140 MANDIBULATA. — COLEOPTERA. 



Found beneath masses of chalk, near Dover, and also in the 

 vicinity of Bristol. 



Sp. 2. semistriata. Oblongo-ovata, piceo-nigra, pubescens, antennis pedibusque 

 pallidis, elytris basi tenue striatis. (Long. corp. 1^ — 1^ lin.) 



By. semistriatus. Illiger. — Si. semistriata. Steph. Catal. 99. No. 1037. 



Oblong-ovate, pitchy-black, pubescent: head punctured: thorax somewhat 

 aeneous, punctured, clothed with cinereous pubescence : elytra also somewhat 

 aeneous, attenuated towards the apex, thickly punctured, with a scattered 

 ashy pubescence, with a single entire stria at the suture, and several abbre- 

 viated ones at the base, vanishing before the middle : legs and antenna; pale 

 rufescent. 



The pale rufescent legs and antennae of this species, with the abbreviated striae 

 on the elytra, distinguish this from the foregoing species, and the latter 

 character from the following. 



Not uncommon in Battersea-fiekls, and in other places in the 

 vicinity of London, at the roots of grass. " Common in putrid 

 fungi in woods (near Swansea), and is often rather plentiful about 

 the beginning of summer, in Crwmlyn Burrows." — L. W. Dillwyn, 

 Esq. " Glanville's Wootton."— J. C. Dale, Esq. 



Sp. 3. picipes. Oblonga, nigro-subcenea, nitida, pedibus rujis, elytris prqfundiils 



continue striatis. (Long. corp. 1| lin.) 

 By. picipes. Olivier. — Sim. picipes. Steph. Catal. 99. No. 1038. 



Oblong, of a somewhat aeneous black: head aeneous: thorax clothed with 

 griseous pubescence: elytra elongate, acuminated at the apex, regularly striated, 

 each elytron with ten rather deep, scarcely punctate, striae, reaching nearly to 

 the apex, the interstices minutely punctate : legs and antennae rufo-testaceous. 



As long, but not so broad, as the foregoing species ; from which it also differs 

 in having the striae on the elytra produced nearly to the apex of the latter. 



Less common than the last; I have taken it in the neighbour- 

 hood of London, and it has been sent to me from the vicinity 

 of Bristol. " On Crwmlyn Burrows, not uncommon." — L. W. 

 Dillioyn, Esq.
