1072. Arthrodes byrrhoides. 



Arthrodes byrrhoides, Woll., Cat. Can. Col. 441 (1864). 

 Habitat Canarienses (Fuert.}, adhuc parce deprehensus. 



Two examples, taken by myself in Fuerteventura of the Canarian 

 Group, are all that I have yet seen of this Arthrodes. In general 

 sculpture, contour, and immarginate prothorax it has much in 

 common with the injlatus ; but it appears to be smaller, and to have 

 a short humeral plica well developed. 



1073. Arthrodes laticollis. 



Erodius laticollis, Brulle, in Webb et Berth. (Col} 63 (1838). 

 Arthrodes laticollis, Woll, Cat. Can. Col 441 (1864). 



Habitat Canarienses (Fuert.\ sub lapidibus rarior. 



Pound sparingly in Fuerteventura of the Canarian Group, whence 

 Messrs. Webb and Berthelot's types, as would appear by a label still 

 attached to them (for I need scarcely add that M. Brulle does not 

 allude to the habitat), seem to have come. I captured a few examples 

 of it either in the same island or else on the small adjacent rock of 

 Lobos (unfortunately I cannot now exactly recall which of them) ; 

 but since I invariably cite the latter as a portion of Fuerteventura, 

 in like manner as I regard Graciosa as pertaining to Lanzarote, it is 

 of but slight consequence whether they were taken on the main- 

 land or not.

1074. Arthrodes Hartungii. 



Erodius obesus? Hart, [nee r.~],Geolog. Verhaltn. Lanz.und Fuert.\l. 

 Arthrodes Hartungii, Woll, Cat. Can. Col. 442 (1864). 



Habitat Canarienses (Fuert.), a Dom. Hartung repertus. 



The only example of this large Arthrodes which I have yet seen 

 is from the collection of M. Hartung, by whom it was taken in 

 Fuerteventura ; and further material therefore is desirable, in order 

 to complete our knowledge of the species of which it would appear 

 to be the representative. 



consequent on the humeral costa being still less developed, and nearly obsolete. 

 I would record briefly the state of which they are the exponents, as follows : var. 

 y. crassa [an species?]. Sensim profundius punctata ; elytris ad humeros paulo 

 magis rotundatis, plica humerali etiam breviore (fere obsoleta). Habitat Canariam 

 Grandem, in inferioribus capta.
