A genus peculiar to America *, and spread over the temperate and tropical zones 

 from north to south, including the islands of the West Indies, where it is numerously 

 represented. About one hundred species have been described. 



Many species of this genus are constantly to be found in the spathes of Arums ; and 

 they are often to be met with in numbers deeply imbedded in the viscous pollen at the 

 bottom of the spathe, in company with elongate forms of Nitidulidae (Champion). 



I. Clypeus elongatus, interdum latus vel apice sinuatus ; ligula late divaricato-lobata 



mentogue late emarginato. 



1. Cyclocephala signata. 



Melolontha signata, Drury, 111. Ins. i. p. 82, t. 36. fig. 6 ; ii. Append. Ind. (1773) \ 

 Cyclocephala signata, Burm. Handb. der Ent. v. p. 43 2 . 



Hob. Beitish Hondueas, Cayo (Blancaneaux) ; Nicaeagua, Chontales (Janson) ; 

 Panama, Bugaba, Volcan de Chiriqui 2500 to 4000 feet, David (Champion). — South 

 Ameeica, Colombia, Venezuela, Peru ; West Indies 1 2 . 



The excellent description of Burmeister renders it easy to identify this species as 

 regards the male. The female may be distinguished from the same sex of the allied 

 species of similar shape and colour by the form and position of the elytral callus, it 

 being situated much behind the middle, and the margin near it is strongly sinuated and 

 depressed, the depression terminating behind with the projecting angular end of the lower 

 edge of the epipleural fold. 



Found in enormous profusion by Mr. Champion, on the savannas near David, in 

 sappy rotten Agaves. 



2. Cyclocephala collaris (?).

Hah. Beitish Hondueas, Cayo (Blancaneaux); Guatemala, Panzos (Champion). — 

 South Ameeica 1 , Ecuador ( Whymper, in coll. Bates). 



I refer this species doubtfully to C. collaris, Burm., as he does not fully describe the 

 callus and elytral dilatation of the female, which, so far as this sex is concerned, is the 



* A species has been described by Montrouzier from Woodlark Island in the Western Pacific, bnt this author 

 is so notoriously inaccurate in his generic determinations that we may fairly assume an error has been made 

 in this instance.
