194, MR. F. WALKER ON HETEROCEROUS LEPIDOPTERA 
Antenne contortz, dilatate, spatulate, apice serratee. Abdomen alas 
posticas vix superans, Pedes validi; tibize posticz pilis longissimis 
dense vestite. Ale antic sat anguste, apice subrotundatz, costa 
recta, margine exteriore perobliquo. 
Male. Body moderately stout. Head with a prominent acute frontal 
tuft. Proboscis short. Palpi small; 2nd joint obliquely ascending ; 
3rd porrect, less than half the length of the 2nd, with which it forms 
a slight angle. Antennz somewhat spiral, dilated from the base to 
one-third of the length, beyond which they are more dilated and some- 
what cup-shaped; apical part serrate. Abdomen hardly extending 
beyond the hind wings. Legs stout; hind tibie thickly clothed with 
very long hairs; spurs of moderate length. Wings rather narrow. 
Fore wings slightly rounded at the tips; costa straight; exterior bor- 
der very oblique. This genus seems to connect the Hadenide with 
some of the genera of the Herminide. 
258. SERIA CYATHICORNIS, n.s. Mas. Rufescens, antennis ex parte 
nigris, alis anticis lineis tribus indistinctis denticulatis nigricantibus, 
linea submarginali e guttis nigricantibus, reniformi ex annulis duobus 
connexis cinereis, alis posticis eneo-fuscis. 
Male. Reddish, with a cinereous tinge beneath, Antennx with the 
cup-shaped part black. Fore wings with three indistinct blackish 
denticulated lines; submarginal line formed of blackish dots ; reni- 
form mark composed of two cinereous connected ringlets with black- 
ish disks, the fore one much smaller than the hind one. Hind wings 
eeneous brown; fringe cinereous, shiming. Length of the body 5 
lines; of the wings 6 lines. 
Gen. NEBRISSA, 0. g. 
Mas. Corpus crassum. Proboscis mediocris. Palpi erecti; articulus 
3°5 conicus, parvus. Antenne vix crenulate. Abdomen depressum, 
alas posticas superans, fasciculo apicali compresso. Pedes validi, pi- 
losi. Ale@ antic apice rotundate, costa recta, margine exteriore vix 
obliquo. 
Male. Body thick. Proboscis moderately long. Palpi erect, rising as 
high as the vertex; 3rd joint conical, less than one-fourth of the 
ength of the 2nd. Antenne very minutely crenulate. Abdomen 
depressed, extending somewhat behind the hind wings; apical tuft 
compressed. Legs stout, pilose; hind tibiae with one spur in each 
pair full twice the length of the other. Wings moderately broad. 
Fore wings rounded at the tips; costa straight; exterior border very 
slightly convex, hardly oblique. 
This genus hardly belongs to the Hadenide.
