. The fur seals and fur-seal islands of the North Pacific ocean. Sealing; Seals (Animals). INSECTS OP THE PEIBILOP ISLANDS. 553 IX. AOAKINA. Fio. 1. By Prof. Herbert Osborn. Haematopinus callorhini Hertert Osborn, new species. (Type, No. 3501, ) Head but slightly produced, less than a semicircle in front of the antennae, wider behind the antennae than in front; eyes inconspicuous or wanting; dorsal surface with a very strong basally swollen lateral bristle and a number of stiff shorter bristles or spines merging anteriorly into short blunt spines; posterior margin subangular and projected on to prothorax; beneath with long slender bristles posteriorly and short blunt spines anteriorly; antennae flvejointed, basal joint very large, succeeding joints gradu- ally diminishing in size but of nearly equal length. Thorax wider than long, concave in front and behind, lateral mar- gins rather evenly arcuate; prothorax produced posteriorly, nearly reaching abdomen; sutures of pro- meso- and meta- thorax converging near posterior margin, posterior margin of meso- thorax strongly c^itinous, surface bristly and spiny, meso- and meta- thorax each with larger bristles. No sternal plate, coxae wide apart, and surface of sternum scantily armed with short spines. Abdomen widest near the middle, tapering to apex; set with short stiff spines and bristly hairs; the spiracles opening in small prominent tubercles; beneath with short spiny hairs. Legs nearly uniform in size, middle and posterior ones slightly larger; middle and hind tarsal claws fitting into a semicircular cup on the spur of tibia. Genitalia of male located dorsally, most apparent from above, where the chitinous structure is conspicuous, especially the two bars converging forward so as to form a triangle, from base of which, at apex of abdomen, the protruding penis and hooks appear as a second triangle. Length, 2 mm. This species falls in Haematopinus^ on account of the flvejointed antennae and structure of sternum
