having in addition a supra-marginal costule, they are finely coriaceous, 

 and very densely hairy, but these hairs are sometimes wanting on the 

 costge at regular intervals, and gives thus to the elytra a sub-tessellated 

 appearance ; pygidium broad, vertical in both sexes. 



In the male the slightly squamulose hairs are denser than in the 

 female, and the latter has an apical spur to all the legs. 



Length 8 mm. ; width 9 mm. 



Hah. Cape Colony (Port St. John, Kowie), Natal (Durban). 



CONGELLA MASHUNENSIS, U. SpeC. 



Male : Colour, sculpture, and vestiture of G. tessellata ; the head 

 and clypeus are similar, but the prothorax is more angular laterally 

 at middle and more obliquely attenuated thence towards the basal 

 angle ; the elytra are much more plainly tri-costate on each side, 

 ai:id the intervals are deeper, but the minute scale-like hairs are 

 identical. 



Length 9 mm. ; width 5 mm. 



Hab. Southern Ehodesia (Salisbury). 



CONGELLA VALIDA, n. speC. 



Eeddish brown, sometimes slightly infuscate ; head with scattered 

 granules, clypeus parabolic but a little blunt at the tip ; prothorax as 

 in the preceding species, but the space among the scar-like punc- 

 tures are plainly wrinkled or rugose ; the elytra are similarly costate, 

 the hairs are not so dense, but longer and less squamulose, and 

 the sculpture consists of contiguous impressed punctures having in 

 the centre a smaller one emitting a hair ; these hairs are similar 

 on the upper and under sides and also on the legs as well as on the 

 pygidium, the latter is granulose and has a median longitudinal 

 furrow ; in the male the legs have no apical spur, but in the female 

 the four posterior legs are provided with one. 



Length 11-12^ mm. ; width 6|^ mm. 



This species is much more massive than C. tessellatida, and the 

 vestiture is not much denser in the male than in the female. 



CONGELLA NIGBITA, n. speC. 



Intermediate in size betw^een C. tessellatula and C. valida ; the 

 colour is black on the upper side, pieeous red underneath, and 

 the prothorax and elytra bear minute, scattered, greyish appressed 

 hairs ; the shape and sculpture of the head are the same as in 

 C. valida, but on the prothorax the cicatricose punctures are deeper;
