HISTEIUDiE. HISTER. 145 



viated, within the apex a transverse impression ; tibiae very much dilated, the 

 anterior with four teeth, the outer one being bifid and the inner one minute : 

 antennae with the club ferruginous. 

 The oblong form of this species, with the punctate space between the lateral 

 striae on the thorax, and the ferruginous club of the antennae, at once distin- 

 guish it from the others of the genus. 



Rare : specimens have been taken near London, and in Here- 

 fordshire. " Copenhagen-fields." — Mr. Ingpen. 



Sp. 3. unicolor. Ater, nitidus, elytris striis tribus integris externis, tibiis an- 

 ticis tridentatis, dente extimo bifido. (Long. corp. 2^ — 4 lin.) 



Hi. unicolor. Linne. — Wood, i. pi. v. Steph. Catal. 100. No. 1048. 



Somewhat rounded, deep glossy-black : thorax convex, as broad as the elytra 

 behind, but narrower anteriorly and deeply notched; lateral striae rather 

 faint, the outer one rarely extending beyond the middle of the margin : 

 elytra rather convex above, with the lateral margins much dilated, each with 

 seven subpunctate slender striae, of which the three nearest to the suture are 

 abbreviated anteriorly, the three next entire, and the outer one again abbre- 

 viated ; on the shoulder is frequently a faint oblique stria : legs stout ; an- 

 terior tibiae externally tridentate, with the outer tooth bifid : antennae black. 



Differs from the two foregoing species by its rounded form, &c. from the fol- 

 lowing by having three abbreviated striae on each elytron adjoining the 

 suture, the outer striae on the thorax abbreviated, and the tibiae tridentate. 



Extremely abundant in the neighbourhood of London, and I be- 

 lieve throughout the kingdom, inhabiting dung, dead animals, the 

 putrid sap of trees, &c. " Netley, Oxford, Southend, &c." — Rev. 

 F. W. Hope. " Black Hall:'— T. C. Heysham, Esq. " Some- 

 times found (near Swansea)." — L. W. Dillwyn, Esq. 



Sp. 4. cadaverinus. Ater, nitidus, elytris externe quinque striatis, tibiis anticis 



sex dentatis. (Long. corp. 2g — 3| lin.) 

 Hi. cadaverinus. Ent. Hefte.— Steph. Catal. 100. No. 1049. 



Somewhat rounded, glossy-black: thorax convex, obsoletely punctate on the 

 . margin, with the lateral striae deep, and both extending to the base, the outer 

 one somewhat remote from the margin and waved : elytra slightly convex, 

 each with five nearly entire striae, two abbreviated ones adjoining the suture, 

 and two other obsolete ones at the base, between the two exterior, which are 

 somewhat divided by a humeral callous : anterior tibiae dilated, with five or 

 six small denticulations on its outer margin. 

 In form resembling the preceding insect, from which it abundantly differs by 

 the depth and elongation of the thoracic striae, the integrity of the third stria 

 from the suture, the denticulations on the anterior tibia?, &c. 



Also abundant in Britain, frequenting the same haunts as the 

 last. " Salop, Gloucester, South Wales, Deal, Southend, &c." —
