and Saperda) ; and the second, having rounded eyes, being solely 

 composed of the family Lepturidae. M. Serville, on the other hand, 

 has four groups of equal rank ; Prionii, Cerambycini, Lamiariic, and 

 Leptureta}. That the Lamiaria3 constitute a distinct group, will not 

 be doubted ; but the characters which separate them from the other 

 Cerambycidae, namely, the vertical direction of the head, and the 

 truncation of the palpi, can scarcely be deemed of sufficient value to 

 raise them to the rank of a distinct family, equivalent to the Prionida; 

 and Lepturida?. Moreover, the general appearance, colours, and 

 habits of the insects appear to warrant the establishment of only three 

 families ; the Prionidae being bj'^ far the largest insects in the sub- 

 section, of obscure colours, with large exserted jaws, and antenna; of 

 moderate length : the Cerambycidae are of moderate size, and gaily 

 ornamented, with longer antennae ; whilst the Lepturidae are generally 

 of smaller size, the antennae but of moderate length, and the habits 

 more diurnal than the preceding. Mr. Stephens has, indeed, intro- 

 duced the Cucujidae into this subsection ; a step which most certainly 

 violates nature. 



The first of the three families of which the subsection is composed 

 is the PRioNiDiE* Leach, comprising some of the largest known insects
