138 HETEROCERA. 
Most nearly allied to Macrobathra Meyr. and Gymnobathra Meyr., which agree in 
having FW: 7 to costa and no antennal pecten, but at once distinguished from both 
by the peculiar clothing of the hind tibiae. In general appearance Echallogonia 
reminds one most strongly of Petalanthes Meyr., which however differs in its less 
pointed hindwings and by having FW: 7 to termen. 
1. Ecballogonia bimetallica, sp. n. (Tab. IV. fig. 34.) 
Antennae fuscous, whitish at the base beneath. Palpi silvery at the sides, fuscous beneath. Head fuscous ; 
face with two lateral silvery streaks. Jhorax tawny fuscous, anteriorly collared with steel-grey, tegulae 
sieel-grey except at their base.  Forewings tawny fuscous, with some elongate central shades of 
ochreous and many steel-grey spots aud lines; a steel-grey spot near the base of the dorsum extends to 
the fold and is followed by a similar oblique metallic streak from fold to dorsum at one-fifth from the 
base; a small steel-grey costal spot, a little beyond the first dorsal spot, emits a broken subcostal line of 
steel-grey scales reaching to a whitish mediocostal spot ; a dark steel-grey metallic line along the cell 
terminates a little above the apex, a second line, commencing about the middle, diverges in a broken 
series of scale-spots around the termen to the apex, ending in a short metallic apical streak ; cilia tawny 
greyish fuscous along their base. Exp. al.12 mm. Hindwings dark tawny fuscous, with a straight, 
narrow, whitish central transverse band, wider on the costa than on the dorsum, preceded by a patch of 
steel-grey metallic scales and followed by a line of the same extending to the apex parallel with the 
termen; cilia tawny greyish; the white band is very visible on the underside, accompanied by some 
metallic scaling. Abdomen shining, bluish grey; whitish beneath at the base. Legs tawny fuscous, 
with two white bands around the hind tibiae at the base of the whitish spurs; a single white spot on 
the second tarsal joint.

Hab. Mexico: vera crtz: Atoyac, 1V. (1. H. Smith). Unique. 
NECEDES, gen. n. 
Type: Necedes stigmaphylli Wlsm. (Jamaica). 
Antennae almost as long as the forewings, biciliate ; basal joint without pecten. Labial Palpi long, recurved, 
smooth, rising high above the vertex; terminal joint acute, nearly as long, or longer than median. 
Mawillary Palpi short, converging. Haustellum well-developed. Ocelli absent. Head with strong side- 
tufts, meeting above. Thorax smooth. Forewings widening from the base to vein 12, thence gradually 
narrowed to the depressed apex, beneath which the termen is strongly excavate at vein 6, below which 
it becomes convex to the dorsum: neuration 12 veins; 7-8 stalked, 7 to costa; 2-4 closely approximate 
at end of cell, 8-4 connate; 4 and 5 curving widely apart toward termen, where 5 becomes closely 
approximate to 6; upper fork of 1 subobsolete. Hindwings —1, the costa somewhat depressed in the 
middle, termen oblique: neuration 8 veins ; 6—7 separate and parallel ; 3-4 stalked; 5 cubital, approxi- 
mate to 4. Abdomen slightly depressed. Legs: hind tibiae hairy above. 
[Necedes stigmaphylli, sp. n. 
Antennae pale cinereous, annulate with brown. Pali recurved, acute, with long terminal joint ; chestnut- 
brown, becoming whitish toward the apex, with a fuscous ring immediately preceding it. Head greyish 
brown, Yhora# chestnut-brown, with a whitish bar posteriorly. Forewings pale brownish ochreous, 
suffused with dark chestnut-brown, especially at the flexus, on the oblique cuneiform fascia at one- 
fourth, on the end of the cell, and along the costa before the apex; from the base of the costa a mottled 
and streaky pale greyish shade extends obliquely outward to the dorsum at one-third, containing some 
brown spots ; this is followed by the suffused cuneiform fascia which sends out two points on its outer 
side, one along the dorsum and one above it, the upper one bounding the lower edge of a conspicuous whitish 
costal patch, also dilated outward at its lower edge, and there somewhat tinged with ochreous—this 
contains on the cell a blackish dot; the suffused patch which succeeds it is connected to the costa by a 
rather paler chestnut-brown shade, through which runs a steely grey streak, starting from a white costal
