1690 THE BUTTERFLIES OF NEW ENGLAND. 



the crook, pretty stout, oval, scarcely compressed, increasing in size very gradnally 

 on tlie basal half and at the extremity much more rapidly, bluntly rounded; the crook 

 consists usually of six, occasionally of more joints, forming a slender, regular, conical 

 appendage, pointed at the tip, nearly three times as long as broad, and about one-third 

 as broad as the club proper; this is from three to" four times as long as broad, largest 

 beyond the middle or at about the tenth to twelfth joint from the tip of tlie antennae; 

 middle joint of tlie stalk from two and one-half to tliree times longer tlian broad, tlie 

 third from the base of tlie antennae fully four times as long as broad. Palpi not 

 long, scarcely more tlian one and one-half times the length of the diameter of the eye 

 and pretty stput, lieavily clothed with a mass of not very long scales, beyond wiiich 

 about half of the terminal joint, clothed with recumbent scales, projects; basal 

 joint buUate, subpyriform, as bro.ad as long, largest at the tip, with atumid expansion 

 at the inner part of the front; micldle joint bullate, obovate, broadly and about equally 

 rounded at eitlier extremity, a little arcuate, twice or slightly more thau twice as long 

 as broad; apical joint seated on the middle of the tip of the second joint, straight, 

 slender, cylindrical, scarcely tapering, blunt at tip, scarcely so long as the breadth of 

 the middle joint and scarcely four times as long as broad. 



Prothoracic lobes rather small, appressed, laminate, sliaped as in Erynnis, but with 

 the upper interior corner more or less angulated ; more tlian half as long again as high 

 and about three-fourths the length of the shorter diameter of the eye. Patagia pretty 

 large, nearly as long as the breadth of the head, tlie posterior lobe fully half as broad 

 as the base and nearly twice as long, nearly equal, straight, tapering close to the tip, 

 which is rounded ofl". 



Fore wing (42 : 8, 9) twice or nearly twice as long as broad, the lower outer angle 

 falling distinctly though slightly beyond the middle of the costal margin ; the latter 

 straight, gently deflected at either extremity, tlie outer margin very gently and 

 regularly convex, the apex produced. Costal nervnre terminating at or scarcely be- 

 yond the middle of the costal margin ; the subcostal nervure moderately approximated 

 to the costal margin, the third nervule arising in the middle of the wing; cell three- 

 fifths the length of the wing, slender, subequal in the distal half; "the first median 

 nervule arises midway between the base of the wing and the second, the latter below 

 a point between the second and third subcost,al nervures; internal nervure short, 

 straight. 



Hind wing somewhat longer than broad ; the basal lobe especially much as in Polites, 

 with sometimes a slight excision of the outer margin at the inedio-subniedian inter- 

 space. Neuration as in Polites. 



Discal stigma of male unusually variable but consisting in the main of two separated, 

 slender strigae of dead black scales, that in the middle median interspace linear and 

 arcuate, that in the lower subcircular or short linear, both surrounded and sometimes 

 almost or quite concealed by overhanging, large and broad, somewhat loosely com- 

 pacted scales, and followed beyond by a field of varying size, but generally narrow, of 

 loosely compacted, erect, dusky, reflecting scales. The scales of the stigma consist of 

 a multitude of jointed threads and long delicately sjiatulate rods in tlie heart of the 

 stigma, of two-pronged rods and slender, gradually enlarged scales at the base and 

 apex of the stigma, together witli many large, simple, oval scales at the base; some- 

 times followed in the field below the stigma by long oval scales. 



Legs 2, 3, 1. Femora and tibiae clothed wholly as in Polites; femora 2, 1 3; tibiae 

 2, 3, 1 ; tarsi 3,2,1; tibiae and tarsi together equal on middle and hind legs. Fore and 

 hind femora fully two-thirds the length of the middle femora. Fore tibiae scarcely 

 tw'o-thii-ds the length of fore femora, fnlly half as long as middle tibiae, which are 

 scarcely longer than the hind pair. Leaf-like appendage of fore tibiae small and 

 slender, originating in the middle of the apical two-thirds, surpassing considerably it& 

 extremity but arcuate, nearly six times as long as broad, tapering near the tip and 

 bluntly pointed; tlie other tilnae armed at the tip with a pair of very long and slender 

 greatly unequal spurs, the hind tibiae witli a secondary, exactly similar, but slightly 

 shorter pair near the middle of tlie apical two-thirds; both tibiae have also an exterior
