294 THE BUTTERFLIES OF THE 



The above description was taken from larvse fed on 

 Desmodium. Those that fed on clover differed in color- 

 ation, as follows : color russet, varying towards vinous, 

 interspersed with green ; at third moult some were pale 

 green dorsally, the white being caused by the tubercles, 

 the sides vinous, the dorsal stripe and oblique lines 

 vinous ; others had the back as well as the sides vinous, 

 and this variation and character persisted to maturity. 

 The chrysalides of these larvae were sordid white on the 

 upper surface and lower side of the abdomen, the former 

 specked v»?ith brown ; dorsal stripe brown, as were also 

 the dots ; under side of thorax and of head-ca.'^e, and the 

 whole of the wing-cases, apple-green. (See Addenda.)

125. Lyc^na Filenus, Poey. 



Expanse of wings from .75 to .95 of an inch. 



Upper side of the male blue, with a slight black 

 border; fringes white. In both sexes there is a small 

 round black spot near the outer edge of the hind wings. 

 The female is blackish brown, with the middle area of 

 the basal half of both wings washed with blue. 



Under side ash-gray, usually paler in the male tlian 

 in the female, with a discoidal crescent on the middle of 

 each wing, bordered on each side with white ; and three 

 sinuous common bands, formed of small black spots 

 circled with white, of which the outer are a little hvss 

 distinct and somewhat sagittate. The space which sepa- 

 rates the inner band from the median is usually whiter 

 than the rest of the surface, and forms a band of small 

 white quadrangular spots. The base of the hind wings 

 has a transverse row of three very black points annulate
