138 COLEOPTERA. 



not have been drawn up from the specimen of O. concinnum 

 which now stands as the exponent of the species in his cabinet. 

 The first example of this species which came under my notice 

 was taken by Mr. Wollaston at Penheale, Cornwall ; I sub- 

 sequently met with it at Colney Hatch, Hampstead, Darenth 

 and Shirley, and Mr. Edwin Shepherd has captured it near 

 Putney. It occurs, but very sparingly, beneath the bark 

 of decaying trees.

Col. 31 (1858). 

 The descriptions of O. exiguum, Steph. Mand. v. 3-50, 13 

 (1834) ; Man. Brit. Col. 428, 3427 (1839), are abridged 

 from Gyllenhal, Ins. Suec. ii. 218, 17 (1810) ; the insect, 

 however, so designated by the Swedish Entomologist, appears 

 to have been unknown to Stephens. Mr. Wollaston captured 

 it at Killarney, and I have taken it on several occasions in 

 the neighbourhood of London. 



84. Omalium pygm.eum, Payk., Eric. ; Waterhouse, Cat. 



Brit. Col. 32 (1858). 

 This species appears to be unrepresented in Mr. Stephens's 

 Collection : his descriptions, Illust. Mand. v. 356, 30 (1834) ; 

 Man. Brit. Col. 430, 3444(1839), are evidently copied from 

 Gyllenhal, Ins. Suec. ii. 223, 22 (1810), and therefore apply 

 to the insect before us, which occurs, but very rarely, in 

 boleti and beneath bark of decaying trees. The first spe- 

 cimen which came under my observation was captured near 

 Norwich by Mr. Wollaston. I have taken solitary ex- 

 amples at Colney Hatch and near Croydon, and Dr. Power 

 iias secured an individual near Alverstoke, Hants.
