almost concealed by the scaling ; the intervals almost flat, 

 each bearing a row of short spatulate suberect pale set.Te ; 

 the scales oval, more or less contiguous, but not overlapping. 

 Legs rufescent, with dense pale scaling.

Orange Free State : Bloemfontein, iv. 1918, on grass. 



Described from six specimens forwarded by the Division 

 of Entomology, Pretoria. 



Distinguished from all the previously described species of 

 the genus by its very small size, the broadly exposed rostral 

 scrobes, and the parallel-sided interantennal area. 



Genus Euonychus, nom. nov. 



Euom/.T, Marshall (nee Norman, 1867), Ann. & Mag. Nat. Hist. (8) i. 

 1908, p. 19. 



Unfortunately the generic name Euo?iyx, Norm., was 

 inadvertently omitted from Scudder's ' Nomenclator,^ 

 so that I was not aware of its having been used previously 

 when this genus was described, and a new name is therefore 

 now proposed for it. 



The discovery of a second species renders necessary a 

 modification of some of the generic chaiacters. The 

 apical dilatation of the rostrum in the genotype, E. sulci- 

 rostris, Mshl., is clearly of specific value only ; and in the 

 new species the rostrum is not entirely continuous with 

 the forehead, for there is a shallow transverse furrow 

 separating them in the middle, which does not reach the 

 lateral margins and is sometimes almost obliterated by the 

 scaling. 



Euonychus bivlttatus, sp. n. (PI. V. fig. 7.) 



^ $ . Integument black, densely clothed with scaling, 

 which on the whole lower surface, legs, and inflexed margins 

 of the elytra up to stria 6 is grey, usuallj^ with a pinkish 

 reflection ; the head and rostrum with mingled brown and 

 grey scales ; the dorsum of the prothorax and elytra dark 

 brown (in S ) with two grey stripes starting at the apex 

 of the prothorax and continued along interval 3 of each 

 elytron to well behind the middle ; interval 2 with grey 

 scaling for a short distance at the base, intervals 4 and 5 

 with a few variable grey flecks, and the declivity either 

 brown mottled with grey or vice versa. In the $ the 

 brown of the upper surface is lighter and the pale markings 

 are therefore less conspicuous.
