a virgin female to a male. After mating for 1 h 39 min a crab spider (Thomisidae) attacked and grabbed the female. After 4 h 51 min I left them while they were still in copula but put a cage over them. When I returned half an hour later the copulation was over; the male was flying in the cage while the female was still held by the spider among the vegetation.
The other observation concerns a pair of Pararge aegeria (Satyridae) kept in a cage in the laboratory, where the male for unknown reasons died during copulation. They were found in copula on 5 February 1985 at 1100 h. It was still dark in the cage, and the pair must have been mating since 1840 h the day before when the light was switched off automatically. At 1340 h the light was turned on. At 1700 h the female was found flying in the cage with the male hanging from the tip of her abdomen. Upon inspection he was found to be dead. On 8 February the female was still alive and attached to the dead male. On 15 February the female was found dead, still in copula with the male.
Although not proven, it seems plausible that the copulation is ultimately terminated by the male. Further observations and experiments would be interesting.

SATYRIUM AURETORUM AURETORUM (BOISDUVAL): A NEW SPECIES FOR OREGON (LYCAENIDAE)
The senior author received a number of butterflies from the junior author among which were three female Satyrium auretorum auretorum (Boisduval) with the following data: OREGON: Lake Co.; 2 miles south of Lakeview, 1 June 1981, leg. Ray Albright. Dornfeld (1980, The butterflies of Oregon, Timber Press, Forest Grove, OR) does not report the species for the state. The species has been expected there; it was taken towards the border in Siskiyou Co., California (Klamath River, near 1-5, fide S. O. Mattoon). This new location also brings the species to within 20 miles of the Nevada border, another state where it is unrecorded.
We thank S. O. Mattoon for providing the northern California record.
