380 COLEOPTERA. 
equal length and breadth, curvedly narrowed towards and of the same 
width as thorax at the base; with fine sutural striae and a short basal 
impression alongside each. Hind-body as broad as elytra, basal segment 
almost as long as they are, broadly margined, horizontal, and bearing a 
very short band of sponge- -like greyish clothing at its base, the other seg- 
ments deflexed. 
Legs elongate and slender, femora medially subclavate ; posterior tibiae 
straight and very slender above but with a third of their apical portion 
slightly expanded externally. 
Antennae rather slender and elongate, finely pubescent; basal joint 
cylindric, stout, nearly twice the length of the next, joints 3-8 almost 
equally elongate, 9th and 10th thicker and shghtly longer; the terminal 
larger, straight at one side, the other widest behind the ndle and gradu- 
ally attenuate towards the extremity. 
Maxillary palpi slender, shorter than the antennae, 2nd joint curved, 
more gradually incrassate near the extremity than at the base, 3rd thick 
and very short, 4th half of their whole length, thicker near the base than 
at the middle, its clavate apical portion a third of its whole length. 
Male Mesosternum pubescent, grooved along the middle, with carinate 
edges there. Metasternum strongly convex along the middle. Basal seg- 
ment short, with yellowish sponge-like vestiture ; 2nd very large, not very 
broadly depressed medially, the sides of the depression strongly elevated 
and forming laterally compressed tubercles near the apex; 3rd and 4th 
short and widely emarginate; 5th semicircularly, hardly visible in the 
middle; 6th as long as the preceding 3 combined, apparently punctate, 
and bounded behind by the last dorsal segment. Trochanters very elon- 
gate, extending beyond the sides of the body and quite visible from above. 
InP; ventralis (2742) the mesosternum has a simple mesial carina. The 
metasternum is a good deal shorter, and the 2nd ventral segment is 
concave for half of its width but is not tuberculate behind.

Oakden, near Mount Algidus. imecorerea by Mr. Roderick Urquhart, 
along with some other Coleoptera, on the 25th September, 1913, and named 
in his honour. 
3832. Pselaphus oviceps sp. nov. 
Nitid, fusco-rufous, palpi and tarsi testaceous ; sparingly covered with 
subdepressed, slender, brassy setae. 
Head ovate, widest in line with the shghtly convex eyes, almost as broad 
as the middle of thorax there; median channel deep, extending as far as 
the back part of the eyes, somewhat expanded between these : occiput 
convex, antennal tubercles horizontal. Thorax, excluding the broad neck, 
rather longer than broad, widest near the middle ; with a small punctiform 
fovea at the middle of the base, the larger lateral ones shallow. Elytra of 
the same width as thorax at the base, gradually expanded behind, slightly 
broader than long; with fine sutural striae, alongside each of these there 
is a deep, short, basal depression with subearinate outer edges. Basal 
segment of hind-body nearly as long as the elytra, rather broader near 
its extremity. 
Antennae finely pubescent, their 2nd joint quite half the length of 
the basal, joints 5-8 rather longer than 3rd or 4th, 10th slightly shorter 
than 9th.
