FAMILY HELICONIIDjE. 203 



a distinct lunule, succeeded on the outside by interrupted curved blue lines : edge 

 trimmed with black and white. 

 Head and body black : the back of the head is marked with four white spots, the first 

 pair placed at the base of the antenna". Antennae black, tipped with rufous : palpi 

 black, striped with white on the outside. Eyes blue, with a white spot posteriorly. 

 Each side of the thorax is marked with three large white spots : eoxse white ; the 

 ventral portion of five rings, white, and an abbreviated lateral white line. Legs black : 

 tarsi of the forelegs striped with white in front. Expanse of wing varies from two 

 and a half to tlrree inches. 

 This species is found accompanying the D. plexippus in the vicinity of Albany, and is 

 usually regarded as a mere variety of the same ; but the many differences in the markings, 

 taken in connection with the constancy in size of the numerous individuals I have exa- 

 mined, leave no doubt of its distinct character. 



Limenitis ursula. ( Plate xxxiii, figs. 1 & 2.) 



Color black above, black and brownish beneath : antenna; black ; knob rather slender : 

 eyes brown : head black. Behind the antenna; there are two white triangular spots, 

 and a white line beneath and outside of each eye. Thorax and abdomen black above : 

 sides of the former marked with three white spots ; on the latter, the edges of the 

 rings of the venter white, and sides marked with a wide white stripe. Outside palpi 

 white : upperside of the imperfect forefeet white. Forewings subfalcate ; outer margin 

 slightly sinuate ; nervures of the wings with four branches : posterior wings slightly 

 angulated, without tail, subtrigonal. Upper side, velvety black : forewings marked 

 with submarginal bluish and rather obsolete lunules ; apical area marked with two 

 white triangular spots ; edge trimmed with white and black : hindwings marked 

 with two rows of pale blue quadrangular spots, the third upon the inner row from 

 the anal angle being a lunate spot. Outside of these there are two rows of sublunate 

 spots, the outer white, the inner blue ; the former are placed upon the edge. Beneath, 

 the apical area is brownish, and marked with white spots, which become obsolete as 

 they extend towards the outer angle. Base of the wing bluish in some lights, and 

 marked with two brown and four blue subcostal spots : the blue spots are small, and 

 stand two and two ; the margin is trimmed with two rows of lunules, and the edge 

 with white and black. Behind the disk is brownish, similar to the apical area, and 

 the base is marked with a cluster of rufouS and blue spots. The margin inside has 

 five rufous spots surrounded with black, and two rows of lunules parallel with the 

 edge, which is trimmed with white ; nd black. 

 This species is found as far south as Georgia, yet does not appear to be commen any 

 where : it feeds on the gooseberry leaf and wild cherry, and is figured in Abbott and 

 Smith's Lepidoptera.
