488 THE BUTTERFLIES OF NEAV ENGLAND. 



ten expanding into a bi-oad ovate, depressed club, two and a half times longer than 

 broad, broadly rounded at tip, the last three joints only entering into the diminution 

 of size. Palpi compact, scarcely more than half as long again as the eye and pretty 

 stout, the terminal joint about one quarter the length of the penultimate, all densely 

 clothed with scales and the ai)ical half of the upper surface of the penultimate with a 

 profuse quantity of pretty long, forward and upward reaching hairs. 



Prothoracic lobes pretty large, tumid, scarcely curving at all, larger interiorly than 

 exteriorly and tapering in height more than in length in its lateral extension, more 

 than three times as broad as long and about as high as long. Patagia very little con- 

 vex, long and rather slender, four times as long as broad, the exterior border nearly 

 straight, the interior curving a little so that the lobe tapers to a point. 



Fore wings (38 : 14) two-thirds as long again as broad, the costal margin very 

 slightly and regularly boAved, perhaps a little less strongly in the middle half ; outer 

 margin strongly sinuous, above the middle subcostal nervule slightly convex and at 

 about right angles to the outer half of the costal border, the angle rounded oft', then 

 rather sxiddenly receding at an angle of about 45°, the middle half, as far as the lowest 

 median nervule, forming a broad, rather shallow concavity; the portion below is a 

 little prominent with a well rounded curve, and the inner margin scarcely concave, the 

 angle well rounded. First superior subcostal nervule emitted a little beyond the middle 

 of the outer two-flfths of the upper margin of the cell ; second half way between the 

 origin of the first and the tip of the cell ; third at about midway between the origin of 

 the second and fourth ; the fourth at about three-fifths the distance from the tip of the 

 cell to the apex of the wings. Cell open. 



Hind wangs with the costal margin considerably and roundly expanded next the base, 

 beyond nearly straight, scarcely convex, the outer angle rounded ofl"; outer border 

 scarcely crenulate, broadly and pretty regularly rounded, except for the slight angular 

 but rounded projection at the tip of the lowest median nervule ( $ ), or the same but 

 rather flattened in the middle half of the wing and slightly more prominent at the 

 upper angle (<?) ; inner margin broadly expanded next the base, straight as far as the 

 tip of the internal nervure, where it slopes oft" rather rapidly nearly to the submedian 

 and continues its course, the angle rounded. Precostal nervure originating at a 

 little distance beyond the divarication of the costal and subcostal nervures, bent 

 strongly outward. Cell open. 



Fore legs small, cylindrical, the tibiae less than half the length of the hind tibiae; 

 tarsi about three-fifths the length of the tibiae; the whole leg covered only with scales, 

 excepting in the male where there are a very few short, laterally spreading hairs; 

 tarsi either with scarcely perceptible division into joints {^); or, largest on the 

 apical third, and consisting of five joints apparent even without denudation ; basal 

 joint nearly twice as long as the others together, the next two equal, and as large as 

 the last two together, the terminal minute and bluntly conical ; armed beneath appar- 

 ently at the incisures with an apical pair of very delicate and minute spines, none at 

 the last incisure, thos^ of the terminal joint just at the apex ( ? ). Middle tibiae very 

 slightly longer than the hind pair ; both furnished on either side of the lower surface 

 and on the upper edge of the inner side with rows of infrequent, rather short and 

 slender, diverging spines ; first joint of tarsi as long as the three succeeding together; 

 second as long as the third and fourth together, the third and fifth equal and longer 

 than the fourth; first joint with three, terminal with two, the others with four rows 

 of spines beneath, similar to those of the tibiae, the terminal ones of each joint slightly 

 longer than the others ; spurs diverging, long and very slender. Claw^s very small 

 and delicate, compressed, pretty strongly curved, finely pointed. Paronychia exceed- 

 ingly delicate, like a slightly curved hair, as long as the claws. Pulvillus minute, 

 tumid, subglobose. 



Eighth segment of the a))domen more than usually produced in the middle above, 

 covering the organs, which are more extensively prolonged than usual at this point. 

 Upper organ of male appendages large, the body tumid, roundly arched in both direc- 

 tions, a little compressed; hook considerably longer than the body, the apical half or
