six impressions similar bnt shallower ; the recumbent setse 

 about twice as long. Elytra more regularly oblong, the 

 shoulders well marked but without any humeral prominence, 

 no projection on interval 9 behind the shoulder, and the 

 apices jointly rounded ; the alternate intervals slightly and 

 more or less evenly costate, without tubercles behind, except 

 for a low prominence at the apex of interval 5 ; the scales 

 much larger and flat, the setae nearly twice as long, being 

 much more numerous on the raised intervals than on the 

 others. 



Length 3"2-4'4 mm., breadth 1*4-2 mm. 



Cape Province : Willowmore [Dr. H. Brauns). 



Described from 113 specimens. 



Gronops oneilt^ sp. n. 



(^ 5^ . Integument black, with dense sandy or earth-brown 

 scaling, wath a broad darker transverse band behind the 

 middle ; the posterior pairs of femora and tibiae each with 

 two dark brown patches ; the apical area of the rostrum 

 with small convex greenish-white scales. 



Head with the scales flat and contiguous, not overlapping; 

 the supraocular ridges comparatively low, sloping behind, 

 and hardly reaching the hind margin of the eye. Rostrum 

 parallel-sided from the base to the antennae, the apical area 

 being slightly wider; the dorsal outline distinctly angulated 

 at the insertion of the antennae ; the posterior angle of the 

 lower edge of the scrobe produced backwards into a blunt 

 projection ; the dorsum rounded at the sides, with a narrow 

 shallow median furrow and two indistinct strife on either 

 side, each containing a row of recumbent setae, and there is 

 an additional dorsal row on each side ; when abraded the 

 surface is very rugosely punctate. Prothorax with the sides 

 strongly rounded in front, broadest much before the middle, 

 and gradually narrowed from there to the base, the sides 

 being almost straight in the basal half; the dorsum with a 

 broad median furrow and two deep impressions on each side 

 of it; the raised areas with very deep scattered punctures, 

 each containing a short seta, the setae l)eing much finer than 

 those on the rostrum or elytra; the scales small, not im- 

 pressed, and hardly overlapping. Scutellum small, but 

 prominent. Elytra diff'ering from those of the two pre- 

 ceding species in being relatively broader, slightly rounded 

 at the sides, and gently convex longitudinally ; the shoulders 

 with a rounded humeral prominence, but none on interval 

 9, the apices joiutiy rounded ; the punctures in the striae
