Antigonus nearchus is one of the commonest of the South-American Hesperiidae, and 

 has a wide range, extending from Southern Mexico to South Brazil and in altitude 

 from the sea-level to a height of 3000 or 4000 feet in the mountains. It is an insect 

 of the clearings and open glades of the forest rather than the denser growth of trees. 

 It also frequents thinly-wooded plains. The females differ to some extent in colour, 

 some being much paler than others. 



The male genitalia have a tegumen ending in two points separated by a slight 

 depression : the harpes have a lobe starting from the middle of the dorsal edge and 

 ending in two prominent horn-like claws ; the end of each harpe is rounded and slightly 

 depressed ; from the inner side of the middle of the ventral edge a long rod proceeds, 

 which is directed forwards and slightly upwards, and reaches nearly to the end of the 

 harpes. (See Tab. LXXXVII. fig. 15.) 



SYSTASEA. 



Lintneria, W. H. Edwards, Trans. Am. Ent. Soc. vi. pp. 57, 67 (March 1877) (nee Butler Trans. 



Zool. Soc. ix. p. 620, Heterocera, 1 February, 1877). 

 Systasea (Butl. in litt.), "W. H. Edwards, Canad. Ent. ix. p. 120 (June 1877). 

 Antigonus (partim), Watson, P. Z. S. 1893, p. 57. 



This genus resembles Antigonus in having a projection or tooth at the apical angle of 

 the secondaries, but it is more truncate and not acute ; the neuration of the wino-s and 

 the structure of the hind legs are similar. The antennae, however, are not abruptly 

 bent back near the point, but are evenly curved as in Anastrus &c. The palpi have 

 a more prominent terminal joint, and the primaries are more truncate at the apex.. 

 Besides S. pulverulenta (Feld.) (=S. zampa, W. H. Edw.) the type of the genus, 

 and the species mentioned below, Antigonus excisus, Mab., A. incisus, Mab., and 

 A. variegatus, Mab., all belong here. 



The range of Systasea extends over the greater part of the Neotropical region, from 

 Southern Arizona to South Brazil and Paraguay.
