144. Cijclalima Elwesialis, nov. spec. (PI. XIX., 

 figs. 1, la). 



Three males of 33, 36, and 37 mm. expanse. 



For the geneiic characters of this species I refer to Lederer's 

 " Beitrag zur Kenntniss der Pyrahdinen," Wien. Ent. Mon., vii., 

 p. 897. They are all present and well-defined, though the Phycid- 

 like curve of the antennae, as Lederer calls it, is rather feeble, not 

 so conspicuous as in conchylalis ; besides, there is a tooth-like 

 projection on the fore side of the hamper of the antennae, just above 

 the basal article. The antennae are each inserted on a flat de- 

 pression, and, as in conchylalis, very minutely ciliated, pale 

 brownish grey, their basal article violet, with a coppery lustre. 

 Labial palpi only a good third longer than the head, the first 

 article sordid white, the other two, like the maxillarj'- palpi and 

 the face, violet with coppery lustre. Collar as the face, with a 

 whitish summit. Thorax and tegulse white, with some coppery 

 brown scales at their bases. Wings shaped as in conchylalis male» 

 the apex of fore wings less pointed and produced, the hind margin 

 not so straight and obhque ; hind wings more triangular. Colour 

 of wings white, somewhat transparent and glossy, with iridescent 

 reflections. Costa of fore wings deep greyish brown, more violet at 

 the base, and adorned with coppery metallic scales ; the grey- 

 brown attains the apex of the wing, narrowing gradually from the 

 base, where it occupies the whole basal half of the discoidal cell, 

 and is not so sharply defined, but more greyish than towards the 

 base ; a white spot at the half of the discoidal cell emarginates the 

 costal stripe a little, but a white more or less dark-edged lunule on 

 the transverse veinlet lies nearly totally outside of it ; hind margin 

 grey, about 2 mm. wide, inwardly well-defined and straight, not 

 attaining the anal angle of hind wings ; marginal line strong, 

 brilUantly metallic-grey, reminding the lustre of nickel ; it is not 

 perfectly continuous, and begins at vein 1 c of hind wings with the 

 grey border. Hind wings with a grey lunule on the disco-cellular. 

 Abdomen . whitish, with a long pencil-like anal brush of nearly 

 black hairs ; it is pointed, as the white one of conchylalis, not 

 expanded, as in the males of Phahellura. Under side of wings 

 nearly as above, the costa of fore wings darker than on upper side ; 

 cell 8 of hind wings also grey, but the hind margin and its metaUic 

 ornament less distinct ; ciliae greyish white. Legs sordid white, 

 the front side of the first pair coppery violet, with pure white tarsi. 



This species differs from conchylalis and laticostalis by 

 the narrower costa of fore wings, by the broadly grey 

 and brilliantly metallic-marked hind margin of all wings.
