CANAKIAN COLEOPTERA. 



is, if anything, shorter, and more equally rounded at the sides (where 

 it is somewhat less broadlj- flattened), and has the anterior angles 

 aciiter. It appears to be rather scarce in Lanzarote and Fuerteven- 

 tura (in the former of which it was found likewise by Mr. Gray and 

 M. Hartung), but more abundant in Grand Canary (particularly in the 

 sandy districts near Las Palmas and Maspalomas — in the north and 

 south, respectively), and locally common in Teneriffe (whence it 

 has also been communicated by the Barao do CasteUo de Paiva and 

 Dr. Crotch). It is found in the Madeiran Group, — a recent, and more 

 accurate, comparison of my 0. errans with types of the /ifscwm having 

 convinced me that the two are conspecific*.

I have already stated that I erroneously regarded this Opatrum, in 

 my ' Ins. Mad.,' as the fuscimi (or rusticum) of southern Europe ; 

 which led me into the additional mistake of describing the latter as 

 a new species (under the name of errans). It is, really, the hispidum 

 of Brulle, and (according to M. Deyrolle) may perhaps be identical 

 with the affine of Billberg ; in which case the latter title would have 

 the priority. That it is Erichson's pro^t.i'M«i (cited as Angolan, but 

 in reality from the Cape de Verdes f) I can state for certain, having 

 received two original types (a S and $ ) of that species from Schaum. 

 It is a common insect throughout the whole of these Atlantic Groups, 

 aboimding at the Madeiras and the Cape de Verdes. At the Canaries 

 it is universal, I having myself captured it in the whole seven islands, 

 more or less profusely. In Gomera it was found also by Mr. Gray 



* In my ' Ins. Mad.' I applied the name of fuscum to the wrong insect — 

 namely, to the hispidum, Brulle ; and so fell into the error of regarding the true 

 fuscum as a new species.
