their sacs, and if placed upon their backs they readily right themselves 

 by bringing their extremities together. The long white sacs are con- 

 structed in from 12 to 16 days ; the cephalic portion of their bodies 

 remains uncovered throughout the process. 



The males were obtained, after many failures, by rearing them on 

 the living plants of the Luzula. In their early stages they are very 

 like the females, but the subdorsal lines are wanting. When about to 

 pupate they generally leave the upper-sides of the leaves and seek 

 shelter beneath them, where they construct their glassy scales, and 

 escape in the perfect form in a few days ; this takes place from the 

 beginning of July. 



The male is now described for the first time, and the species is an 

 addition to our fauna. Abundant on a moist railway embankment 

 on the " Field wood-rush " {Luzula campestris) at Ince, Cheshire, 

 1890-91.

? immediately prior to fecundation. Ovate, narrowed behind, dusky yellow 

 or greenish-yellow, covered with a white mealy powder ; margins all round with 

 white waxy projections, two at the anal extremity longest ; eyes considerably behind 

 the antennae, shining black. Antennae of seven joints, of which the 7th is the 

 longest, then the 2nd, the others shorter and in length equal ; all with fine short 

 hairs, except the 7th, which has three or four long stiff ones. Legs short, tliinly 

 set with short hairs ; tarsi a little sliorter than the tibiae. 



Long, 1-50—2 mm. ; wide, 1 — 1*25 mm. 



? adult. Colour and shape as above. Antennae (fig. 5) of nine joints, of which 

 the 2nd and 3rd are the longest ; 1st, 4th, 5th, 6th, 7th and 8th in length nearly 

 equal, the 9th slightly longer than and these, together with the 8th, is wider than 

 the rest, all with fine hairs. Legs (fig. ha) long and slender, especially the posterior 

 pair, with fine hairs, tibiae as long again as the tarsi ; coxa with one long one ; claws 

 (fig. 56) with a strong tooth and a bulbous base ; digitules to claw only ; rostrum 

 iialf as long again as the antennae. 



I cannot give the exact measurements, as my specimens became twisted in the 

 preparation, but they are not less than 3 mm. long. Ovisac is composed of a thin 

 and extremely brittle material, so much so, that I have been unable to obtain a 

 single perfect example. 



J . Pale brown, mealy ; head rounded in front ; eyes and ocelli shining red- 

 brown. Antennae (fig. 5c) reproduced, of ten joints. Legs thinly set with short 

 hairs ; tarsi a little mo. e than one-third the length of the tibiae ; wings white, 

 reaching beyond abdomen ; last abdominal segment with two long and two short 

 white filaments, the latter not reaching beyond the closed wings. Long, 1"25 mm. 



Sac of the S long-oval, convex, composed of a thick, white, cottony substance.
