Hemilypus

Hab.GUATEMALA, Cerro Zunil 4000 feet (Champion).

Caput post oculos haud constrictum; rostrum breve, crassum. Antennæ graciles. Tarsi articulo basali sequente duplo longiore. Prosternum post coxas minus abbreviatum, epimerorum apicibus haud conjunctis. Abdomen sutura prima ventrali profunda.

This genus resembles the eastern Aderorhinus in appearance; the prosternum behind exhibits a triangular piece, the apex of which separates more or less widely the apices of the epimera. It differs from Eugnamptus by the head being elongate and less constricted; the prosternum longer behind the coxæ; the first ventral suture deep; the basal joint of the feet shorter; and the pygidium not so completely covered. It should be placed between Aderorhinus and Eugnamptus.

A species closely allied to H. obliteratus, but evidently distinct, is represented by a single example that is too immature for description.
