. Bulletin of entomological research. Entomology. OBSERVATIONS ON SCALE-INSECTS (COCCIDAE)—IV. 19 rose-thorn. This applies, in a general way, to Bodkin's specimens ; but the apical extension of the test in angulata is fluted, whereas in bodkini it is perfectly smooth. The structural characters of the two species are, however, quite distinct. I have pleasure in dedicating this species to its discoverer. Pulvinaria aristolochiae, sp. nov. Female, adult. More or less cordate in outline and rather flattened; dorsum almost completely covered with a well-defined layer of flake-like wax which varies in colour from dirty grey to greyish brown. Antennae (fig. 12, a) of eight segments ; 3rd, 4th and 5th unusually long, the two first-named markedly swollen distally; 3rd about twice the length of the 4th; three long hairs on 2nd, one of which lies (in three examples) close up to the succeeding segment; there is also a long distal hair on the 3rd ; two on the 5th ; a single slender spine on the 6th, 7th and 8th, the last-named also with a few very short hairs. Legs (fig. 12, b) stout, long; tarsus relatively very short, less than one-third the length of the tibia ; lower digitules long. Fig. 12. Pulvinaria aristolochiae, Newst., sp. n., $ ; a, antenna ; b, leg ; c, marginal spines ; d, submarginal tubercle ; e, anal lobes. and very broadly spathuliform. Marginal spines (fig. 12, c) stout, pointed and placed rather closely together; stigmatic spines broken away in all the specimens, their points of attachment being continuous with the marginal series. Submarginal pores (fig. 12, d) very large, continuous, but rather widely separated. Anal lobes (fig. 12, e) with four stout spines near the apex, on the inner edge. Anal cleft short, usually a little less than one-sixth the entire length of the body. Anal ring with eight hairs. No derm cells present; but there are numerous circular spinnerets (? ventral), each having an inner concentric ring. Length, 5'7-7 "6 mm. Ovisac pure
