134: CLAVICORNIA. [PiiU2im. 



longer or broader than head, deeply foveolate-punctate, with a narrow 

 central channel in front not reaching to middle, and on each side anarroAV 

 impressed line converging from base to beyond middle, sides slightly 

 rounded, somewhat constricted behind ; scutellum large ; elytra rather 

 long, narrow, and transparent, elongate-oval, broadest before middle, 

 closely and rather deeply asperate in transverse rows, somewhat narrowed 

 behind ; legs rather long, clear yelloAV, tibia? slightly dilated ; under-side 

 castaneous, mouth, coxa% and abdomen lighter. L. | mm. 



Very rare ; a single cxairple was taken by Mr. Matthews under bark of dead oak in 

 Sherwood Forest. 



The species is very distinct, and may at once be known by the sculpture 

 of the head and thorax ; it partially corresponds to T. variulusa in the 

 genus Triclioptcryx. 



TUlItliimVT/K, Motschulsky. 



This genus contains one European and one American species ; the 

 former of these is common in hotbeds in many parts of the country ; it 

 is very smooth and shining like an elongate Ptenidium, and is easily 

 distinguished Ijy the very deep longitudinal furrows on the thorax. 



m. trisiilcatum, Aube {minutissimvm, Gill). Elongate-oval, 

 convex, pitchy-black or deep black, very shining, almost glabrous, very 

 sparingly clothed with extremely short silvery hairs ; head moderate, alu- 

 taceous, eyes small, scarcely prominent, antennae rather obscurely yellow ; 

 thorax alutaceous, with sides strongly rounded, contracted behind, 

 broadest behind middle, posterior angles acute, with a very deep median 

 furrow and a shorter furrow on each side, diverging in front ; scutellum 

 large, broad, triangular, with a deep conical fovea not reaching base, and 

 a smaller oblique fovea on each side ; elytra ovate, very shining, extremely 

 finely and remotely punctured, apices lighter ; abdomen slightly exserted, 

 rather acute ; legs clear yellow ; under-side pitchy, with mouth, coxse, 

 and last segment of abdomen clear yellow. L. | mm. 



In mos?, vegetable refuse, hot-beds, &c. ; not uncommon in some loralities ; it 

 seems to be rare in the London district ; Toubiidge ; llepton, Burton-on-Ti-eut, 

 (ommon, Knowle, and other Midland localities; Baruwood, Gloucester; it is not 

 recorded from the North or from Scotland ; my impression is that it is very widely 

 distributed, but is overlooked on account of its minute size and sluggish movements. 



ACTZBIUM, Matthews. 



This very distinct genus contains eight species, three from Europe, 

 two from British Columbia, one from the Sandwich Islands, one from 

 Central America, and one from New Zealand ; it is probable that many 

 more will be discovered ; they are easily distinguished from Plillam by 

 having the abdomen entirely covered by the elytra.
