c<)iii])os('(l centrally of six or ci,i::ht racUatliiii' cells, to;:;etlicr forming; a circle, and sur- 

 rounded by pretty larjye cells, those next the circle pretty regular, the outer ones 

 lariicr, tlioir shorter axes turned toAvard the centre. 



Caterpillar at birth. Head considerably broader than the; body,* appressed speroi- 

 (lul and uniformly curved, furnished with two transverse curving roAVS of distant 

 papillae across the upper half of the face and a few below, each bearing a short club- 

 shai)ed hair. Body tapering very regulai'ly from in front l)ackward, the last segment 

 ))eing about half as In'oad as the first and distinctly forked, l)ut in a different manner 

 with each species, furnished throughout with minute, curved, club-shaped hairs seated 

 on distant ranged papilUae, viz. : on the thoracic segments in laterodorsal, lateral and 

 suprastigniatal series, one to a segment centrally placed; and a pair of infrastigmatal 

 papillae; on the abdoniinal segments, a subdorsal series, anteriorly placed; a supra- 

 lateral slightly posterior ; a suprastigmatal sliglitly anterior, all one to a segment ; and 

 a pair of infrastigmatal papillae. The body bears straight longitudinal stripes of 

 varying Avidths. 



Mature caterpillar. Head small, very regularly rounded on all parts, the upper 

 half slightly ap]>resse(l or not quite so thick as the lower portion, slightly the ])roadest 

 next the upper edge of the occllar field, slightly broader than high, the halves scarcely 

 separated by a perceptible notch above, rather full in the lower outer region ; triangle 

 reaching rather more than half Avay up the head, the base a little concave, twice as 

 high as broad, the sides a little sinuous, i-apidly tapering at the summit, depressed in a 

 groove but little distant from and subparallel to the suture at the sides ; whole head 

 profxisely coA-ered Avith minute rounded papillae, each giAing rise to a A'ery short, not 

 A^ery delicate, hair, and alternating Avith pretty deep rounded punctulations ; first joint 

 of antennae mammiform, second exceedingly short, third tAvice as long as broad, 

 cylindrical, squarely docked; ocelli, Sac in number, four forming an open curve, its 

 convexity forAvard, one being placed midAvay betAveen the uppermost and loAvermost 

 and the remaining one croAvded betAveen the first and third, counting from above; the 

 fifth is placed directly behind the fourth, which is as far from it as from the second; 

 the third larger than the others, which are equal; labrum scarcely twice as broad 

 as long, its angles I'ounded, excised in the middle of the front; mandibles very small 

 but stout, edges smooth; maxillary palpi AA'ith each successive joint smaller than the 

 previous. 



Body plump, cylindrical, thickest at the first two abdominal segments, narroAving 

 gradually behind, a little more rapidly, although still A-ery gently, in front; terminal 

 segment of equal breadth and length, conical, but truncate, the apex strongly excised 

 at the extremity of a deep medio-dorsal furroAv above, the apices of the tAvo halves 

 having the appearance of pretty large rounded tubercles; body profusely and uni- 

 formly covered Avitli irregularly distributed, minute, low, conical papillae, each giving 

 rise to a vei'y short, equal, not very delicate hair; spiracles oboAate, fully tAvice as 

 high as broad; legs rather stout, short, conical, especially the last joint; claAV rather 

 small and slender, scarcely compressed, somewhat curved ; prolegs short, quite stout. 



Chrysalis. Short, stout and high, with scarcely any prominences ; anteriorly very 

 high and abrupt, scarcely depressed on the summit of the thorax, the anterior curve 

 forming nearly a right angle Avith the loAver anterior surface ; very slightly holloAved 

 betAveen the thorax and abdomen and Avell rounded at the tip, which is nearly as 

 loAv as the under surface; vieAved from above the anterior curve is broadly rounded, 

 rather abruptly shouldered at the basal Aving tubercle ; beyond that parallel and nearly 

 straight to the middle of the abdomen, Avhen the body tapers Avith a broad curve, the 

 cremaster projecting but slightly beyond it ; the angle betAveen the front and summit 

 of the head rounded ofl', the ocellar prominences very little pronounced ; basal Aving 

 tubercle rather large, A'ery Ioav, irregular and blunt, transversely pinched a little; 

 thoi'ax with a dorsal line, slightly elcA'ated on the pronotum, slightly impressed on the 



*Sandberg describes the head of the young body, Avhich I think cannot l>e the case with 

 Oeneis bore as small in proportion to the any Ocncis at birtli.
