58 MODERN CLASSIFICATION OF INSECTS. 
from Waterhouse, fig. 66. 15. female pupa, fig. 66. 16. extremity of its 
abdomen sideways). Linnzeus was acquainted with the pupa, which he 
thus describes : ““Pupa currit, matri simillima, licet aptera. Caput ob- 
cordatum.” (Syst. Nat., tom. ii. p. 916.) Percheron denies that the 
pupa possesses this active power, and asserts that the entire body of 
the pupa merely “jouit de la méme faculté de contorsion et de sauts, 
que la larve exécute & un si haut degré.” Mr. Waterhouse has (quite 
correctly as it appears to me from analogy with some other quiescent 
pup, as Myrmeleon, &c.) reconciled these statements by observing 
that the pupa in some respects approaches the active pup, although 
it cannot be strictly considered as such until immediately before as- 
suming the imago state, when the insect having gained sufficient 
strength, is enabled to walk, although inclosed within the pupa skin, 
which, by the bye, is extremely thin. A peculiarity existing in this 
pupa, which has not been alluded to by previous writers, clearly 
proves it to be inactive in the early stage of the pupa state, namely, 
that the hind legs are partially covered by the wings. (Compare jig 66. 
15. with fig. 41. 11. p. 336., or fig. 48.19. p. 387.) The species are very 
few in number, and I am not aware that any have been discovered out 
of Europe. 
The family MAnTIspipz* Westw., like the preceding, consists of a 
single anomalous genus, whose situation has greatly perplexed sys- 
tematists, none of whom, however, appear to have given themselves the 
trouble of investigating the structure of its mouth.+ As already noticed, 
in vol. i. p. 412. note, it is without hesitation that regard this genus as

+ Imust now omit my friend Erichson, who (in his admirable monograph in 
Dr. Germar’s Zeitschrift fiir die Entomologie, No. 1. 1839, just received by me from 
the author) has investigated the affinities of the genus, and arrived at the same 
conclusion as myself. THe describes twenty-four species chiefly from Africa and 
America, but T am acquainted with several others yet undescribed.
