442 CANARIAN COLEOPTERA. 



I have little hesitation in identifying three 8])ecimens now before 

 me (and which were captured by myself, either in Fuerteventura or 

 else in the little adjacent island of Lobos) with M. Brnlle's Erodius 

 hiticoUis ; for the notes which I took whilst in Paris, after an ac- 

 curate inspection of his ty^^es, are in almost precise accordance with 

 the Arthrodes now under consideration ; whilst the fact of his ex- 

 amples being labelled as coming from " Fuerteventura " would tend 

 still further to corroborate my conclusion. In the excessive short- 

 ness of its humeral plica the A. laticoUis (as here defined) agrees 

 with the hyrrlioides, but although thus abbreviated the plait is very 

 much thicker than in that species ; and yet, in spite of this, the ex- 

 treme base of the elytra does not surpass in width the base of the 

 prothorax — but rather the reverse, inasmuch as the hinder protho- 

 racic angles project perceptibly beyond the humeral ones. There is 

 also a peculiarity in that particular region, from the surfaces of the 

 elytra and prothorax not being, there, in a continuous curve,— both 

 of them somewhat /a ZZ«i(/ away, so as to produce a slight fissure, or 

 lacuna, at either end of the sutural line which separates the two seg- 

 ments. In other respects, the A. Jaticollis is remarkable for being- 

 shining, and for having its head and prothorax (the latter of which 

 is transverse and immarginate) most minutely and rather distantly 

 punctulated ; whilst the elytral granules are, in hke manner, exces- 

 sively diminutive and remote — indeed but just distinguishable even 

 beneath a high magnifying power. Its frontal carina is considerably 

 raised, and rather angulated in the centre.

Although very unwilling to erect a species, in a genus like the 

 present one, from the evddence afforded by a single example, yet a 

 large Arthrodes now before me (which was taken by M. Hartung in 

 Fuerteventura) differs so widely in its sculpture from the A. puncta- 

 talus that 1 cannot believe it to be referable to any state of that in- 

 sect. It (Ufters mainlj- in the punctules of its entire surface being
