1446 THE BUTTERFLIES OF NEW ENGLAND. 



reaching the rakldle of the eye, but passing a little behind it; front a little and rather 

 equall}- tnniid, surpassing soraewliat the front of the eyes, and rather more so below 

 than above; it is slightly and broadly hollowed around the antennae, separated from 

 the vertex by a scarcely impressed, straight line between the middle of the antennal 

 bases, and is rather more than twice as broad as long; the front margin is scarcely con- 

 vex, very delicately emarginate, laterally sloping oil' toward the outer edge of the eye, 

 wliere the hinder edge meets it at a rather sharj) angle ; vertex almost half as long 

 again as the front, separated from the occiput by a slightly impressed arcuate or 

 slightly bent line; it is scarcely tumid, divided into an anterior and posterior half by a 

 scarcely perceptible transverse ridge, which is arcuate in an opposite way to the poste- 

 rior border, and in front of which the vertex just attains the level of the eyes. Eyes 

 large, pretty full, round, naked, receding from each other posteriorly more than in the 

 preceding genera. Antennae inserted with the hinder edge of the base at the middle 

 of the summit, their interior edges separated from each other by aljout twice the width 

 of the basal joint, the whole antenna as long as the abdomen, composed of 38-48 

 joints, of which 20-24, that is about half, form the club, which is nearly half as long as 

 the stalk and bent in a curve at right angles near the middle; it is cylindrical at base 

 and at tip, but throughout most of its length is flattened above and subtriquetral ; the 

 first six or seven joints gradually increase in size until (seen from above) it is about equal 

 In breadth to the length of three adjoining joints, and then decreases rather more grad- 

 ually to the bluntly rounded tip, whicii is as broad as the stalk ; the curve of the club is in 

 its thickest part, and the joints in the middle of the stalk are from two to two and a half 

 times longer than broad. Palpi heavy , fully twice as long as the eye, heavily clothed with 

 long, loose, stiff, bristle-like scales and hairs, cut oft' squarely beyond the tip of middle 

 joint, and beyond which a portion of the apical joint projects, clothed with similar but 

 mostly recumbent scales ; basal joint globose, apically as broad as long, being fullest 

 antei'iorly at the tip, but not produced into a coruute appendage; middle joint com- 

 paratively slender, cylindrical, with rounded and nearly equal ends, straight, three 

 times as long as broad, and more than twice as long as the basal joint: apical joint 

 minute, cylindrical, three times as long as broad, and nearly as long as the breadth of 

 the middle joint, directed a little forwards. 



Prothoracic lobes greatly appressed, lauunate : when viewed from the front, broad, 

 fan-shaped, uearlj* twice as broad as high, the upper edge a little arcuate, the angles 

 rounded ofl'. Patagia large, in length three-fourths the breadth of the head; the pos- 

 terior lobe broad, more than half the breadtli of the base, nearly equal, largest just 

 beyond its base, nearly or quite three times as long as l)road, and Ijroadly rounded at 

 the tip. 



Fore wings (41 :7) long, triangular, twice as long as broad, the outer margin full, 

 the inner margin a little longer than it; the costal and outer margin very gently arcu- 

 ate. Costal margin thickened for more than half its length; costal uemire terminat- 

 ing opposite the tip of the cell ; first subcostal nervule originating opposite a point 

 midway between the first and second medi.an uervules, shortly before the middle of the 

 outer two-thirds of the cell ; the third and fourth uervules originating just before the 

 extremity of the cell, the fourth extending to the tip of the wing; the second originat- 

 ing midway between the first and third ; first inferior nervule originating from tlie 

 subcostal nervure, which is bent slightly downward to receive it, as far beyond the 

 origin of the fourth superior nervule as that is beyond the third, bent abruptly and 

 obliquely at its extyeme base, the bent portion obsolete ; cross vein closing the cell 

 apparent only by the bend of the ner\-ules or by a slight iucrassation at their angle and 

 striking the median nervule as far beyond its second divarication as the separation of 

 the bases of the second and third superior subcostal uervules ; second median nervule 

 arising opposite the second superior subcostal nervule ; first median slightly nearer the 

 base of the wing than to the origin of the second branch and running midway between 

 this branch and the snbmedian ; internal nervure hardly perceptible except at the 

 extreme base but having the same form and direction as in Thorybes ; cell nearly six 

 times as long as broad and about three-fifths the length of the wing.
