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. 



Hob. Natal, teste Fahraeus; Mozambique (Delagoa Bay). 



Teochalus bohemani, Gerst., 

 Arch. f. Naturg. xxxiii. i., 1866, p. 44. 

 T.picipes, Fahr., Insect. Caffr., ii., p. 126. 



Dark bronze, turning sometimes to chestnut-red, strongly irides- 

 cent, legs reddish, antennae flavescent ; more ampliato-ovate than 

 T. badius, and also shorter, but whereas in T. 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 striae 

 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 T. badius, except in the shape of the 

 clypeus. 



Length 7-8 mm. ; width 5-5^- mm. 



Hab. Transvaal (Pretoria, Zoutpansberg, Lydenburg). 



Trochalus iERUGiNEUS, Burm., 



Handb. d. Entomol., iv., 2, p. 160. 



T. ferruginous, 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, 

 antennae tlavous ; 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 tibiae 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 T. mashunus.
