PEIONOTOLYTTA, n. gen. 
Facies and characters of Cantharis, but differs in the shape of the 
antennal joints which are compressed and with the joints 5-10 as strongly 
serrate fiabellate inwardly as in the genus Eletica. 
Prionotolytta binotata, Pering., 
Trans. S. Afric. Phil. Soc, iv., 1888, p. 139. 
Black, clothed with a very dense, appressed greyish pubescence hiding 
the black teguments, but the prothorax is yellowish red with tw^o black 
macules on the central part, and the colour is not hidden by the greyish 
pubescence which is not so dense there as on the elytra or the under side ; 
head with a frontal small reddish spot ; abdomen reddish ; head very 
closely aciculate and without any central frontal line ; antennae moderately 
long, reaching slightly beyond the shoulders, joints 4-10 triangular with 
the inner upper angle so acute as to give them a pectinate fiabellate 
appearance greatly resembling that of Eletica but sharper inwardly, the 
ultimate joint is swollen in the centre and sharply acuminate ; prothorax 
hardly broader than long, only slightly narrowed laterally at the apex, and 
having thus a somewhat parallel look, there is no distinct- basal impression 
or longitudinal line, and the surface is deeply aciculate punctate ; elytra 
elongated, attenuated from the base which is broader than the prothorax 
to the apex which is of about the same width, the outer margin is sinuated 
past the median part, the surface is finely aciculate, and there are no 
traces of costules ; under side and legs finely aciculate. 
From the appearance of the abdominal segments the only example 
I have as yet met with seems to be a female. 
Length 8 mm. ; width 2 mm.

CYANEOLYTTA, gen. nov. 
Mentum one- third broader than long, transversely hexagonal, ligula 
triangular, dilated, truncate at the upper part, deeply grooved longitudinally 
in the centre, the ligular lobes long, elongate ovate, densely ciliate, maxillae 
robust, the lobes greatly dilated and also densely ciliate ; apical joint of 
palps triangular ; mandibles very robust, transversely curved under the 
labrum and not projecting slantingly beyond it, apical inner part bluntly 
four-dentate at tip ; labrum very broad as long as the epistome, but 
broader ; eyes very large, reniform ; antennae long, second joint small, 
4-11 greatly compressed, longer than broad, dilated at apex ; prothorax 
nearly straight laterally from the base to two -thirds of the length, 
moderately attenuated thence to the apex, base straight not distinctly
