NOVITATES ^OOLOGICAE XXI. 1914. . 405 



10. Arenostola rufula spec. nov. 



Tliis species is abotit the same size and narrowness as pkraqmitUlis, agreeing 

 in coloration with the ab. rufescens Tntt, but here again the fringe of forewing is 

 unicolorons, and the costal edge is white ; the hindwings are pale ochreous at base, 

 becoming rufous ochraceous in terminal halt, with the fringe beyond it paler ; 

 the head and thorax are pale rufous, concolorous with the forewing. 



1 ? from the Tedschen Oasis, Transcaspia, taken along with the previous 

 species, and I S (type) from Baigacum, Syr-Daria (Koshantschikoff). 



Subfamily ERASTRIANAE. 

 11. Hyposada assimilis spec. nov. 



Forewing : yellow, varied with dull red ; the costal edge narrowly white to 

 beyond outer line ; a subcostal olive-fuscous streak speckled with black ; lines 

 of the yellow ground colour ; the inner vertical, waved, inangled in cell ; the outer 

 denticulate, excurved round cell, then incurved, approaching inner line on sub- 

 median fold; median fascia tilled in with olive fuscous above middle and dull pink 

 below; subterminal line lunnlate, yellow, followed by a grey clond limited inwardly 

 by blackish wedge-shaped or triangular marks ; space preceding it with dull red 

 double streaks on the veins connected by a curved red line, mixed with grey below 

 middle ; terminal area yellow mixed with grey and red scales ; a row of black 

 terminal triangles ; fringe grey intersected with yellow ; a snow-white cell-spot 

 edged with black scales. 



Hiiidwing : similar ; the cell-spot black. 



Underside ochreous with dark grey markings and black spjts. 



Face and palpi olive brown ; vertex ochreous ; tegulae snow white with a 

 dark brown line at base ; thorax and abdomen pink and yellow ; venter and 

 legs ochreous. 



Expanse of wings : .30 mm. 



1 cJ from Arizan, Kagi district. Central Formosa, July 1908. 



Resemblesya^ewsa Moore, but smaller and duller ; the markings less oblique. 



Genus Lepidopyrga gen. nov. 



Distinguished from Stenoloba Stgr. by the whole thorax bearing an immense 

 erect crest of spatulate scales ; the forewing longer and narrower, with eosta 

 straight and parallel to inner margin ; termen more vertical ; tufts of scales in cell 

 more developed ; the only species altogether more robust. 



Type, L. viriclimicta Hmps. 



12. Lithacodia larentifoi'mis ab. albiterminata ab. nov. 



Differs from the type form, in which the whole of the terminal area beyond 

 outer line is grey-brown, in having the narrower terminal border only beyond 

 ■subterminal line grey-brown, the space between outer and subterminal lines white ; 

 this form occurs in both sexes ; Moore evidently thought these all males and the 

 typical form females only (see Moore, Lep. At/t., p. 142). The resemblance to 

 fuscula which he notices is much more striking in these whitish marked specimens 

 than in the browner type form.
