new Longicorn Coleoptera. 507 
In facies generally resembling Sophronica, but its large 
transverse anterior coxe and elevated prosternum on a 
level with them is an important structural peculiarity. 
The setaceous antenne, free of the long hairs charac- 
terising Sophronica, is perhaps less important. 
Corus annulicornis. 
C. robustus, supra subnitide niger; antennis albo-annulatis, 
articulis tertio quartoque conjunctis sequentibus fere longitudine 
equalibus. Long. 4 lin. 
Hab. Grahamstown. 
Stout, moderately glossy, black, slightly pubescent; head and 
prothorax coarsely punctured; antenne much shorter than the 
body, the second and succeeding joints ringed at the apex with 
close-set coarse white hairs; prothorax transverse, a minute spine 
towards the base on each side; scutellum semicircular; elytra 
subeylindrical, rounded at the apex, the surface with large irregular 
but shallow sparsely-punctured depressions; body beneath and legs 
pitehy. 
Pachypeza marginata. 
P. elongata, picea, sparse pubescens; prothorace basi quam 
apice latiore, vitta alba laterali ornata; elytris subparallelis ad 
latera albo-marginatis. Long. 8 lin. 
Hab. Brazil. 
Elongate, pitchy brown, sparsely pubescent; head with two 
fulvous lines in front between the eyes; antenne longer than the 
body, uniformly ciliated beneath; prothorax longer than broad, 
and broader at the base than at the apex, transversely wrinkled, a 
white stripe at the side continued to the eye; scutellum transverse ; 
elytra nearly parallel, closely punctured, and sprinkled with small 
silaceous spots, the outer margin edged with pure white; epi- 
pleura of the meso- and metathorax also pure white and continuous 
with the stripe on the prothorax; body beneath with a fulvous 
pubescence. 
This species differs from P. pennicornis in its shorter 
antenne, uniformly ciliated throughout; its only mode- 
rately compressed and comparatively longer tibie ; and 
coarser punctuation.
