5. PSYCHODA EEMINEA, Eto. 



FsycJioda erminea, Etn., ante, 2nd ser., vol. iv, 130, step 4a (1893), and vol. v, 

 pi. iv, Ps. 5 (detail), also p. 261 (1894). 



Wings very light brownish-grey, approaching whitey-brown or light drab, with 

 a satiny gloss and fringes to match (these shifting with changes of posture to whitish 

 and to blackish-grey), and marked in the disc with ten or twelve small dark hair- 

 spots, viz., six tufts, each marking the end of a row of the bristling hair ; one on 

 the mediastinal confluent with some dark hair at the base of the costa, and extending 

 into the costal fringe ; another immediately beyond the basal cells, on the bases of 

 the longitudinal nervures thereabouts ; and another larger spot at the base of the 

 axillar nervure and the adjacent portion of the wing-margin. The remaining 

 tufts intervene between the first six and these three, and comprise a spot by the 

 pobrachial fork on the anterior pobrachial, and another spot on the subcosta and 

 radial stem (praefurca) in an oblique straight line with the one just mentioned and 

 the tuft marking the end of the bristling hair on the axillar nervure. In addition, 

 a very small, obsolescent, 12th dark tuft is distinguishable on the cubitus, a little 

 before the middle of the wing. The outermost tufts on the subcosta, anterior radius 

 and cubitus, occupy three angles of an oblong, quadrilateral, faintly greyish cloud ; 

 and beyond the bristling hair, a narrow transverse fascia of the same tint, interrupted 

 at the prsebrachial nervure, extends from the end of the posterior radius to the end 

 of the posterior pobrachial, matching the hair towards the end of the prsebrachial. 

 AntennEe in $ 14 — IS-jointed, reaching to about the middle of the wing ; hair of 

 the flagellum arranged in a moniliform series of smooth oval verticils, nearly as in 

 Fs. humeralis (6), pearl-grey or greyish-white. Hair of head and thorax greyish- 

 white ; that of the abdomen very light brownish-grey. Indumentum of the legs 

 grey, with a satiny gloss. Basal joint in the superior J appendages short, slightly 

 dilated below ; apical joint very little longer than the other, narrowly falcate, with 

 a slight dilatation near the base in the dried insect ; figured from a specimen freshly 

 killed. Inferior (? appendages slender, rather similar to those of Ps. sexpunctata, 

 and more acute than acuminate. Length of wing, 1"6 to 2'25 mm.
