Oxythyrea hamorrhoidalis, Fabr. 



A variety is very common around Pretoria in which the 

 ground-colour of the elytra is shining bluish, and not green ; 

 a scarcer variety is found in which the colour is rosy red. 



Rhabdotis aulica, Oliv. 



I took a variety of this species in which the upper surface is 

 rosy red, not green. 



SERRICORNIA. 



Both Buprestidse and Elateridse are very scarce at Pretoria, 

 the bare plains being apparently uncongenial habitats for the 

 group. Still the largest and handsomest species of the Trans- 

 vaal Buprestidae (Sternocera orissa, var.) is found on the few 

 scattered Acacias which are thinly distributed on the veld, as 

 before described (ante, p. 91). 



Elateridse are probably much more numerous, and the few 

 species here enumerated give little idea of this Coleopterous 

 family as found even on the high veld. 



My best thanks are due to Dr. Caudeze, of Liege, for his 

 determination of these obscure Elaters.
