of the largest of numerous ones of triangularis before me. One 

 of the specimens was labelled as fuscocinereus in the Blackburn 

 Collection, but it is evidently not that species, which is 

 described as being much smaller and as having three smooth 

 brown patches at the base of each elytron : one humeral, one 

 median, and one sutural ; markings which, if constant, should 

 readily distinguish it from all others of the genus. It will 

 be noticed, however, that under Variety C of triangularis 

 a specimen is commented upon whose left side agrees with 

 the description of fuscocinereus. The elytra are without 

 glabrous patches, but a space behind each shoulder and the 

 tips of the elytra are darker at the positions where, in 

 triangularis, the derm is glabrous, but the clothing there is 

 almost, or quite, as dense as elsewhere. On the elytra, except 

 at the dark patches, the pubescence, to the naked eye, appears- 

 to be in numerous fine lines, this being due to very feeble 

 elevations; no part of the prothorax is distinctly glabrous, 

 and the oblique whitish lines of pubescence are not very con- 

 spicuous. The tarsi, for the genus, are comparatively short. 

 On the type male the eleventh joint of antennae ia 

 narrowed towards the apex, but the narrower portion has its 

 outline continuous with the basal portion, and the false suture 

 scarcely traceable. On a female in Mr. French's Collection 

 the apical portion is conspicuously marked off from the basal 

 portion by a notch, and the false suture is fairly distinct; 

 but on a second male the right antenna (the left is unfor- 

 tunately broken) is quite distinctly twelve- jointed, the twelfth 

 joint being about one-third the length of the eleventh. ( 2? ) 



Uracanthus fuscus, n. sp. 

 PL xxxii., fig. 7. 



d . Dark brown. Densely clothed with short stramine- 

 ous pubescence; middle femora with conspicuously dense 

 clothing along under-surface, the hind ones less densely 

 clothed. 



Head with median line narrow, base finely granulate, 

 clypeal suture rather deep and semi-circular, muzzle rather 

 short. Antennae just passing elytra, fourth to tenth joints 

 produced on one side at apex and rather flat, eleventh joint 

 about one-third longer than tenth. Prothorax distinctly 

 longer than wide, sides bisinuate, disc irregularly multi- 

 corrugate, with a small node on each side of middle. Elytra 

 not much wider than prothorax, moderately narrowed from 



(27) On the males of triangularis the false suture is usually 

 fairly conspicuous, and on two specimens in the Museum the 

 antennae are distinctly twelve-jointed ; on specimens of many 

 other species also the false suture is sometimes very distinct.
