ail 905. ] OF PHYTOPHAGOUS COLEGPTERA. 421 
OEDIONYCHIS MILLEPORA, Sp. 0. 
Under side and legs dark brown ; the head black at the vertex, 
testaceous lower down ; antennze (the basal joints excepted) black ; 
thorax testaceous, impunctate ; scutellum black; elytra testaceous, 
closely and finely punctured. 
Length 4-43 millim. 
Head rather strongly punctured at the sides of the vertex, the 
latter bluish-black ; clypeus testaceous, strongly carinate at the 
middle, the anterior portion forming a transverse ridge; antennze 
black, the lower three joints more or less stained with flavous, 
third and fourth joints equal, terminal joints rather short and 
stout; thorax short and transverse, nearly similar to that of 
O. obscuripennis Jac., with a narrow transverse sulcus each side 
of the basal margin, the disc impunctate; scutellum black; elytra 
of the same shape and punctuation as in 0. obscuripennis : ; pro- 
sternum very narrow and elongate, also carinate, fulvous ; under 
side and legs piceous. 
Hab. Colombia ; also Mexico. 
The testaceous colour of the anterior portion of the head, the 
distinctly punctured vertex, and the colour of the antenne and 
under side separate this species from the preceding one, and the 
partly testaceous head from O. obscuripennis. 
OEDIONYCHIS DISTINCTA, Sp. n. 
Convex, widened posteriorly, testaceous; terminal joints of 
antenne black ; thorax with strongly rounded and deeply suleate 
sides, impunctate ; elytra deeply, closely and strongly punctured, 
more finely and closely so towards the apex. 
Length 8 millim. 
Head with a few deep punctures at the vertex, deeply and 
broadly suleate between the eyes, the latter widely separated, 
frontal tubercles rather obsolete ; carina broad anteriorly ; clypeus 
perpendicularly deflexed, bounded by an acute ridge above ; 
antenn robust, black, the lower four joints eS OEES, third 
joint shorter than the fourth, the following joints also less 
elongate than the fourth one; thorax not more than twice as 
broad as long, rather wider at the sides (longitudinally), the latter 
strongly rounded, with broadly flattened sulci, the anterior angles 
slightly mucronate, the anterior margin deeply concave at the 
middle, the disc impunetate ; 5 elytra. strongly widened at the 
middle and convex, the reflexed margins not very broad, the 
surface deeply and closely punctured aniesion ly, intermixed ‘with 
some smaller punctures, the posterior portion extremely closely 
and more finely punctured ; metatarsus of hind legs very short 
claw-joint very strongly inflated. 
Hab. Colombia. 
More strongly punctured and convex than most of the allied 
species, the thorax of characteristic shape, and the antenne with 
pale basal joints.
