46 BRITISH BUTTERFLIES. 



of the hind border to the nearest point of the antennae, to which it acts as a support, 

 and separated from the occiput by a nearly straight, rather deep groove, with walls 

 sloping toward each other at considerably more than a right angle, the posterior the 

 more abrupt. Eyes not large nor full, naked in every part. Antennae inserted in 

 the middle of the summit, separated by a space equal to the width of the basal joint ; 

 barely longer than the abdomen, composed of about thirty-two joints, of which the 

 last twelve form a depressed, elongate club, the first three of which broaden rather 

 rapidly, but beyond them the club remains equal or even diminishes very slightly, 

 the bluntly conical tip composed of three or four joints : the club is three times as 

 broad as the stalk, and about four times as long as broad. Palpi slender, com- 

 pressed, tapering, less than twice as long as the eye, the apical joint three-fifths as 

 long as the penultimate, and provided only with recumbent scales; other joints also 

 furnished beneath with a curving fringe of very long, thick scales ; all closely 

 compressed in a vertical plane. Patagia slender, arched longitudinally, but scarcely 

 tumid, very small, about two-and-a-half times longer than broad, tapering gradually 

 and regularly, with straight sides on the basal two-thirds, beyond which they are equal, 

 bent slightly outward, so that the whole inner margin is about straight, and bluntly 

 pointed. Forewings two-thirds as long again as broad, the costal margin very gently 

 convex, less so beyond the base, the outer angle scarcely rounded off, the outer margin 

 rather broadly and regularly rounded, having a general direction of about 55°-60° 

 with the costal margin, the inner margin straight, the angle rounded. Costal nervure 

 terminating opposite the middle of the outer half of the cell, confluent for a part of the 

 time with the first superior subcostal nervure ; subcostal nervure with three superior 

 branches ; the first, arising scarcely beyond the middle of the upper margin of the 

 cell, runs at first into the costal, is completely confluent with it for a short distance, 

 and then parting from it, ends on the margin opposite the apex of the cell ; second 

 sujoerior branch arising at about one-fourth the distance from the origin of the first 

 to the apex of the cell ; and the third at a little more than half way from the origin 

 of the second to the apex of the cell, forking before the middle ; cross veins closing the 

 cell exceedingly faint and transverse, bent at a slight angle ; cell scarcely half as long 

 as the wing, and three-and-a-half times longer than broad. Hindwings with the 

 costal margin well curved, more strongly on the basal than the apical half, the outer 

 border strongly rounded, very full on the upper half, and perhaps rather more so in 

 the <? than in the ? , the medio-submedian interspace very slightly and roundly 

 emarginate, the lower median nervule finished with a very slender, thread-like tail, 

 considerably longer than the width of the interspaces at its base ; inner margin 

 rather strongly convex near the base, beyond straightly excised, the angle abrupt 

 but broad. Submedian nervure terminating at the anal angle ; internal nervure 

 terminating at about the middle of the inner border. Androconia rounded 

 quadrate, the stem less than half as long as the lamina Fore tibiae three-quarters 

 the length of the hind tibiae ; fore tarsi not so crowded with spines as on the other 

 legs, scaled beneath, the tibial spurs naked and small, smaller in the J than in the 

 ? ; the terminal joint is either like that of the other legs ( 2 ), or it is furnished at 

 tip with only a single, median, long, tapering, scarcely curving hook, without 

 paronychia or pulvillus ( <? ). Middle tibiae a little shorter than the hind pair, 

 provided at tip with long and slender tapering spines, mostly concealed by large 

 scales. First joint of tarsi as long as the others combined, the second, third, and 

 fourth diminishing regularly in size, the fifth equal to the second ; the terminal 

 joint furnished beneath with two, the other joints with three rows of moderately 

 long and slender spines, the terminal outer ones of each joint much longer than the 

 others, spur-like and curved ; claws very small, short, gently curved, tapering but 

 little, pointed ; paronychia double, the upper piece long and very slender, tapering, 

 almost filiform, incurved, and delicately pointed, the lower piece a ciliate lobe, 

 hardly longer than broad, and rounded ; pulvillus wanting Upper organ of male 

 abdominal appendages forming a short, semicircular, laminate hood, the edges 

 setose, the posterior margin entire ; lateral arms slender, very long and strongly 

 arcuate ; clasps forming a not very long, subequal, somewhat bellied ribbon, broadly 

 rounded apically. 



Egg : Very depressed echinoid-shaped, the whole upper surface almost 

 perfectly flat, flatter above than in Cyaniris (Celastr'ma), and not so high for its 

 breadth ; covered with moderately prominent, and not crowded tubercles, connected 

 by fine raised lines forming subquadrate or rhomboid cells, but with no subordinate 

 tubercles, the micropyle not sunken.
