" A little larger than H. venustulus, Boh., Catal., p. 441, and of the 

 same colour, the lateral sutures of the frontal part are also very marked, 

 but the two impressions beginning at the angle of these sutures and 

 which have a tendency to unite behind in the centre of the vertex are 

 very little marked in this species, but very distinct in S. venustulus; the 

 prothorax is more convex ; the shape of the elytra is similar, but the 

 intervals are much less vermiculate, i.e., the punctures although 

 disposed in more or less regular series, do not unite in such a way as 

 to form a ridge on each side of the striae which are much wider, and 

 the punctures on the three intervals are broader. Length 6 J mm. ; 

 width 3 mm." 



Hab. Mozambique (Quilimane) teste H. J. Kolbe ; occurs in

Mitteil. Naturh. Mus., Hamburg, xiv., Jahrg., 1897, p. 79. 



Dark bronze, moderately shining on the upper side, and 

 briefly but thickly pubescent ; antennae black except the two basal 

 joints, which are flavous ; femora piceous ; tibiae rufescent ; head and 

 labrum very closely and deeply punctured, and briefly, although 

 densely, pubescent ; prothorax gradually rounded laterally, truncate 

 at both ends, not sinuate laterally towards the basal angle, very 

 narrowly grooved longitudinally in the middle, very roughly 

 shagreened all over, and. having no supra-basal lateral impressions ; 

 it is clothed with a moderately thick greyish pubescence, and so are 

 the elytra which are oblong, a little broader than the prothorax at 

 its widest part, striate with the intervals convex and very rugose. 

 Length 6^ mm. ; width 3 mm. 



Hab. Zambesia (Salisbury), Mozambique (Quillimane), teste

Allied to D. vidua, Catal., p. 456, but at once distinguished by 

 the much more rugosely shagreened prothorax and elytra ; the intervals 

 of the latter are convex instead of being plane. In his description of 

 what I take to be the present species, Herr Kolbe, in comparing it to
