An insect which occurs, though very rarely, both in the Madeiran 

 and Canarian Groups. I have taken it on the southern Deserta (or 

 Bugio) of the former, and in Lanzarote, Fuerteventura, and Teneriffc 

 of the latter. Although perfectly distinct from the European T. 

 scrobiculatus, it is a good deal allied to that species.

The common European T. riparius occurs, in damp places of low 

 and intermediate altitudes, both in the Madeiras and Canaries. 

 In Madeira proper I have met with it sparingly around Eunchal; 

 and in my Madeiran Catalogue I cited it, though as it would now 

 appear erroneously, as the bilineatus*. Throughout the Canaries it 

 is more widely distributed having been taken by myself in Grand 

 Canary, Teneriffe, and Palma, and by the Messrs. Crotch in Teneriife 



1431. Trogophlceus oculatus.

* Although there is not the slightest doubt that the Madeiran Trogophlceus is 

 identical with the Canarian one, and that the latter is positively the riparius (as 

 understood by that name in England), I nevertheless must add that a specimen 

 from Madeira was identified by Dr. Kraatz with the " bilineahis" and not with 

 the riparius. I feel pretty sure however that Kraatz must have given me his 

 opinion hastily, and without any very accurate examination ; for the diagnoses of 

 the two species in question leave no doubt on my mind that the Madeiran and 

 Canarian one is truly referable to the riparius ; and such, I may add, is the 

 opinion both of Mr. Rye and Mr. Waterhouse who have taken great pains in 

 comparing these Trogophlcei for me with British types.
