discoidal impression reaching from the median part to the anterior 

 margin which bears a small tubercle in the centre, and it is covered 

 on the sides with somewhat broad but closely set punctures having 

 scabrose intervals, but the punctures in the median impression are 

 not very closely set, and the intervals are smooth ; scutellum not 

 very distinctly punctured ; elytra deeply punctured, the punctures 

 are equi-distant, and along the basal part, the intervals are slightly 

 raised ; pygidium covered with equi-distant foveolate, shallow 

 punctures separated by a narrow interval ; abdomen with squamose 

 hairs laterally, not depressed in the centre, penultimate segment 

 nearly twice as broad as the one preceding, ultimate one broad and 

 convex ; pectus without pubescence; anterior tibiae tri-dentate, basal 

 tooth very short ; all the tarsi are missing in the only example I 

 have seen, and which closely resembles E. montana, Brsk. 



Length 12 mm. ; width 5± mm. 



Hab. Southern Ehodesia (Mashunaland). 



HOLISONYCHA, n. gen. 



Mentum strongly incised laterally near the ligular part, and very 

 sharp at apex, labial palpi inserted laterally, the other buccal organs 

 as in Schizonycha ; the antennal club of the male is as long as the 

 pedicel the joints of which, with the exception of the two basal 

 ones, are very small and closely set, the third being hardly longer 

 than the fourth; the head and body are those of Schizonycha, but 

 the long and slender claws are not much curved, and are simple at 

 the tip. 



HOLISONYCHA MELLILA, n. Spec. 



Light brick-red, or pale testaceous, shining, each puncture on the 

 upper side with a most minute hair ; head small, clypeus truncate 

 with the outer angles rounded, hardly emarginate in the centre, clypeal 

 carina very slightly arcuate, suture indistinct, basal carina distinct, 

 slightly sinuate in the middle ; clypeal surface covered with irregular 

 punctures having raised intervals, frontal surface plainly granulose ; 

 prothorax not much ampliated laterally towards the median part, 

 and attenuated thence to the basal angle which is distinct, but not 

 very sharp, outer margin somewhat crenulate in the posterior part, 

 and ciliate, surface covered with round, scattered punctures 

 separated by smooth intervals, the punctures are more closely set on 

 the sides and along the anterior margin ; scutellum impunctate ; elytra 

 elongated, cylindrical, the punctures somewhat apart ; pygidium 

 not distinctly punctate ; abdominal segments not deeply punctate
