COLEOPTERA. — BRACIIELYTRA. 1*73 



found in the same locality. See further hereon, Burrell and Haworth, 

 in Entom. Trans, vol. i. ; Kirby and Spence, Introd. vol. iv. p. IGG. ; 

 my additional observations on the Brachelytra, in Zool. Journ. 

 No. 12., and Stephens. Illustr. B. E. Mand. iii. 366. 



The genus Coprophilus Latr. (H, An, 2d edit., Elonium Leach) 

 appears to connect the Oxytelides and Omaliides, having the form of 

 an Oxytelus and the maxillary palpi of Omalium. In TrogophIa;us 

 3Iami. the tibiae are unarmed. 



The fourth subfamily, Omaliides ( A pplatis Z«^r.), is distinguished 

 by the flatness and breadth of the body (^/iff. 15. 20. Omalium rivu- 

 lare), which is generally of small size, and of black or obscure colours; 

 the tibiae are not externally spinulose ; the head is exserted ; the upper 

 lip entire; the maxillary palpi 4-jointed (Jiff. 15. 21.), and the tarsi 

 distinctly 5-jointed {Jiff. 15. 22.) ; the elytra are comparatively larger 

 than in the other subfamilies, those of Anthobium, a genus which fre- 

 quents flowers, nearly covering the abdomen, whence Marsham intro- 

 duced this species into the genus Silpha. The species in general are 

 found in decaying vegetables, dung, moss. &c. The type of the genus 

 Lesteva was named Staphylinus caraboides by Linnaeus; and from its 

 resemblance to some of the subcortical species of Brachinides, Mr. 

 MacLeay was induced to regard it as constituting the connecting 

 link between the Geodephaga and Brachelytra, and thus effecting the 

 circularity of the arrangement of the Chilopodomorphous Coleoptera. 



Germar, in the fourth volume of his jSIagasin der Entomologie, 

 p. 410., noticed the remarkable fact that some species of Omalium are 

 furnished with a pair of posterior ocelli ; and Dalman and Kirby 

 [Introd. iii. 506.) also observed them in some species of Lesteva. They 

 have been regarded by some writers merely as tubercles ; but on ex- 

 amining them with a strong lens, they appear to me to present all the 

 appearance of ocelli, being very cons])icuous in the black species, in 

 which they are of a red colour. 



The fifth subfamily, Tachyporides (corresponding with the Micro- 

 cephali, and genus Aleochara Latr., the tribes Tachinides and Aleo- 

 charides of Mannerheim, and the family Tachyporidac of MacLcay 

 and Stephens), is distinguished by having the head generally deeply 

 immersed in the thoracic cavity, without any distinct neck {Jiff. 15.
