870 THE BUTTERFLIES OK NEW ENGLAND. 



hair-bearing papillae and the spiracles, but nearer the former, is a series of round, 

 smooth, hemispherical lenticles situated in the middle of the antei'ior lialf of all the 

 segments, both thoracic and abdominal, excepting the large first thoracic segment. 

 The laterodorsal and substigmatal series of hair-bearing papillae are also repeated ou 

 the third thoracic segment, and to a certain extent on the otliers, witli certain changes 

 of position and the addition of others. No laterostigmatal series of hair-bearing 

 papillae. On the last compound abdominal segment the hairless lenticles of the lateral 

 row forms one of a series of five on eitlier side : three larger, equidistant ones placed 

 in an open curve diverging posteriorly from the opposite set, and two smaller ones 

 posterior to these, one behind and a little outside the other in the laterodorsal region. 



Mature caterpillar. Head small, smooth, rather appressed in front, rounded, a 

 few long hairs about the ocelli ; broadest above the middle, well rounded below ; tri- 

 aiigU^ half as high again as broad, reaching about two-thirds way up the front. Sec- 

 ond joint of antennae broader than long, cylindrical but tapering, third as long as the 

 second, but only half as broad, cylindrical, barely tapering; fourth a minute wartlet 

 by the side of a long, slightly curved hair. Ocelli six in number, three above nearly 

 touching each other in a slightly curved row, its convexity forward and upward, in 

 front three in a straight row along the base of the antennae, the upper being the ante- 

 rior one of the previously mentioned row, situated at a distance from each other less 

 than the diameter of one of them ; and a sixth behind the lowest of the last row, so 

 far as to form a right angle with it and the uppermost of all the ocelli ; all of equal 

 size, the sixth flat, the others convex. Labrum pretty large, fully twice as broad as 

 long, the front roundly excised to a moderate depth in the middle, either lateral half 

 well rounded in front. Mandibles short and quite broad, the edge slightly wrinkled 

 and sinuous, scarcely denticulate. Maxillary palpi with the basal joint bearing an 

 inner and an outer palp, the basal joint of the outer cylindrical, broader than long; 

 second cylindrical, twice as broad as long, and two-thirds as stout as the preceding, 

 the apical joint similar to it, but only half as broad and tapering slightly, the inner 

 palp consisting of two joints similar to the apical two of its neighbor, but a little 

 smaller. Spinneret small and linear. Labial palpi apparently consisting of a single 

 cylindrical, very slender joint. 



Body marked with longitudinal and oblique stripes and bands, pretty regularly 

 arched longitudinally, but elevated more anteriorly than posteriorly, and sloping 

 almost uniformly over the whole abdomen, but more rapidly on the last two seg- 

 ments; viewed from above elliptical, the anterior border broadly rounded, broadest 

 on the middle of the thoracic segments, tapering posteriorly very gently to the 

 seventh abdominal segment ; behind narrowing to a more sharply rounded tip ; 

 dorsal area narrow, flat or slightly sulcate; sides pretty high, tectiform; substig- 

 matal fold rather prominent, uniform ; segments not at all arched or prominent. 

 Skin delicately shagreened, the whole upper surface covered uniformly and some- 

 what frequently with minute warts, emitting short, erect, inconspicuous hairs; 

 upon the summit and anterior portion of the first thoracic segment they are twice or 

 thrice as long and stouter, and there is also a series of similar hairs upon the latero- 

 dorsal ridge and the substigmatal fold, a good many hairs to each segment. The 

 short hairs are of uniform thickness throughout, smooth and round tipped; the long 

 ones taper very slightly, are not delicately pointed, and are uniformly, distantly, and 

 very delicately spiculiferous. Spiracles very small, almost round, or a very little 

 ovate. Legs very small, tapering, the last joint very slender, the claw minute, deli- 

 cate, curving considerably and regularly. Prolegs very short, rather stout, each fur- 

 nished at tip with a double pad and each pad with a double crescentic row of rather 

 slender claws. 



Chrysalis. Viewed from above the outline of the body is a little more than twice 

 as long as broad, composed of two longitudinally contiguous, broad and short ovals, 

 one about five-eighths of the whole, formed by the abdomen, and one by the parts in 

 front ; the latter is considerably shorter and but slightly narrower than the former, 

 scarcely narrowing behind at its junction with the abdomen, narrowing somewliat
