496 GEOGRAPHICAL DISTRIBUTION OF INSECTS. 
Colliuris, Catascopus K.*, Apogonia K.°, a peculiar type of 
Horia, &c. In America, Agra, Galerita, Nilion, another 
type of Horia, Tetraonyz, Rutela, Doryphora, Alurnus, 
Erotylus, Scotinus K.°, Cupes, Corydalis, Labidus, Heli~ 
conia, Castnia, &c. And i in New Holland, Helluo, Ele- 
phastomus M°L.,: Anoplognathus, Agrostiphila M°L.*, 
Cerapterus, Heleus, Adelium K., Paropsis, Achilus K,, 
Thynnus, &c. 
The countries bordering upon the Mediterranean, the 
Black, and the Caspian seas, agree in producing similar 
insects. These countries, and the Cape of Good Hope 
though so distant from them, appear to be the principal 
seat of Heteromerous Coleoptera, of the genera Lixus and 
Brachycerus, and of the conical Buprestes*. But the in- 
sects of Guiana, on one side the Cordilleras, differ from 
those of New Granada and Peru on the other; and simi- 
lar differences are observed in other neighbouring coun- 
tries separated by naturaf boundaries. 
ili, Another head connected with the topographical 
distribution of insects relates to their representation ot 
each other. Here we may observe, that some insects re- 
present each other only in their form; others also in their 
Junction ; and others in both. I shall give some instances 
of each. In Brazil there is a group of petalocerous 
beetles (Chasmodia M‘L.), one of the Rutelide, which in 
New Holland has a representative, as to,form, in one of 
the Cetoniade (Schizorhina K.‘), which, having soft
