and the series of marginal black spots faintly and very narrowly 

 bordered with white. 



Expanse of wings 2| inches. 



One example. 



Near to I), nestmachus, Boisduval, but considerably less 

 maculate. 



Lethe sicelides. 



Male. — Upperside brown. Anterior wings with a broad 

 darker brown indistinct band on the outer margin, and a large 

 triangular indistinct sericeous patch, having its base on the 

 inner margin and towards its apex extending beyond the 

 end of the cell. Posterior wings without any tufts of hair 

 within the cell; a submarginal row of four dark brown spots 

 without any white centre, and surrounded by pale brown 

 rings, the spot nearest the apex and tlie next but one being 

 the largest. 



Underside. Anterior wings with the cell crossed in the 

 middle by two dark bars, the inner bar thicker than the outer 

 and the space between being pale; a dark line at the end of 

 the cell ; two indistinct spots underneath each other towards 

 the apex, with white centres and surrounded by pale rings; 

 the other markings on the anterior and those on the posterior 

 wings very nearly the same as on L. siceh's, Hewitson, but on 

 the posterior wings the spot (in the submarginal row of spots) 

 between the middle and lowest median nervules is much 

 smaller than in L. si'ceh's, and the outer of the two narrow bands 

 which cross the wings is bifid at its lower end and further 

 apart from the inner band. 



Expanse of wings 2| inches. 



Three specimens. 



Very like L. sicelis in general appearance, but belonging to a 

 different section of the genus. The large sericeous patch on 

 the anterior wings and the absence of the tufts on the poste- 

 rior wings distinguish it from that species. 



XXXIII. — On a New Species of Aplysiid^e Ji-oni Jamaica. 

 By T. D. A. Cockerell, F.Z.S., Curator of the Museum 

 of the Institute of Jamaica. 



On January 19th Mr. Verona Carter brought to the museum 

 a remarkable Aplysiid which he had caught at Kingston. 

 The specimen was alive in a bowl of water, so I made a 

 description of it before putting it in spirit. It was well that
