identical with those of Chlenius reichei, Chd., with which 
it also assimilates in the characteristics of the palpi in both 
SEXeS. 
It has little in common with Chlenius bohemani, Chd., 
with which species Dr. Péringuey inexplicably confused it, 
when I submitted it to him for determination.

Chlenius (Vertagus) marleyi, sp. n. 
Length 1] mm. (¢)-124 mm. (¢); width 4-5 mm. 
Head and prothorax metallic blue, pubescent, the latter in 
one example with some lighter green reflections within the 
grooves of the lateral margins ; palpi and mouth-parts 
piceous, a little reddish at apices; first joint of antennez 
reddish flavescent, the rest black. LElytra subopaque, deep 
purplish blue with on either side a supra-apical orange spot, 
occupying the intervals between striz 3 to 8. Underside 
shiny jet-black ; legs reddish flavescent with knees, tibia, 
and tarsi black. 
Head elongate, plane, finely and closely punctured except 
on vertex, where the puncturation becomes faint and irre- 
gularly spaced. Eyes very prominent ; labial palpi securi- 
form in both sexes, maxillaries securiform in males and 
truncately clavate in females ; antennze elongate, the middle 
joints a little widened and compressed. 
Prothorax explanate from the anterior angle to about 
middle, where it is slightly angled, thence roundly con- 
tracted to posterior angle, lateral margins sharply reflexed, 
forming a deep fold which widens posteriorly, apex straight, 
a little narrower than the base, which is slightly emarginate, 
disc very little convex, coarsely sub-confluentiy punctate, 
median line distinct, not quite reaching base and with deep 
basal fovez on either side. 
Elytra about one-third wider than prothorax, shoulders 
broadly rounded, sides in the male nearly straight, in the 
female a little ampliated to beyond middle, striz deep, not 
perceptibly punctate, intervals a little raised, densely 
shagreen-punctate, and briefly pubescent. 
Nearly allied to C. fenestratus, Chd., in which the palpi 
and antenne are similarly constructed. Judging by the 
description—for I have not seen the insect,—C. effugiens, 
Pér., must be very nearly related to C. marleyi, but differs 
from it in having unicolorous flavescent legs. It is also 
doubtful whether the very slight angulation of the sides of
