LYCAENINAE: THE GENUS MITURA. 857 



the cell either nearly transverse, the two halves scarcely bent and very feeble, except- 

 insr next the main branches, striking the subcostal opposite the origin of the last 

 superior branch ($); or strongly bent, the lower half transverse and feeble, the 

 upper oblique and strong, striking the subcostal nervure farther beyond the origin 

 of the last superior branch, than that is beyond the first (<J). Cell scarcely half as 

 long as the wing and more than three times longer than broad. 



Hind wings witli the costal margin considerably and roundly expanded at base, 

 nearly straight in the middle h.alf , beyond curving gradually backward, broadly round- 

 ing the outer angle ; outer margin rather broadly and regularly rounded, slightly fuller 

 in the $ than in the $ , with a slender, thread-like tail at the lower median nervule, 

 half as long again as the width of an interspace at its base, and with a secondary tail 

 at the middle median nervule, forming only a slight, not slender projection ; inner 

 margin not very broadly convex, roundly and not deeply emarginate just before the 

 tip. Sul)mcdian nervure terminating on the outer border, just beyond the anal angle; 

 internal nervure terminating beyond the middle of the outer border. 



Androconia remarkably stout, less than three times as long as broad, quadrangular, 

 with equal sides, the stalk very short. 



Fore tibiae from three-quarters to four-fifths the length of the hind tibiae, and of 

 the same length as the fore tarsi; fore legs similarly developed in the two sexes, ex- 

 cepting the last tarsal joint, which is either like that of the other legs ($),orvery 

 small, bearing at its unenlarged tip only a pair of nearly straight spines, the continua- 

 tion of the row at the side, and having its upper surface covered with very short and 

 close hairs {$)■-, otherwise, and excepting that in both sexes the tibial spurs are 

 naked, the fore legs difler from the others in little but their size. Femora thinly 

 fringed with hairs, rather more thickly on the fore legs, and especially in the male; 

 middle tibiae but little shorter than the hind pair, armed at the tip with rather short 

 spurs, almost completely concealed by scales, but witli no spines, or at least none that 

 emerge above the scales; first joint of tarsi equalling the three succeeding, the sec- 

 ond and third equal, shorter thau the fifth and longer than the fourth; armed beneath, 

 on either side, with a clustered row of small, crowded, rather slender spines, a single 

 one on either side of the apex of each joint longer and spur-like; under surface of all 

 the joints but the basal devoid of scales. Claws small, compressed, slender, taper- 

 ing, finely pointed, rather strongly and regularly curved; paronychia simple, rather 

 stout, equal, as long as the claw, nearly sti-aight; pulvillus very minute, projecting. 



Male abdominal appendages having the upper organ much as iu Thecla, but cleft 

 above in such a way that the notch terminates sharply; the lateral arms are less 

 delicately pointed. Clasps gibbous at base, tapering rapidly beyond to a finely drawn 

 out point. 



Egg. Greatly depressed echinoitl-shaped, as broad at summit as at base, 

 the summit slightly depressed; studded abundantly with rather large, greatly 

 elevated conical prominences, connected with the neighboring ones bj' rather 

 obscure and slight but somewhat coarse ridges, which run up the sides of tlie prom- 

 inences as buttresses and give them the appearance of miniature volcanic cones ; to 

 some extent they are disposed in regular rows. Mieropyle rosette not greatly 

 depressed, rather large, composed of a number of nearly uniform oval cells, divided 

 by delicate lines. 



Caterpillar at birth. Body much as in Thecla. Laterodorsal series of hairs con- 

 sisting of two nearly equal, centrally situated papillae, side by side, the hairs borne by 

 them spiculiferous and of equal length; and besides these a supralateral series at 

 the anterior margin, supporting a shorter hair. Iu this genus is also found a latero- 

 stigmatal series of papillae similar to the last mentioned and situated like them at the 

 anterior margin, bearing a spiculiferous hair but slightly shorter than those of the 

 laterodorsal series. Beneath the stigmata is on each segment a cluster of four papil- 

 lae, bearing hairs of nearly equal length directed outward and about half as long as 

 the width of the body. 

 Mature caterpillar. Body largest anteriorly, very gently tapering, the last or last
