first-mentioned, which is conterminous therewith. The bristUng hair interior to 

 this line of spots is longer than elsewhere, and by change of posture and illumina- 

 tion becomes whitish, or hoary, or flaxen-brown, while the shorter hairs either match 

 with the remaining smoother brownish hair of the disc and fringes, or appear 

 blackish ; or, when the wing points away from the light over a dark background, 

 the hair throughout becomes dull or glossy bronze-brown, except the further part of 

 the costal fringe, which assumes a flaxen or impure whitish gloss, not easily lost on 

 change of posture, but liable to spread, especially posteriorly, along the tips of the 

 longest hairs. Beneath, at the wing-roots, in both sexes, all the nervures, including 

 the inner border of the costa-root and the commencement of the inner margin 

 exterior to the alula, are beset with elongate, stipate scales, succeeded for some 

 distance by flattened hairs. Scales of the scape of the antenna brownish-black ; 

 hair of the flagellum whitish-grey. Pubescence of the body light grey, " shot " with 

 whitish on the notum and the ^ genitalia, and from most positions faintly yellowish- 

 tinted on the dorsum ; abdomen laterally, from a different standpoint, blackish. 

 Legs blackish or brown-black ; the tibial fringes and other hairs glossed with a 

 lighter colour ; the extreme apex of the femur and the scales at the apical margins, 

 dorsally, of the tibia and of at least the first joint in the tarsus, glossed with light 

 yellowish. Basal joint in the superior $ genital appendages relatively stout, slightly 

 curved, and rather longer than broad ; 2nd joint about twice as long, obliquely in- 

 flexed, gently curved, slenderly acuminate in its apical half. Season, May to July.

In the original diagnosis, one of the hair-spots of the wing was overlooked. 

 There are ten small black tufts in the region of the bristling hair — two at the forks, 

 and eight at the ends of the ranks of this hair. Beneath, at the base of the wing, 

 in both sexes, the distribution of scales and flattened hairs is nearly the same as in 

 P. morula. The colouring of the indumentum of the body, antennae, and legs, 

 resembles in general style of pattern that of the same species sufficiently to render 

 unnecessary a detailed specification of slight differences in tint ; the superior <? 

 genital appendages are likewise similar in form. Season, July. 



, A single ? of this species, associated with a ^ Psyclioda hmieralis, 

 stood for P. nuhila in Walker's collection— not owing to their being 

 at all alike, but more through his intelligible inability to perceive any 

 differences between them with bad lenses in the gloom of Bloomsbury, 

 than from any other conceivable cause. It is probably, therefore, not 

 exclusively a West of England species.
