230 Mr. T. Vernon Wollaston on 
(Sp. 275) Acrotrichis anthracina. 
This Acrotrichis, which was enunciated by Mr. Matthews 
in 1865 from the Canarian material of the Messrs. Crotch, 
is stated by the former to have since been captured by 
himself in England (namely, during the summer of 1867, 
in Sherwood Forest) ,—so that the species, ike so many 
others in this family, is a European one. Speaking of 
his British examples, Mr. Matthews says (Hnt. Month. 
Mag. v. 10; 1868) ‘*'The anthracina is a distinct and 
well-marked species; it belongs to the first division of 
the genus, which comprises the atomaria, and others, 
whose thorax is much dilated at the base, with its poste- 
rior angles produced beyond the shoulders of the elytra ; 
but from all these it may easily be known by its small 
size, and short black antennz ;”’ and as he then charac- 
terizes it afresh, it may be desirable perhaps to give his 
emended diagnosis,—stating the references up to the 
present date.
