im.i 165 



tubular spinnerets (fig. 5b), and very small round discs surmounted by an extremely 

 email spine ; margins with numerous strong spines. Abdominal lobes large, each 

 with a single long hair and two or more short spines. Ano-genital ring large, with 

 eight long hairs. Antennae of seven (sometimes six) joints ; of which the 3rd, 4th 

 and 7th are the longest, Ist and 2nd stouter and shorter, 5th and 6th shortest ; 

 those with only six joints have the 3rd and 4th united, thus the 3rd becomes the 

 longest (fig. 5) ; terminal joint with several long hairs (6 ?), there are also long hairs 

 on the other joints, except the first, which is furnished with two short spines. Legs 

 (fig. 5a) strong ; tibiae and tarsi equal, the former having two stiff hairs or spines 

 placed together near the tibio-tarsal joint, one of them being longer and stouter than 

 the other. Claw long and slender; digitules simple. 



Length of restored specimens, 2 — 3 mm. ; width, 1 — 1^ mm. 



Sac felted, white or yellowish-white, elongate, oval, slightly flattened, posterior 

 half in some specimens distinctly segmented ; abdominal extremity open. 



Length, 31 — 5 mm. ; width, 1 — If mm. 



Contains an average of 170 pale yellow or straw coloured ova. 

 Mab. : on Agrostis vulgaris, Itumex, Pferis, and Ulex. Frequently 

 in company (on the same leaf) with Eriopeltis festucce, and more rarely 

 with Signoretia luzulce. At Ince, and Manley, Cheshire, August and 

 September, 1890. 



The seven-jointed antennae are abnormal ; in this respect it is 

 like U. Bnithhgi, Mask. (Trans. N. Z. Inst., 1889, p. 145), but it differs 

 from the latter in the form of the antennje, legs, and other important 

 characters. The large sac will at once distinguish it from any other 

 described species. 



Some of the specimens recorded by Mr. Douglas (Ent. Mo. Mag., 

 vol. xxiv, p. 160) from external characters only, under the assumed 

 name of Eriopeltis Lichtensfeinii, Sign, (previously Tl.festucod, Sign , nee 

 Fonsc), have been kindly forwarded to me for examination, and prove 

 to be identical with the above ; but the species is generically different 

 from that described by Signoret {cf. Ess. Cochen., p. 183, pi. viii, figs. 

 3, and 3«— /). 



Eriococcus fkaxini, n. sp. 



$ adult. Bright red, subglobose ; each segment above with a single row of 

 flanged tubular spiimerets (fig. 6b), transversely arranged, and short scattered hairs, 

 which are longer towards the abdominal extremity. Antennae (fig. 6) of six joints, 

 each successively shorter and narrower, except the 6th, which is about equal to the 

 2nd in length, and is furnished at the end with four or five slender hairs. Legs 

 (fig. 6a) very short ; femora with one very long hair ; tibiae and tarsi equal ; claws 

 rather long and slender. Digitules simple. Ano-genital ring very small, with six 

 extremely small hairs. Anal setiferous lobes nearly obsolete, wide apart, each with 

 a single medium-sized hair; near the lobes are several shorter hairs. Rostral fila- 

 ments very long.
