Abstract. — The genus Pseudobryomima includes three species, but these are probably congeners with the ten described species of Properigea. Pseudobryomima fallax (Hamp-son) was reared ex ovo on a fern, Pellaea andromedifolia (Kaulf.) Fee (Pteridaceae), and P. muscosa (Hampson) was reared on Polypodium californicum Kaulf. (Polypodiaceae) from field collected early instar larvae. Larvae began as blotch miners, but later instar larvae made shelters. The larva of P. fallax is described and illustrated. Key Words: Lepidoptera, Noctuidae, Quail Ridge, California, cliff brake fern, Polypo-diaceae, Pteridaceae, leaf miner The three known species of Pseudo-bryomima Barnes and Benjamin are closely related to the ten described species of Pro-perigea Barnes and Benjamin and may ul-timately prove to be congeneric; all are ex-clusively Nearctic. None of the Properigea or Pseudobryomima has had their biology previously reported. We collected a female of Pseudobryomima fallax (Hampson) on the Quail Ridge Ecological Reserve, Vaca Mountains, Napa County, California, 38°29'20"N latitude and 122°08'14"W lon-gitude, at an elevation of 440 meters. The species is illustrated by Hampson (1906: plate 105, fig. 8). The moth was retained for eggs. On October 23, 1994, when the parental female moth was collected, we had dry fall conditions with relatively few plants that were still green. Under wet spring condi-tions the Quail Ridge site would have host-ed several hundred available food plant candidates (anonymous 1993). The dry conditions led to the discovery of a food plant. Biology Upon eclosure, the first-instar larvae of Pseudobryomima fallax were offered a leaf from all the plants we could find in nearby Cold Canyon that were still green in No-vember. The flora has been well document-ed for this region (Weathers et al. 1985, Hickman 1993). The first-instar larvae failed to feed on the following: Achillea millefolium L., Aristolochia californica Tor-rey, Brickellia californica (ToiTey & Gray) A. Gray, Ceanothus cmieatus (Hook) Nutt., Cercis occidentcdis Torrey, Dryopteris ar-guta (Kaulf.) Maxon, Eriodictyon califor-nicum (Hook. & Arn.) Torrey, Heteromeles arbutifolia (Lindley) Roemer, Lactuca sp., Lupinus albifrons Benth., Arctostaphylos manzanita C. Parry, Mimulus aurantiacus Curtis, Oxalis sp., Pinus sabiniana Doug-las, Quercus douglasii Hook. & Arn., Ru-bus ursinus Cham. & Schldl., Salix sp., Sambucus mexicana C. Pressl, and Vitis californica Benth. Fungi, lichens, and dead wood also were rejected. They fed only
