COLEOPTERA. — CARABIDJE. 91 



phihis are of small size, and have the aspect of the Cicindelida?. 

 Tliey are found in damp situations, and on the margin of streams, &c. 

 running with velocity in the sunshine. The former genus is dis- 

 tinguished by the embossed spots on the elytra, and the latter by the 

 brilliant smooth shining surface of their bodies. Mr. G, Waterhouse 

 has published a monograph upon the latter in the Entom. Magazine, 

 No. 2., in which he has described eighteen British species, some of 

 which are not probably sufficiently distinct, Mr. Stephens having re- 

 duced their number to six. Amongst the exotic genera are to be 

 mentioned Procerus Merjerle, containing the largest species of the 

 subfamily, having the labrum entire, and the anterior male tarsi 

 simple. The species are 'iQ\\ in number, and generally of a rich purple 

 colour, with the elytra very rugose. They inhabit the mountains 

 of Turkey and adjacent countries. The rare African genus, Tefflus, 

 is also of large size, and resembles the Carabi in form, but the labrum 

 is entire, and the thorax suborbicular. It has been generally con- 

 sidered allied to Procerus, but M. Brulle has removed it from the 

 Carabides and placed it in his subdivision Panagiens, regarding it as 

 more nearly allied to certain large exotic Panagrei. I have figured 

 it in Griffith's Animal Kingdom^ Insects, pi. 30. The interesting 

 genus Omophron {Jig. 4. lo. O. limbatum), whose larva I have 

 above described, is of a rounded convex form, thus approaching the 

 Dyticidae ; the thorax is short and slightly lobed behind, covering the 

 scutellum ; the basal joint of the male tarsi alone is dilated. The 

 species are varied in their colours, with green and yellow ; they are of 

 small size, not exceeding one-third of an inch in length, and are found 

 upon the banks of streams. The relationship of this genus to the 

 Water-beetles has been pointed out above ; but its true situation is 

 evidently in this subfamily, which is confirmed by the similarity in 

 its habits and the structure of its trophi with the Elaphridea and 

 allied genera. 



The fifth subfamily Bembidiides (Subulipalpi Latr.) is distin- 

 guished by the terminal joint of the maxillary and labial palpi being 

 very minute and acute {Jig. 4. 18. 19. maxilla and labium of No- 

 taphus). The anterior tibiae are always notched on the inside near 

 the tip, and the insects are of small size, and generally ornamented with 

 metallic tints {fig- 4-. 17. Lopha 4-maculata). The typical genus, 

 Bcmbidium Latr., is nearly alii d in general characters to the
