constricted near apex ; upper surface coarsely punctured, with a very 

 shallow central furrow, transversely impressed near apex and usually 

 with a shallow fovea in the impression on each side of the central 

 furrow. Elytra suboblong, the basal margin shal lowly sinuate and 

 not broader than the base of the thorax, broadest at the shoulders, 

 which are angularly produced, the sides being very gradually 

 narrowed posteriorly ; the posterior declivity very abrupt and 

 angulated dorsally ; upper surface with more or less regular rows 

 of large punctures, almost plane as far as the 4th interval, then 

 sloping sharply to the 6th ; interval 4 costate and with a row of 

 small tubercles as far as the declivity, 6 with a similar row reach- 

 ing the apex, 2 with a short row of tubercles on the declivity only 

 and finally an oblique callus on each side of the base. Legs black, 

 with patches of grey scaling and scattered pale setae ; tibiae more 

 or less scabrose; tarsi comparatively long and slender.

Type in the Stockholm Museum. 



It is doubtful whether this species really occurs in South Africa, 

 for I have seen no properly authenticated modern specimens. 



3. Synthocus sinuatus, sp. nov. 



Long. 6-12 ; lat. (at shoulders) 3J-7J mm. 



Colour black or dark brown above, the inflexed sides and the 

 apical half of the declivity with dense greyish white scaling ; with 

 very few inconspicuous setae. 



Prothorax scarcely longer than broad, sides slightly rounded, 

 shallowly constricted towards apex and very slightly narrowed 

 towards the base ; upper surface coarsely punctured, with a 

 shallow central furrow and on each side a shorter furrow (often 

 indistinct) running obliquely from the middle into the deep sub- 

 apical impression ; sides deeply and rugosely punctured. Elytra 

 suboblong, the basal margin sinuate and not broader than the base 

 of the prothorax, shoulders angularly produced, the sides gradually 

 narrowed to the declivity, which is angulated dorsally and nearly 

 perpendicular ; upper surface almost plane as far as interval 4 and 

 then sloping sharply to interval 6, the disk more or less impressed 

 in the middle, with large shallow and mostly irregular punctures ; 

 the angular 4th interval is curved strongly outwards behind, and 

 forms a prominent blunt angle at the declivity where it overhangs 

 the end of interval 6 ; the latter is less distinctly carinate than usual 

 and scarcely tuberculate except down the sides of the declivity; 

 across the top of the declivity is a low tuberculate ridge, broadly
