tions of S 3. Thorax whitish, sprinkled with ochreous and dark 

 fuscous specks. Abdomeu grej-. Forewiugs elongate, costa 

 strougly arched, apex obliquel}' rounded off, term(m rounded, 

 nearly vertical ; in c? whitish with scattered fuscous and blackish 

 specks, in 5 light grey more or less suffusedly mixed with white 

 aud sprinkled with black ; a cloudy dark grey dot on end of cell ; a 

 short very oblique cloudy dark grey streak from costa before middle ; 

 an indistinct cloudy grey rntlier curved line from | of costa totornus; 

 marginal edge on posterior part of costa and apex tinged with 

 ochreous and irrorated with dark fuscous: cilia on posterior half of 

 costa pale brownish-ochreous, becoming whitish or grey-whitish 

 round termen and tornus. Hind wings grey, in S subhyaline in 

 disc, in 5 thinly scaled towards base ; cilia pale grey, with darker 

 subbasal line. 



Prench Gdiana, Godebert, La Forestiere, and St. Jean, 11. 

 Maroni, in April, July, and September ; five specimens. 



BAEONOMA, n. g. 



Head with appressed scales, sidetufts raised, spreading ; ocelli 

 present ; tongue developed. Antennae |, in S moderately or 

 strongly ciliated, basal joint moderate, stout, without pecten. 

 Labial palpi moderate, recurved, slender, with appressed scales, 

 second joint not reaching base of antenuse, terminal joint |-| of 

 second, pointed. Maxillary palpi very short, filiform, appressed to 

 tongue. Anterior tibite and tarsi very short, thickened with 

 scales, posterior tibiae clothed with rough scales. Forewiugs with 

 1 b furcate, 2^ jipproximated, 7 to termen, seldom 7 and 8 (leuco- 

 deltii) or 8 and 9 (holnn/a) stalked, 11 from middle. Hindwings 1 

 or over 1, trapezoidal-ovate, cilia f- 1 ; 8 and 4 connate, 5 some- 

 what approximated, 6 and 7 stalked. 



Type mastodes. Differs from Stenoma by the characteristic palpi, 

 and has also a peculiar facies and difterent form of wing, more 

 Oecophorid in character. To this genus must also be referred 

 lenco'ielta Meyr., notwithstanding the stalked veins 7 and 8 of 

 forewiugs (which led me to describe it erroneously as a Machimia, 

 the hindwings being somewhat injured), owing to its veryclose 

 specific relationship to eaiihanes. 



Baeonoma euphanes, n. sp. 



c? . 9-10 mm. Head dark fuscous, face centrally tinged with 

 prismatic whitish. Palpi dark grey, terminal joint white. Antennal 

 ciliations 4. Thorax dark fuscous, posterior half white. Abdomen 

 dark grey, anal tuft whitish. Forewiugs elongate, costa gently 

 arched, apex rounded-obtuse, termen rounded, rather strongly 

 oblique ; dark fuscous ; a short white mark on base of dorsum ; a 

 triangular white blotch on dorsum beyond middle, reaching half 

 across wing; apex narrowly white: cilia dark fuscous, white 

 round apex and towards tips on upper part of termen. Hindwings 

 rather dark grey, thinly scaled in disc ; cilia grey.
