Pseudhypoptus eurylobus Champion 1911

Oblong-ovate, rather convex, black; very sparsely clothed with small cinereous scales, the elytra with some denser patches or streaks of white scales along the flanks and towards the apex, the surface also set with short, decumbent, scattered setæ. Head and rostrum densely, confluently punctate, the rostrum shorter than the prothorax and finely carinate along the sides. Prothorax transverse, narrowed and feebly constricted in front, the sides parallel at the base in ♂, the hind angles acute and extending outwards; the surface densely, uniformly impressed with small rounded punctures. Scutellum transverse. Elytra convex, a little wider than the prothorax in ♂, broader in ♀, acuminate at the apex, the humeri not prominent; coarsely punctate-striate, the striæ becoming deeper at the apex, the interstices feebly convex and rugulosely punctate. Beneath finely punctate; ocular lobes of the prothorax continued round to the anterior coxæ, and sharply separated from the prosternum; first ventral segment deeply excavate down the middle behind in ♂. Tibiæ sharply unguiculate in ♂, unarmed in ♀, the anterior and intermediate pairs obsoletely denticulate.
 
Length 10 1/3—11½, breadth 3 7/8—4½ millim. (♂ ♀.)

Hab.MEXICO (ex coll. Solari: ♂), Huetamo in Michoacan (Höge: ♀).

One male and two females. Separable from P. parcus by the still more extended inferior portion of the ocular lobes, the less rugose rostrum, the acute hind angles of the prothorax, and the less distinctly margined base of the prothorax and elytra, the elytra a little wider than the prothorax in the male. The posterior tibiæ are without definite teeth.
