CANAEIAN COLEOPTERA. 



are even still less evidently striatc-punctatc (the minute punctules 

 being scarcely at all longitudinally disposed) ; its frontal tubercles 

 are perhaps somewhat more develoi^ed ; and its prothorax (which has 

 a less perceptible tendency to be narrowed behind) has its two inner 

 sulci less parallel, or more divergent on the posterior disc. 



The A. siihicoUe seems to be exceedingly rare, and confined to the 

 rotten bark of old pine-trees in the Finals of intermediate and rather 

 lofty elevations ; under which circumstances I have taken it at the 

 Agua Mansa in Tencriffe, and in the Barranco above S'"* Cruz in Palma,

The European A. hnmneus (which occurs, in certain spots, around 

 Funchal, in Madeira) is unquestionably universal in these islands, — 

 though hitherto it does not happen to have been observed in Grand 

 Canaiy. But in Lanzarote, Fuerteventura, (at the Banda of) Palma, 

 and (to the westward of Valverde in) Hierro, I have met with it 

 more or less abundantly, and it ■fl'as found by Dr. Crotch in Teneriffe 

 and Gomera. In the fii'st two of those islands it occasionally teems 

 beneath the refuse at the base of corn-stacks (in company with the 

 Trogosita mauritanica, Silvanus surinamensis, Cryptopliagus dentatus 

 and ohesidus, Corticaria serrata, Tcnehrio obscurus, Anthims fioralis, 

 &c.), where it has all the appearance of being an introduced insect.
