tures. The elytra are more distinctly ovoid in shape, with 
shoulders more obliterated and interstices more convex, 
more shining, and without microsculpture. The lower side 
has less, but coarser, punctation; the prosternal process is 
less acute at tip; the meso-episterna are smooth; and the 
meta-episterna are shorter, not longer, than wide. Finally, 
the last segment of the labial palpi is less dilated than in 
any other form of the genus, that of the maxillary palpi 
being simple. The aedeagus is different too. 
Chlaenius (Platychlaenius) uzungwensis n. sp. 
Length 13 mm. Head and prothorax reddish brown, the 
latter a little lighter ; elytra black, scutellum reddish ; lower 
side of head and prosternum reddish brown, other sterna 
and abdomen black ; legs and antennae dark ferrugineous. 
Head long, with very fine punctation, chiefly on disk, 
nearly obliterated on vertex; eyes large and prominent, 
temples short, faintly narrowed posteriorly; anterior mar- 
gin of labrum barely concave ; antennae long, barely exceed- 
ing basal third of elytra, 3rd segment much longer than 4th. 
Prothorax nearly as long as wide, faintly convex; an- 
terior margin weakly emarginate; anterior angles prom- 
inent, broadly rounded at tips; sides gently rounded, not 
more narrowed posteriorly; greatest width a little before 
middle ; posterior angles blunt, widely rounded at tips ; base 
faintly concave, as wide as anterior margin, not emarginate ; 
median line fine, superficial, reaching neither anterior mar- 
gin nor base; marginal gutters strongly widened posteriorly 
where sides are broadly explanate and slightly elevated; 
basal foveae very broad ; upper surface with roundish, rather 
large but not very deep punctures, very numerous at sides 
especially near posterior angles, more widely spaced on disk ; 
each puncture with a long, yellowish white seta; anterior 
lateral setae missing, posterior ones before angles. 
Elytra sub-ovate, weakly convex; greatest width behind 
middle; shoulders rounded; apical truncation oblique, indis- 
tinctly sinuate; striae fine but rather deep, not very dis- 
tinctly punctured, the scutellar one long; intervals weakly
