larvee have twenty-two feet. The larva of Cimbex lucorwm was not long 
ago described and figured by SNELLEN VAN VOLLENHOVEN, Tijdschr. 
voor nat. Gesch. 1. 1843. Tab. I. 
Sub-genera: Abia Leacu, Perga Lracu, and others of this 
author. Add sub-genus Pachylosticta Kuve, genus Syzygonia 
ejusd. differing from all other cimbices in the cells of the wings, 
but plainly resembling the Zylotomae (Brazilian species.) 
-Orver VIII. Lepidoptera. 
Hexapod insects, with four membranous wings, covered with 
minute coloured scales. Mouth with involute spiral tongue, com- 
posed of protracted maxilla. Metamorphosis complete. 
Butterflies (Lepidoptera L., from ders scale, and mrepov, Glossata 
Fasr.) The two chief works on the anatomy of this order, that of 
Lyoner and of Herotp, have been already cited (see above, pp. 247 
and 275). To give a list approaching to completeness of the works 
which treat of the arrangement of butterflies, or illustrate their 
species by figures, would require too much space for our purpose. 
We satisfy ourselves therefore with indicating some of the prin- 
cipal sources for the knowledge of this order.
