 quatuor vel quinque, una in cellula, tribus vel quatuor in linea obliqua infra earn, secunda maxima et 

 subquadrata, punctisque tribus in linea transversa subapiealibus, omnibus albo-hyalinis ; posticis maculis 

 tribus (interdum duabus) coloris ejusdem in serie transversa ultra cellulam, exteriore maxima : subtus

This insect closely resembles Thespieus maeareus, but the hairs on the upperside of 

 the body and at the base of the wings are obscure ochreous, and not bluish as in the 

 latter species, and the males have a very differently shaped inconspicuous brand covered 

 by the larger scales. The spots on the disc of the primaries are larger in some specimens 

 than in others, and the outer one of the transverse series on the secondaries is always 

 the largest ; the females occasionally have the outer one only present on these wings. 



Four males from different localities have been dissected. We figure a male from 

 Chiriqui and a female from Costa Rica ; also the fore wing of the male, to show the 

 position of the brand (Tab. XCVII. fig. 5), and the genitalia, for which see Tab. XCVII.

2. Vacerra egla. (Tab. xcvu. figg. 9, 10, 11, e .) 



Hesperia egla, Hew. Ann. & Mag. Nat. Hist. (4) xix. p. 82 \ 



Alis fuscis, stigmate concolore, anticis maculis quinque, duabus in cellula elongatis, tribus in serie obliqua infra 

 earn, ea in medio maxima, punctisque tribus in linea transversa subapiealibus, omnibus albo-hyalinits ; 

 posticis maculis tribus in linea transversa ultra cellulam exteriore geminata coloris ejusdem : subtus fere 

 ut supra, .sed dilutioribus, anticis macula margini interno proxima multo majore ; ciliis griseis. 



$ mari similis, sed anticis maculis in cellula confluentibus.

Six males and two females of this species are before us, two of which have been 

 lent by Dr. Staudinger. The males are easily separated from those of V. litana by 

 the primaries having the hyaline spot in the cell divided into two, and by the uniform 

 width of the spots in the transverse band of the secondaries ; the females can only be 

 distinguished from the corresponding sex of that species by the position of the spots 

 on the secondaries and the unspotted fringe. We figure a male from Chiriqui. For 

 the genitalia, see Tab. XCVII. fig. 11.
