LYCAENINiVE: THE GENUS NOMIADES. 949 



niiiKlle ; cross veins closing the cell transvovsc, feeble on the inner, distinct on the 

 outer halves; cell somewhat more tliiin lialf as long as the wing anil nearly four 

 times as long as broad. 



Hind wings with the costal margin having the basal third rather strongly convex, 

 beyond slightly convex, tl»e outer margin well rounded, rather full, though rounded 

 at the upper angle, the inner margin convex, the outer angle broadly rounded. Sub- 

 median nervure terminating next tlie anal angle; internal nervure terminating near the 

 middle of the inner border. 



Androconia round oval, witli a pedicel nearly one-half the length of the lamina. 



Fore tiVtiae more than two-tliinls the lengtii of tlie hind tibiae and tlve-sixt!is the 

 length of the tarsi ; last joint of the fore tarsi like those of the other legs ($),or 

 provided with connate claws, resembling those of Everes ((?). Middle tibiae five- 

 sixths the length of the hind tibiae, provided with short, tapering, scaly spurs. 

 First joint of tarsi scarcely longer than the three succeeding joints combined, these 

 diminishing in regular ratio, and the tifth scarcely longer than the third ; all furnished 

 beneath witli short and rather slender, not very frequent spines, arranged on the first 

 two or three joints in a triple, beyond in a double series, the apical spines of each 

 joint larger tlian the others ; claws small, pretty strongly falcate, especially on the 

 basal half , tapering, moderately stout, finely pointed; paronychia double, the upper 

 lobe forming a very slender, curved, pointed, cliitinous claw, running beside and slen- 

 derer than the true claw, the lower an equal, blunt-tipped, incurved, ciliate lamina, 

 two or three times as long as broad ; pulvillus wanting. 



Upper organ of male abdominal appendages mostly formed of two lunate and bul- 

 late alations, united above by their extremities and bearing beneath recurved, acicular, 

 lateral arms. Clasps greatly elongated, depressed-laminate beyond the bullatc base, 

 apically truncate and bearing an incurved acicular tooth. 



Mature caterpillar. Head rounded subquadrate, deeply cleft in the middle above, 

 the triangle much more than lialf as high as the head, and higher than broad, sepa- 

 rated from the cleft by a narrow space. Body arched longitudinally in a pretty regu- 

 lar curve with submoniliform segments, descending more abruptly in front than 

 behind, the last two or three segments being somewhat depressed; the first thoracic 

 and last abdominal segments are the longest and subequal, but also the smallest, as 

 thev are both considerably narrower than the body in the middle f viewed from above 

 the body is regularly obovate and nearly four times longer than broad. The body is 

 covered rather profusely with equally distributed, very small, flaring, stellate papillae, 

 each Ijearinga rather coarse and short, tajiering, spiculiferous hair, and with a lesser 

 number of simple minute papillae with similar but shorter hairs. Spiracles minute, 

 circular, those of the seventh and eighth abdominal segments on an upward sloping 

 line. Vesicle of the seventh abdominal segment present, but no caruncles on the 

 eighth. Legs and prolegs as usual, each of the latter with from 16-18 slender, falci- 

 form booklets. 



This group of insects is fairly well represented throughout the north 

 temperate zone, a number of species being peculiar to each continent. 

 In both it spreads from ocean to ocean, and over about an equivalent lati- 

 tudinal range. In North America it occupies a broad belt, extending, 

 with some interruptions, from the Atlantic coast, between Newfoundland 

 and Georgia, to the Pacific, from Southern Californa to Southern Alaska. 

 It has never occurred in New England itself, but only upon its borders. 



The butterflies are of a violet hue above, lustrous in the male, purplish 

 in the female, and broadly (female) or very narrowly (male) bordered on 

 the costal and outer margins with dark brown ; beneath they are slate 

 gray, with a sinuous, extra-mesial series of rather large, roundish, black
