protliorax convex, sub-parallel laterally with the base arcuate ; elytra 

 convex, rounded laterally, narrowly striate with the striae carinate 

 on each side and having a supra-marginal carina slightly overhanging 

 the marginal one, epipleura broad ; pygidium vertical ; nietasternuni 

 separated from the prosternum in the middle by a sub-arcuate trans- 

 verse raised line ; prosternum moderately broad but not quite as 

 much as in EpilissuH ; anterior tibiae strongly dilated at apex and 

 having two blunt teeth set close together, and a strong one at tip 

 nearly at right angles with the apical part which is straight and has 

 at the apex of the inner part a short curved spur slightly directed 

 downvvards ; intermediate and posterior legs compressed, a little 

 dilated at tip ; the two apical spurs of the intermediate tibiae are 

 not very long but are distinct nevertheless, and the posterior ones

 pressed, basal joint shorter than the others. 



Odontoloina are small convex insects found sometimes in decaying

 whitish bristles which are arranged regularly at some distance from 

 one another on the elytra. 



Three species are recorded from South Africa, and have not as 

 yet been met with elsewhere.
