1244 THE BUTTERFLIES OF NEW ENGLAND. 



figure), which is uearly as broad and as long as the globular basal attachnieut to the 

 membrane; they are smaller than the ordinary scales, the lamina being only .042 mm. 

 in length. 



Egg (66 : t) irregularly granulosa, but almost completely hidden by the coating of 

 salmon red oily material by which it is besmeared, concealing the natural dull watery 

 olive color of the whole, as well as not permitting the micropyle to be distinctly seen. 

 In one there seemed to be a close rosette of 6-8 kite-shaped cells forming a sunken 

 depression about .05 mm. in diameter; and minute cells of a circular shape appeared 

 to surround it. The egg is 1.05 mm. in diameter and in height. 



Caterpillai. First stage (72:7). Head (80: 1) shining olive black, the mouth 

 parts the same but the base of the labium and antennae dull ochraceous. Body uni- 

 form brown ochraceous, dorsal shield of first and last segments and tubercles dark 

 olive brown; bristles nearly as long as the diameter of the body, black, with extreme 

 tip white. They have a scarcely perceptible taper and at tip bear an oval bulb of 

 nearly the diameter of the base of the tubercle and colorless, giving it a whitish ap- 

 pearance against the black stem. Legs blackish; prolegs blackish brown. Length, 

 2.5 mm. ; breadth, A mm. ; length of bristles, .3 mm. 



Second stage. Head (80 : 2) shining black covered sparsely with black hairs. Body a 

 little stouter on anterior tlian on posterior half, dark umber brown, armed with smooth, 

 bluntly pointed conical tentacles ; there is a supralateral row from the second thoracic 

 to the ninth abdominal segments inclusive, those of the first abdominal, and still more 

 those of the thoracic segments, a little more closely approximated than the others ; they 

 vary in size, the third abdominal being slightly smaller than the second, fourth, fifth 

 and sixth abdominal, which in theii- turn are scarcely more than half as long as the re- 

 maining ; they are all of a orange color, the longest inf uscated at the tip, and all bearing 

 a few scattered, short, flue, black hairs most abundant apically ; there is an obliquely 

 ascending laterostigraatal row of similar but duller colored tentacles on the thoracic 

 and first abdominal segments, that of the first thoracic segment more slenderly taper- 

 ing than any others on the body and more than twice as long as the others which slightly 

 decrease in size posteriorly ; there is also an iuf rastigmatal tubercle (similar to the 

 laterostigraatal one of the second thoracic segment) on the second abdominal segment, 

 which is so nearly stigmatal as to slightly displace the spiracle, and a row of small, 

 equal, stigmato-ventral tubercles on the third to eighth abdominal segments at the base 

 of the prolegs ; legs black ; prolegs of the color of the body ; spiracles minute blackish ; 

 a very few short, black hairs are scattered over the body. Prothoracic shield blackish 

 castaneous, shining, three times as broad as long, the lateral edges equally rounded; 

 lips of osmateria very dull orange ; aual plate minute, black, bristling with black hairs. 

 Length, 9 mm. ; breadth, 2 mm. ; length of long tentacles, 1.2 mm. 



Third stage (76 : 21 ; 80 : 3). In this stage the caterpillar does not appear to differ 

 from the preceding excepting in the accentuation of the distinctions between different 

 parts of the body ; the body color grows a little darker as do most of the tubercles, but 

 those of the supralateral series become a brighter orange, excepting upon the sixth to 

 ninth abdominal segments ; the diflerence in the size of all the filaments is also increased 

 and those of the first thoracic and sixth abdominal segments become slightly curved. 

 The caterpillars have now reached a lengtli of 11 mm. and a breadth of 2 mm., while 

 the long anterior tentacles measure 2.5 mm. and the supralateral tentacles of the sixth 

 abdominal segment, .85 mm. 



Fourth stage (80 : 4). This agrees very closely with the succeeding stage, the only 

 noticeable difference being that a suprastigmatal row of coral red spots on the anterior 

 edges of the fourth to seventh abdominal segments appears. Length, 26 mm. 



Last stage (76: 13, 20). Head (80: 5) dull dead black, bristling with short, black, 

 stiff hairs; mandibles piceous; other mouth parts and antennae black with the bases of 

 the joints pale. Body blackish purple with a velvety aspect or dark olivaceous maroon, 

 darkest in the middle of the segments; tubercles of the same color as the body except- 

 ing most of those of the supralateral series which are generally orange but with the 

 same short black hairs found on the dark tubercles ; the last pair of tubercles of this
