M^Louis B. Prout on the 
brighter, the transverse lines slightly better expressed, sometimes 
Ijlackish-marked on the veins, the fringe less extremely long and 
more variegated with paler and darker, its basal line pinkish, not 
whitish. The hindtibia is perhaps less strongly thickened, but the 
surest structural distinction is in the antenna, which is well 
ciliated (the cilia in fine fascicles, their length nearly equal to the 
width of the shaft), whereas that of carneitincta is virtually simple. 
Zaiijon Amarilla (W. M. Bayne), type and another ^ in 
coll. L. B. Prout, both dated November 16, 1905—one, at 
least, at light; Puente del Inca (W. M. Bayne), a slightly 
worn $ in coll. A. F. Bayne. The dates, so far as available, 
suggest tliat S. ruhens occurs much earlier in the season 
than S. carneitincta (the former November, the latter 
February and March).

Salpis (Microclontopera) cudora, Prout, nov. sp. 
^. 38 mm. Pafiius with 3rd joint long (about 1 mm.), fusiform ; 
antenna with short, strongly clavate pectinations to beyond two- 
thirds, then serrate-dentate. Face grey; palpus whitish-grey, 
marked with fuscous, more strongly above ; antenna mostly ferru¬ 
ginous, its dorsal scaling grey ; legs whitish grey mixed with fuscous, 
the tarsi mainly fuscous, each joint tipped with whitish grey ; thorax 
and abdomen nearly concolorous with fore- and hindwing. Fore¬ 
wing with costa nearly straight, apex acute, distal margin weakly 
crenulate; brownish grey, coarsely irrorated with dark fuscous, 
browner on the veins and slightly darker-clouded in distal part; the 
lines fuscous; antemedian thick, from nearly one-third costa to 
beyond two-fifths inner margin, making strong outward curves in 
cell and in submedian area, the angles on M and SM^ accentuated by 
blackish dots ; postmedian from four-fifths costa, rather weak, but 
rendered prominent by a series of blackish vein-dots, each accom¬ 
panied distally by a pale vein-dot ; the dots on and on are 
placed more proxiniad than the rest of the series, and the line itself 
is lunulate between the dots ; a terminal series of small blackish 
dots between the veins; fringe nearly concolorous with wing, 
20 mm., which is the actual measurement of the largest specimen 
{rubens): — 
Costa. Inner margin. Distal margin.
