Type in the Stockholm Museum. 



Closely allied to truncatus, Boh., from which it differs chiefly in its 

 non-angulated thorax, and in the projection of the basal angles of the 

 elytra beyond the base of the thorax. 



5. Synthocus damarensis, sp. nov. 



Long. 6f-8f ; lat. 5-6^ mm. 



Colour of type deep red above, variegated with orange ; elytra 

 with a small elongate velvet-black on each side of the suture about 

 middle ; underparts brown, the leg dull black with sparse white 

 setae. The co-type is entirely earthy-brown, except for the sutural 

 black patches. 



Prothorax scarcely broader than long, the sides bluntly angulated, 

 evidently constricted towards apex, and slightly narrowed at the 

 base ; upper surface rugosely punctured, somewhat convex posteriorly, 

 with a deep transverse impression near apex and a shallow central 

 furrow ; sides with large uneven punctures. Elytra subquadrate, 

 the basal margin faintly sinuate and not broader than the base of the 

 prothorax, shoulders acutely produced laterally, the sides gradually 

 narrowed as far as the declivity, which is very abrupt and angular 

 dorsally ; upper surface quite plane as far as the 4th interval, then 

 sloping sharply to the 6th, set with large punctures which are regular 

 only near the suture ; interval 4 with a row of low tubercles ending 

 at the declivity, 6 with a row of larger tubercles extending to the 

 apex, 2 with a solitary conical tubercle at the top of the declivity, 

 3 and 5 each with an oblique basal callus. Legs brown or black, 

 with sparse white setae; tibiae not scabrous, the external apical angle 

 slightly produced ; tarsi moderately long and thick. 



Damaealand (Andersson and De Vylder). 



Type in the Oxford Museum. 



This species resembles truncatus, Boh., in general facies, and 

 differs from it chiefly in its contiguous intermediate coxae, its 

 broader thorax and much thicker tarsi, and the absence of the 

 median tubercles on the declivity. The only co-type is in the 

 Stockholm Museum. 



6. Synthocus acuticollis, sp. nov. 

 Plate VI., fig. 8. 

 Long llf ; lat. 7 mm. 



Colour earthy-brown, with the following faint grey markings : a 

 broad lateral stripe on each side of the prothorax, an ill-defined spot 

 near the base of each elytron, and a transverse band at the apex of 

 the disk ; setae extremely short and inconspicuous.
