EXOTIC MICROLEPIDOPTERA. 
the apex more obtuse, the termen absolutely without sinuation, the 
subterminal line represented by a rather curved series of faint dots, 
the hind wings much lighter, with yellower cilia. Walsingham 
(Biol. C.-Am. iv, 153) records T. directrix from Costa Bica, on the 
authority of Mr. Busck ; it is more probable geographically that th© 
species intended is geranomorpha. 
Falculina caustopis, n. sp. 
3.29 mm. Head, thorax greyish-fleshcolour sprinkled blackish- 
grey, face whitish with orange sides. Palpi pinky-whitish, second 
joint orange with lateral streak of infuscation on upper half. 
Abdomen grey, beneath whitish. Forewings elongate, somewhat 
dilated, costa moderately arched, apex falcate, termen concave, 
somewhat oblique ; 7 and 8 closely approximated towards base ; 
brown with faint pinkish tinge, cell and dorsal area beneath it 
suffusedly mottled blackish-grey, terminal area beyond cell suffused 
smoky-grey ; costal edge fulvous ; a faint grey angulated subterminal 
line indicated opposite apex ; a terminal series of blackish-grey 
dots : cilia grey, on costa brownish. Hindwings orange ; a moderate 
dark grey terminal fascia throughout; cilia light grey, a darker 
subbasal shade. 
Brazil, Teffe ( Plason ); 1 ex. (Vienna Mus.). 
Loxotoma seminigrescens, n. sp. 
$. 37 mm. Differs essentially from L. eiegans only in the 
hindwings; these are rather dark grey on basal half, becoming 
brownish-rosy posteriorly, and veins 3 and 4 are stalked for -J of 
their length (in eiegans connate). 
Brazil, Petropolis ( J. G. Foetterle) ; 1 ex. (Vienna Mus.). 
KHYHCHOPHYLLXS, n. g. 
Head with appressed scales, forming a projecting tuft on forehead; 
ocelli posterior; tongue developed. Antennae hardly $ filiform, 
scape short, without pecten. Labial palpi very long, straight, 
porrected, second joint very long, much thickened with dense rough 
scales above and beneath, terminal joint short, rough-scaled, obtuse. 
Maxillary palpi rudimentary. Posterior tibiae loosely scaled. 
Forewings 2 from angle, 3 absent, 2 and 4 approximated, rather 
curved, 5 approximated, straight, 7 and 8 stalked, 7 to termen, 
11 from middle. Hindwings 1, trapezoidal, termen slightly sinuate, 
cilia | ; without cubital pecten ; 2 from about 3 and 4 short- 
stalked from angle, 5 near and approximated at base, 6 and 7 
short-stalked. 
A highly peculiar insect; the hindwings are normal for the 
Xyloryctidce , to which therefore it must be referred, but the rest of 
the structure is very abnormal; possibly there is some relationship 
to Falculina , which is suggested by the superficial appearance, but 
this may be delusive.
