Species of Cavabidee from South Africa. 31 
the shoulder to a very short distance below it ; the posterior 
end of submedian patch squarely truncate. 
Head deeply, sub-confluently punctate ; epistome and 
labrum smooth, shiny. Antenne slender, elongate, filiform. 
Prothorax transverse, apical angles broadly rounded, 
lateral margins widely grooved and reflexed, straight but a 
little inclining inwards to posterior angles which are right 
and moderately sharp, apex emarginate, base produced, 
dise rugosely punctate, convex, median line broadly and 
deeply grooved, reaching from near apex to the transverse 
basal depression. 
Elytra elongate-ovate, shoulders rounded, gently ampliate 
to below middle, slightly contracted to outer angle, and then 
sinuately truncate to apex, narrowly and shallowly striate, 
hardly perceptibly or not punctate, intervals plane, smooth, 
and shiny. 
Beneath shiny and aciculate. 
Hab. Coast bush about Durban. Common. 
Lebia durbanensis, race malvernensis, mihi. 
A local variety of above which shows some consistently 
divergent characteristics, which, I think, justify its bearing a 
distinctive name. 
Shape and size as in durbanensis, but differentiated from 
it as follows :—-Puncturation of head and transverse plication 
of prothorax coarser and deeper, the coloration of the 
latter rufescent, more or less darkened centrally ;_ strice 
of the elytra deeper and distinctly transversely punctate, 
intervals a little raised (in typical durbanensis they are 
quite plane). The pattern is the same, but less developed, 
the submedian patch being usually separated from the sub- 
marginal band by a considerable interval of the ground- 
colour. ‘The pygidium is pale reddish instead of piceous, 
aud all my examples have conspicuously developed tubercles 
at their outer angles, which are wanting in both sexes of 
the numerous examples of durbanensis that I have examined. 
The colour beneath and of legs is paler and the integument 
smoother, aciculation only being visible in the strongest 
hghts. 
Hab. Malvern, Natal. Common under bark. 
Specimens of these two races of durbanensis have been 
compared for me with the type of L. insidiosa, Pér., which 
is in the British Museum (Nat. Hist.) by my friend Dr. 
G. A. K. Marshall, who pronounces them as quite distinct 
from that species. L. insidiosa was originally described by
