pubescence round it, which is broad at its base and 

 sides, but very narrow round the apex ; the space on 

 each side of this is finely punctured and brassy. 



The under flanks of the prothorax are dull seneous, 

 with numerous large, deep punctures. 



The prosternal process is sometimes channelled in the 

 middle, sometimes nearly flat, and one example in this 

 Museum has it slightly convex. This difference does not 

 appear to be either sexual or specific. Some specimens 

 have a few punctures in the middle of the process.

Pycnohothris triincatclht, n. sp. 



Closely resembles P. ohscurcUa, Th., in form and 

 aj^pearance. Obscure coppery brown, with thickly and 

 strongly punctm'ed thorax, and closely and strongly 

 punctate- striate elytra. It is, however, at once distin- 

 guished by the elytra being a little truncate at their 

 apex, the outer angle of the truncature slightly dentiform, 

 and by the large lateral spots being round. The under 

 side is almost entirely of an obscure coppery purple in 

 the only example which I have seen. The anal segment 

 resembles that in ohsciirella.

Pycnohothris cuprifera, Lap. & Gory. 



This species is scarcely distinguishable above from 

 P. obscurella, Th., but it appears always to want the very 

 small brassy spot on the margin of the elytra, just 

 before the apex, which exists in obscurella. Below it is 

 easily separated by the apical segment of the abdomen ; 

 this has the anal plate very small, round (or slightly 

 oval), surrounded by a ring of yellow pubescence, which 

 is sunk below the surface of the plate itself ; the margin 

 beyond this is impunctate, shining, deep purple, raised, 

 and somewhat thickened ; the penultimate segment has 

 its apical margin smooth. The prosternal process is 

 moderately thickly punctured in the middle, longi- 

 tudinally impressed in the middle. The under flanks of 

 the prothorax are brassy and irregularly, and more 

 finely punctured than in P. obscurella.
