124 MANDIBULATA. — COLEOPTERA. 



remarkable rotundity of its elytra, compared to its short transverse 

 tliorax: the rostrum is broad, short, obsoletely channelled and 

 divided from the head, as it were, by a transverse suture : the 

 species mostly frequent the coast, but one occurs in plenty in sandy 

 inland districts. 



Sp. 1. geminatus. Niger dense fusco squamosus, cinereo lineatus, elytris albido 



setosis. (Long. corp. 2 — 4 lin.) 

 Cu. geminatus. Fabricius. — Ph. geminatus. Steph. Catal. 174. IVo. 1779. 



Black, densely clothed with fuscous scales, and lineated with cinereous or hoary: 

 head varied with cinereous or fuscescent scales, and a slight concolorous pu- 

 bescence, the forehead somewhat depressed : thorax finely rugulose^ punctate, 

 very densely squamose, with its under surface and two broad, curved, dorsal 

 lines ashy-white, the rest obscure fuscous, with a griseous pubescence : scu- 

 tellum black : elytra very globose, faintly punctate-striate, with the interstices 

 flat, finely coriaceous, densely clothed with fuscous or ashy scales, varying 

 considerably in diflFerent individuals; sometimes they are of an uniform 

 ash-colour or vice versa ; at others they are alternately fuscous and cinereous, 

 and sometimes the colours are partially tessellated, and in general the edges 

 are more or less indented; the surface is also sparingly clothed with an ashy 

 rigid pubescence, especially towards the apex : antennse fusco-ferruginous. 



Extremely variable in the disposition of the coloured scales, as well as in 

 size. 



Extremely abundant on most parts of the coasts of Great Britain. 

 " Common on the sand-hills (near Swansea), and on the stalks of 

 Arundo arenaria." — L. W. Dillwyn, Esq. " Southend, Deal, Bar- 

 mouth, 8ic."—Rev. F. W. Hope. " Tynemouth."— G. Walks, 

 Esq. " Cramond."— Eet>. W. Little. 



Sp. 2. parapleurus. Niger, hispidus, elytris striatis fuscis maculis lateribusque 



albidis, antennis rufis. (Long. corp. 3 lin.) 

 Cu. parapleurus. Marsham. — Ph. parapleurus. Steph. Catal. 175. No. 1780. 



Black ; head finely punctured, clothed with fuscous scales : thorax the same 

 and slightly pilose : elytra fuscous, punctate-striate, with the sides and some 

 irregular spots white; the interstices slightly depressed, and having a few 

 cinereous hairs, especially towards the apex : body beneath and legs black, 

 with a whitish pubescence: rostrum blacky punctate: antennae rufous. 



Less abundant than the foregoing, of which I suspect it may be 

 a mere variety. "On the sand-hills (near Swansea), not uncommon."
