Type, allotype, and paratypes.—Cat. No. 25108, U.S.N.M. 
Described from a series of 66 specimens. The type, allotype, and 
six paratypes were collected at Paraiso, Canal Zone, Panama, by E. 
A. Schwarz between April 2 and April 18, 1911; one specimen collected 
at Paraiso, Canal Zone, Panama, April 10, 1911, and another one 
at Taboga Island, Panama, by A. H. Jennings; and the balance of 
specimens were reared from living leaves, from an undetermined plant 
collected on Taboga Island, Canal Zone, Panama, by August Busck 
July, 1907. 
Some of the paratypes from Taboga Island have the head and 
pronotum strongly violaceous.

pion at Volcan de Chiriqui, Panama, at an elevation of 2,000 to 4,000

the front, but becoming smoother on the occiput. Pronotum mod- 
erately convex, three times as wide as long at the middle, much nar- 
rower in front than behind, widest at base; sides strongly obliquely 
arcuate from base to apical angles, the edge rather strongly margined 
and the apical angles rectangular; anterior margin rather deeply,
