EURONYCHA RHODESIANA, 0. spec.

EuRONYCHA MODESTA, Péring., 
Trans. §. Afric. Philos. Soc., vol vi., 1892, p. 36. 
Female : Testaceous, with the head and prothorax redder, covered 
like the two preceding species with short appressed hairs, not suffi- 
ciently dense, however, to impart to it a sericeous appearance ; the 
whole shape is more elongato-ovate, the head is scrobiculate all 
over ; the punctures on the prothorax and elytra are deep and very 
plain, the latter deeply striate ; the under side is clothed with very 
dense, short, appressed hairs, and the abdominal segments have 
a long lateral pubescence ; anterior tibize strongly tri-dentate out- 
wardly, the two spurs of the hind tibie are of equal length and only 
one-third shorter than the basal tarsal joint. 
Length 9 mm.; width 4 mm. 
Hab. Ovampoland (Omrramba). 
EURONYCHA SEBAKUANA, Nn. Spec. 
Fuscous brown or light chestnut-red ; shape of the larger examples 
of H. sericea, and with a similar vestiture; it is easily separated, 
however, owing to the great length of the basal joint of the hind 
tarsi, which in the male is plainly twice as long as the second, 
and the very short spurs of the hind tibie; in the female this 
basal joint is only one-third as long as the second, but the spurs are 
as short as in the male. 
Length 6-65 mm. ; width 34-4 mm. 
Hab. Southern Rhodesia (Sebakwe).
