T. placens and T. badius, but there is no longitudinal keel; the 
sculpture of the head, prothorax, and elytra is the same as in 
T. placens, from which it is distinguished by the truncate median part 
of the anterior clypeal margin and the much less raised lateral one. 
Length 6-7 mm. 
Hab. Natal, teste Fahreus; Mozambique (Delagoa Bay).

Arch. f. Naturg. xxxiil. 1., 1866, p. 44. 
T. picipes, Fahr., Insect. Caffr., ii., p. 126. 
Dark bronze, turning sometimes to chestnut-red, strongly irides- 
cent, legs reddish, antennee flavescent ; more ampliato-ovate than 
T. badius, and also shorter, but whereas in 7. badius the outer 
margin of the clypeus is plainly connected with the anterior one at 
a distance equi-distant from the centre and the sharp outer angle, in 
T. picipes the outer margin is continued to the edge of the outer 
angle, and the longitudinal keel is moderately conspicuous ; the striz 
on the elytra are hardly distinct except the juxta-sutural one, and 
the punctures on the head, prothorax, and elytra are not so deep as 
in T. badius, but similar to those of T. splendidulus which it 
resembles more than even 7’. badius, except in the shape of the 
clypeus. 
Length 7-8 mm. ; width 5-54 mm. 
Hab. Transvaal (Pretoria, Zoutpansberg, Lydenburg). 
TROCHALUS H#RUGINEUS, Burm., 
Handb. d. Entomol., iv., 2, p. 160. 
T. ferrugineus, Fahr., Ins. Caffr., ii., p. 137. 
Ovate and very convex, elongato-ovate or elongate, either com- 
pletely ferruginous-red or dark bronze, with the head green and the 
elytra reddish, or completely bronze-green, shining, not iridescent, 
antenne flavous; clypeus truncate in front and with the angles 
sharp but not reflexed, the lateral margin is continued as the edge 
of the outer angle, there are no traces of longitudinal keel; the 
punctures in the anterior part are deeper and more rugose than on 
the frontal; the prothorax and elytra are very closely punctate, the 
latter have occasionally one, somewhat faint, stria in addition to the 
juxta-sutural one; the anterior tibie are tri-dentate, but the upper 
tooth is very often merely angular, and disappears also completely. 
The valves of the genital armature are very short, and somewhat 
resemble those of 7. mashunus.
