TROGID^E. 181 



residing for the most part on or near the sea-beaches, where it 

 burrows beneath various rejectamenta and at the roots of sand-plants. 

 In such situations I have taken it abundantly in the eastern parts 

 both of the Madeiran and Canarian Groups namely, in Porto Santo 

 of the former, and in Lanzarote and Fuerteventura of the latter.

Trox hispidus ?, Brulle [nee Fab.~], in Webb et Berth. (Col} 60 (1838). 

 conttuens, Woll, Cat. Can. Col. 193 (1864). 



Habitat Canarienses (Ten.}, rarissimus. Sub lapide juxta urbem 

 Sanctae Crucis exemplar unicum collegi. 



A single specimen of this Trox was captured by myself at a low 

 elevation in Teneriife beneath a stone, in the Barraneo do Passo 

 Alto, near S ta Cruz ; but it is the only one that I have yet seen.

Silpha scabra, Linn., Syst. Nat. i. ii. 573 (1767).

Habitat Maderenses (Mad.}, circa domos parce occurrens ; forsan ex 

 Europa introductus. 



The European T. scaber occurs very sparingly in and about houses 

 in Madeira proper, where in all probability it has become naturalized 

 from higher latitudes. It has been taken by the late Dr. Heineken, 

 as well as by Messrs. Bewicke, Park, and F. A. Anderson.
