XIII. Descriptions of neic species of LjCEenid^e, from 

 his own Collection. By W. C. Hewitson,F.L.S. 



[Read 2nd March, 1874.] 



Felder's genus Pseudodipsas contains insects of very 

 different construction, and I propose to follow Mr. Moore 

 in dividing it into three genera, — Pseudodipsas, Poritia 

 and Lyccenesthes — and to describe several new species in 

 each of them. 



Pseudodipsas lone has three branches from the sub- 

 costal nervure. I do not in these remarks count (as 

 Edward Doubleday did) the terminatiou of the subcostal 

 nervure itself as a fourth branch. 



Poritia of Moore, which includes, together with P. Heivit- 

 soni, P. SumatrcB and P. Erycinoides of Felder (counting 

 in the same way), has two branches only from the sub- 

 costal nervure. Mr. Moore says that there are four ; but 

 I cannot understand how he comes to this conclusion, 

 unless he counts one of the discoidal nervures. 



In many of the Lycanidce the first branch from the 

 subcostal nervure, which is absorbed by the costal nervure 

 in one example of the same species, is fi-ee in another. 

 I cannot, however, trace any such absorption in the many 

 specimens which I have examined in this genus. 



Lyccenesthes has three subcostal branches ; Moore says 

 five, but in this case it is clear that he has counted a dis- 

 coidal nervure as one. This genus, which has the appear- 

 ance of a Thecla, with the neuration of Lycana, will 

 contain Felder 's P. Lyccenoides (^Bengalensis, Moore), 

 P. Sylvanus of Drury, and P. Larydas of Cramer, and 

 several aUied species Avhicli I now describe. L. Emolus 

 of Trimen (I quote him for the name, feeling, as he does, 

 a doubt as to its being Godart's species), which he likens 

 to a Thecla, noting its rapid flight, his L. Otacilia, and 

 L. Amarah of Guerin, will form part of this genus. All 

 the species which I have examined have, when fresh, 

 three tail-like tufts of hair (noticed by Moore) instead of 

 the more substantial tails of other genera; and this will, 

 I think, form an excellent characteristic of the genus,
