new Cuvculionidse /ro»t South Africa, 153 



small but deep, quite regular, and not geminate; the suture 

 and the alternate intervals more raised, interval 3 more 

 strongly costate than the others behind the middle and with 

 a callus at its base, and interval 5 ending in a small sharp 

 tubercle on the declivity ; the scales flat and only slightly 

 overlapping, the raised intervals alone having a row of 

 large, scale-like, recumbent setae. Sternum entirely lacking 

 the prosternal impression. 



Length 2*6-3'2 mm., breadth l'4-l'6mm.

Described from three specimens. 



Readily distinguished from the other two species by its 

 small size and more convex form, the characteristic scaling 

 at the apex of the rostrum, the form of the scrobe, and by 

 the absence of the prosternal furrow. In his key to the 

 Rhytirrhinides Lacordaire erroneously separates Gronops 

 from Hypocolobus and Borborocoetes on the ground that 

 joint 7 of the funicle is annexed to the club in the latter, 

 but not in the former, although in his description of Gronops 

 he correctly states that this joint is contiguous to the club. 

 For this character should be substituted one drawn from the 

 epistome, which is sharply defined and bounded behind by a 

 high carina in Hypocolobus and Borborocoites (sometimes 

 modified into a short horn in the former genus), whereas in 

 Gronops and its allies there is no trace of a carina and the 

 epistome is quite undefined. The three species described 

 above are the only true Gronops known to me from South 

 Africa. 



Genus Notogronops, nov. 



Schonherr (Gen. Cure. vi. 2, p. 135) divided Gronops into 

 two sections : the first, which includes the genotype, 

 G. lunatuSy F., is characterised by its oblong elytra and 

 angulate shoulders, while in the second the elytra are ovate 

 and without any humeral callus. In the second group he 

 placed three South- African species — proletarius, Boh., 

 pimctirostris, Boh,, and squalidus. Boh. I am acquainted 

 with the first and third of these (the type of the second is 

 lost, but the description suggests that it was perhaps only 

 an abraded specimen oi proletarius), and it is clear tliat they 

 cannot satisfactorily be retained in Gronops ; for, apart from 

 the difference in the form of the elytra and the absence of 

 the shoulders, they differ in having joint 7 of the funicle 

 quite distinct from the club, and the metasternum between
