Hah. Mexico, Acapulco and Chilpancingo in Guerrero 

 {lliige). Several examples. 



Lacordaire (Gen. Col., viii., p. 355) adds other names 

 to the synonymy of this widely-distributed insect, and 

 mentions Guayaquil, an American locality, as coming 

 within its range. I have examined examples from the 

 Philippines, Madagascar, New Caledonia, New Ireland, 

 and the Sandwich Islands. The genus is an addition to 

 the Mexican fauna.
