hairs are segregated into definite patches. There is a large patch on 

 the front, a smaller patch on either side behind and outside of this, 

 just within the anterior portion of the base of the antennae, a large 

 patch on the sculptured portion of the eye, a smaller patch beyond this 

 and separated from it by the glazed eye, and a small but conspicuous 

 patch on either side of the labrum. 



There are no hairs on the wing covers or elsewhere on the ventral 

 surface, except as follows. The first abdominal segment beyond the 

 wing covers ventrally bears on either side of the median line a row of 

 three hairs, the outermost the longest, at some distance beyond this a 

 single hair, almost as far again beyond this single hair a group of 

 three hairs arranged in a triangle, and beyond these seven widely 

 scattered hairs. The next segment has the hairs similarly arranged. 

 The segment following has the innermost group reduced to two hairs, 

 and three hairs arranged in an equilateral triangle in place of the 

 single hair on the segments preceding. The next segment has one 

 hair anteriorly and near the median line, another slightly behind and 

 outside this, two more beneath the middle of the space between the 

 inner two hairs and the group of three on the preceding segment, and 

 several more near the outer border. The segment preceding the 

 cremaster has two hairs, one in front of the other, beneath the two 

 innermost hairs on the preceding segment, and several more hairs in 

 the outer portion of the posterior half. 



The cremaster is provided with numerous long, stout hooks with the 

 tips recurved spirally so that the point is on one side of and some 

 distance from the shaft. 



Eight pupae give the following dimensions : 



These measurements were made from pupae formed by caterpillars 

 in captivity. As the caterpillars were not fed it is possible that the 

 pupae are slightly below the average size. However, normal-sized 

 butterflies emerged from others of the same lot.
