204 Mr. W. J. Kaye's Catalogue of the 



Not common. 



Butler's species harti has no logical standing and must 

 be sunk under polyhymnia. His types $ and $ are 

 described from Trinidad specimens, but it is impossible 

 to differentiate the $ from ^ 'polyliymnia, and the t 

 agrees with Felder's description, but there is no ^ specimen 

 in the British Museum for comparison. It is highly 

 probable that some of Butler's characters are characters 

 brought about by the age of the specimens with which 

 he was comparing the Trinidad fresh examples. 



186. Kricogonia lyside. 



Colias lyside, Godt., Enc. Meth., ix, p. 98, n. 80 



(1819). 

 Rhodocera terissa, Luc, Rev. Zool., 1852, p. 429. 

 Range. Jamaica ; Cuba ; Hayti ; Central America. 



The occurrence of this species in Trinidad is remarkable 

 and suggests accidental introduction or migration. The 

 single specimen, a $ , came to me in a batch of papered 

 insects, and there is no doubt about the insect having 

 occurred. 



A note concerning this species may here be not out 

 of place. The ^ sex was described by Lucas and the 

 $ sex was described independently by Godart. My 

 correspondent, Mr. C. B. Taylor, in Kingston, Jamaica, 

 has often bred this species, and has proved frequently that 

 terissa is only the ^ of lyside.
