CANARIAN COLEOPTERA. 15 



Genus 11. BLECHRUS. 



Motschulsky, Bull, de Mosc. iii. 219 (1847). 



22. Blechrus glabratus. 



Lebia glabrata {Meg.) Diifts., Fna Austr. ii. 248 (1812). 

 Dromius glabratus, Brulli, in Webb et Berth. (Col.) 55 (1838). 



negrita, Woll, Lis. Mad. 9 (1854). 



glabratus, Id., Cat. Mad. Col. 4 (1857). 



Blecbrus glabratus, Schaum, Nat. dei' Ins. Deictsch. i. 275 (1860). 



Habitat Teneriifam, rarior ; in sylvis ad Agua Garcia et Taganana 

 captus. 



Amongst the few specimens of the B. maurus which I have taken 

 at the Canaries, I find one which must certainly be referred to the 

 nearly allied species glabratus. It was captured in Teneriffe, — at 

 the Agua Garcia. 



23. Blechrus maurus. 



Dromius maurus, Sturm, Deutsch. Fna, vii. 55. t. 171. f. D (1827). 



glabratus, Wall., Ins. Mad. 9 (1854). 



maurus. Id., Cat. Mad. Col. 5 (1857). 



Blechrus maurus, Schaum, Nat. der Ins. Deutsch. i. 276 (1860). 



Habitat in Canaria, Teneriffa et Palma, sub lapidibus, passim. 



The common European B. maurus, although rather abundant at 

 Madeira, appears to be somewhat rare, or at all events very local, in 

 these islands. I have taken it in Grand Canary ; at Laguna, the 

 Agua Garcia, Souzal, and Orotava, in Teneriffe ; and in Palma ; and 

 it was captured in Teneriffe by Dr. Crotch. 



24. Blechrus plagiatus. 



Lebia plagiata {Meg.), Dufts., Fna Austr. ii. 249 (1812). 

 Dromius plagiatus, Sturm, Deutsch. Fna, vii. 49. t. 170. f. D (1827). 



, Woll, Cut. Mad. Col. 5 (1857). 



Blechrus plagiatus, Schaum, Nat. der Ins. Deutsch. i. 277 (1860). 



Habitat in Lanzarota, Fuerteventura, Canaria, Teneriffa et Gomera, 

 hinc inde baud infrequens. 



The B. plagiatus (which is of the greatest rarity in the Madeiran 

 Group) would seem to be more common at the Canaries than the 

 preceding species : nevertheless it is undoubtedly scarce, though very 

 widely distributed over the archipelago. I have taken it in Lanza- 

 rote, Fuerteventiu'a, (at San Mateo of) Grand Canary and (at Souzal 

 arid the Agua Garcia of) Teneriffe ; and it was captured by Dr. Crotch, 

 at Hermigua, in Gomera. All my specimens from Lanzarote (ten 

 in number) belong to a dark variety of the insect in which the tes- 

 taceous elytral dash is obsolete — or, at any rate, so completely suf-
