. Bulletin of entomological research. Entomology. * Fig. 3. Pseudococcus inquilinus, Newst., sp. n. $; a, dorsal and, b, ventral surface of anal lobes ; c, lateral abdominal cerarii; d, body setae; e, hair of anal ring. Pseudococcus perniciosus, Newst. & Willcocks, var. Ovisac of female. Arranged in a similar way to those of typical P. perniciosus* but the more or less globular masses are smaller. The examples are so badly weathered, however, that it is not possible to give details of the structure of the individual ovisacs. Female, adult. * Under pressure of the covering glass the form is narrowly ovate. Antennae of seven segments. One pair of cerarii present on the anal lobes (fig. 4, a), the spines sharp and somewhat slender, with a few obtusely triangular gland-pores scattered around them. No typical lateral abdominal cerarii present, but their position is indicated by a single, faintly lanceolate spine (fig. 4, c), with from 1 to 2 simple supplementary setae at some distance away from it: the spines are traceable in some individuals on the last 3-4 segments, in others on the penultimate segment only. Body spines (fig. 4, d) minute, faintly lanceolate, and very scanty indeed ; hairs small and also very scanty. Anal lobe setae (fig. 4, b) slightly longer than the anal ring setae (fig. 4, e). Integument very thickly set with gland-pores (fig. 4, c, c), more especially so along the margin ; these are of three kinds : multilocular, tubular and obtusely triangular ; the first-named are arranged in narrow transverse bands on the dorsal surface of some of the abdominal segments, elsewhere they are irregularly disposed on both surfaces. Length of 53 adult $$ varying between 2'1 and 2*7 mm. * Newstead & WiUcocks. Bull. Ent. lies., i, p. 138 (1910)..
