H. syrichtus is the commonest and most widely ranging species of Eesperia in South 

 America, being equally common and diffuse in Central America and Mexico, in the 

 latter country reaching to the frontier States, but not passing beyond into United 

 States territory. In altitude it is found from the sea-level to a height of 7000 or 8000 

 feet in the mountains. 



Though much like the next species (H. montivaga) in general appearance, it may 

 be distinguished by the marginal row of spots being distinct and not obsolete, and the 

 base of the wing being covered with greyish-white hairs. The primaries have a distinct 

 costal fold in the male, as in H. montivaga, and the hind tibise a tuft of hairs at the 

 proximal end which is absent in the other species. 



The male genitalia have the tegumen ending in two blunt points, which are not 

 depressed or hooked ; the scaphium is very short, but well developed and serrate at 

 the end : the harpes have a rounded end, the dorsal edge of which is produced back- 

 wards in a curve, has a strongly serrate edge, and ends in a separate rod ; on the 

 inner side of the ventral edge is a lobe carrying a few strong spines (See 

 Tab. XC. fig. 27.)
