NOTES ON SIPROET A AND MET AMORPHA WITH FIGURES

OF SIPROETA EPAPHUS GADOUI MASTERS (NYMPHALIDAE)

Siproeta epaphus gadoui Masters (1967) was described from a series of specimens collected by Albert and Mary Lou Gadou at El Pao, Bolivar, Venezuela. The subspecies is of particular interest because it is inter­mediate in many respects between S. epaphus (Latreille) and S. trayja Hubner, which have been considered to be distinct species in the past. S. gadoui appears to be derived from trayja stock rather than from the geographically adjacent epaphus, although the entire Amazon Valley now separates trayja and gadoui. The description of gadoui was hurried in order to make the name available for a genus revision by Richard M. Fox and Alden C. Forbes and the new subspecies was not figured. The original description did promise figures in the coming revision of Fox & Forbes. The senior author of this revision, R. M. Fox, died on 25 April 1968 with the manuscript partially completed. F. Martin Brown com­pleted the manuscript which was finally published on 24 December 1971, albeit without figuring gadoui. I feel that it is important to figure this interesting butterfly and figures are hereby presented (Fig. 1).

The Fox & Forbes revision (1971) may not be readily available to all lepidopterists and a summary may be useful. The genus Metamorpha was divided into two genera: Metamorpha Hubner (type species elissa Hubner), and Siproeta Hubner (type species trayja Hubner). Differences were cited in venation (in M etamorpha a vestige of the posterior tip of the third disco cell ular is present on the forewing), male forelegs (in Siproeta the tarsus is little more than half the length of the tibia, in Metamorpha

it is one-fourth the length), and male genitalia (in Siproeta thc tcgumen and uncas are still separated by a suture, but in Metamorpha the suture has been lost and they are fused). A checklist of species and subspecies follows:

The only effect upon the Nearctic fauna is that Metamorpha stelenes, species number 524 in the Dos Passos (1964) checklist, should be placed in the genus Siproeta.

NEW FOODPLANT RECORDS FOR PAPILIO POLYXENES F. (PAPILIONIDAE)

That the larvae of Papilio polyxenes F., the eastern black swallowtail butterfly, feed solely on plants of the carrot family, the Umbelliferae, is well documented (e.g., Scudder 1889, The Butterflies of the Eastern United States and Canada II; Holland 1931, The Butterfly Book; Dethier 1941, Amer. Nat. 75: 61-73; Forbes 1960, Lepidoptera of New York and Neighboring States IV). The following three umbelli­fers have not previously been reported as larval food plants for this species.

On 1 June 1970, at the summit of Shaw's Ridge, Highland County, Virginia, I found two P. polyxenes larvae feeding on a meadow parsnip, Thaspium barbinode (Michx.) Nutt., which was growing in company with golden alexanders, Zizia aptera ( Gray) Fern., on a dry roadside bank along Route 250. I reared the larvae to
