A Bcvision of the Genus Synthocus. 101 



the apex, 2 with a row of tubercles on the dechvity only, and 3 with 

 an indistinct basal callus. Legs with dense brown scaling and dark 

 setse ; tibiae not scabrous, the external apical angle not produced 

 laterally ; tarsi very short and broad.

 Willowmore (Dr. H. Bratms), Fraserberg [S. African Mus.]. 



Type in the Stockholm Museum. 



The comparatively long and narrow thorax, the broad deeply im- 

 pressed elytra and the very short tarsi give this species a very 

 distinctive facies. 



12. Synthocus flavotuberosus, sp. nov. 

 Plate VI., fig. 10. 

 Long. 7J ; lat. 5 mm. 



Colour uniform earthy-brown, with the anterior margin of the 

 pronotum, a lateral patch on each side, and all the tubercles on 

 the elytra covered with orange scaling ; setse sparse and incon- 

 spicuous. 



Prothorax evidently transverse, sides slightly rounded, constricted 

 near apex and a little narrowed towards the base, which is sub- 

 truncate ; upper surface convex posteriorly and with shallow 

 punctures almost hidden by the scaling, near apex a deep transverse 

 impression containing three large fovese ; sides with large scattered 

 punctures. Elytra subglobose, basal margin faintly sinuate and not 

 broader than the base of the prothorax, shoulders almost rectangular 

 and tuberculate, sides evidently narrowed posteriorly from the 

 shoulders, the declivity not abrupt but gradually sloping and rounded 

 dorsally ; upper surface convex, closely and irregularly punctured 

 throughout, each elytron with three rows of rounded remote orange 

 tubercles ; the inner row" containing 6 or 7 tubercles and extending 

 from base to apex, the median row abbreviated apically and contain- 

 ing 3 or 4 tubercles, the outer row (on the dorsal margin) complete 

 and containing 6 or 7 tubercles, including two close together at the 

 humeral angle ; inflexed margins with more or less irregular rows 

 of comparatively small punctures. Legs dark brown, with a few 

 paler patches and long white setse ; tibige not scabrous, the outer 

 apical acutely produced ; tarsi comparatively long and slender, the 

 second joint of the posterior pair subquadrate.

I have seen only a single example of this striking species.
