Lepidffptera Rhopalocera of Trinidad. 191 



Less common than preceding, but found in the same 

 situations, 



139. Callipsyche thius. 



Hyrcus thiuSy Hiib., Zutr. Ex. Schmett, ff. 743, 744 

 (1832). 



Bange. Brazil. 



Recorded by Crowfoot. 



POLYNIPHES, n. gen. 



Fore-wing with the costa very strongly arched, apex rounded, and 

 outer margin much curved. The discoidal cell very large and bowed 

 out above and below. Discocellulars strongly angled. In the ^ the 

 whole of the cell with the exception of the basal portion is occupied 

 with a band of brownish-black scales. Antenna very slightly 

 chequered on the under-side only and fairly stout for a Lycrenid. 

 Palpi upturned ; the third joint very pointed and ending in a fine 

 bristle. Fore-tibia strongly spined. 



Type Thecla dume7iilii, Godt. 



140. POLYNIPHES DUMENILII. 



Thecla dumenilii, Godart, Enc. Metb., ix, p. 677, n. 



187 (1823). 

 Thecla argiva, Hew. 



Range. VENEZUELA. 



I have twice taken this species near Port of Spain. It 

 can easily be mistaken on the wing for Tmolus alhata. 



i41. Tmolus echion. 



Papilio echion, Linn., Syst. Nat., i, 2, p. 788, n. 224 

 (1767). 



Bange. Venezuela ; Brazil, Bahia, Rio Janeiro. 



Recorded by Crowfoot. I have not seen Trinidad speci- 

 mens. In the Hewitson collection specimens of crolus, 

 Cramer, are named echion ; Crowfoot may have determined 

 specimens from this collection, and it may be that the 

 true echion, Linne, does not occur. On the other hand, 

 there is no reason to suppose the non-occurrence of any 

 Venezuelan species.
