Two specimens in the British Museum formed part of 

 the Fry Collection^ and a series was sent to me by ^lessrs. 

 Staudiiiger and Bang-Haas. I have placed the species in 

 Cyclocephala rather than in Dyscinetus on account of the 

 large, smooth clypeus, of which the suture is obliterated, 

 and the shape of the mandibles^ which are bluntly produced 

 in front. In its size, shape, and general appearance the 

 insect resembles C. variolosa, Burm., but the clypeus is 

 regularly rounded and the pronotum is not margined behind. 

 The female is without the lateral expansion of the elytra 

 occurring in that of C. variolosa, and another peculiar 

 feature is found in the truncation of the uppermost tooth of 

 the front tibia of the male. 



Cyclocephala latipennis, sp. n. (PI. IV. fig. 12.) 



Piceo-nigra, glabra, nitida, lata ; capite grandi, clypeo eUiptico, 

 margine alte retiexo, antice impunctato, postice cum froute et 

 pronoto minute et sparse punctatis, hujus lateribus paulo de- 

 planatis, marginatis, basi immarginato ; scuteUo vix punctato ; 

 elytris latis, latitudiue maximo post medium ; grosse hand crebre 

 punctatis, punctis plerumque seriatim ordinatis ; pygidio glabro, 

 fere impvuictato : 



c? , tarsis anticis incrassatis, unguo majori ralde incurvato, apice 

 minute fisso. 



Long. 25 mm. ; lat. max. 14 mm.

A single male was acquired with the collection of the late 

 Alexander Fry. It is closely related to the species just 

 described, but larger, much broader, and less strongly 

 punctured, the head, pronotum. and pygidium being very 

 smooth and shining. The last joint of the front tarsus (iu 

 the male type specimen) is of enormous size.
