TROG1D7E. TROX. 215 



In the neighbourhood of London this species is usually found 

 in the gravel-pits of Coombe-wood and Wimbledon. I have, how- 

 ever, taken the insect in other places, but it never appears to be 

 abundant. " Sundridge, Kent. 11 — Mr. Ingpen. " Spitchweek."

 L. Jenyns. 



Sp. 2. arenosus. Niger, thorace incequali, elytris suhstriatis, interstiths al~ 

 terras tubercu/is laevihus, apice longiits fasciculato-pilosis. (Long. corp. 3^ 

 lin.) 



Tr. arenosus. GyUenhal, i. 11.— Steph. Catal. 114. No. 1181. 



Less than the last: black: clypeus slightly acuminated in front, punctulated : 

 thorax unequal, channelled, punctured : elytra very obsoletely striated, with 

 a series of distinct subconic tubercles in each alternate interstice, anteriorly 

 smooth, shining, posteriorly furnished with tufts of rather long rigid cinereous 

 hairs : body and legs rather glossy-black. 



The smaller size of this species, with the form of its clypeus, and the more 

 obsoletely striated elytra, are its chief distinctions from the foregoing. 



Taken, though rarely, within the metropolitan district, and in 

 other parts. " In carrion on the sand-hills (near Swansea) not 

 common. 11 —/.. W. Dillwyn, Esq. " Lowestoft, Suffolk."— W. C. 

 Hewitson, Esq. 



Sp. 3. scaber. Niger obscurus, elytris punctato-striatis, interstitiis omnibus 



punctis fasciculato-pilosis. (Long. corp. 3 lin.) 

 Silpha scabra. Linne. — Tr. arenarius. Steph. Catal. 114. No. 1182. 



Dull black, or fuscous : clypeus rounded, punctate : thorax a little convex, obso- 

 letely channelled, punctulated : elytra oblong, punctate-striate, each inter- 

 stice with a row of reddish-brown tufts of hair, of which the alternate series 

 are largest : body and legs piceous. 



Smaller than either of the other species, and known by each interstice between 

 the striae having a row of pilose tufts. 



Not uncommon within the metropolitan district; in April last I 

 captured several specimens flying in my own garden at South 

 Lambeth. " A pair taken at Bottisham, in decayed wood." — Rev. 

 L. Jenyns. " Scarborough. 11 — W. Bean, Esq.
