LIGNYOSTOLA. 



Lignyostola, Mabille, Le Nat. x. p. 221 (1888) ; Wats. P. Z. S. 1893, p. 39. 



The type of this genus is Telegonus lacydus, Druce, red escribed by M. Mabille as 

 Lignyostola pemphigargyra, and with it L. crinisus (Cr.) seems to be fairly congeneric. 

 Eudamus formosus, Feld., included in this genus by Mr. Watson, belongs rather to 

 Paradros, where we have placed it. 



In many points of structure Lignyostola resembles Paradros, having similar antennge 

 and palpi ; the outline of the wings, too, is much the same. In Lignyostola the third 

 segment is shorter in proportion to the second than it is in Paradros, and the disco- 

 cellulars are more oblique to the axis of the wing. The hind tibiae have an abdominal 

 as well as a dorsal fringe. Both genera have a costal fold to the primaries of the male. 



The genus has a wide range in South America, but we have not traced it north of 

 Nicaragua in Central America.

 — Colombia; Upper Amazons Valley ; Eastern Peru 1 . 



Mr. Druce 's types of this species now before us formed part of Mr. Bartlett's collection 

 made on the Ucayali Eiver in Eastern Peru K Another specimen, formerly in Mr. Druce's 

 possession, came from Villa Nova in the Valley of 'the Amazons. We have also a 

 specimen from San Martin in the Llanos of the Rio Meta in Colombia. With these 

 southern specimens several from our country agree, including one lent us by 

 Dr. Staudinger with M. Mabilie's name Lignyostola pemphigargyra attached to it. 



Though the wings are of a uniform dark brown, the species may readily be recognized 

 by the shape of the palpi and their ferruginous colour. 



The male genitalia have a cleft tegumen; the scaphium is well developed; the 

 harpes are truncate, the terminal edge concave, a prominent tooth arising from the 

 middle, the lower corner is sharp-pointed, and the upper corner has a series of fine 

 but distinct serrations. (See Tab. LXXXI. fig. 25.)
