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 T. 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 tibiae 

 bi-dentate outwardly. 



Length 7-7J mm. ; width 5-5^ mm. 



Hab. Northern Damaraland, Ovampoland (Humbe). 



Trochalus lucidulus, Burm., 

 Handb. d. EntomoL, iv., 2, p. 161. 

 T. Moris, Fahr., Insect. Caffr., ii., p. 132. 



Ovate, greenish-bronze, shiny, antennae 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 surfa6e 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 striae, somewhat ill- defined with the exception of the 

 juxta-sutural one, and the intervals are plainly punctate ; anterior 

 tibiae bi-dentate outwardly. 



Length 5J mm. ; width 4 mm. 



Hab. Natal (Durban). 



Very like green examples of the short form of T. ferrugineus. I 

 have not seen Burmeister's type, but his description, especially that 

 of the vertex of T. lucidulus, i.e., ''vertex with a double transverse 

 impression," agrees very well with my co-type of T. chloris, Fahr. 

 Burmeister's example was probably also a female. 



Trochalus mashunus, n. spec, 



Plate XLVL, figs. 29, 30. 



Eeddish-brown or chestnut-brown, moderately shiny, more or less 

 strongly iridescent ; antennae 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
