414 THE BUTTERFLIES OF ^'EW ENGLAND. 



Prothoracic lol)es moderatelj' large, scarcely arched, not very tumid, the anterior 

 border straight, the posterior and superior slightly curved, well rounded and tapering 

 nearly equally at either end, about five times as broad as long and sliglitly higher than 

 broad. Patagia about twice as long as broad, very slightly tumid, very broad, well 

 rounded and nearly circular at l^ase, the posterior lobe projecting as a straight, nar- 

 row, greatly tapering blade, the tip curved sliglitly downward and bluntly pointed. 



Fore Avings (38 : 13) rather more than half as long again as l)road, the costal margin 

 bent roundly just beyond the base, beyond it straight nearly to the tip, Avhich is curved 

 downward a little; outer margin slightly crennlate, the upper portion, above the 

 middle of the loAver subcostal interspace, a very little concave and having a general 

 direction -at a little less than a right angle Avith the middle of the costal margin ; 

 behind this suddenly receding to the middle of the succeeding interspace, and then 

 passing in a slight, broad, concave sAvell to just beloAV the loAver median nervnle, Avhere 

 it is again slightly angnlated : the inner border is straight, the angle broadly rounded. 

 First superior branch of the subcostal nervure emitted a little beyond the middle of 

 the outer half of the upper margin of the cell ; second half Avay betAveen the base of 

 tlie first and the tip of the cell ; both a little further from the base in the male tliau in 

 the female; third rather less than one-third, fourth a little more than one-half the 

 distance fromthe tip of the cell to the apex of the Aving; second inferior branch of 

 the subcostal nervure arising from one-fourth to one-third Avay doAvn the cell ; the 

 latter considerably less than half as long as the Aving, and less than three times as long 

 as broad; the distance from the origin of the second median nervnle to the vein 

 closing the cell is one-half that betAveen the bases of the first and second nervules. 

 Hind Avings Avith the costal border scarcely convex, the outer l)order delicately crenn- 

 late, rather broadly curved, protuberant as a slight angular dentation at tlie tip 

 of the upper median nervnle ; the inner border scarcely convex for nearly tAvo- thirds 

 its distance beyond the basal expansion, then, roundly excised for a short distance, it 

 continues its direction nearly parallel to the former portion, the outer angle abrupt 

 but rounded. Precostal nervure directed straight upAvard, not inclined in either direc- 

 tion, originating considerably beyond the divarication of the subcostal from the costal 

 nervure. Cell closed by a feeble vein. 



Fore legs small, cylindrical, a little depressed, clothed Avitli a depressed, bnsliy bunch 

 of long spreading hairs, rather heavier in the male tlian in tlie female; the tibia about 

 half the length of the hind tibia ; tarsi scarcely shorter than the tibia, in tlie male con- 

 sisting of a single joint, Avith exceedingly slight indications of any divisions and 

 AvhoUy unarmed; in the female distinctly composed of five joints, of Avhich the first is 

 tAvice as long as all the others united, and these successively shorter, eacli armed 

 beneath at its tip Avith a pair of minute slender spines. Middle and hind tibiae of 

 equal length, furnished on either side beneath and on the upper portion of the inner 

 side Avith a roAv of infrequent, long and pretty slender, slightly spreading spines, the 

 terminal ones of the inferior roAvs prolonged to long and very slender spurs ; tarsi 

 having the first joint nearly as long as the others taken together, the second, third and 

 fourth successively decreasing in size, the fourth half as long as, and the fifth a little 

 longer than, the second; joints furnished beneath Avith four, the last Avith only two, 

 roAvs of small and slender spines, the terminal ones on each joint scarcely longer than 

 the others. ClaAVS delicate, not very long, tapering to a fine point, pretty strongly 

 curved. Paronychia slender, tapering, nearly as long as the claAvs, curving less and 

 nearly straight on the apical half. Pulvillns Avanting. Last joint of tarsi furnished 

 above at the tip Avith four very minute and slender, but pretty long, sliglitly diverg- 

 ing, aciculate spines, directed betAveen the claAVS. 



Appendages of the male abdomen : upper organ small but very broad, and very broadly 

 rounded, both transversely and longitudinally, the hook as long as the body, rapidly 

 narroAving on the basal half, beyond nearly equal. Clasps of moderate size, bnllate, 

 twice as long as broad, nearly ecpial on the basal three-fonrths, beyond tapering 

 rapidly to a point, the upper basal process parallel to tlie clasp, but incurved more 

 than it, large, expanded at base, tapering beyond to a point ; interior finger pretty large 

 and long, tapering, extending along the middle of tlie clasp and reaching to its tip.
