ture in elongatus. The trilobed outline of the head is well 

 developed and is divided, the middle lobe scarcely two-thirds 

 of a lateral lobe in size. The outline of the erect face of the 

 labrum (viewed from in front) is that of a segment of a circle 

 (the normal condition in species whose head shows a trilobed 

 outline) .

H. xanthotrichus , sp. nov. Minus elongatus, postice minus 

 dilatatus ; minus nitidus : obscure ferrugineus ; supra 

 pilis adpressis brevibus sat dense vestitus, pronoto antice 

 pilis elongatis erectis flavis fimbriate ; clypeo crebre sub- 

 tilius ruguloso, antice late leviter emarginato ; labro 

 clypei planum superanti, antice haud perpendiculari ; 

 capite antice (a tergo oblique viso) tripliciter convexo 

 (parte mediana quam laterales sat angustiori) ; fronte 

 crebre subtilius leviter punctulata; hac clypeoque ut 

 plana minus disparia visis ; antennis 9-articulatis ; pro- 

 thorace quam longiori ut 12 ad 7 latiori, antice modice 

 angustato, supra confer tim subtiliter sat leviter punctu-

 lateribus (superne visis) leviter arcuatis, angulis anticis 

 sat acutis sat productis posticis (superne visis) 

 rotundato-obtusis, basi sat fortiter bisinuata, mar- 

 gine basali ad latera summa paullo magis

 latis, confertissime subtilissime leviter punctulatis (trans 

 elytron puncturis circiter 60) ; pygidio crebre subtiliter 

 punctulato ; coxis posticis quam metasternum hand

The form of the labrum (not turned up perpendicularly 

 in its apical part, but having its whole direction forward and 

 upward) distinguishes this species readily from the others of 

 its aggregate (C in A A, B). The trilobed outline of the head 

 is well developed and is divided, the middle lobe a little more- 

 than half of a lateral lobe in size. H. xanthotrichus is near-
