A NEW FOODPLANT RECORD FOR ECPANTHERIA SCRIBONIA
(ARCTIIDAE)
During a collecting trip to Florida in 1968 I found a larva of Ecpantheria scribonia (Stoll) feeding on the underside of a fern, Polypodium aureum L., 2 miles southwest of Satsuma, Putnam County, Florida. This larva, when collected on 31 June 1968, was in the penultimate instar. It pupated on July 26th and emerged, as a female, on 14 August 1968. The host fern is epiphytic on trees, especially palmetto, and has a subtropical and tropical distribution. A search of the literature has proven this a new hostplant record, and apparently is also the first time any fern has been recorded as a foodplant for this moth. Sidney A. Hessel kindly assisted with the identification of the fern.
As a postscript, I would like to add that I was brought a last instar larva of -E. scribonia collected by Eugene S. Morton at Leete's Island, Guilford, New Haven County, Connecticut, on 29 October 1968. After some prolonged feeding on dandelion and plantain, it pupated; an adult female emerged on 13 December 1968. There seem to be no previous records of larvae in Connecticut. E. scribonia occurs further north, at least to Massachusetts and southern Ontario, but is rare in Connecticut.
Both specimens have been deposited in the Peabody Museum of Natural History, Yale University.

CRAMBIDIA PURA (ARCTIIDAE: LITHOSIINAE) NEW FOR CANADA
During the summer 1969 two lepidopterological teams were working at the Biological Station of Queen's University, Kingston, Ontario, in Chaffeys Locks, Leeds Co., Ontario. One team was from the Royal Ontario Museum, the other from the Dept. of Biology of Queen's University (Prof. R. Harmsen). Both teams worked together in identifying and coordinating the catches from six "Black Lights," of which five were located at the station and one at Glenburnie, Frontenac Co., Ontario. The lights at the station were in rich deciduous forest, the light in Glenburnie in normal farming country.
In past years the lights at the station had attracted a few rare Lithosiinae, like Cisthene unifascia Gr. & Rob. This year we took for the first time at the station Crambidia casta Packard which was known to occur in this part of the country.
In Glenburnie, however, numerous specimens of Crambidia pura Barnes & Mc-Dunnough, a species never before recorded from Canada were taken. It was described from North Carolina, and Forbes (1960, Lepidoptera of New York and neighboring states, pt. IV. Cornell Univ. Agr. Exp. Sta. Mem. 371) gave its range as Minetto, New York; Lakehurst, New Jersey, and North Carolina.
In Glenburnie Crambidia pura, the identity of which was ascertained by genitalic dissection, would seem to have two generations, one at the end of June, the other in the middle of August.
