MELOLONTIIID.E. 



Enthora polita, n. sp. 



Ovalis, nigra, nitidissima ; capite thorace scutelloque nigro- 

 cyaneis, vol a?neis, cum elytris subtilissitne sat crebre punc- 

 tulatis. Long. 9-lOi- lin. 



Oblong oval, very convex and sliining. All the upper 

 surface moderately thickly and extremely finely punctured, the 

 punctures having in the middle a minute whitish scale, only 

 visible with a strong magnifying power. The abdomen is 

 sparingly punctured in the middle, closely at the sides. 



The antenuJB have the club composed of seven lamella; in 

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

 the male, and are of unequal length. The anterior tibial 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 

 E. chlorodera, Blanch., in being a little longer, with much finer 

 punctuation, and in having the elytra much more distinctly 

 angular at the sides when viewed laterallj-, and the abdomen 

 is much less punctured, 



A considerable niunber of examples of both sexes. 



ParJnjcolns ch/pcatus, n. sp. 



Elongatus, sat convexus, nitidus, piceus ; clypeo plica arcuata 

 transeunti, post plicam evidenter punctato, fronte discrete sub- 

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

 sat crebre subtilissime punctulato, augulis anticis obtusis, 

 posticis rotundatis, lateribus arcuatis longe ciliatis ; scutello 

 elongato triangulari, lajvi, nigro-piceo ; elytris thorace pan mi 

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

 suturti Isevi ; pygidio crebre fortiter pimctato ; metasterno medio 

 leviter impresso, la;vi. Long. 2| lin., lat. It lin. 



This species much resemliles P. lamlagascmiensts, but is 

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

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

 out any transverse ridge behind : the line separating the clypeus 

 from the head is well marked, nearly straight ; between this 

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

 the space between this plait and tlie anterior margin is dei'iily
