NEW BRITISH SPECIES, ETC., IX 1871. 49 



impression that it had been already exhibited by Mr. Crotch 

 at some meeting of the Entomological Society: but I have 

 failed to discover any record of such exhibition. 



Distinguished from 31. pidlaj GylL, by its some'>Yhat 

 thicker and distinctly finer punctuation, and by the sides and 

 hinder angles of the thorax, the elytra, (except near the 

 scutellum and at the outer posterior angles,) apex of abdo- 

 men, ventral segments beneath, legs entirely, and antennas at 

 base, being rufo-testaceous. 



Associated with Formica cunicularia, according to 

 Kraatz. 



7. Aleochara villosa, Mann., Brach., Ql ; Er., Gen. et 

 Spec. Staph., 177; Kraatz, Ins. Deutschl., ii, 94; 

 T. J. Bold, Cat. Ins. Northumb. and Durh. (Revi- 

 sion of Coleoptera), 1871, 114; Ent. Mo. Mag, vii, 

 275; D. Sharp, Ent. Mo. Mag., viii, 74. 

 Two specimens of an Aleocharaj somewhat doubtfully 

 referred as above, have been taken near Newcastle-on-Tyne 

 (for one of which I am much indebted to Mr. Bold) ; and 

 Dr. Sharp has also found the same species at Braemar. 



As described, these insects differ from A. lanuginosa in 

 having; lono;er and thinner antennae, of which the 2ud and 

 3rd joints are equal in length, and the 4th joint is longer 

 than broad; in being flatter, more parallel, and much less 

 shining, and with proportionately narrower thorax, and the 

 elytra (which are distinctly and thickly punctured) not so 

 distinctly sinuate at the outer angles. The punctuation of 

 the abdomen differs from Kraatz's description in being only 

 more delicately punctured than in lanuginosa, with the 

 apical segment very evidently and tolerably closely punc- 

 tured. The whole insect much resembles A. grisea, Ktz.
