1668 THE BUTTERFLIES OF NEW ENGLAXI). 



• 



subtriansular, the inner edge sti'aight and at right angles to tlie lower slightly convex 

 edge; tlie upper outer edge is considerably arcuate and the whole piece half as long 

 again as broad and as long as the longer diameter of the eye. Patagia pretty large, four- 

 fifths as long as the width of the head, the posterior lobe considerably less than half 

 as bro.ad as tlie base, but longer than it, straight, eijnal until near the tip, where it tapers 

 to the rounded extremity. 



Fore wing (42 : 15) a little (<?) or considerably (?) less than twice as long as 

 broad, the lower outer angle slightly outside the middle of the costal border; co.stal 

 margin straight beyond the slightly arched base, tlie outer margin slightly convex 

 above the raedio-submedian interspace, the apes considerably produced (<J),or con- 

 siderably convex tliroughout, the apex scarcely produced ($). Costal nervure ter- 

 minating at the middle of the costal margin ; subcostal nervure moderately approxi- 

 mate to the costal margin; the third nervule originating just beyond tlie middle of the 

 wing; cell .about three-lifths the length of the wing, slender and in apical half equal; 

 second median nervule arising opposite the base of the third subcostal nervule, tlie 

 first midway between it and the base; internal nervure rather brief, running into the 

 submediau. 



Hind wing scarcely, if at all, longer than broad, the base of the costa strongly lobed, 

 costal and inner margins of about equal length from the length of the subcostal area; 

 outer margin well rounded, with a slight, subraedian, rounded lobe, scarcely perceptible 

 In the female. First median forls distinctly more distant from the base than the 

 first subcostal and only a little beyond the b.asal third of tlie wing. 



Discal stigma of male closely I'esemljliug that of Erynnis. The scales consist, in the 

 heart, of jointed threads with long fusiform joints of large size, and of subspatulate 

 rods ; at the base and apex, of pronged or truncate rods or scales ; and in the field below 

 the stigma of large scales, generally enlarging apically and with entire margins and 

 fine striae. 



Legs 2, 3, 1. Under surface of femora and upper surface of tibiae clothed as in 

 Atalopedes, b it the upper surface of the middle and hind tibiae still more abundantly 

 furnished with conspicuous spines. Femora 2, 1, 3; tibiae 2, 3, 1 ; tarsi 2, 3, 1. Fore 

 and hind femora three-fourths the length of the middle pair. Fore tibiae two-thirds 

 the length of the fore femora, which is but little shorter than the middle and hind 

 tibiae. Leaf -like appendage of fore til)iae small, not so slender as in the previous 

 genera, originating in the middle of the apical two-thirds of the joint, scarcely sur- 

 passing its extremity, four times as long as broad, equal until near the tip, where it 

 tapers to a point and is somewhat curved. Other tilnae furnished at tip with a pair of 

 exceedingly long and slender unequal spurs, the hind tibiae also with a secondary, 

 scarcely shoi'ter, similar pair just before the middle of the apical two-thirds, both 

 tibiae with lateral spines in Atalopedes. Tarsal joints 1,2,3,4,5; fore tarsi a 

 little more than three-fourths the length of the middle, four-fifths the length of the 

 hind tibiae, a little longer than the middle femora ; all furnished with a triple row of 

 long and slender spines, those at the apex of the joints somewhat longer; basal joint 

 as long as the second, third and fourth together; second about half as long as the 

 basal. Claws pretty small, delicate, tapering, pointed, pretty strongly and regularly 

 arcuate. Pad small, transverse. Paronychia bifid, the upper lobe a large, broad, com- 

 pressed, enslform plate, as long as the claws, its lower border nearly straight, its 

 upper curving like the claw; lower lobe a minute, triangular, very inconspicuous pro- 

 jection. 



Male abdomin-il appendages : Upper organ pretty large, strongly curved, appressed, 

 tapering, convex transversely. Centrum strongly arched near the middle, l)eyoud which 

 the parts are nearly horizontal ; hook single, depressed, regularly tapering ; lateral arms 

 connate, similar to the hook, but much slenderer and curved in an opposite direction. 

 Clasps large, as long as tlie upper organ, broad, convex, tapering a little, terminating 

 in a rounded lobe bearing au upturned, pointed tooth. 



Egg. Pretty high, broadest at the base, narrowing regularly but not greatly to the 

 summit, which is broadly rounded and a little flattened; under surface, and incou-
