Prothorax with the side pieces not separate; prDsteriiiim separating the coxic, usually prolonged behind; cuxal cavi- ties open behind. MesoHternum articulating with the prosternum, frequently emarginate in front; side pieces not attaining the cox;e, Metasternum large, side pieces narrow. Elytra rounded behind, entirely covering the abdomen. Abilomen with five free ventral segments, the lirst some- what longer than the others. Coxtc, anterior oval or rounded; middle ones rounded; posterior ones transverse; all of them separated by the re- spective sterna. Legs short; tibiae nearly linear, with small terminal spurs; tarsi sometimes 5-jointed, with the fourth joint sniallor; the hind ones are only 4-jointed in the males of several genera; the joints are clothed beneath with long hair, and the first three of the anterior pair are frequently dilated in the male. Insects of small size and of variable form, but never very de- pressed, and with the thorax nearly or quite us wide as the elytra. They live on fungi aud other decomposing vegetable matters. Some arc found flying in the evening twilight, and upon board- piles. I have limited this family in the same manner as Lacordairc, and cannot adopt the views of Duval, who has joined with it Syl- vanus, and excluded Telmatophilus. I do not find the anterior coxa) globose, as described by Erichson, Lacordairc, and Duval, except in Atomaria and the allied genus Epistemus. The characters of the family are nearly tliose of Ciicujida-, but the greater lengtli of the first ventral segment, and
