476 THE BUTTERFLIES OF NEW ENGLAND. 



and especially on the upper part of the body where pale markings have predominated. 

 Appendages consisting of conical Avarty processes (86 : 71) several times higher than 

 broad, seated on low inconspicuous mammnlae and terminated each by a straight aculi- 

 form spine nearly as large at base as the docked tip of the process, and of about the 

 same length ; the latter furnished just above the middle by a whorl of four (or more) 

 aculiform spines directed upward at right angles to each other, and seated on little 

 warty processes or projections, together about half as long as the main process ; mid- 

 way between these and the base is sometimes a similar whorl of spinules, more nearly 

 horizontal and seated on similar warts. 



Fourth stage. Coloration much the same as in the succeeding stage. As to the 

 appendages (86 : 72) , the process has become a stout tapering spine, many times higher 

 than broad, tipped by a straight needle half as long as itself and furnished near the 

 middle with a more or less irregular coronet of tapering spinules, fully as long as the 

 width of the main spine at the point, diverging at about right angles with each other 

 and surmounted by a needle nearly as long as the main apical one ; midway between 

 this coronet and the base is a secondary one similar to that found in the third stage. 

 Last stage (74 : 37). Head (78 : 63) blackish brown, very delicately scabrous, covered 

 with large and rather infrequent tubercles and numerous warts, being very long, white, 

 tapering hairs, the warts on which they are seated usually white, but occasion- 

 ally dull luteous, the latter occuring in a short streak which passes down the front 

 from the summit of either hemisphere, and also in a narrow streak curving around the 

 ocellar field and passing also upAvard ; a few black hairs are formed on the summit. 

 First joint of antennae dull luteous; second fuscous at base, beyond dull luteous; 

 third brownish yellow, the bristle pale; ocelli very dark reddish brown; labrum 

 blackish, edged with pale below ; mandibles blackish ; maxillary palpi brownish yellow , 

 the extremities of joints annulate with fuscous. 



The prevailing hue of the body is a pale, dingy, olivaceous yellow, brightening in places 

 so as to form broken longitudinal stripes, of which there is a nearly continuous 

 double dorsal one, divided by black, an almost entirely continuous one on the infra- 

 stigmatal fold, and on the anterior half of the segments, and a longitudinal dash in front 

 of the laterodorsal and laterostigmatal spines; otherAvise the body is very heavily 

 and irregularly mottled with velvety black, most distinct on the sides of the thoracic 

 and first two abdominal segments between the two rows of spines above the spiracles ; 

 and on the succeeding segments, to a less degree, in the same region, but only on the 

 anterior half of the segments and just above the yellowish patch already mentioned; 

 the anterior half of the first thoracic segment and the posterior half of the last 

 abdominal segment are fuscous above ; the body is profusely covered with minute 

 pale yellowish wartlets, from each of Avhich arises a long, curved, tapering, pellucid 

 hair, they being more conspicuous than in the other species ; spines (86 : 73) pellucid 

 or pale yellowish, the longest ones scarcely exceeding in length one half the extreme 

 width of the head, the apical spinule, or that portion of the main stem which lies 

 beyond the base of the lateral spinules, much larger than the other part of the spine, 

 the spines being but little elevated at their base ; the spinif orm tubercles of the first 

 thoracic segment are very short. The spine has become more or less irregularly coni- 

 cal, OAving to the infiuence of the spinules upon the main stem ; the apical needle is 

 scarcely one-fourth the length of the spine, the spinules in the upper coronet are 

 more than twice as long as the Avidth of the spine at their base and the needles tipping 

 them are of about the same length as the central one ; the subordinate series of spin- 

 ules have assumed the importance of the primary series of the previous stage, are 

 nearly as long as the Avidth of the spine at their base and are surmounted by needles 

 nearly double the length of those in the upper roAv. There are also at various points 

 on the spine, and particularly next its base, minute Avarts giving rise to delicate short 

 needles ; spiracles velvety black, bordered Avith pale yelloAV ; legs dark brownish yel- 

 low, their base and tlie loAver part of the segment between the base, fuscous, the 

 second joint blackish, especially toAvard either extremity, the claAvs black; prolegs 

 broAvnish yelloAv. Length of body, 30 mm. ; breadth of body, -i mm. ; length of 

 spines, 2 mm. ; breadth of head, 3 mm.
