This species approaches in some particulars quite close to Cocker- 
ell’s irédescens, but it is much smaller, and the pupa-case differs in 
several particulars. It is quite similar also to Shimer’s asarwmis. His 
description is so meager that it will hardly be possible to locate his 
species unless, peradventure, the type has been preserved. 
Specimens received by the Division of Entomology at Washington, 
January 28, 1889, on ‘*Guayaba,” from A. Busck, Bayamon, Puerto 
Rico. Mr. Pergande remarks that quite a large number of the insects 
(pupe ?) had been killed by a very curious fungus. Div. Ent., No. 8422. 
Pupa-case described from numerous specimens; adult ¢ from two 
specimens.
