not close, coarser than those of the thorax. Legs robust; the 
tibiz with a minute terminal spur. 
Larger and broader than Z. priscus, with finer sculpture, and 
thicker, differently formed antenne. Differentiated from 
L. erassicornis by its less robust antenne and legs, straight-sided 
thorax, &c. ; and from Z. pubescens by the truncate apex of the 
thorax, &c.

1404. Adelium cheesemani, n.sp.—Convex, sub-oblong, not 
parallel, attenuated posteriorly ; glossy black, antennee and palpi 
dark red, legs piceous, tarsi fulvous. 
Head short, immersed up to the eyes, obliquely rounded to- 
wards the forehead, the latter nearly truncate, rather finely 
punctured, more closely and coarsely near the eyes; epistome

sides with distinct rims, rounded anteriorly, a little natrowed yet 
almost straight behind the middle; hind angles nearly rect- 
angular, not protruding, resting on the elytra, the anterior 
rounded, moderately convex ; distinctly but not coarsely, and 
irregularly punctured, the punctures sometimes confluent, with 
several larger punctures similar to those on the forehead, an 
elongate depression near each side before the middle, two others 
(longitudinal) near the base, and an obsolete transversal im- 
pression uniting these latter. Scwtellum broad, minutely and 
distantly punctured. lytra elongate, oviform. widest behind 
the middle, somewhat broader than thorax, a good deal narrowed 
behind, distinctly marginated ; distinctly punctate-striate, some
