tlie mid and hind coxry is shorter than the mid-coxa, whereas 

 iu Grojiops it is much longer. 



Genotype, Gronops proletarius. Boh. 



Notogronops estriatus, sp. n. 



^ . Integument black, with dense scaling ; the whole 

 upper surface dull smoky black ; the lower surface grey, 

 with a large oblong blackish-brown patch occupying the 

 middle of the metasternum and of the first two ventrites. 



Head convex, with a very shallow transverse impression 

 before the base of the rostrum ; the scales flat, not over- 

 lapping, with sparse, short, stout, recumbent setse. Rostrum 

 almost straight, a little shorter than the median length of 

 the pronotum (8:9), very slightly narrowed from the base 

 to the antennpe and then abruptly widened; the dorsum 

 transversely convex, without sulci or carinte, the basal half 

 clothed like the head, the interantennal area without scales, 

 but with dense curled setse ; the geuae with dark scaling and 

 long, stiff, black setae. Antenna red-brown ; joint 2 of the 

 funicle nearly as long as the next two together. Prothorax 

 a little longer than the basal width (9 : 8), slightly widening 

 from base to apex, the sides almost straight, the postocular 

 lobes very prominent ; the dorsum convex in both directions, 

 highest near the base and sloping strongly in front, with a 

 deep median furrow from the base nearly to the apex, but 

 no lateral impressions ; the strong reticulate punctures 

 normally hidden by the dense scaling, and with sparse, stout, 

 recumbent setse. Elytra narrowly ovate, broadest at about 

 one-fourth from the base, the basal margin deeply sinuate, 

 the apices jointly rounded, without any striee or rows of 

 punctures even when the scaling is removed, but the first 

 and alternate intervals represented by rows of stout recum- 

 bent setse, which are dark and larger on the disk and pale 

 and smaller at the sides ; intervals 3 and 5 shortly costate 

 at the base. Legs densely clothed with pale scaling, the 

 femora with a dark patch in the middle and another near 

 the apex, the tibise with one at the base and one at the 

 middle; the femora with dense pale setae beneath. 



Length 4 mm., breadth 1'6 mm. 



Cape Province : Algoa Bay, 26. vii. 1896 (Dr. H. Braims). 



Described from a single specimen. 



Easily distinguished from the other described species of 

 the genus by its unusual colouring and by the absence of the 

 lateral impressions on the prothorax and of the punctures on 

 the elytra.
