Head smooth, 036? prominent, convex between frontal prnoves, which are 

 wide, deep, and parallel. Frot/iorax cordate, half as wide again a:s lonfj-, con- 

 tracted slightly more iu front than behind, sides moderateh' rounded and 

 sinuate near the bind angles, which are sharp, but a liitle more than right, 

 owing to the slight obliquity of base at sides, a rather feebly developed carina 

 just above them, basal foveae small but fairly deep, and at some distance from 

 sides, sm'face smooth, with a few punctures at sides of base and in foveae, 

 basal depression uneven in middle, but hardly punctate. Elytra ovate, rather 

 Hat, basal border reaching stria 5, punctate-striate, all the striae deep through- 

 out, the punctures fine, disappearing at two-thirds from base, apical stria and 

 .0 continuous, 8 joining 9 at a fourth from base, inner intervals moderately flat, 

 outer ones more convex, 3 with tliree well-marked pores, all adjoining stria 3, 

 at a fourth, a half, and three-fourths, the setiferous pore generallv to be found 

 in the apical stria is placed on interval 5, adjoining stria 0, and it is usually 

 followed by 2-4 smaller non-setiferous pores.

I have not compared this species with any other, because I know of 

 none like it. In some respects it is allied to the group generally 

 designated Plata pints Motsch., but it differs from all the species of Bem- 

 hidium known to ma in its excep)tionally deep and clearly cut striae, and 

 in the presence of three pores on interval 3. In the Palaearctic species 

 of this genus there are normally two pores, but in one or two, grouped 

 under the name Ocys, there is only one : for the species just described I 

 propose tlie group name Triporus. 



Bemhidium (JPeri/pJius) vitalisi, sp. nov! 

 Length 5 mm. ; wing 1'8 mm. 



Black, shiny, with faint aeneous reflection : joint 1 of antennae, base of 

 palpi, and legs (except knees) reddish, a faint dark red spot on elytra at apical 

 fourth. 



Head smooth, moderately convex, eyes prominent, frontal grooves wide, 

 fairly deep, parallel, with some faint striation at bottom. Prothorax cordate, 

 rather less than half as wide again as loi.g, ecLually contracted at extremities, 

 sides gently rounded, sinuate rather before the rectangular hind angles, basal 

 foveae deep and rounded, bounded outwardly. by a strong carina, surface 

 smooth, base with a little coarse but rather vague puncturation. Elytra oval, 

 fairly convex, punctate-striate, the striae not very deep but closely punctate, 2 

 fainter near apex, the remainder -especially the outer ones— obsolescent 

 behind, but 7 clearly marked on basal half, apical stria sharply incised, intervals 

 slightly convex.
