sutural groove instead of a raised line in the frontal part; it is not 
so spherical as A. emeritus, which is really its nearest ally, and from 
which it is also distinguished by the punctuation of the prothorax 
which is not so closely set, and by the deeply striate dorsal part 
which plainly numbers six striz on each side; the anterior tibie are 
also bi-dentate outwardly. If the genital armatures, which are on 
the same plan, of the two species are compared, it is seen that the 
tubular part is much more deeply notched and twists inwardly 
on the left side in A. laetulus, the right process is sub-horizontal 
and does not therefore act as an operculum, the inner forcipate 
process is very short, and the apical part of the tubular part is 
flattened into two small processes. 
Length 54-64 mm.; width 4-44 mm, 
Hab. Southern Rhodesia (Salisbury). 
ABLABEROIDES FAHRAI, Pér. 
Trochalus eneus, Fahy., Insect. Caffr., 11., p. 131. 
Ovate, reddish-bronze, with the elytra often greener, and with an 
opaline sheen, antennze and palpi flavescent or rufescent, the club 
‘slightly longer than the pedicel in the male; the sharply tri-dentate 
clypeus is not as sinuate laterally as in 7’. emeritus, and the upper 
angle of the lateral constriction is very sharp; instead of a frontal 
suture there is a plainly raised line; the prothorax is of the same 
shape as that of 7. emeritus, but the punctures, although equally 
fine, are not set quite so close to each other, and the intervals in 
the median dorsal part are not sub-strigillate; the elytra are more 
elongato-ovate and appear therefore less convex in proportion, in 
nearly all my examples the four dorsal striz are distinct, and 
as often as not there are plain traces of a fifth and even a sixth; 
interior tibiz bidentate outwardly; this species is easily recognised 
from its congeners by the presence of a raised line instead of a 
grooved suture at the junction of the clypeus with the frontal part, 
but the shape of the genital armature distinguishes it also readily, 
the two claspers being strongly twisted, spatulate at the tip with 
the upper one nearly erect, and the other curving upwards 
underneath. 
Length 53-64 mm. ; width 33-44 mm. 
Fahreeus, in his description of the species, says that the anterior 
tibiz are tri-dentate, and that with the exception of the sutural 
stria which is impressed behind, the striz are hardly visibly striate. 
My examples, compared with the type, are, however, as described 
here.
