toriae rubianus Rothschild were seen. On A. tagala plants growing abundantly along the sandy eastern shore, where at the time the early instars of O. urvilleanus were numerous, no specimens of O. victoriae were found.
Predators.—It was noticed that on those islands where early instars of O. victoriae were found together with those of O. urvilleanus on A. tagala, the number of predators appeared to be higher than was the case in areas where O. victoriae is associated with the hostplant having, corky stems, generally growing in a more open and drier environment. Parasites have not been observed to attack this species.

OCCURRENCE OF THYMELICUS LINEOLA (HESPERIIDAE)
IN VIRGINIA
In recent years there has been a great amount of attention drawn to the rather rapid expansion of the range of the European skipper, Thymelicus lineola (Ochsenheimer) in the United States and Canada.
On June 21, 1968 I collected two fresh males of this skipper in Giles County, in the mountains of southwestern Virginia. They were taken in an open grassy meadow just north of Buckeye Mountain, about three miles west of the small town of Eggleston, Virginia. It was about 6:00 P.M. when they were first seen flying slowly near the ground among the tall grass. They were easily caught as they rested on the grass. No more were seen that day or the following day. A rainy period for the remainder of the time that I was in the area, hindered further collecting.
The foodplant, Phleum pratense L. was very common in the meadow and surrounding areas.—Gerald B. Straley, Eggleston, Virginia.
