guished by the very great dilatation of the elytra posteriorlyj 

 giving to these Insects the general appearance of the genus 

 Lyciis^ many of the species of which they also imitate in the 

 disposition of their colours. In addition to the genera above 

 noticed, this century embraces insects referable to the following 

 types : Trachys^ Rhipkera, Chelonarium^ ParnuSy Lucatius, 

 Attelahus, Prionus, Ctetwdcs^ (intermediate between Prioniis 

 and Trachj/dcres,) Trachi/dcres^ Ccrambjjx, Calliclti-ovia, Luniufj 

 MularchuSy and Stcnoptcrus. Of the accuracy of the descriptions 

 the name of Professor Klug affords a sufficient guarantee. The 

 Paper is illustrated by coloured engravings of sixty of the Insects 

 described in it. 



The " Insecta Coleoptrata, quae in itineribus suis, praesertim 

 alpinis, collegerunt, Dr. D. D. Iloppe and Dr. F. Hornschuch,"

 Species by Sturm and Ilagenbach. They are referred io the

 species. Figures of the whole of them, with the exception of 

 the Carabus Hoppei^ are given from the excellent and esteemed 

 pencil of Sturm.
