its larva of feeding upon the cochineal insect {Coccus cacti). The larva has been 

 figured by Prof. Westwood in his ' Introduction to the Modern Classification of Insects,' 

 i. p. 392, fig. 49 (24). 



Chilocorus cacti appears to be abundant in those districts where the particular species 

 of Cactacese grow which are infested by the Coccus, or to which it has been introduced, 

 as in the case of Nopalea coccinellifera ; but I have no direct evidence myself of the 

 distribution of the Chilocorus in South America.

Chilocorus bivulnerus, Muls. Spec. Col. Trim, secur. p. 460 l ; Crotch, Trans. Am. Ent. Soc. iv. 

 p. 376 2 , and Rev. Coccin. p. 185 3 . 



Hab. Noeth Ameeica \ United States 2 3 . — Mexico, Guanajuato (SalU). 



CURINUS. 



Orcus, subgen. Curinus, Mulsant, Spec. Col. Trim, sdcur. p. 472 (1850). 

 Curinus, Crotch, Rev. Coccin. p. 190. 



A genus of doubtful value ; it, however, separates the American from the Australian 

 species of Orcus. According to Crotch it includes five representatives. 



1. Curinus caeruleus. (Tab. X. fig. 4.)

Obtained in considerable numbers ; the specimen figured is from Cordova. 



AXION. 



Exochomus, subgen. Axion, Mulsant, Spec. Col. Trim, secur. p. 477 (1850). 

 Axion, Crotch, Rev. Coccin. p. 191. 



The trivial character upon which Mulsant proposed this name for the first section of 

 Exochomus hardly warrants its adoption. Three species from the United States," as 

 well as the one from Mexico, belong to it.
