in front, that is to say not dentate in the median part of the 
anterior margin, and having a median somewhat short, longitudinal 
keel, the lateral margins are moderately sinuate and are continued 
inwardly to a short distance from the anterior angle, and abut nearly 
on the reflexed anterior margin ; prothorax of the usual shape, and 
deeply punctate; scutellum normal and closely punctate ; elytra 
elongato-ovate, faintly striate except in the posterior part where the 
striz, especially the lateral ones, are a little more distinct, but 
the two supra-marginal ones are distinct from base to apex, the 
intervals are coarsely punctured. I have not seen the male of 
this species. 
Length 84-10 mm.; width 6-64 mm. 
Hab. Ovampoland. 
TROCHALUS PLACENS, n. spec. 
Reddish-brown, ampliato-ovate, convex and very shiny, antennz 
rufescent ; shorter and more amphate than 7’. badius, and resembling 
greatly T. fulgidus ; the clypeus is strongly keeled longitudinally, 
very narrowed in front, and the outer angles are as much rounded 
as in that species, but the anterior median part projects a little, and 
the lateral margin which is very strongly raised above the lateral 
constricted part, slants thence towards the anterior one which it 
reaches at a short distance from the rounded outer angle in the 
manner of 7’. badius, but in the latter the lateral margin is not 
strongly sinuate, nor is it as much raised as in 7’. placens, and the 
punctures, although deep, are not so coarse. The shape of the lateral 
margin of the clypeus greatly resembles that of J. modestus, but in 
this species, which is much less ampliato-ovate, it does not reach the 
anterior edge.

TROCHALUS FULGIDUS, Fahr.,

? T. splendidulus, Fahr., loc. cit., p. 129. 
Strongly ovate, chestnut-red, or dark bronze, shiny, moderately 
iridescent; antennze rufescent; clypeus very narrow, straight in 
front but with the outer angles rounded, the lateral margin is only 
moderately raised above the lateral constriction and produced thence 
towards the anterior margin, which it reaches at a short distance 
from the rounded outer angle, much in the same manner as in
