one shallow, the slight median line short but 
distinct, running between them, sometimes also 
visible in front, basal foveae very shallow, with 
a suggestion only of puncturation, surface other- 
wise uneven, shiny. //ytra rather flat, elongate- 
oval, nearly a half wider than prothorax, four 
fifths longer than wide, shoulders narrow but 
evident, no sinuation behind; striae with only 
traces of crenulation, extremely fine and hardly 
impressed, scarcely visible behind shoulders, a 
scutellary striole just traceable between I and 2, 
intervals flat, equal, 3 with a single pore behind 
middle, surface smooth and a little dull. The 
microsculpture of the elytra is formed by meshes 
which on average are much longer than wide 
and a little oblique; on the head and prothorax Fig. 1. Zvachysarus sericeus 
meshes are just visible near the margins. Under- a en 
side impunctate, tarsal joint 5 glabrous beneath. 
A little larger and flatter than 7. pa/lipes Germain, head with flatter 
eyes, practically as large as prothorax, which is wider in front, the sides less 
sinuate behind, the front transverse impression much deeper, elytra much more 
finely striate, sericeous, the meshes of the microsculpture oblique-elongate, 
instead of transverse.

Trachysarus punctiger sp. n. — Fig. 2. 
Length: 6 mm. Width: 2 mm. 
Piceous black, elytra faintly aenous, shiny; palpi, joints 1 and 2 of antennae, 
apex of elytra, and legs more or less ferruginous. 
Head convex, smooth, the deep oblique 
frontal foveae running on each side from the end 
of the clypeal suture to the margin of eye, a 
slight pore on vertex, eyes flat, antennae dilated 
towards apex, extending well beyond base of 
prothorax. Prothorax moderately convex, nearly 
a third wider than head, a sixth wider than 
long, widest just before middle, base and apex 
about equally wide, sides very narrowly bordered, 
gently rounded in front, straight behind, the pore 
and seta well before middle, hind angles obtuse 
and rounded; median line fine, transverse im- 
pressions distant from margins, the front one 
wide and deep, basal foveae small, but moderate- 
ly deep, rather finely punctate, the punctures 
extending, though less closely placed, both to
