Elytra four and one-half times as long as pronotum, and at base 

 distinctly wider than pronotum; humeri rather feebly developed;

Described from four examples, one male (type) and three females 

 received from the American Museum of Natural History. All the 

 specimens were collected at the type locality by E., H. Van Zwalu- 

 wenburg. The type was collected October 15, 1917 (Ace. No. 233-17), 

 the allotype, August 29, 1914, and the paratypes, June 1, 1917 (Ace. 

 No. 73-17), and October 5, 1917 (Ace. No. 228-17). 



This species is named in honor of Carlos E. Chardon, Commis- 

 sioner of Public Works in Porto Rico, in recognition of the en- 

 couragement of scientific research he has repeatedly displayed.
