very close to the basal part of the strongly reflexed outer angle, in 
T. damarus they are connected with the central part of the reflexed 
anterior margin; the longitudinal keel is almost obliterated, and the 
frontal part is scrobiculate instead of being punctate as in 7. vagus, 
the punctures on the elytra are also deeper; in the female the basal 
groove on the vertex is not so deep as in the male; anterior tibie 
bi-dentate outwardly. 
Length 7-74 mm. ; width 5-5} mm. 
Hab. Northern Damaraland, Ovampoland (Humbe). 
TROCHALUS LUCIDULUS, Burm., 
Handb. d. Entomol., iv., 2, p. 161. 
T. chloris, Fahr., Insect. Caffr., ii., p. 182. 
Ovate, greenish-bronze, shiny, antennze flavous ; clypeus normally 
constricted laterally, with the lateral margin continued as the edge 
of the reflexed but not projecting outer angle, anterior margin 
angular, but not sharply dentate in the centre, there is a very 
faint, longitudinal raised part which, however, is not keeled, and 
running parallel to the base and equi-distant from the base and the 
transverse frontal keel there is a transverse, moderately shallow 
groove which does not reach the sides, the surface of the clypeal 
and of the anterior frontal parts is deeply and roughly punctate; the 
punctures on the prothorax are fine and closely set; the elytra have 
four dorsal striz, somewhat ill-defined with the exception of the 
juxta-sutural one, and the intervals are plainly punctate ; anterior 
tibize bi-dentate outwardly. 
Length 54 mm.; width 4 mm. 
Hab. Natal (Durban). 
Very like green examples of the short form of 7. ferrugineus. I 
have not seen Burmeistev’s type, but his description, especially that 
of the vertex of 7. lucidulus, 7.e., ‘‘ vertex with a double transverse 
impression,” agrees very well with my co-type of 7’. chloris, Fahy. 
Burmeister’s example was probably also a female. 
TROCHALUS MASHUNUS, N. Spec., 
Plate XLVL, figs. 29, 30. 
Reddish-brown or chestnut-brown, moderately shiny, more or less 
strongly iridescent; antenne flavescent; body massive, not 
spherical, clypeus strongly narrowed laterally, very sharply tri- 
dentate in front, and with the strongly sinuated lateral margin 
almost dentate above the narrowed anterior part, and meeting the
