In the course of the investigation on fungivorous insects, I have collected twelve species of larvae of Erotylid-beetles from Japan. The present paper deals with the key to genera, the taxonomic study on the general character of the larvae and three species of genera Aulacochilus and Neotriplax, together with some ecological notes. The key to genera by known Erotylid-larvae 1 Upper surface with distinct setigerous processes on lateral and dorsal side……2 Upper surface without setigerous processes……3 2 Body larger (than 12 mm), maxillary mala with many minute projections at inner side near by apex, urogomphi antlered…Episcapha Lacordaire Body smaller (6 mm in Dacne picta Crotch), maxillary mala smooth at inner side near by apex, urogomphi not furcated……Dacne Latreille 3 Urogomphi paired on dorsal side or single at middle, in the latter case bifurcated at middle……4 Urogomphus single and simple, not furcated……Microsternus Lewis 4 Urogomphus single and bifurcated, maxillary mala with larger hook-like projections……Aulacochilus Lacordaire Urogomphi paired, not furcated, maxillary mala with smaller hook-like or straight projections……5 5 Antennae longer than diameter of antennaria……Tritoma Fabricius Antennae conspicously shorter than diameter of antennaria……Neotriplax Lewis The key to Aulacochilus larvae Lateral and posterior setigerous processes of urogomphi distinct, 3rd antennal segment shorter than a longest conical projection of 2nd antennal segment……Aulacochilus japonicus Crotch Setigerous processes of urogomphi indistinct, 3rd antennal segment longer than conical projections of 2nd antennal segment……Aulacochilus bedeli Harold
