CANAMAN COLEOPTERA. 241 



pearance, primd facie, of the two following Sp7i(enci, and of the S. 

 albopictiis from the Madeiran Group, Hitherto I have myself ob- 

 served it only in Teneriffe ; but it was taken rather commonly, by 

 Dr. Crotch, near Hermigua in Gomera. In the rocky ground above 

 the Puerto of Orotava, in Teneriffe, I have brushed it, abundantly, 

 from off the dead plants of a large Tanacetum ; and I have likewise 

 met with it in a small Barranco near Souzal, as well as at Taganana. 

 Like the JSphcerici it is excessively variable in stature, descending to 

 a most diminutive bulk.

The distmctions between the present insect and the Madeiran S. 

 albopictus, which at first sight it closely resembles (its almost undi- 

 lated penultimate tarsal joint being the most important of them), 

 have been fuUy pointed out in my Paper on the Canarian Ptinidce. 

 The few specimens of the S. simplex which I have myself taken were 

 captured near Valverde, in the island of Hierro, during February 

 1858 ; but I have lately examined an individual which was found by 

 Dr. Crotch in Gomera. 



385. Sphaericus gibbicollis. 



Sphaericus gibbicollis, Woll., Trans. Ent. Soc. Lond. (3rd series) i. 208 

 (1862). 



Hahitat in Lanzarota et Fuerteventura, rarissimus. 



Foiir specimens only of this distinct Sphcericus (which may be 

 known, inter alia, by its anteriorly-gibbous prothorax) have as yet 

 come beneath my notice. Two of them I captui'ed at Ye, in the ex- 

 treme north of Lanzarote, during March 1859 ; and the other two I 

 beat out of an old bush of the Common Rosemary {Rosmarinus offi- 

 cinalis) at Agua Bueyes, in Fuerteventura, on the 28th of January of 

 the preceding year.
