626 KHOPALOCERA. 



Dr. Staudinger has lent us a male example of this species, which is all we have seen 

 of it. T. seron somewhat resembles T. phidon, but has only two conspicuous hyaline 

 spots on the primaries and the underside is much more uniformly coloured ; the brand, 

 too, is absent. 



b". Primaries without hyaline spots.

 ochraceis ; capite et corpore supra viridi-ceeruleis, subtus obscuris, viridi tinctis.

II ab. Panama, Chiriqui 1 (Eibbe & Trotsch, ex Staudinger). 



Three males and one female of this species are before us, all from Chiriqui, whence 

 Dr. Staudinger's type was obtained. Moschler 2 merely gives Central America, without 

 precise locality, for his T. mardonius. Superficially, T. henricus closely resembles 

 Telegonus chiriquensis, Staudinger (antea, p. 308). but the neuration shows that it 

 belongs to the Pamphilinae and not to the Hesperiinae. There is no brand on the 

 primaries in the male, but there is a pencil of hairs at the base of the abdominal fold 

 of the secondaries in this sex. For the genitalia of the male, see Tab. CV. fig. 23. 



7. Thracides aroma. (Tab. cv. figg. 24, * ; 25, 26, $ .) 



Hesperia aroma, Hew. Descr. Sp. Hesp. p. 24 (1867) \ 



Alis fuscis, ad basin cum corpore nitide caeruleo-viridibus : subtus anticis costae dimidio basali late coloris

Bab. Costa Eica, Santa Clara valley (Zureher). — Amazons, Santarem, Para 1 . 



We have a single female of this species from Costa Rica, agreeing with others from 

 Para, whence Hewitson's type was obtained. It is a close ally of T. henricus. The 

 genitalia are figured from a South-American male ; see Tab. CV. fig. 24. 



b. The upperside of the body and the base of the wings without metallic lustre. 



c'. Primaries branded in the male, and with numerous hyaline spots, their distal half 

 with a steely lustre ; secondaries with golden spots beneath.
