Description

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1906 edition. Excerpt: ... of the elongate second, and about five times as long as its own width near the apex of the joint, third joint rather more than twice as long as wide; club nearly equal in length to the two preceding joints together. Thorax microscopically longitudinally rugulose; the abdomen elongate, as long or longer than the head and thorax together. Male with the thorax wholly dark and metallic, the hind coxae conspicuously so, except at the apices, which are pallid. The abdomen is pale yellow or whitish basally, black or dark and metallic on the apical segments. The antennae have nine distinct joints, scape, pedicel, four funicle joints and a three jointed club, in addition to two or three ring joints. The scape is ovate and of enormous size, being greatly dilated, the first and second funicle joints are elongate, slender and subequal, the two following are more robust, especially the fourth. The marginal vein is normal, not noticeably thickened. I have examined one female and three males of this species. The latter are mostly more or less discolored. They appear to closely resemble the female in color, but the abdomen is perhaps more extensively pallid. Length.8--1.5 mm. Hab. Java, Pekalongan (Muir); from eggs of cane Delphacid. (5) Ootetrastichus homochromvs sp. nov. Like 0. basalts in appearance, the thorax and hind coxae dark and metallic, the base of the abdomen widely, and the legs, including the front and middle coxae, pallid. This species is easily distinguished from 0. basalts by the length of the first funicle joint of the antennae, which is distinctly but not greatly longer than the second, and is only about, twice as long as its greatest width, subequal to the pedicel or a trifle longer. Length 1.2 mm. The male is not known. JTab. Amboina...show more
