(Sub. -Gen. Phosphug-a, Leach. (Peltis, Eeitter nee auct.) 



This sub-genus contains one variable European species, which has been 

 subdivided by some authors into three or four separate species ; it appears, 

 however, to be best to retain them as varieties ; according to Reitter, 

 Geoffrey first applied the name of Peltis (in 1762). to Silpha atrata; he 

 therefore substitutes the name for that of Phosphnga, and revives 

 Laicharting's name Ostoma for the genus of Trogositidse usually known 

 as Peltis. 



S. atrata, L. Oval or oblong-oval, moderately convex, shining 

 black ; head elongate, antennae long and slender with the three last joints 

 forming a rather distinct club ; thorax forming an almost complete semi- 

 circle, with disc somewhat raised in middle, and depressed at sides, 

 closely punctured at sides, posterior angles obtusely rounded ; elytra with 

 strong margins, strongly and rugosely punctured, with the suture and 

 three lines distinctly elevated into keels, without tubercle behind middle ; 

 legs slender and elongate. L. 10-11 mm. 



In carcases, moss, rotten wood, under dead bark, &c. ; common and generally dis- 

 tributed throughout England and Scotland ; apparently represented mostly in Ireland 

 by the var. subrotundata. 



F. Irunnea, Herbst. Of a reddish-brown colour and rather small ; 

 this variety appears to be chiefly found in high districts. L. 9-10 mm. 



F. subrotundata, Steph. Larger and more ovate than the type form, 

 with the elytra considerably more rounded at sides, and often of a 

 brownish or reddish-brown colour ; the centre of the disc of thorax is 

 more sparingly punctured, and the central raised line is the longest. 

 L. 11-14 mm. 



This variety has been recorded from Glanvilles Wootton, Devonshire, and South 

 Wales, but appears to be rare in England ; in Ireland, however, it is very common in 

 several localities ; lleitter gives Scotland only as a locality, but has probably made a 

 mistake between this country and Ireland ; 1 have not seen a Scottish specimen, and 

 Dr. Sharp does not record it from that country. 



CHOLEVINA. 



This family has been divided by Eeitter into three groups, Bathyscije, 

 Cholevae, and Colones ; the former of these comprises a large number of 

 genera and species, the majority of which have been comparatively 

 lately described ; the other two comprise three or four genera, one or two 

 of which have been, however, further subdivided by some authors ; the 

 anterior coxae are cylindric-conic, prominent, and contiguous ; according 

 to Horn they have no trochantcr, but this does not appear to be invariably
