 — South America to Brazil ; Trinidad. 



This insect is commoner than T. salius, but has a similar distribution. Our 

 series includes about sixty specimens, in all of which the C-shaped spot in the cell 

 is prominent ; in one or two cases it is divided into two. The variation in size is very 

 great, some of the males being extremely small and several of the females exceedingly 

 large — T. longirostris, in fact, varying more in this respect than any other Hesperiid 

 we are acquainted with. 



The spots on the secondaries are variable in number, as in T. salius, and occasion- 

 ally are absent. In the female the outer spot on the secondaries is often large and 

 quadrate, which does not appear to be the case in any of the varieties of T. salius. 

 We have a single male from Chiriqui which has the underside of a uniform fuscous 

 colour, with the costa and apex of the primaries, and the secondaries, except along 

 the inner margin, strongly suffused with purple (fig. 9) ; we look upon this as an 

 extreme variety, since having dissected the genitalia we find that they agree with those 

 of the present species. 



Hewitson has wrongly figured this species as the female of Eesperia fischeri, Latr., 

 of which we possess examples of both sexes. 



We figure a typical male from Atoyac, also a variety from Chiriqui, and the genitalia, 

 for which see Tab. CVI. fig. 8.

Eab. Panama, Chiriqui (ex Staudinger). — Guiana; Amazons 1 . 



Our collection contains four males of this species, one only of which is from Central 

 America. They agree well with Hewitson's figure. T. chiomara is very like T. salius, 

 but differs from it in having the costa and apex of the primaries and the secondaries, 

 except at the anal angle, reddish-brown beneath. The genitalia also differ in form, 

 see Tab. CVI. fig. 10.
