Sp. 19. rugicoUis. Ovatus, ater, opacus, elytris obsolete 'pundato-striatis, inter- 

 stitiis scabrosis, thorace granulato, disco longitudinaliter rugoso. (Long. corp. 

 3i lin.) 



Otio. rugicoUis. Steph. Catal. 176. A^o. 1770. 



Ovate, black, opaque: head smooth posteriorly, between the eyes and the rostrum 

 thickly and closely wrinkled longitudinally : thot-ax globose, thickly and rather 

 coarsely granulated, the centre longitudinally wrinkled, with a moderately 

 deep channel: elytra ovate, scabrous, obsoletely striated, the strife punctate 

 and most visible on the sides ; the interstices having fine, short, pale hairs : 

 legs and antennce deep black. 



The only example I have seen of this very distinct species I cap- 

 tured at Dover in June, 1819. 



Sp. 20. maurus. Niger, subnitidus, parce cinereo-puhescens, aniennis pedibusque 

 rufo-piceis, thorace confertissime granulato, elytris ovatis punctato-striatis, 

 interstitiis sublwvibus. (Long. corp. 3f— 4^ lin.) 



Cu. maurus. Gyllenhal— Otio. maurus. Steph. Catal. 174. JVo. 1771. 



Black, slightly shining : head with the vertex smooth, the forehead sparingly 

 punctate : rostrum rugose-punctate, with a bifid elevated carina : thorax with 

 the sides rounded and dilated, the disc moderately convex and thickly covered 

 with rounded granular elevations, and a few cinereous hairs: elytra ovate, 

 with the apex obtusely rounded, very convex, regularly, but not deeply 

 punctate-striate, with the interstices slightly rugose, or nearly smooth, some- 

 times a little pilose : body opaque beneath, the breast deeply, and the abdomen 

 obsoletely punctate : legs and antennce rufo-piceous, pubescent, femora slightly 

 clavate. 



Two of my specimens of this insect (which appears rare) were 

 captured in Yorkshire, I believe near Scarborough ; the other in 

 Wales. 



Sp. 21. raucus. Niger, antennis pedibusque rufo-piceis, elytris profundi punctato- 

 striatis, pube grised fuscdque nebulosis, postics carinatis, thorace subcarinato.

 glabrous : rostrum thickly rugose-punctate, with a few griseous hairs, and an

 moderately convex, black, opaque, thickly rugose-punctate, with a few rigid 

 griseous hairs and an abbreviated narrow central carina : elytra ovate, with 

 the shoulders rounded, deeply and coarsely punctate-striate, with the inter-
