higher level than the genal canthus, broadly separated from it, and 

 very distinct, there is a frontal arcuate suture, the clypeal part which 

 is very faintly depressed close to the anterior margin is scrobiculato- 

 punctate, the frontal moderately closely punctate ; prothorax much 

 broader at the base than at the apex, convex, faintly bi-impressed near 

 the basal margin, closely punctate, but the punctures are hidden by 

 the silky opaque indumentum ; scutellum sharp, punctate ; elytra 

 very plainly ampliated towards the posterior part, short, very convex 

 and having on each side seven very plain striae with the intervals 

 slightly convex in the posterior part ; anterior tibiae bi-dentate, 

 posterior ones broadly dilated inwardly, basal joint of hind tarsi 

 slightly shorter than the second, and also shorter than the hind 

 spurs. 



Length 4-5 mm. ; width 2f-3J mm. 



Hab. Natal (Durban). 



DOLEROSERICA GENTILIS, n. spec. 



Chiefly allied to D. curtula, from which it differs by the more 

 deeply notched anterior margin of the clypeus and the non-opaque 

 upper part of the body which is bronze, moderately shining and 

 faintly iridescent in the posterior part of the elytra, the latter part is 

 striate in the dorsal part only, and not as ampliated behind as in 

 D. curtula. 



Length 5 mm. ; width 3J mm. 



Hab. Natal (Newcastle). 



DOLEROSERICA LAETULA, n. Spec. 



Bronze-red, quite opaque and sericeous on the upper surface, 

 shiny and iridescent underneath ; antennae ferruginous-red ; clypeus 

 not at all constricted or sinuate laterally, straight at apex with the 

 outer angles slightly rounded, the margin is moderately reflexed and 

 not angular in the centre, genal keel strongly projecting, anterior 

 part scrobiculate, frontal deeply punctate, but not along the base, 

 frontal suture slightly bi-sinuate ; prothorax sub-arcuate laterally, 

 much broader at the base than at the apex, somewhat closely punc- 

 tate, and having above the median part of the base a long, transverse 

 impressed line ; scutellum punctulate ; elytra ovate, convex in the 

 anterior part, striate on the dorsal and sides but not near the humeral 

 lateral part, intervals moderately closely punctate ; basal joint of 

 hind tarsi nearly as long as the following one. 



The shape of the head is almost similar to that of the species of 

 Autoserica.
