Enthora polita, n. sp. 



Ovalis, nigra, nitidissima ; capite thorace scutelloque nigro- 

 cyaneis, vel ?eneis, cum elytris subtilissime sat crebre punc- 

 tulatis. Long. 9~UH lii^i- 



Oblong oval, very convex and sliining. All the upper 

 surface moderately thickly and extremely finely 2:)unctured, the ' 

 punctures having in the middle a minute Avhitish scale, only 

 visible with a strong magnifying power. The abdomen is 

 sparingly punctured in the middle, closely at the sides. 



The antennaj have the club composed of seven lamella? in 

 both sexes, but they are much shorter in the female thaii in 

 the male, and are of unequal length. The anterior tibia? are 

 much narrower in the male than the female ; the tarsi in the 

 female are very short. 



This species differs from that which I have determined to be 

 r^. chloradera, Blanch., in being a little longer, with much finer 

 punctuation, and in having the elytra much more distinctly 

 angular at the sides Avhen viewed laterally, and the abdomnn 

 is much less punctured. 



A considerable numlicr of examples of both sexes. 



Pwhycolus cJijpeatus, n. sp. 



Elongatus, sat convoxus, nitidus, piceus ; clypoo plica arcuata 

 transeunti, post plicam evidenter punctato, f route discrete sub- 

 tiliter jjunctulata ; thorace longitudine ^ latiori, nigro-piceo, 

 sat crebre subtilissime punctulato, augulis anticis obtusis, 

 posticis rotundatis, lateribus arcuatis longe ciliatis ; scutello 

 elongato triaugulari, la^vi, nigro-piceo ; elytris thorace panmi 

 latioribus, at 2^ longioribus, sat crebre distincte punctatis, 

 sutura Icevi ; pygidio crebre fortiter punctato ; metasterno medio 

 leviter impresso, land. Long. 2^ lin., lat. li lin. 



This sjjecies much resembles P. 'inad<igascariensis, but is 

 much narrower, and the form of the clypeus and claws present 

 almost generic differences. The forehead is quite simple, Avith- 

 out any transverse ridge behind ; the line separating the clypens 

 from the head is well marked, nearlj^ straight ; between this 

 line and the anterior margin there is a distinct plait or thickening, 

 the space l)Otwoon this plait nnd tlie nntorior niamin is dccnlv
