During June and July of 1926 while doing marine investigation at Tofino, Clayoquot Sound, on the west coast of Vancouver Island, I had the opportunity of examining certain birds for external parasites. The results from some hosts were so far removed from the normal Mallophagan population of most birds that it seemed worth while recording them at the time.

This species was described by Garrett (1925) from a single female taken at Cranbrook, B. C. The description of the male was added by Johannsen (1926) from specimens (1 ♂, 2 ♀ ) collected in Yellowstone Park. The life-cycle is now completed from material taken in S. E. Alaska in 1926.

Some interesting developments recently have taken place with reference to the systematic status and distribution of the mint flea beetle, as we know it in America, which tend to clear up the origin of the pest in this country.

Judging by five specimens before me the early spring generation (April-May) from southern British Columbia shows several points of distinction from the second generation, appearing in the latter half of June. The size is notably smaller, (♂ 36-40 mm.; ♀ 40-42 mm.; as compared with 45-50 mm.), the discal spot of primaries, especially in the ♂, is much narrower, and more as in the European chloridice, and the green of the underside is brighter and even along the veins shows only faint yellow sprinkling.

Length, 11 to 12 mm. Male. Front pale cinereous pollinose the parafrontal hair black; third antennal joint narrowly reddish below; basal aristal joint slightly longer than broad, the second elongate. Pleura yellow pilose. Three posterior acrosticals. Abdomen shining black, the sides usually very broadly castaneous, the apical segment pale brassy yellowish pruinose; rather broad apex of first and base of second segments cinereous pollinose. Second abdominal seqment with strong marginals. Fifth sternite simple, with moderately strong apical bristles. Ridges of posterior forceps moderately high, flattened, hairy on inner and outer surfaces, the apex as in figure 28; the outer forceps are as in A. plangens n. sp. (see figure 27).
