44 Mr. C. N. Barker on new 
Simulatorius is differentiated from its very near relative 
C. piceus, Boh., on the following points. It is smaller, very 
shiny in the male and subopaque in the female ; piceus is 
opaque in both sexes. Prothorax is narrower (2+ mm. long 
to 24 mm. wide, as against piceuws 3 mm. long by 4 mm. 
wide), less ampliate below frontal angles, which are sharper, 
and the margins immediately above the hind angles are 
more broadly sinuately reflexed. The puncturation on the 
centre of the disc is sparser and less evenly distributed, the 
median groove is also shorter and deeper. 
On the under surface the puncturation of the sternal 
parts is coarser and the venter is aciculated or punctulated 
over the whole surface, in piceus the centre part is quite 
smooth. 
The pubescence also appears to be denser and longer, but 
this may perhaps be due to being fresher specimens. 
Described from three examples, one male and two females, 
taken by me in bush among damp leaves and detritus, 
November 1902. 
Hab. Mouth of Ifafa River, Natal. 
Chlenius obliquatus, sp. n. 
Length, male 11? mm., female 12-123 mm. 
Black, shining, in both sexes ; antennz, palpi, and legs 
red, the basal joints of the two first-named a shade lighter. 
Head very finely and densely aciculate-punctate, a little 
plicate on either side frontally ; antennz medium length, 
joints above third basal widened and compressed. Pro- 
thorax very transverse (males 3 mm. long by 4 mm. wide, 
females a little wider), widest at base, apex emarginate, its 
aneles produced but not sharp, sides for a short distance 
below apices, males roundly, females more _ obliquely 
ampliated, thence continued straightly to posterior angles, 
which are obtuse ; base shallowly and broadly emarginate 
medially, disc plane, declivous frontally, densely punctate, 
median line and lateral foveze shallow and not very con- 
spicuous. 
Elytra at base hardly wider than prothorax, oblong-ovate, 
a little narrower in male than in female, apices rounded, 
very declivous, briefly pubescent laterally and apically, 
deeply striate, intervals raised and more or less irregularly 
punctate all over. 
A near ally of C. trapezicollis, Chd., from which it differs 
in its larger size, more transverse shape, denser and finer 
puncturation of head and prothorax, and in the marked 
ss. because
