NEW SKIPPER AND BUTTERFLY RECORDS FOR SOUTHWEST LOUISIANA
by Roy O. Kendall
Over the years lepidopterists have, for some unknown reason, failed to collect in Vernon, Beauregard and Calcasieu Parishes of southwest Louisiana. This paper will record for the first time, forty species which may be found in these or adjoining parishes. Two of these species: Pholisora catullus (Fabricius) and Erynnis zarucco (Lucas) were not included in the list for Louisiana by Lambremont (1954).
Collecting was accomplished on a sampling basis during the period 1955 through 1961. Intensive collecting in this area would disclose many more species than are here recorded. The specific area in which samplings were taken is bounded on the west by the Sabine River which divides Louisiana and Texas from a point near Logansport, De Soto Parish, south to the Gulf of Mexico. Contiguous hardwood forests characterize the west boundry of the collecting area. East of the Sabine River one finds a vast amount of piney woods cut by numerous creeks or small streams which drain into the Sabine River to the west or the Calcasieu River to the east, both terminating in the Guff of Mexico.
Arrangement of this paper follows the forthcoming Synonymic List of Nearctic Rhopalocera by Cyril F. dos Passos who kindly checked the manuscript and offered helpful suggestions. The nearest city to the locality in which each specimen was collected is recorded below. Most of the records are from DeQuincy and Lake Charles, in Calcasieu Parish, and Leesville, in Vernon Parish. By and large the specimens were found within the corporate limits of the various cities. In those instances where immature stages were reared, the larval foodplant is given.

A PRELIMINARY STUDY OF FOODPLANT PREFERENCES IN
THE LYCAENA HELLOIDES COMPLEX (LYCAENIDAE)
IN COLORADO
by Donald S. Chambers
I. Laboratory Studies of helloides — like Populations
The purplish Copper of the Rocky Mountains, described from Alberta as florus by Edwards, has recently been referred to the northeastern Lycaena dorcas Kirby because of their very similar appearance. The range of florus is, however, isolated from that of dorcas and lies in conjunction with the area occupied, at lower altitudes at least, by L. helloides Boisduval, and most writers have considered florus to be a race of helloides. Brown (1955) sees dorcas and helloides as a "well-defined cline", but Clench (1958) believes they are distinct species for the following reasons: first, they have different determined food-plants (dorcas feeds on Votentilla, helloides on "Polygonum and possibly others — but not Fotentilla"); second, the two are sympatric but easily separable throughout a broad zone in the Michigan to Manitoba area; third, "there is no 'perfect intergraduation' across the continent as the authors state, though if large series are not seen it might appear so"; fourth, dorcas is single-brooded while helloides is multi-brooded. The present study is an attempt to determine the food plant(s) of florus and thereby disclose its true affinities.
An oviposition choice situation was presented to three florus females (Group I) collected near Gothic, Gunnison County, Colorado (elevation: 10,000 ft.). Freshly cut, roughly equal-sized sprigs from five plants were placed in moist earth in a flower pot covered by a broad lamp chimney with marquisette netting over the top. The tops of the sprigs were leveled so that all were equally accessible to the females. About three inches of open space were left below the cloth. Throughout this and the following
