CANAKIAN COLEOPTERA. 519 



its head and prothorax (the latter of which is rufo-ferruginous and 

 less widened anteriorly) are much less coarsely and less closely punc- 

 tured ; its elytra have their basal fascia larger and differently shaped, 

 and increased by an additional patch (rarely obsolete), common to 

 them both, on the suture behind ; and its surface is free from the 

 elongate, erect, darker hairs which are so conspicuous in that insect. 

 As at Madeira, it appears to be rare in these islands, though widely 

 distributed over the archipelago. I have taken it sparingly at San 

 Mateo in Grand Canary, and near the Puerto Orotava in Teneriffe ; 

 and it was found by Dr. Crotch in Gomera. It is recorded by La 

 Ferte from Egypt and Senegal.

A. colore facieque generali A. crinito prima facie fere similis, sed pube 

 breviore minutiore ac magis demissa irroratus ; capite prothoraceque 

 sensim minoribus, minus nitidis ac multo densius punctatis, illo 

 ovali (ergo postice rotundatiore, angulis posticis omnino rotundatis 

 obsoletis) rufescentiore oculis minoribus, hoc postice magis con- 

 stricto ; elytris subconvexioribus (ad latera vix magis rotundatis)

 bipartita (i. e. in maculas duas divisa). — Long. corp. lin. 1^1^.

The A. humilis of central and southern Europe may easily be known 

 from the crinitus (to which in its general colouring the brighter ex- 

 amples of it approach very closely) by having its pubescence shorter, 

 minuter, and completely decumbent ; both its head and prothorax 

 smaller, rather less shining, and much more densely punctured — the 

 former being likewise more oval (or rounded behind the eyes — which 

 are themselves less developed) and more rufescent, whilst the latter 

 is more constricted posteriorly ; and by its elytra being just percep- 

 tibly convexer and more rounded at the sides, less evidently impressed 

 behind the base, rather more lightly punctured, and with their post- 

 medial patch (or abbreviated fascia) both larger and more decidedly 

 interrupted (or divided into two spots) along the suture, I have seen 

 hitherto but six examples of it, all of which were captured (five of 

 them by myself, and one by Mr. Gray) in Lanzarote — I believe, at the 

 Salinas, in the extreme north of that island.
