6S COLEOPTERA. 



cornis, Sturm, is a mere immacalate variety of O. hicolor, 

 Fab., and does not occur in this country. I presume Mr. 

 Crotch has satisfied himself tliat there is no sufficient descrip- 

 tion of Leach's species, as it is both owned and deposed in 

 the same sentence. 



46. Atomaria fumata, Erichs., Ins. Deutschl. iii. 378, 3 ; 

 G. R. Crotch, Cat. Brit. Col. ; id. Zool. 8999 (1864). 



The exponents of the above species in our Collections, I 

 believe, obtained their name from a specimen formerly in the 

 possession of Mr. Wollaston, but recently given by him to 

 me, to which Dr. Kraatz affixed a note ^^ fumata var. vi- 

 detiii'." This insect was taken by the late H. Squire at 

 Hammersmith Marshes, where it has since been found by 

 Dr. Power, myself, and other metropolitan collectors. My 

 attention having been, for the first time, directed to these 

 Hammersmith specimens by Mr. Crotch's remarks, I found 

 that they would not agree well with the description given 

 by Erichson (loc. cit.) for A. fumata ; which insect should 

 be like ?i?'g?'ive?itris, Steph. (nana^ Er.), but larger, more 

 thickly punctured, with the thorax longer, and not so con- 

 tracted in front. 



I have, however, subsequently (on 12th June last) taken 

 a specimen at Mickleham, by sweeping under fir trees, which 

 answers in every respect to Erichson' s fu7nat a ; and have 

 since received several examples, also undoubtedly that species, 

 from Mr. T. J. Bold, who took them in a fungus on a fir 

 stump near Newcastle. 



The Hammersmith specimens are invariably found in wet 

 places, by cutting grass, &c., and seem to be rather smaller 

 and riatter than the above-mentioned examples, with their 

 elytra shorter, not so pointed behind, and exhibiting a more 

 or less conspicuous livid stain near the apex, which diminishes
