 larvae have twenty- two feet. The larva of Cimbex lucorum was not long 

 ago described and figured by SNELLEN VAN VOLLENHOVEN, Tijdschr.

Sub-genera : Abia LEACH, Perga LEACH, and others of this 

 author. Add sub-genus Pachylosticta KLUG, genus Syzygonia 

 ejusd. differing from all other cimbices in the cells of the wings, 

 but plainly resembling the Hylotomace (Brazilian species.) 



OKDEH VIII. Lepidoptera. 



Hexapod insects, with four membranous wings, covered with 

 ninute coloured scales. Mouth with involute spiral tongue, com- 

 posed of protracted maxillae. Metamorphosis complete. 



Butterflies (Lepidoptera L., from \67rk scale, and inepov, Glossata 

 FABR ) The two chief works on the anatomy of this order, that of 

 LYONET and of HEROLD, 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.
