Walker's original description is as usual very insufficient; it runs: 



"Castnia hesperiaris — Nigricans ; alae ochraceo fulvae, nigro strigatae et mar- 

 ginatae, anticae strigis duabus subcostalibus testaceis, posticae subtus cinereae 

 lineis undulosis nigricantibus. 



Blackish, stout. Antennae clavate, falcate, luteous towards the tips. Abdo- 

 men towards the base with somewhat ferruginous hairs. Wings orange-tawny, 

 bordered with black and with interruptedly whitish ciHae. Fore wings with a 

 trifurcate black streak which proceeds from the costa and with two irregular 

 oblique pale testaceous subcostal streaks. Hind wings with slight blackish 

 streaks ; under side gray with several slender oblique blackish undulating bands. 

 Length of the body 12 lines; of the wings 30 lines. 



a. b. Mexico. From Mr. Glennie's collection." 



The above description is not very enlightening, but Riley states 

 (1. c. p. 341) that "Felder's kollari, as Mr. Kirby informs me, is be- 

 lieved by Mr. Butler to be synonymous with Walker's hesperiaris— 3i 

 belief founded, no doubt, on comparison of the types, since Walker's 

 description is very insufficient." This reference is followed by Druce 

 who also had opportunities of seeing at least Walker's type, and as 

 Druce's figure of hesperiaris undoubtedly represents the same species 

 as Felder's figure of kollari we have little hesitation in accepting the 

 synonymy. 



Through the kindness of Dr. Dyar we have seen a copy of Blas- 

 quez's article in La Naturaleza. The generic name Teria as used by 

 him is apparently a mis-spelling of Terias Swains., as in the beginning 

 of his remarks he states that the insect in question belongs in the first 

 tribe of the Diurnals, viz. the Papilionidae, and later says that "Bois- 

 duval has described, under the name of Terias agave, a butterfly which 

 agrees in very few characters with our own." He is naturally per- 

 fectly correct in this remark, but we cannot determine from the article
