Adelium marginatum, n. sp. 
^?. — Elongate-oval, depressed, bronzed brown, with a 
patch at each side the disk of prothorax, and the elytra at 
base and down by each side near the margin, darker, shin-

head and prothorax somewhat strongly and closely rugose- 
punctate ; the latter irregularly depressed down the median 
line, a well-marked impression at each side the middle at 
the base, apex slightly sinuously emarginate, sides finely 
margined, moderately rounded to behind the middle, thence 
somewhat sinuously narrowed to the hind angles, which 
are obtuse ; base closely applied to the base of the elytra,
