Macy: Adelpha bredowii
Vol.12: nos.5-6
butterfly, the Purple Hairstreak, A tildes halesus, is sometimes found here, even in northern Oregon, and was first reported for the state by the writer {Can Ent. 64: 144; 1932).
The specimen of A. bredowii caught in Lincoln County was in the Canadian Life Zone a narrow strip of which extends along the ocean often reaching inland no more than several hundred yards, but it probably was a migrant. The southern Oregon coast locality is mountainous with forest of Douglas Fir, other conifers, and some deciduous trees.
Although this butterfly has not been reported in the most recent check lists for Washington and British Columbia (Leighton, Butt. Wash., Seattle, 1946; Jones, Annot. Checklist Macrolepid. B. C, Ent. Soc. B. C, 1951), it is clear that it occurs regularly in Oregon, even in the northern portion. Although it probably breeds in the state, it is possible that the population is reinforced by migrants.

FINDING MEGALURA PETREUS IN COLORADO
1 had never seen a live "Dagger-wing" before and had certainly not expected to see one of these tropical butterflies in Colorado, but it happened that way. 1 am teaching Biology and English at the Olney Springs High School here, and one afternoon two of my Biology students and myself went hunting for general insect specimens for class study. We walked into a blooming alfalfa field just north of the Methodist Church when one of my students evinced awe at the sight of an orange-colored butterfly visiting the alfalfa blossoms. It looked, at first glance, much like a male Dryas julia nudeola which I had caught in abundance on Key Largo, Florida, just two weeks previously. The student missed the butterfly twice and then I stalked it and netted it easily on one of the alfalfa blossoms. It turned out to be a very worn Megalura petreus Cramer, which had been flying in a due north - northeast direction. I had been in Colorado exactly a week when I found this butterfly, and not a single specimen did I find in southern Florida where they are supposed to occur! The butterfly was caught on August 31, 1958, just north of Olney Springs, Crowley County, Colorado.
