(The following genus and species are unknown to me. I have not 

 been able to find the locality " Sissanto " in South Africa, and it is 

 thus possible that it is north of the South African area.) 



Gen. DEEPANOGNATHUS, Lansb., 

 Notes from the Leyden Museum, vol. viii., 1886, p. 92. 



" There is in the Leyden Museum a curious small Orphnid beetle^ 

 remarkable owing to its depressed facies and its short clypeus. It 

 cannot be interpolated in any of the known genera, and must form a 

 new one, the distinctive characters of which are as follows : — 



Antennae ten- jointed, basal joint very long, clava lenticular ; clypeus 

 very short ; labrum uncovered, horny, broadly emarginate, rounded 

 laterally and bearing long setae ; mandibles robust, projecting much 

 beyond the head, rounded outwardly, falciform, and enclosing an 

 empty space ; maxillae horny ; mentum moderately elongate, ligula 

 sinuate at tip ; labial palpi short ; apical joint of maxillary palpi 

 very long and fusiform ; coxae oblique, contiguous at the base ; 

 abdominal segments mobile, but not entirely free ; legs of Orphnus, 

 apical spurs of posterior tibiae very long. Facies of a Hydrophilid 

 beetle." ~

 Loc. cit., p. 92. 



" Oblongo-ovate, plane, very shining, black on the upper side, with 

 the lateral part of the clypeus and of the elytra somewhat trans- 

 parent brown, brown also beneath, abdomen testaceo-fulvous ; sides 

 of the prothorax, legs and pectus fringed with long, stiff hairs ; head 

 smooth, transversely impressed in the centre, clypeus very short, 

 straight in front, not refiexed ; eyes very large, no genae ; prothorax 

 reflexed at base, covered with big, remote punctures less numerous
