TIIK snnWMILY LKMONIINAE. 779 



Two species of Ilelicopis, eiulyiiiion ami ciipido, arc figured by Stoll', 

 and resemble each otliei" considerably. The caterpillar of cndymion is 

 represented as having a head covered with a dense red pile, besides long 

 white hairs, the red pile giving it. in the rather coarse illustration, a size 

 apparently nuicii greatei- than reality ; that is, of about the same breadth 

 as the body, and larger tlian the segment next succeeding; if tliis is 

 accurately represented, it would be very different from other Lemoniinae ; 

 but the similar character of the anterior exti-emity of the chrysalis, which 

 can hardly be thought to be other tiian tapering at this point, leads us 

 to believe that in iioth tlie i-epresentation of the pile obscures the actual 

 outline of the liard parts. The body of the caterpillar is apparently nearly 

 cylindrical, but depressed. feel)ly fusiform, and a little more than three 

 times as long as bi-oad. with frequent long white hairs as long as the body. 

 The chrysalis is again of a siuiilar shape and longer in proportion to its 

 width than any other chrysalis of the Lemoniinae, being not greatly less 

 than four times as long as broad. It is nearly uniform, but tapers con- 

 siderably toward the tail, where it shows no sign of being constructed 

 otherwise than in otiier Lemoniinae. The body is covered with long white 

 hairs, as in the caterpillar, together with the red pile already referred to 

 at the anterior extremity, which is again repeated at the tail. The chrys- 

 alis is represented as lying upon the top of a leaf, fully exposed. 



The caterpillar of H. cupido is very similar to the last, but the head is rep- 

 resented as itself red without the pile of the other species and yet is nearly 

 as large as that, being indeed narrower than tlie body but bi-oader than 

 the segments immediately posterior to it. It should be remarked, how- 

 ever, that the head of the cast-off skin at pupation is not at all larger than 

 the front segment of the caterpillar : now as tliis is seen in full face, we 

 must believe that it represents more correctly the actual relation of tlie 

 head to the body. The body, covered with the same kind of pile as the 

 other species, does not differ from it sufficiently to call for comment, 

 excepting that it is longer and slenderer and more uniform, being about 

 four times as long as broad. The chrysalis differs considerably from that 

 of endyraion, being represented with the ordinary form of a noctuid moth, 

 largest in the middle, bluntly rounded in front, tapering to a point pos- 

 teriorly and about three and a half times longer than broad. In this in- 

 stance it is represented from the ventral side, as is seen by the attemjit to 

 indicate the position of the legs ; this has doubtless been done in order to 

 show that in the chrysalis as in the caterpillar the head is red, the head 

 being entirely upon the ventral surfece, a point which could not be 

 shown had the chrysalis been placed in the opposite position ; the net work 

 of pale lines which are seen at the edge is simply meant to represent the 

 long pale hairs characteristic of this genus both in the larva and chrysalis 

 state. The position of the cast-off skin with the rude painting of the leaf
