Longicornia Malayana.

The second section, containing those species with the 

 eyes finely granulate, includes the great bulk of the 

 Cerambycidce, which are placed in M. Lacordaire's 

 arrangement in three divisions : the first two and the 

 last depend for their difi'erentiation on the point of inser- 

 tion of the antennae, and the second, which contains 

 no Malayan species, scarcely merits — according to our 

 author — separation from the first. The number of sub- 

 families in this section, which includes the remainder of 

 the Cerambycidce, represented in Mr, Wallace's collection, 

 amounts to sixteen, out of the fifty -four " groupes " into 

 which M. Lacordaire divides it. The following table 

 exhibits the principal characters on which the subfamilies 

 are based.
