 of eyes, with sides parallel behind eyes, posterior angles nearly right 

 angles, finely but rather distinctly punctured ; antennse short, third 

 joint nearly as long as, but more slender than, second, 5-10 transverse,

 seventh segment projecting, apical margin obtusely rounded, forehead 

 even. 



Under bark of trees, especially fir ; not common. Cobham and Sevenoaks, Kent ; 

 Pveigate ; Hainault ; Ricbmond, Surrey ; The Holt, Farnham ; Tonbridge; Smallbeath 

 and Kuovvle, near Birmingham ; Marktield, near Leicester ; Cannock Chase ; Needwood, 

 near Biirton-on-Trent ; Sherwood Forest ; Northumberland district ; Scotland, local, 

 Forth, Tay, Tee, and Moray districts. 



The peculiar shape of the head will distinguish this species ; it is 

 broader, shorter, and more narrowed in front than in the succeeding. 



K. cuspidata, Er. {inconsplcua, Heer., Thedura cusindata, Thoms.). 

 A very small, flat species, pitchy black or brown with the apex of the 

 hind body obscurely lighter ; head quadrate, broad and flat, closely and 

 distinctly punctured ; antenniB short, thickened towards apex, third 

 joint as long as second but more slender, 4-10 plainly transverse, 

 eleventh comparatively short ; thorax somewhat broader than long, 

 channelled ; elytra half as long again as thorax finely and rather thickly 

 punctured ; hind body with the basal segments finely and not thickly 

 punctured, apical segments impunctate, apex of seventh joint with a 

 long projecting spine in middle; legs yellow, tarsi short. L. H mm. 



Male with third, fourth, and fifth segments each with a pair of 

 tubercles on the upper side, spine on seventh larger than in female. 



Under bark of oak, fir, and other trees ; rather common in the London district, and 

 Southern and Midland counties, but 1 can find no record further north than 

 Scarborough ; it has not hitherto occurred in Scotland. 



The species .may at once be distinguished, apart from its size and 

 shape, by the distinct spine at the apex of hind body, which is present 

 in both sexes, but is most distinct in the male ; on either side of the 

 large .spine there is a small one ; these, however, are not always very 

 apparent. 



Uj cribriceps, Sharp. Broad, rather depressed, somewhat shin- 

 ing, pitchy -black, with the elytra yellowish, their apical angles fuscous ;
