 Soutbsea ; Gravescnd ; Heme Bay ; Weytnoutb ; Selsea Bill, under stones near shove. 

 I believe that it bas been taken in Ireland by Haliday. 



SSRISOBSnUS, Stepliens. 



Two European species are contained in this genus ; it may easily be 

 known from Corylojjhus by its pubescent upper surface, and also by its 

 broad, subparallel elytra, which are subtruncate, although rounded, at 

 apex; from Sacium it differs in having the posterior angles of the thorax 

 acute and strongly produced. 



S. lateralis, G}'11. Kather short, broad, subovate, with the elytra 

 subparallel, very gradually narrowed to apex which is broad and subtrun- 

 cate ; colour testaceous or reddish-testaceous, with the head blackish, very 

 distinctly apparent lieneath the transparent anterior margin of thorax ; 

 upper surface clothed Avith long pale pubescence ; antennge 10-jointed ; 

 thorax subtransverse, semicircular, with the posterior angles aciite and 

 produced, scarcely punctured ; elytra consideral:)ly convex towards base 

 and gradually depressed towards apex, very finely punctured, broader at 

 base than thorax ; legs testaceous, L. § mm.

SACIUM, Le Conte {Clt/peasfer, Latr.). 



This genus is very widely spread over the surface of the globe, and will 

 probably prove to be a very numerous one. Several very interesting species 

 have lately been discovered by Mr. Champion in Central America, and have 

 been described by Mr. Matthews; it is distinguished by its 11-jointed 

 antenna3 from all our other CorylopliidjB, and may be separated from 

 Sericodenis, to Avhich it is most closely allied, by having the posterior 

 angles of the thorax right angles and not produced ; eight European 

 species are known, of which one only is found in Britain ; only two 

 specimens, however, have hitherto been taken in this country. 



S. pusillusn, Oyll. Oblong-oval, not strongly convex, rather shin- 

 ing, clothed with thick pale pubescence ; colour black with the thorax 

 testaceous with fuscous disc ; the colour of the thorax is, however, vari- 

 able and sometimes is pitchy-black with tAvo spots at apex, and the 

 margins, yellowish-brown ; upper surface very finely punctured ; thorax 

 not transverse, with the posterior angles right angles, not produced, base 

 slightly produced before scutellum ; legs reddish-brown or fuscous. L. 

 H-2 mm. 



Under bark ; very rare; one specimen was taken many years ago by Mr. Wollns(o:i, 

 but was, 1 believe, accidentally destroyed, and a second bas been recently found on an 

 oranje in Birmingham by Mr. W. G. Blatch.
