Described from three specimens. Types in the collections of 

 Edward Burgess and H. K. Morrison. 



Hab., Key West, Florida. Specimens taken February 8tli and 

 9tli. This species belongs to the same section of the genus as exilis, 

 Boisd., from California, and fea, Edws., from Texas. But it can at 

 once be distinguished from the latter to which it is closely allied, 

 by the absence of the metallic blue reflection on the basal third of 

 the anterior wings above, by the coucolorous ground of the wings 

 above, and below, without the broad red bands of fea, and by the 

 presence of the two white rings in the basal third of the anterior 

 wings beneath. 



There are also other dilFerences which can be seen from the 

 description. 



I am indebted for the opportunity of describing this beautiful 

 species, to my friend Mr. Edward Burgess of the Boston Society of 

 Natural History. 



Lycaena cassias. Cram., Yar. floridensis {nov. var.). 



Expanse, $ 20 m. m. ? 22 m. ni. 



S . — Palpi above black ; beneath the first two joints white, the third black 

 tipped with white, all three clothed with thick black hairs ; antennae black 

 and white; club black, tipped with white ; body black above ; beneath white 

 with a yellowish tinge ; wings above of a deep marine blue, with a slight 

 metallic reflection ; anterior wings with a very narrow black border along the 

 costa and outer margin ; fringe black, changing to white at the inner angle. 

 Posterior wings with the disc of a lighter blue ; a black border a little wider 

 than that of the anterior wings ; fringe white ; the markings beneath show 

 slightly above ; beneath the ground color is white with brown markings ; 

 anterior wings with a series of six marginal spots between the nervules, 

 those nearest the inner angle being double ; next to these and separated by 

 the ground color, a submarginal line formed of united lunules ; this line 

 extends uninterruptedly to the fourth median nervule ; from this to the inner 

 margin it is continued by a long faint lunule ; the next line is short, extending 

 from the costa to the disco-central nervule ; the third extends from the costa 

 to the third median nervule ; these last two are formed of connected lunules. 

 The fourth is broad, uninterrupted, extending to the median nervure; from 

 the median to the third median nervule it is represented by a faint narrow 

 line. The fifth line is narrow, continuous from the costa to the inner margin. 

 The sixth line forms a broad continuous band, the sides of which are parallel 

 until they reach the median nervure, and from that point commence to diverge 

 until they reach the inner margin — widtli of the band on the median nervure .75
