nx, the short palpi, the unspurred feet, and by the position of the discoi- 

 dal and median nervures of front winj^, as well as by the robustness of all

yEg^t'ale indecisa. — Alze supra nigro-fuscae, area basali fulvescenti- 

 hirta, anticae macula discoidea; punctis tribus in serie arcuata subeostali, 

 ponecellam; duabus apud medium marginis externi, maculisque tribus 

 in serie obliqua infra ramos medianos ochraceo-albidis : ciliis omnibus 

 albis, fusco-notatis ; corpus supra fuscum, metathorace fulvescenti-hirto,

 parallelis, nigris; ciliis albis, fusco variis; corpus subtus fuscum, abdo- 

 mine cinereo-squamoso. antennis albicantibus, exp. al. 2\ in. Costa Rica.

 than to the Hesperidce; for not only does it differ remarkably from all the 

 genera of the latter family in neuration, but in its small palpi and compa- 

 ratively narrow head, thickened antennae, clumsy legs, and apparently 

 flexible abdomen.* — [Butler & Druce, Cist. EntJ i., p. 116 (1872). 



ADDENDA. 

 After the matter on p. 328 was printed, it occurred to me that 

 the method of pupation had not been described with sufficient 

 explicitness. The exposed portion of the blackened, chimney- 

 like funnel has a length of from four to six inches ; but the funnel 

 virtually extends from one to three inches below the still green and 

 growing leaves before it reaches the more solid portion of the trunk, 

 where the true burrow may be said to commence. Throughout 

 this entire length the funnel is elastic, with a tendency to con-
