the same joint subcapitutc-truncatc" : htud rounded, dellcxcd, united to tiic 

 thorax by a slender neck : thorax gibbous, rounded, rather narrowed behind, 

 and produced in front with an elongate hornliive process, projecting over 

 the head, and mostly serrated towards the apex: eyes prominent: elytra 

 broader than tlie thorax, rounded at the apex: body slightly convex: legs 

 rather long, cursorial : tihiw with very minute spurs at the apex : tarsi with 

 the penultimate joint slightly bilobed. 



Notoxus and Anthicus differ from the other genera of this family 

 by having the head united to the thorax by a distinct neck, and the 

 former genus may be at once known, not only from Anthicus but 

 from the other genera of the family, by having the anterior edge of 

 the thorax produced into a hornlike process, which extends over the 

 head. The species appear to frequent sandy districts.

Rvfo-festaceous, with a silken pubescence : head with the forehead and crown 

 fuscous ; eyes black : thorax ferruginous, anteriorly fuscescent, and pro- 

 duced into an elongate horn, rounded at the apex, and serrated on both 

 sides ; elytra thickly and finely punctured, pale testaceous, each with a 

 spot on the outer margin, behind the shoulders, and a larger one behind the 

 middle, mostly connected by a streak luith a third spot at the base near the 

 scutellum, and forming a lunular streak, which rarely touches the suture, 

 black: body beneath, legs, and antennae, pale testaceous. 



The spots on the elytra are extremely variable in size, and are sometimes so 

 coalesced as to nearly cover the entire surface, leaving only a slender irre- 

 gular marginal line, and the apex of the elytra pale : all intermediate shades 

 of confluence occur. 



Not uncommon occasionally in the lane, about the middle of June, 

 by the side of Coombe Wood, leading from the Robin Hood ; and 

 very abundant in Sandy-lane, near Richmond; also found near 

 Ripley and Hertford. " Weston-super-mare, plentifully."" — G. 

 Waring, Esq. " Sandy-lane, Richmond, in abundance." — Rev. T. 

 T. Haverjield. "Near Liverpool."" — Rev. A. H. Matthews. 

 " Often very abundant on Crwmlyn and Sketty-burrows, and on the 

 naked sand-hills." — L. W. Dillivyn, Esq.
