298 MALE GENITALIA OF NORTH AMERICAN HESPERIIDAE 



21. Pholisora ascalaphus Staudinger (Fig. 20.) 

 Biol. Cent.-Amer., Rhopalocera, pi. 89, fig. 14, (1896). 



This species has the costal fold. 



It was described as Helias ascolaphun by Staudinger^° from 

 Chiriqui, Panama. It is figured by Godman and Salvin,^' 

 who state that "it is a very common insect all over Central 

 America and southern Mexico up to an elevation of 4000 or 

 5000 feet above sea level. — In outward appearance Sltajjhylus] 

 ascalaphus is very like the North American S. hayhwsti, both 

 having a similarly shaped outer margin to the secondaries. 

 S. hayhursti is a little paler in colour, the faint marking of the 

 wings rather more plainly shown, and the palpi purer white 

 beneath." 



We have a small series of both sexes of this species from near 

 Corpus Christi, Texas (Aaron), which have been in the Academy 

 Collection over the hayhurstii label since 1884, 



The tegumen is similar to that of hayhurstii; the uncus carries 

 a similar projecting process bent sharply downward and then 

 up, ending in a hook, and bearing a tuft of hairs at its base ; the 

 valve is rounded at its apical end, in and on which it bears 

 numerous stout spines directed upwards; the aedoeagus is 

 simple. 



22. Pholisora brennus Godman and Salvin^^ (Fig. 21.) 

 Biol. Cent.-Amer., Rhopalocera, pi. 89, fig. 23, (1896). 



This species has the costal fold. Staphylus hrennus Godman 

 and Salvin^"* was described from two specimens from Chiriqui, 

 Panama, which were received from Staudinger with the manu- 

 script name hrennus Mabille. We have had specimens from the 

 Skinner Collection, in the Academy Collection for many years, 

 marked brennus, Chiriqui, Staudinger, which now turn out to 

 be imhras, so the identification of the insects of the Kunyon 

 catch, not now available, is doubtful, and the southern species 

 whicli crosses the Mexican boundary may be brennus or imbras.
