An elaborate description of the development of the facetted 
eyes of the perfect Beetle in the larva of Tenebrio molitor. 
In his / Coleoptera Hesperidum,^ devoted to the Coleopterous 
insects of the Cape Verde group of islands, Wollaston embodies 
the results of his own investigations and of those of John Gray, 
P. W. Hutton, A. Pry, and II. Dolirn. Of the nine larger 
islands composing the Cape Verde archipelago, only six have 
been examined for Coleoptera, the three others, situated nearest 
to the African coast, not having been visited by the author or 
his friends. These are known as the “ Salt Islands and 
although it is probable they will present some interesting pecu- 
liarities, their investigation could hardly lead to any change in 
the general results at which Wollaston has arrived. The total 
number of species ascertained by Wollaston is 278, distributed 
as follows in the primary groups adopted by him : — 
Heteromera . 
Brachelytra . 
Necrophaga , 
Geodephaga , 
Bhynchophora 
Priocerata . 
Cordylocerata 
Phytophaga . 
Pseudotrimera 
Philhydrida

Thus the numerical proportions of the groups are in general 
nearly the same as in the more northern groups of islands, 
except that the Heteromera and Bhynchophora have changed 
places — a circumstance which the author regards as in accord- 
ance with the nature of the species of these groups, the Hete- 
romera being better suited than the Bhynchophora for the 
present condition, at all events, of the arid Cape Verde islands. 
The number of species ascertained to exist in each island is 
stated by the author as follows : —
