We possess four male examples of A. pittacus, derived from the same source as our 

 specimens of the preceding species, which it closely resembles. A. pittacus differs, 

 however, from that insect in having more spots on the primaries, and there is also a 

 transverse macular band on the secondaries. For the genitalia of the male, see 

 Tab. XCV. fig. 13.

Hab. North America, Arizona ^—Mexico, Northern Sonora (Morrison). 



We have received a female example of this species from Morrison under the name of 

 Pamphila python, and it agrees fairly well with Edwards's description. It is possible 

 that the insect may prove to belong to A. pittacus, the female of which is unknown to 

 us. Mr. Edwards's description of P. python was based upon a single specimen of that 

 sex from. Arizona. 



LERODEA. 



Lerodea, Scudder, Eep. Peabody Ac. Sci. iv. p. 80 (1872) ; Watson, P. Z. S. 1893, p. 106 (part.). 



This genus, the type of which is Hesperia eufala, Edw., is perhaps most nearly allied 

 to Atrytonopsis and Prenes. It differs from the latter, however, in having a shorter 

 crook to the antennae; the primaries are less elongate, not hollowed on the outer 

 margin, the cell is relatively shorter, and the genitalia of the type, too, are very 

 differently formed in the male. There is no trace of a brand on the primaries in 

 this sex. 



The antennae are considerably less than half the length of the costa, and have a 

 stout club, terminating in a short crook. The palpi have the third joint short, stout, 

 erect, and bluntly conical. The primaries are narrow and somewhat pointed at the 

 tip ; the cell is considerably less than two-thirds the length of the costa ; the disco- 

 cellulars are oblique, the lower one shorter than the upper ; the lower radial is slightly 

 depressed at the base ; the first branch arises from the middle of the median nervure, 

 the second from close to the lower angle of the cell. The secondaries are slightly 

 lobed at the anal angle ; the discocellulars are very faint. The body is robust. The 

 middle and hind tibiae are spined ; the latter have two pairs of spurs. 



Lerodea has a wide range in America, extending from the United States to Chili
