elytris subtruncatis, suturd nigra. (Long. corp. 1£ lin.) 

 Ni. impressa. Kirby MSS.f— Steph. CataL 79. No. 841. 



Ovate, slightly convex, testaceous-yellow, rather glossy, finely punctured : head 

 with a deep impression between the eyes, the latter black : thorax with the 

 anterior margin broadly, but not very deeply, emarginate, the sides rounded 

 to the hinder angles : elytra rather broad, deeply margined, the disc slightly 

 convex, the suture fuscous or black, the apex slightly truncate, with the 

 angles rounded : body pale testaceous beneath, with the legs paler. 



The short, ovate, subconvex form, with the subtruncate elytra and dark suture, 

 are the chief characters of this species. 



Under bark, near London, and in Suffolk. 



Sp. 18. pusilla. Oblongo-ovata, depressa, ferruginea, thorace subquadrato emargi- 

 nato, elytris apice rotundatis. (Long. corp. 1 \ lin.) 



Ni. pusilla. Illiger?— Steph. CataL 79. No. 842. 



Oblong-ovate, depressed, ferruginous : head thickly punctate ; eyes globose, 

 black; thorax subquadrate, with the sides nearly straight, the anterior margin 

 broadly emarginate, the disc rather convex, thickly but very finely punctate, 

 and slightly pubescent : elytra oblong-ovate, a little convex, thickly and 

 finely punctured, pubescent, the apex rounded, and slightly gaping towards 

 the suture: body beneath deep ferruginous; legs rufo-testaceous. 



The broad form, with the subquadrate emarginate thorax and rounded apex to 

 the elytra, serve to mark this insect. 



Under bark, throughout the metropolitan district, but not com- 

 mon; also in flowers. " Netley, on flowers."" — Rev. F. W. Eope. 



Sp. 19. pygmaea. Ovata, subdepressa, rufo-brunnea, punctatissima, niarginibus

 lin.) 



Ni. pygmsa. Gyllenhal. — Steph. Catal. 79. No. 843. 



Ovate, somewhat depressed, rufo-brunneous, very much and thickly punctured 

 head unequal, with the eyes globose, black ; thorax with the anterior mar- 

 gins broadly emarginate, the sides nearly straight, the margins broadly

 slightly pubescent, dull brown, with the margin narrowly pale testaceous, the 

 apex obtuse, rounded : body beneath dusky-brown, much punctured ; legs 

 pale testaceous. 



Differs from the foregoing in having the thorax more broadly emarginate, the 

 surface deeply punctured, the colour deeper, with the margins pale. 



Also found near London, beneath bark ; not common.

ohscurioribus, elytris apice subtruncatis. (Long. corp. 1 lin.)
