Megacraspedus exilis Wals. 
Texas, Alpine, 5000 • feet, April; 3 ex. These (all J) are 
certainly conspecific, and I have no doubt that they are identical 
with exilis, described from a single Mexican specimen, but there 
is considerable individual variation; in one example the head is 
grey with white sides ; the thorax is grey in two ; the forewings 
vary in development of grey irroration, the subcostal spot is incon¬ 
spicuous; the longitudinal dark streak is distinct in one, indistinct 
in one, and absent in one, and when indistinct or absent, the 
stigmata form distinct blackish-grey dots, plical very obliquely 
before first discal; the hindwings are grey-whitish or pale grey. 
Veins 6 and 7 of forewings rise near together out of 8. 
Aristotelia atacta, n. sp. 
3 . 15-16 mm. Head, thorax light greyish-ochreous. Palpi 
whitish, second joint fuscous except tip, terminal joint with tip and 
sometimes faint median ring greyish. Antennae greyish. Fore¬

irrorated whitish, especially towards costa, irregularly scattered 
black scales ; plical and second discal stigmata minute, blackish, 
hardly noticeable : cilia whitish-grey or ochreous-whitish, one or 
two faint greyish shades. Hindwings light violet-grey ; cilia pale

3 . 17 mm. Head, palpi, thorax pale ochreous, base of palpi

IDI0PTILA, n. g. 
Head with rather loosely appressed scales, sidetufts rather pro¬ 
jecting in front; ocelli small, posterior; tongue developed. 
Antennse |, in 3 filiform, minutely ciliated, scape rather elongate, 
without pecten. Labial palpi long, recurved, second joint thickened 
with dense scales forming a broad evenly long projecting tuft 
beneath throughout, terminal joint as long as second (base con¬ 
cealed), slender, acute. Maxillary palpi very short, filiform, 
appressed to tongue. Posterior tibiae clothed with very long fine 
hairs above. Forewings with tufts of scales on surface ; 1 b fur¬ 
cate, 2-4 curved at base, approximated from about angle, 5 and 6 
parallel, 7 and 8 stalked from transverse vein, 7 to costa, 9 from 
angle, 10 from near 9, 11 from ^ ; retinaculum of $ subradial, 
Hindwings 1, elongate-trapezoidal-ovate, apex pointed, termen
