1905.] OF PHYTOPHAGOUS COLEOPTBKA. 421 



OeDIOIS^YCHIS MILLEPORA, Sp. 11. 



Under side and legs dark brown ; the head black at the vertex, 

 testaceous loAver down ; antennae (the basal joints excepted) black ; 

 thorax testaceous, impunctate ; scutelluni black ; elytra testaceous, 

 closely and finely punctured. 



Length 4-4| millini. 



Head rather strongly punctui'ed at the sides of the vei-tex, the 

 latter bluish-black ; clypeus testaceous, strongly carinate at the 

 middle, the anterior portion forming a transverse ridge ; antennae 

 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 

 . 0. ohscuripennis 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. ohscuripennis ; pro- 

 sternum very narrow and elongate, also carinate, fulvous ; under 

 side and legs piceous. 



Hah. Colombia ; also Mexico. 



The testaceous colour of the anterior portion of the head, the 

 distinctly punctured vertex, and the colour of the antennee and 

 under side separate this species from the preceding one, and the 

 partly testaceous head from 0. obscurij^nnis. 



Oedionychis distixcta, sp. n. 



Convex, widened posteriorly, testaceous ; terminal joints of 

 antennge black ; thorax with strongly rounded and deeply sulcate 

 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 sulcate between the eyes, the latter widely separated, 

 frontal tubercles rather obsolete ; carina broad anteriorly ; clypeus 

 pei-pendicularly deflexed, bounded by an acute ridge above ; 

 antennae robust, black, the lower four joints testaceous, third 

 joint shorter than the fourth, the following joints also less 

 elongate than the fourth one ; thorax not more than twice as 

 V>road 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 impunctate ; elytra strongly widened at the 

 middle and convex, the reflexed margins not very broad, the 

 surface deeply and closely punctured anteriorly, intermixed with 

 some smaller punctures, the posterior poi'tion extremely closely 

 and more finely punctured ; metatarsus of hind legs very short ; 

 claw -joint very strongly inflated. 



Hab. Colombia. 



More strongly punctu.red and convex than most of the allied 

 species, the thorax of characteristic shape, and the antennae with 

 pale basal joints.
