points, other large punctures behind the transverse striz are 
confluent, transverse stria straight and well marked; the 
thorax, marginal stria complete and raised laterally, punctu- 
late on the disk, but outside the central area the points are 
larger and clearer, somewhat dense, with a few fine points 
interspersed, along the base is an irregular line of the larger 
points; the elytra—striz, outer humeral dimidiate, internal 
complete and very similar to the first stria, 1-4 complete, 5 
abbreviated before the base, sutural apical and dimidiate, 
interstices finely punctulate, with a band of larger points 
along the posterior margin; the propygidium closely, not 
densely punctured, with the posterior margin feebly raised ; 
the pygidium, punctures larger and deeper than those of the 
propygidium, and the external rim is manifestly elevated ; 
the prosternum without strie, keel feebly punctulate, anterior 
lobe distinctly punctate ; the mesosternum sparsely punctu- 
late, widely, not deeply emarginate, stria complete but ends 
at the metasternal suture; the anterior tibize 4-dentate. 
The dense surface-sculpture of the forehead gives a similar 
appearance of opacity to that seen in A. Schaumt, Mars., but 
there the similarity ends. 
Hab. Cameroon. 
FPlatysoma extrarium, sp. n. 
Oblongum, subcylindricum, nigrum, nitidum; fronte punctulata, 
stria integra tenuiter impressa; thorace stria integra necnon 
basi conspicue continuata; elytris striis 1-4 integris, 5 apicali 
dimidiata; pygidio basi punctata, apice leevi. 
ej mill: 
Oblong, somewhat cylindrical, black, shining; the head 
anteriorly impressed, surface finely punctulate, stria complete 
but very fine anteriorly, where it crosses the impressed area ; 
the thorax, anterior angles somewhat produced, surface 
microscopically punctulate, lateral rim carinate and joins the 
lateral stria behind the eyes, lateral stria complete anteriorly 
and posteriorly, before the scutellum there is a distinct oval 
fovea in front of the basal line ; the elytra at their bases have 
a corresponding stria to the Lasal thoracic one, but it is not 
quite so deep and it is carried along the lateral border of the 
elytra as an inner epipleural stria, there is a fine oblique 
basal humeral line, strie 1-4 are complete with crenulate 
edges, 5 apical and dimidiate, sutural wanting; the propy- 
gidium is irregularly punctured, punctures for the most part 
not circular in outline, the basal margin and a small triangular 
median basal space smooth; the pygidium is punctured at
