Fore wings elongate, costa gently arched, apex obtuse-pointed, 
termen very obliquely rounded; pale ochreous suffusedly irrorated 
grey ; stigmata moderate, dark fuscous, plical slightly before first 
discal, second discal connected with dorsum by a dark fuscous bar ; 
a hemispherical dark purplish-fuscous blotch on costa somewhat 
beyond middle, preceded by a small pale ochreous spot and followed 
by a larger one; an apical blotch of dark purplish-fuscous suffusion:

GNATHQTONA, n. g. 
Head loosely haired; ocelli posterior; tongue short. Antennae f, 
3 serrulate, simple, scape elongate, without pecten. Labial palpi 
second joint extremely long, straight, porrected, with rough 
projecting scales above diminishing to apex, terminal joint | of 
second, slightly ascending, slender, somewhat pointed. Maxillary 
palpi rudimentary. Foretvings 2-4 approximated from angle, 
7 and 8 stalked, 7 to costa, 11 from before middle. Hindwings 1, 
elongate-ovate, cilia nearly 1 ; 2 from 3 and 4 stalked, 5-7 
parallel. 
A development of the Cryptolechia group. 
Gnathotona thermopsamma, n. sp. 
3 . 17 mm. Head, thorax whitish. Palpi grey-whitish, 
sprinkled fuscous. Fore wings elongate, costa gently arched, apex 
pointed, termen very obliquely rounded; ferruginous-ochreous;

Paraguay, Santa Sofia ( Reimoser ); 1 ex. (Vienna Mus.). 
CHAHADRAULA, n. g. 
Head with appressed scales ; ocelli posterior ; tongue very short, 
slender. Antennae |, scape rather elongate, without pecten. 
(Labial palpi missing, probably approximating to Apiletria .) 
Maxillary palpi rudimentary. Forewings 1 h short-furcate, 2 from 
near angle, 3 from angle, 7 absent, 11 from before middle. 
Hindwings 1, elongate-ovate, cilia nearly 1 ; 2 from f, 3 and 4 
connate from angle, 5 parallel, 6 absent. 
Allied to Apiletria. Notwithstanding the loss of palpi, this 
genus appears sufficiently recognisable.

elongate, rather narrow, costa gently arched, apex obtuse-pointed, 
termen very obliquely rounded; brownish-ochreous, undefined
