246 STATES OF INSECTS. 



verse stride, formed of very minute granula, the lower side 

 being transversely sulcared. In some few instances, as 

 in Arctia Salic is, Laria pudibunda and Jascelina, the skin 

 of the pupa is clothed with hair a : as is also that of He- 

 speria Bixce, according to Madame Merian b . De Geer 

 has described a little beetle under the name of Tenebrio 

 lardarius (Lairidius Latr., Corticaria Marsh.), the pupa 

 of which is beset with very fine hairs, terminating in 

 a spherical or oval button c . 



ii. I shall include under the same head both the ^figure 

 or shape, and parts of pupae, as the latter in most kinds 

 are either the same or nearly the same as those of the 

 larva, or merely incasing those of the imago, so as not to 

 require that detailed notice that I judged necessary when 

 treating of the parts of larvae. 



With regard to incomplete pupae, nothing further can 

 be said of their extremely vaviousjigure, than that it has 

 a general resemblance to that of the perfect insect. The 

 head, trunk, abdomen, and their respective external or- 

 gans, are alike visible in both; but in the pupae, the latter, 

 instead of occupying their natural situation, are all closely 

 folded under the breast and abdomen : or, as in the case 

 of the long ovipositors of some Ichneumons, laid along the 

 back. In a specimen of some coleopterous insect now 

 before me, the following is the order of the arrangement 

 of the parts:— The head is inflexed; the mandibulae are 

 open ; between them are seen the labium and labial palpi; 

 these appear to cover and conceal the maxillae, and the 

 maxillary palpi extend on each side beyond them ; the
