mark something more than a mere variety, viz., — the puncturation 

 of the prothorax finer and less close and the pygidium altogether 

 ISevigate. 



I have not seen a male that I can attribute to this species. 



S. Australia. 



COLPOCHILA GRACILIS, Sp.nOV. 



Elongato-ovata ; sat nitida ; rufo-ferruginea, elytris testaceis ; 

 pectore valde cinereo-hirsuto, abdomine setose ; capite (hoc sat 

 brevi) sat sparsim haud rugulose (clypeo magis crebre), pro- 

 thorace subtiliter sparsini; elytris (his geminato-striatis) 

 sparsim paullo magis fortiter, pygidio sparsim minus fortiter, 

 punctulatis ; aiitennis 9-articulatis ; prothoracis basi sat for- 

 titer bisinuata, quam margo anticus vix plus hujus dimidio 

 latiori, angulis posticis (superne visis) vix acutis nullo modo 

 productis ; elytris apice suturali haud productis. 



Maris antennarum flabello stipite longiori, 4-articulato, — 

 articulo 1° quam ceteri vix breviori, — stipitis articulo ultimo 

 intus plus minus elongato-producto. 



Feminae antennarum flabello quam stipitis dimidium longiori, 

 4-articulato, — articulo 1° quam 2' dimidium longiori; stijjitis 

 articulo ultimo intus breviter dentato. [Long. 8, lat, 4* lines. 



The last joint of the stipes of the antennae of the male is a little 

 more elongated internally in some examples than in others, so that 

 in some it might almost be counted as a short first joint of the 

 flabellu'ra, which it would make 5-jointed. The prothorax is a 

 little less than twice as wide as long ; from the front angles (which 

 are acute and strongly prominent) the sides diverge to about the 

 middle where they are strongly rounded ; from this ])oint they 

 converge gently and sinuately (viewed from above) to the hind 

 angles. 



This species is extremely like C. testaceipennis, MacL, but with 

 very diflferent antennae, longer clypeus (less than twice as wide as 

 long), prothorax sinuately narrowed behind the middle, &c.
