454 KHOPALOCEKA. 



A common species throughout the lowands of Mexico and Central America up to an 

 elevation of about 3000 feet. In South America it extends over the whole of the 

 tropical portion and as far south as Cordova in Argentina, where the late F. W. White 

 obtained specimens. 



The Hesperids collected by Mr. H. H. Smith in the West Indian Islands of St. Vincent, 

 Grenadines, and Grenada, and referred by us to this species (P. Z. S. 1896, p. 520), 

 differ to some extent from the continental form. The St. Vincent specimens are much 

 darker and have distinct spots over the outer portion of the wings beneath. Those 

 from the Grenadines and Grenada are intermediate. 



The male genitalia have a tegumen ending in two divergent points. The harpes are 

 widely cleft at the end, dividing each into two lobes : the upper lobe of the left harpe 

 is short and acute at the upper terminal corner, the lower edge being rounded, the 

 lower lobe longer and somewhat spatulate: the right harpe has the upper lobe 

 ending in a thickened edge, from which proceed long hairs; the dorsal edge of the 

 lower lobe is serrate towards the end. (See Tab. XCI. fig. 3.)

Bab. Mexico, Acapulco, Rincon, Dos Arroyos, Chilpancingo, La Venta, and 

 Acaguizotla, all in Guerrero (H. H. Smith) ; Guatemala, Polochic and Chisoy Valleys 

 (F. J). G, & 0. 8.). — Colombia l and South America generally to Brazil ; Cuba. 



The peculiar dark velvety markings on the primaries of this species render it readily 

 distinguishable, but in general coloration the insect much resembles several species 

 of the genus Achlyodes. The blunt antennas seem to remove it from that group of the 

 family and to justify its being placed here. 



All our Mexican specimens were captured by Mr. Smith in the State of Guerrero, 

 where the species would appear to be common. In Guatemala we only found it in 

 the valleys of the interior at an elevation of about 3000 feet. No specimens have 

 reached us from any other part of Central America, but in Colombia, whence Moschler's 

 types were obtained, it is found, and in many other parts of South America also. 



The male genitalia have a tegumen ending in two strong depressed hooks, and at 

 their base arises a somewhat spatule-shaped lobe from the middle line. The harpes are 

 asymmetrical: the left harpe is truncate, with a strong thorn-like tooth rising from 

 'the dorsal edge near the end ; the right harpe has a similar tooth, but in addition a lobe 

 on the dorsal edge, broad at the base and with a blunt point directed backwards 

 (See Tab, XCI. fig. 6.)
