1318 THE BUTTERFLIES OF NEW ENGLAND. 



rior half, broadest at the third thoracic segment, the posterior half nearly equal. Very 

 dnrk olive brown, tlie first thoracic segment with a transverse, dull orange spot in the 

 middle of the dorsum, the tliird thoracic segment with a rather large, lateral, oljliquely 

 oval, velvety blaclv spot, bordered above and below with yellow, a lateral white band 

 on the lower portion of tlie second and third thoracic and first and sec(nid al)domhial 

 segments, curving upward to the upper portion of tlie sides on the third and sending a 

 small line backward upon tlie fourth abdominal segment; eiglith abdominal segment 

 white, with two subdorsal yellowish browu spots placed posteriorly ; on the first 

 and fourth to sixth abdominal segments a pair of minute, bluish white, subdorsal 

 spots ; the first and second thoracic and ninth abdominal segments with a pair of short, 

 thick, cylindrical, fleshy, infuscated, lateral tubercles, furnished with short black 

 hairs, those of the ninth segment much the longest ; a similar but not infuscated supra- 

 lateral pair on the eighth abdominal segment; a subdorsal row of small warts on 

 all the segments, but conspicuous only on the eighth abdominal, whicli also Ijears a 

 smaller, secondary pair within and in advance of the others. Length, 9 mm. ; breadth 

 of head, 1 mm. ; greatest breadth of body, 2.5 ram. ; posteriorly, 1.75 mm. 



Third stage (76 : 19, 22). Head (79 : 71) pale greenish with an orange tinge, covered 

 with very delicate, very short hairs; ocelli black in a pale fuscous field; moutli parts 

 pale yellowish. Body above, blackish, sometimes olivaceous brown, mottled with glis- 

 tening black, below pale bluish green; a straight white band runs from the spiracle 

 of the first thoracic to a large laterodorsal white spot on the third abdominal segment, 

 sometimes interrupted or oliscured with blackish brown on the second abdominal seg- 

 ment ; the eighth alidominal segment white, with a triangular, dorsal, anterior patch of 

 the color of the rest of the body; tip of body white; on the first and fourth to seventh 

 abdominal segments a laterodorsal row of small, longitudinally oval, pale blue spots; 

 on the third thoracic segment a large, slightly elevated, shining piceous, lateral wart, 

 centrally placed, and in front of it a velvety black spot of equal size, the whole edged 

 with yellow; a subdorsal series of small, shining, yellowish brown warts on the third 

 thoracic and first and second abdominal segments ; on the third thoracic a pair of simi- 

 lar ones jnst above the larger lateral one, and on the first abdominal another similar 

 pair just below the laterodorsal blue spot; first thoracic segment witli a pair of lateral 

 ■warts which are brownish yellow at tip ; eightli abdominal segment with a pair of lat- 

 erodorsal yellowish tubercles and the ninth with a pair of latei'al, elongated, lirownish 

 yellow tubercles furnished with frequent, short, straight hairs. Osmaterium pale 

 orange. Body covered ^vith very short and very delicate hairs. Legs of the color of 

 under surface, the claws blackish; ventral prolegs pale greenish brown; anal prolegs 

 ■white. Length, 15 mm. ; breadth anteriorly, 4.25 mm. ; breadth posteriorly, 2.5 mm. ; 

 breadth of head, 1.8 mm. 



Fourth stage. Head (79 : 72) uniform pale green, the ocelli brownish fuscous pointSi 

 the two anterior darker than the others ; mouth parts and other appendages pale green, 

 infuscated toward tip. Body, above, varying from blackish brown to rather pale oliva- 

 ceous brown, bluish white beneath and on lower edge of sides to just above the 

 stigmatal line. This is slightly whiter above the stigmatal line, forming a white supra- 

 stigmatal band which runs up a little higher on the first thoracic segment, sends abroad, 

 oblique shaft upward and backward to the laterodorsal line on the second and third 

 abdominal segments, and across the eighth abdominal segment except for a small 

 median spot ; the suprastigmatal white band also encircles the tip of the body. The 

 oblique tlirust of the suprastigmatal band is to give eflect to the great hunch of the 

 anterior part of the body when at rest, as it partly encircles its posterior margin. The 

 dark upper part of the body is, however, much enlivened by other markings : generally 

 the fourth and fiftli abdominal segments and especially the dorsal parts within the 

 laterodorsal lines, sometimes the whole of the abdomiual region behind the hunch is 

 of a slightly lighter tone than the rest ; the same is sometimes the case with the top of 

 the hunch, especially laterally within the velvety patch ; and the whole of the dorsum 

 of the first and second thoracic segments behind the anterior, pale orange, osmaterial 

 ridge is always as dark as any other part and generally is rather darker. Besides
