tip and almost always at base, rarely with their whole superior surface pale 

 fuscous: the whole of tarsal joints 1 and 5, and the base of 2, and the tips of 2 — 

 4, all pale fuscous. Each femur 'S 9 is ciliated beneath with gray ciliations. 

 as long as but much more sparse than the hind fringe of the wings. Wings as 

 well as their veins, except the posterior branch of the 3rd longitudinal which 

 is whitish, pale fuscous from minute, ajjpressed hairs, except on the following 

 spots, where they are whitish-hyaline from the hairs becoming sparse, the pale 

 spots dominating the dark ground-color. — Between the 1st and 2nd longitudi- 

 nals, halfway to the tip of the wing, a large spot, twice as long as wide and ex- 

 tending from one vein to the other, and 2 subsemicircular spots with their diam- 

 eter resting on the costal and their circumference generally not quite reaching 

 the 2nd longitudinal, the first spot j of the way to the tip of wing and the last 

 close to the tip. Between the 2nd and 3rd longitudinals a triangular basal spot 

 extending to both veins and reaching to the point where the wing suddenly be- 

 comes wider: a large rhomboidal spot conterminous with the 1st or large costal 

 spot and only divided from it by the 2nd longitudinal which here as elsewhere 

 is pale fuscous ; a small, round, isolated spot i of the way to the tip of the 

 wing: and a large subtriangular spot commencing just beyond the small spot, 

 and extending to each vein laterally and to the terminal margin, except that it 

 abuts on the middle of its terminal boundary on a pale-fuscous, terminal spot. 

 Behind the, 3rd longitudinal 2 suhquadrangular spots — the first elongate and 

 subbasal, the second abbreviated and straddling the posterior branch of the 

 3rd longitudinal, and both of them extending from vein to margin with but a 

 narrow fuscous space on the basal and terminal side of each — and a triangular 

 spot occupying the terminal i of the space between the forks of the 3rd longi- 

 tudinal; making in all 10 spots, arranged in 3 rows. 3 and 4 and 3 in a row. 

 Ciliations extending all round the wing, as long but only about \ as dense on 

 the costa as behind. No cross-vein between the 1st and 2nd longitudinals. Ante- 

 rior branch of the 3rd longitudinal very distinct, and so nearly straight that 

 it describes a circular arc of about 25°. Neuration otherwise normal. — Length 

 (dried) % .05— .06 inch, J .06— .07 inch. Length wing % .07 inch, 9 .07— .10 

 inch.

 The oruamentation of the legs agrees almost exactly with that of D. 

 inaccux Lw., though from some cause or other, perhaps because the 

 le<>s were all mutilated, Loew omits all meution of the coloration of the 

 oth tarsal joint of that species; but the structure and coloration of the 

 antennae and the spottings of the wings are quite different in the two. 

 This is a most elegant species, and the spots of the wings are well de- 

 fined and bright, not obscure and indefinite as in 7-maru/ata.
