SCAPHIDIDiE. PTOMAPHAGUS. 7 



The shorter and thicker antennae and more acute apex to the elytra distinguish 

 tins species from Ph. fumata. 



Also an uncommon species : found near Hull, and in the me- 

 tropolitan district. " Bottisham." — Rev. L. Jenyns. 



Sp. 5. anisotomoides. Ovalis, convexus,nitidus, subpilosus,fusco-piceus, antennis 

 pedibusque pallide ferrugineis ; thorace postice recto. (Long. corp. § — f lin.) 

 Ch. anisotomoides. Spence. — Pt. anisotomoides. Steph. Catal. 72. No. 781. 



Glossy, oval, pitchy-black, clothed with very short grisescent down ; labrum 

 and palpi ferruginous ; antennas pale flavescent, as long as the thorax, some- 

 what capitate-clavate, the eighth joint much less than the adjoining, the ter- 

 minal large, subglobose and somewhat mucronate ; thorax with the hinder 

 margin generally palest, and straight : elytra ovate-convex ; legs pale-ferru- 

 ginous. 



Sometimes entirely of a pale testaceous. 



The great convexity of the body, and straightly truncate hinder margin of the 

 thorax, distinguish this species from the rest of the genus. 



Not very abundant; found near London, Hull, in Devonshire, 

 Norfolk, &c. " Bottisham." — Rev. L. Jenyns. " Moss from 

 Humby." — A. H. Davis, Esq. " Shropshire." — C. Darwin, Esq. 



Sp. 6. Wilkinii. Oblongus,fusco-piceus, antennis pedibusque jlavo-Jerrugineis ; 



thorace postics recto. (Long. corp. 1^ lin.) 

 Ch. Wilkinii. Spence.— Pt. Wilkinii. Steph. Catal. 72. No. 782. 



Oblong or sublinear, pitchy-brown, clothed with very short grisescent down : 

 palpi yellow ferruginous ; antennae the length of the thorax and of a yellow- 

 ferruginous; thorax with the hinder margin straight: elytra oblong, the sides 

 nearly straight, the apex rounded : legs yellow-ferruginous. 



Resembles Pt. velox, but is " distinguished from that by its proportionably 

 much larger and narrower body," which also well distinguishes it from the 

 preceding (Pt. anisotomoides), with which it agrees in the structure of its 

 antennae and thorax. 



Inhabits the county of Norfolk, and has been taken near London, 

 and in other parts ; but uncommon. " Salop." — C. Darwin, Esqi 



+ Sp. 7. Davisii. Oblongo-ovalis, postici angustiorijSubpubescens^fusco-brunneus, 

 thorace magno, convexo, antennis rufo-testaceis, clavd magna. (Long. corp. 

 flin.) 



Pt. Davisii mihi. 



Oblong-ovate, rather narrowed behind, slightly pubescent, of a fuscous-brown ; 

 the thorax very large, convex, thickly but finely punctured, the hinder margin 

 straight: elytra paler, and clothed with a longer protuberance than the thorax, 

 rather acuminated at the apex, which is somewhat acute and paler than the 

 Mandibulata, Vol. III. 31st May, 1830. c
