. Diptera Danica: genera and species of flies hitherto found in Denmark. Diptera. 70 Orthorrhapha brachycera. XXXIII. 243) describes the larva of the somewhat nearly related Chorisops tibialis Meig. This larva resembles a Sargus larva what may probably also be the case with the Beris larva. The Chorisops larva was found in earth with much decaying vegetable matter. The species of Beris are not very lively, they are especially found in low herbage and in bushes often near water. The genus comprises 5 palaearctic species of which 4 have hitherto been found in Denmark. Table of Species. 1. Abdome
