anal angle. The is darker, the light markings contrasting, the 9 is lighter, the markings not prominent. Ari¬ 
zona (Cochise County). 
10. Genus: Ifiacora Dyar. 
Veins 1 and lb of forewing distantly separated, 2—5 arise from the lower cell-angle, discal vein forked; 
G from the cell-apex; areole small, half of its length projecting beyond the discal cell. 7—9 stalked from it, 10 
above it, 11 from the discal cell near the base. On the hindwing the cell projects far, the discal vein is not 
forked, 7 and S are separated, but nearing each other. The frenulum is only small in the <$, or absent altogether. 
Type: M. tropicalis Schs. 
M. tropicalis Schs. (183 c) is a large whitish grey species with dark shading through the centre, so that 
more purely whitish areas appear basally and apically, with fine and coarse striated reticular markings; the 
coarse ones form an X-shaped marking in the marginal area. antennae plain, flattened. British Guiana (Omai). 
M. diffidens Dyar (181 h) is smaller and darker than tropicalis with the same formation of the antennae, 
the two lines in the distal area of the forewing are bent and about parallel, not crossing each other. Mexico 
(Zacualpan). 
M. adolescens Dyar differs from diffidens in coarsely and shortly serrated antennae in the A- Tl ie wing 
is shaded darker; the distinct black lines in the distal area are separated and almost parallel, distantly remote 
from each other. Panama (Taboga I.). 
M. subtropicalis sp. n. (183 c). As in the following species, the <$ has here bipectinate antennae. Dark 
grey, reticularly striated with fine and coarse black lines; a distinct line from the exterior third of the costal- 
margin to the lower third of the distal margin; right behind the middle two lines form an X-shaped marking 
extending from the costal margin to the inner margin. Hindwing grey. San Salvador, Guatemala; type in 
the U. S. National Museum. 
M. perplexa Neum. <P Dyar (181 i) is not at hand, but the figures of Barnes & Mod. are excellent. Fore¬ 
wing grey with a silky gloss, very finely reticulated, a Y-shaped forked line almost in the middle, another one 
in the distal area. Hindwing monotonously light grey with a silky gloss. Colorado and Arizona. 
M. leucegchytes Dyar (183 c) is smaller than perplexa, the striation still finer, the dark exterior lines 
differently placed. Mexico (S. Luis Potosi). 
M. luzena Barnes (181 b). A smaller species, marked like leucegchyta, but the striation coarser. Only 
99 known. The formation of the A antennae therefore does not allow for the present to fix the position de¬ 
finitely. Arizona (Cochise Co.). 
11. Genus: I*sycliopsis gen. nov. 
A small species with triangular wings. Forewing with veins 1 and lb separated, 2—5 arise from the 
lower cell-angle; discal vein forked; 6 from the upper cell-angle; 7—9 stalked from the end of the small areole, 
10 from it and 11 far back from the discal cell. Cell of hindwing very long, especially the lower angle far produced, 
veins 3 -5 short, the discal vein shortly forked; 6 and 7 separated, but very close together from the upper cell- 
angle, 8 free. Antennae of A bipectinate, the $ with a slender, rather long frenulum-thorn. Only 1 species. 
C. infantilis Schs. (182 g). Small, black, resembling a Psychid; forewing clouded somewhat lighter and 
with indistinct fine and coarse linear striae, the coarse ones forming an irregularly forked line in the marginal 
area. Only 1 A known. Costa Rica. 
12. Genus: €hilecoma<lia mv. 
Veins 1 and lb of forewing separated, the cell uniformly rounded, veins 2—6 arising at equal distances, 
the dis‘cal vein long forked; veins 7- 10 from the small areole, 7 and 8 on a short stalk, 11 from the centre of 
the discal cell. Hindwing likewise with a rounded cell, veins 2—7 all separated and at equal distances, 8 free; 
discal vein forked. Antennae of $ serrated on one side. S with a long thick frenulum. 
Type: Ch. moorei Silva Figueroa. 
Ch. moorei Silva Figueroa (183 c). Light grey, the disc often tinged with greenish, with fine lines and 
large coarse dark striae. Hindwing light grey, interruptedly reticulated. Both sexes similar. Chile. Bred by 
Dr. Silva in great numbers from trunks of willows, a large series from this breeding in the National Museum 
at Washington.
