1. Triclonella xanthota, sp. n. (Tab. IV. fig. 32.) 
Antennae brown, annulate with whitish; the basal joint, small at the base expanding outwardly, with u 
white spot above its apex. Pulpi slender, recurved, the terminal joint not longer than the median ; 
brown, with two white longitudinal lines on the outer side of the median joint, and one along the under- 
side of the terminal joint, Head brown; face paler. Thorax brownish yellow. Forewinys yellow to 
two-thirds of their length, brown beyond, the change of colour abruptly defined, the inner edge of the 
brown apical portion obliquely convex toward the base, from the upper angle of the cell to the dorsum, 
the yellow encroaching upon it somewhat toward the costa; a small black dot on the cell, a little 
before the middle, and a yellowish spot beyond the end of the cell in the brown portion ; cilia brown. 
Exp. al. 18 mm. Hindwings and cilia pale brown. Abdomen pale brown. Legs brownish, the mediau 
pair with two white lines along the tarsi; the hind pair somewhat whitish on their inner sides. 
Type 2 (65936) Mus. Wlsm. (Godm-Salv. Coll.) BM. 
Hab. Mexico: GUERRERO: Amula, 6000 ft., VIII. (27. H. Smith). Unique. 
This species is very similar to pergandeella Busck in appearance and markings; it is 
however, larger, and differs in having a yellow spot on the brown apical portion of the 
forewings. 
9. Triclonella euzosta, sp.n. (Tab. IV. fig. 33.) 
Antennae fuscous at the base, and somewhat shaded with fuscous on the basal half, white beyond; with 
single hair pecten. Palpi slender, recurved, smooth, pointed, terminal joint as long as the median ; 
fuscous on their inner and outer sides, white above and beneath, with a white dot at the end of the 
median on its inner surface. Head smooth; shining, fuscous. Zhorax brownish fuscous. Forewings 
with the basal and apical fourths dark brown, the middle half occupied by a broad, bright, canary- 
yellow band, which, along the dorsum and at its two extremities, is bestrewed with shining silvery 
metallic scales, contrasting strongly with the adjacent dark brown colouring; cilia dark brown. 
Exp. al. 8 mm. Hindwings and cilia brownish grey. Abdomen and Legs shining, greyish fuscous ; 
spurs whitish.

ECBALLOGONIA, gen. n. 
(ée3d\\w=to throw out; ywvia=an angle.) 
Type: Ecballogonia bimetallica Wlsm. (Tab. IV. fig. 34.) 
Antennae %, minutely biciliate ; basal joint without pecten. Labial Palpi very slender, recurved, smooth ; 
terminal joint at least as long as median. Mawillary Palpt short, meeting over the base of the 
haustellum. Haustellum scaled at base. Ocelli present. Head smooth, covered with wide, flattened, 
scales, Thorax smooth. Forewings of even width throughout, except at the attenuate and pointed apex, 
which is in a line with the middle of the base: newration 12 veins; 7-8 stalked, 7 to slightly above 
apex ; the rest separate; 1-basally furcate. Hindwings 1, the costa rather depressed in the middle, 
apex not depressed, acute; termen very oblique, tornus suddenly rounded to the straight dorsum, flexus 
well-developed ; with distinct colour-pattern : neuration 8 veins; 6-7 separate and parallel ; 3-4 stalked ; 
5 cubital, midway between 4 and 6. Abdomen somewhat flattened. Legs short; the hind tibiae 
smoothly clothed, with projecting tufts above each pair of spurs; the inner spurs longer than the outer 
ones, those of the median pair longer than the distal.
