perficially, but possessing the full structural characters of Jpodia, 

 which is a good genus (ueuration : fore-wings, 7 and 8 out of 6 ; 

 hind-wings, 3 and 4 widely remote, 5 nearer 6 than 4, 6 and 7 

 separate). 



ApODIA PSAMATniAS, W. Sp. 



(? ? . 9 mm. Head and thorax ocliroous-whitish, sprinkled with dark fuscous 

 Palpi whitish, second joint with sub-basal and broad subapical blackish bands, ter- 

 minal joint witli subapical blackish band. Antennoe whitish, annulated with dark 

 fuscous. Abdomen whitish-ochreous. Legs ochreous-whitish, banded with dark 

 fuscous. Fore-wings lanceolate ; whitish-ochreous, irrorated with fuscous and 

 blackish ; a dark fuscous dot at base ; a short, cloudy, dark fuscous mark from 

 costa near base ; six moi'c or less distinct, cloudy, dark fuscous or blackish dots, viz., 

 two on costa at one-sixth and one-third, two on fold somewliat obliquely beyond 

 these respectively, one (sometimes large) in middle of disc, and one in disc at 

 three-fourths ; cilia ochreous-whitish, with three partially interrupted lines of dark 

 fuscous scales (sub-basal, median and subapical). Hind-wings two-thirds, apical 

 projection two-thirds of breadth of wing ; pa^e grey ; cilia whitish-ochreous. 



Biskra ; two specimens. In neuration and other essential charac- 

 ters identical with the preceding, but very different superficially. 

 Here, as in most other species, diminution of size and paleness of 

 colouring are concomitants of the desert habitation. 



Calyptrotis, n. g. 



Head smooth ; ocelli present ; tongue well developed. Antennae three-fourths, 

 in (? serrulate, shortly ciliated, basal joint moderately long, densely scaled, with 

 dense pecten of long hair scales. Labial palpi long, recurved, with loosely appressed 

 scales, second joint long, terminal joint less than half second, pointed. Maxillary 

 palpi very short, appressed to tongue. Posterior tibise clothed with very long dense 

 hairs. Fore-wings with vein 1 long-furcate, 2 from two-thirds of cell, 3 from angle, 

 4 and 5 approximated at base, 7 and 8 stalked, 7 to costa, 11 from middle of cell. 

 Hind-wings four-fifths, trapezoidal, hind-margin deeply sinuate beneath pointed 

 produced apex, cilia 2 ; veins 3 and -i remote, 5 approximated to 4 at base, 6 and 7 

 widely remote and parallel. 



This genus, structurally related to Monochroa, is immediately 

 separated from that and all its nearest allies by the strongly de- 

 veloped and conspicuous scale-peel en of the basal joint of antennae, 

 which in them is entirely absent. The very short terminal joint of 

 the palpi is also a noticeable character. 



C. ALPHITOUES, n. sp. 



(J fj . 13 — 16 mm. Head white, with a few black scales. Palpi white, more 

 or less irrorated witli black externally. Antenna; white, annulated with black. 

 Thorax white, sprinkled with black, apex of patagia and posterior extremity black. 

 Abdomen whitish. Legs white, banded with black irroration. Fore-wirgs lan- 

 ceolate ; white, more or less tinged with pale greyish-ochreous in disc, and irregularly 

 irrorated throuj^iiout with black ; tlie increase of this irroration tends to form two
