affinities. We consider the types, however^ to be per- 

 fectly distinct from, although strongly resembling in 

 outward appearance, the Silphidce or PimelidcB (the cor- 

 responding group in the tribe of Predatores) ; and that 

 the StenochicB enter herein. Finally comes the genus 

 Hispa, as the type of a family^ alike distinguished in 

 its larva and its perfect state. By this form, and 

 Alurnus, we again reach the CassidcB, and complete the 

 circle of the Monilicornes which are here epitomised.

Every principle of analogy drawn from various groups 

 of vertebrate animals, no less than of insects, shows that 

 Cassida is the pre-eminent type of the whole tribe; and 

 we have seen that such is also the station of the lamelli- 

 corn beetles. Coccinella, in fact, although raptorial in 

 its larva, is but a sub-family of the Cassidce; and this 

 station, confirmed by analysis, shows it to be the raptorial 

 division. In what manner the Chrysonielidce represent 

 the Predatores, otherwise than in holding the second sta- 

 tion in its own circle, does not appear; but the soft elytra 

 of the ClythridoB seem to represent the Malacodermes. 

 The resemblance, again, of such genera as Erotylus 

 and Stenochia to Blaps and many of the Silphidee, is 

 so close, that it is difficult to distinguish one from the 

 other ; while the larva of Hispa is stated to be so like 

 that of the capricorns, that we cannot be very far wrong 

 in assimilating them: nevertheless, until the true station 

 of Sngra and Donacia have been worked out, we look 

 upon the station here assigned to Hispa as more than
