Shield-winged (Coleoptera from xoreos, sheath, covering, shield, and 
mtepov, wing), with Fabricius Hleutherata. We have on this 
numerous order of insects amongst others the following works :— 
J. E. Vort, Catalogus systematicus Coleopterorum, Hag. Com. 
1769—1806, 4to, 11 parts. With (1st part 55, 2d part 50) beautifully 
coloured plates ; those of the first part-mostly engraved by KLEEMANN 
and some by Rasen, and a very useless Latin, French, and Dutch 
text. G. W. F. Panzmr has supplied a german edition of it with 
the addition of the synonymy. Erlangen, 1793—1798. 
A. G. Outvisr, Entomologie, ou Hist. Natur. des Insectes (Coleop- 
teres.) Paris, 1789—1808, vir Tomes, 4to, ay. (363) pl. enluminées. 
(The plates make up the last two parts). Srurm has given a less 
costly edition of the plates, but not complete. Nirnberg. 1802, 
1803 (96 plates). Itiicer undertook a German edition of the 
text.

For the anatomy the above-cited Monograph on the Cockchafer 
by Straus DurckHEem may be consulted (see above, p. 256), and 
also the numerous investigations of Lron Durour, which extend 
over the whole of this order. Ann. des Sc. natur. Tom. 1, m1. 1824,

This order is distinguished from the preceding by the complete 
metamorphosis, as also by the absence of a galea, howsoever in some 
two pairs of maxillary palps are present, and morphologically the 
innermost palps do not differ from the galea of the Orthoptera.
