540 Dr. Malcolm Cameron’s descriptions of 
Thorax oviform, not bordered at the sides, very sparingly and finely 
punctured, with silvery pubescence. Scutellum red. LHlytra 
parallel, a little broader and one third longer than the thorax, 
puncturation rather fine, squamous as in variicornis, rather densely 
clothed with silvery pubescence. Abdomen finely and rather closely 
punctured, densely covered with silvery depressed pubescence, 
without any erect black setae.

24. Paederus argentatus, n. sp. 
Head and elytra cyaneous, thorax and first four visible segments 
of the abdomen, red, the last two black. Anterior coxae internally, 
tibiae and base of the femora, obscure brownish testaceous, the rest 
black. Antennae black, scarcely lighter at the base. Distinctly 
pubescent. Length 7 mm. 
In build, size and coloration of the body very similar to P. amoenus, 
Er. ; distinct by the colour of the anterior coxae, less closely punc- 
tured elytra and especially by the very distinct silvery pubescence 
particularly of the abdomen. From the preceding species it is 
distinguished by its smaller and narrower build, narrower and much 
more thickly punctured head, and narrower and more distinctly 
punctured thorax. 
Head suborbicular, broader than the thorax, distinctly punctured 
at the sides in front, pubescence distinct, silvery. Mandibles black. 
Thorax long, oviform, distinctly but not closely punctured, the sides 
not bordered. Llytra half as long again as the thorax, parallel, 
more finely and less closely punctured than in P. amoenus, Er., and 
with distinct silvery pubescence. Abdomen finely but not very 
closely punctured, clothed with long silvery pubescence, not inter- 
spersed with any black setae.

25. Astenus H-signatus, n. sp. 
Black, elytra reddish testaceous, with the sides (except the 
postero-external angles) broadly, and a narrow median transverse 
band, black, forming a distinct black H-pattern. Antennae, palpi 
and legs testaceous. Length 5 mm. 
Head subquadrate, broader than the thorax, sides behind the eyes 
slightly convergent to the rounded posterior angles, sculpture close, 
umbilicate. Antennae moderate, all the joints longer than broad,
