28 MANDIBULATA. COLEOPTERA. 



The linear-elongate body of this genus, combined with the narrow- 

 ness of the tliorax behind, exclusively of other differences, at once 

 point out the more obvious external distinctions between it and the 

 foregoing ; and from Cistela the same characters, combined with the 

 cleft apex to the mandibles, the shorter antenna^, distinctly securiforn 

 palpi, &c. remove it. The species — of wliich there are many foreign 

 — are generally found beneath the bark of decaying trees, probably 

 feeding upon the fungi. 



Sp. 1. scapularls. Lincari-ehngatus, niger, ore, antennarum hasi tibiis tarsis 



maculuque humerali elytrorum rujo-testaceis. (Long. corp. Sg — 3 lin.) 

 My. scapularis. Gyllenhal. — Steph. Catal. 245. No. 24-43. 



Linear-elongate^ black, shining : head distinctly but deeply punctate, with a 

 deeper transverse stiga between the antenna; : mouth piceous, palpi pale 

 testaceous : thorax sparingly but rather deeply punctate, pubescent, with a 

 large ovate fovea on each side within the basal angle : elytra delicately but 

 obsoletely crenate-striate, pubescent, with an ovate oblique rufo- testaceous 

 spot on the shoulders, of variable size: femora black; tibiae and tarsi 

 slender, entirely rufo-testaceous ; antennae black, with the three basal joints 

 rufo-testaceous. 



I have occasionally met with this insect in considerable plenty in 

 June, at Coombe-wood, especially about twenty years ago, when I 

 captured nearly fifty out of an old rotten post ; since which period I 

 have taken one or two specimens in Copenhagen-fields and near 

 Ripley. The insect has been found in Norfolk. " Taken by Mr. 

 Hall in Kensington-gardens, July, 1802." — Marsham MSS. " In 

 rotten willows, near Bottisham, occasionally." — Rev. L. Jenyns.

Genus CCCCXLIII.— Cistela, Fabricius. 



Antennce rather shorter than the body, inserted near the inner margin of the 

 eyes, and composed of obconic, subobconic, or obtrigonal joints, of which 

 the second is always minute, the third generally more or less elongate, and 

 the terminal one rather slender, and acuminated, or obtuse. Palpi unequal, 

 maxillary elongate, with the terminal joint incrassate, compressed, trian- 

 gular, subacuminated : vientum coriaceous, subquadrate : head porrect, 

 narrower than the thorax, the latter broadest behind, nearly semicircular ; 

 body oblong, arched, attenuated to each end : elytra and wings ample : legs 

 rather long ; tibiw slender, with long acute apical spurs ; tarsi with simple 

 joints: c/aiw^ denticulate.
