line, forming a triangular spot of grey suffusion beneath apex, and 
marked two black dots below middle: cilia grey-whitish with dark 
grey subbasal line, metallic-shining below middle of termen. Hind- 
wings whitish-grey, a grey marginal line round apex ; cilia whitish. 
Argentina, Alta Gracia ((7, Bruch) ; 1 ex. Allied to azanctlis. 
The labial palpi of Diptychophora vary much in length, scaling, and 
direction, of which no account is taken by Hampson, who simply 
calls them “ porrect, clothed with long hair and extending about 
the length of head,” although Zeller in his description of the type- 
species quite correctly says “ slender, ascending.” They vary to 
three times the length of the head, and even the long ones are 
sometimes strongly ascending, w r hilst the scaling (as in the type- 
species) may be closely appressed. I consider that all these forms 
are correctly included in the same genus, always definable by other 
structures and truly homogeneous, and indicated by these points as 
an early form of the family. 
HYPONOMEUTIDiE. 
Hyponomeuta hemileuca, n. sp. 
<$ $ . 16-18 mm. Head white. Palpi black, tips of joints 
mixed white. Thorax white, anterior margin, a mark on shoulder, 
and two dorsal spots black. Abdomen grey. Forewings elongate, 
costa gently arched, apex obtuse-pointed, termen slightly rounded, 
oblique ; smooth ashy-grey, dorsal half suffused white ; 6 variable 
black dots just beneath costa from near base to beyond middle, 
a series of 6-8 large black dots above fold throughout, and a series 
of 5-6 others above dorsum from near base to near tornus : cilia 
pale grey. Hindwings dark grey ; a hyaline space beneath basal 
half of cell; cilia grey, paler on outer half. 
Uganda, Busana, April (Cr. L. B. Hancocic); 8 ex. (type Brit. 
Mus.). A distinct species. 
TEICHQCIRCA Meyr. 
I am now of opinion that the recently published genus Telosphrantis 
Meyr. (type aethiopicci Meyr.) is not sufficiently distinct from Tricho- 
circa, and should be merged in it. 
Ethmia phoenicura, n. sp. 
5 . 22 mm. Head white, collar metallic dark green-blue. 
Palpi white, second joint blackish towards base. Antennae purple- 
blackish, scape white. Thorax white, a dark green-blue posterior 
spot. Abdomen grey, anal segment crimson. Forewings white ; 
markings metallic dark green-blue ; four slender transverse fasciae, 
first near base, second before 3 , slightly oblique, these two connected 
by a costal streak extended to base, third median, fourth from | of 
costa to dorsum before tornus, each of these broken into three spots, 
central spot posterior, the costal spots transverse and connected on 
costa, an additional spot from costa at ; a small round spot in
