PuU. 17. V. 1915. XYLOSCIA ; ARTEMIDORA; ARTIORA; AUAXA; CORYPHA. By L. B. Prout. 329 



47. Genus: Xyloscia Warr. 



Pace smoothly scaled. Palpus moderate or longish, with moderately appressed scales. Antenna in 

 both sexes bipectinate, in the ^ with long branches. Femora somewhat hairy. Wings not very robust, smoothly 

 scaled. Forewingwith distal margin prominent in middle; 1st and 2nd subcostals free. Hindwing costa elon- 

 gate, apex cut away, a point at end of 2nd subcostal, distal margin rather sinuous, slightly prominent at 3rd 

 radial. Only two sp3cies are known, both Palearctic. 



X. subspersata Feld. (16 d). Light wood-colour with browner markings, the postmedian Ime on the suispersata, 

 hindwing black. Black discal dots (at least on the hindwing) and sometimes a black spot in the middle of 

 the brown submarginal band of the forewing. The dentate distal edge of the obHque postmedian band is 

 distinctive. Japan. 



X. biangularia Leech (16 d) is rather browner, with darker lines, the antemedian of the forewing sharply biangularia. 

 biangulate, approaching the cell-dot, the distal edge of the postmedian band blacker, not dentate. Central 

 China: Chang Yang. 



48. Genus : Artemiclora Meyr. 



Related to Selenia and Phalaena but more slenderly built, pectus less densely hairy, antenna in $ 

 slender, scarcely subserrate. Forewing broader than in Selenia, the bend in the distal margin not very pronounced 

 in the ^, much more so in the $; a transparent discocellular mark; 1st subcostal vein anastomosing with costal 

 and with 2nd subcostal (in Phalaena generally free), 2nd subcostal often also with 3rd — 4th; 1st radial not 

 stalked. Hindwing ample, with a strong angle or tooth at the end of the 1st median. $ smaller than ^. Only 

 the tjrpe species is known. 



A. maracandaria Ersch. (16 d). Easily known by the shape of the wings and of the darkened median maracan- 

 area of the forewing. Hindwing more mixed with ochreous than forewing. Underside heavily dark-irro- dana. 



rated. Zerafshan to the Hi district. 



49. Genus: Artiora Meyr. 



Face with short projecting scales. Palpus short. Tongue short. Antenna in ^ bipectinate, in $ almost 

 simple. Abdomen rather robust. Forewing without fovea; rather narrow, distal margin slightly crenulate, 

 with a deep excision between apex and 1st radial; 1st and 2nd subcostals coincident. Hindwing with costa rather 

 elongate, distal margin crenulate. — Larva stout, somewhat flattened, without protuberances. — This genus 

 also consists of a single species. 



A. evonymaria Schiff. (= obscura Aigner) (17 b). Variable in colour. The first figured form, which, evonymaria. 

 becomes the nomenclatural type (Hbn. 31), has the forewing and the distal part of the hindwing somewhat 

 infuscated — not a very successful figure but certainly depicting the ,, coffee-brown" (violet-brown) form of 

 AiGiSTER. — ab. flavescens ah. nov. (16 d as evonymaria) is the commoner, more ochre-yellowish form only in fyavescens. 

 the ^ somewhat more reddish than in the ^. — ab. fuscaria Wagner (= exquisita Aigner) is almost uniform fiiscaria. 

 dark brown, darkest distally to the fine pale line which accompanies the postmedian dots. — Egg oval, granu- 

 lated and pitted, shining brownish grey. Larva slate-grey with longitudinal yellow lines or rows of spots partly 

 filled in with deep orange or red-lead. On Euonymus in May. The moth in July — September; only known 

 from Germany and Austro-Hungary. 



50. Genus: Auaxa Walk. 



Palpus short. Antenna in both sexes simple. Femora somewhat hairy. Forewing with apex acute, 

 distal margin gently crenulate, somewhat prominent in middle; 1st — 2nd subcostal long-stalked, their stallv 

 anastomosing at a point or connected with the costal, the 2nd later connected with the 3rd — 4th; discocellu- 

 lars angled mwards. Hindwing with distal margin gently crenulate. Only one species known. 



A. cesadaria Walk. (= sulphurea Btlr.) (16 d. as^sulphurea). Yellow, the markings reddish. Ante- cesadaria. 

 median line of forewing usually indistinct; postmedian oblique; distal area of forewing broadly reddish; fringe 

 with dark spots. Japan and Korea to W. China. 



51. Genus: Corypha Walk. 



Similar to Auaxa and to Angerona, but with the palpus long, with long, exposed Std joint. Forewing 

 with 1st subcostal free, 2nd free or often anastomosing with 3rd — 4th. 



C. incongruaria Walk. Ochreous, much less yellow than the preceding species, distal area not appre- incongn- 

 ciably redder. Further distinguished by the fme but well-expressed darker lines, the antemedian strongly 

 angled, the other two only a little sinuous, continued on hindwing. N. China, Yokohama and Kiushiu.
