PHYSETOBASIS; POMASIA; EUPITHECIA. By L. B. Prout. 



conspicua- 



ria. 



somewhat blunted), both wings with small black discal dot and extremely broad reddish median band (on the 

 hindwing much paler in Japanese specimens), its distal edge on the forewing arising at two-thirds of costa 

 but running obliquely outwards (with one projection midway) so as to touch the distal margin at the 'd'^ radial, 

 then again nearly at the 1" median, finally running in a curve to hindmargin near the angle. Underside much 

 more weakly marked. Oiwake, Japan. Described from Assam. 



C. conspicuaria Leech (12 b) has the distal area more yellowish and quite differently shaped, both wings 

 with characteristic angular discal marks, that of the forewing yellow, that of the hindwing black. Omei-shan, 

 W. China, in July; only the type (?) is known. 



denti fascia. 



71. Genus: Physetobasis Hmps. 



Structure similar to that of Asthena, but the shape very different, more like that of the succeeding 

 genera. Forewing long and narrow, distal margin strongly oblique. Hindwing also rather narrow, but not 

 long, distal margin somewhat crenulate. In the cf the retinaculum is usually developed into a large spatulate 

 plate and the type species [amiulata Hmps.) shows further secondary sexual modifications. Discocellulars of 

 hindwing strongly oblique, variable, sometimes distinctly angulated at the origin of the 2"'' radial. 



A small Indian genus. 



P. dentifascia Hmps. {= mandarinaria Leec7«) (Hi, as mandarinaria). Forewing brown, the lines black, 

 white edged, thickened at costal margin; their very characteristic form is well shown in our figure; sometimes 

 there is also a weak dark central shade. Hindwing with distal margin scarcely crenulate, discocellulars angulated; 

 paler, at least anteriorly; distal area nearly as that of forewing. Dharmsala and W. China. A weakly marked 

 ? from Kiukiang perhaps indicates a local race. 



72. Genus: Pomasia G 



uen. 



denti- 

 chthriila. 



General characters as in Eupithecia but the abdomen not crested, the coloration in general more gay, 

 the hindwing less regularly rounded (typically somewhat bent at 3'''^ radial), with 2"'' discocellular somewhat 

 curved inwards, thus with a very slight angle at the origin of the 2""^ radial, which is central. Palpus with 

 both the 2"'' and the S^*" joint long, rather strong, but shortly scaled. 



An almost exclusively Indo-Australian genus, of which one species has recently been discovered in Japan. 



P. denticlathrata Warr. (13 m). Pale ochreous yellow, traversed by very numerous (on forewing about 

 15, on hindwing about 9) undulate liver-coloured lines, which are mostly thicker than the interspaces of the 

 ground-colour and are in places connected; the yellow colour is slightly darkened in the distal area. Fringes 

 dark-spotted, the spots opposite the 3'''* radial and 2""^ median somewhat enlarged. Underside more orange- 

 coloured, very weakly marked except at costal edge of forewing, which is fuscous and yellow spotted. Described 

 from the Naga Hills, afterwards taken in the Khasia and more recently by Wileman on Kiushiu: Kagoshima 

 in July, Kiyotaki in September. 



73. Genus: Eupitliecia Curt. 



Small or (rarely) middle-sized moth, never large. Face with cone of scales or merely roughened. Palpus 

 moderate to long. Antenna of cf simply ciliated. Hindtibia with all spurs. Abdomen with minute dorsal crests. 

 Forewing rather elongate, with areole generally single. Hindwing relatively short, discocellulars not biangulate, 

 not very oblique, 2"'' radial arising in the centre, d^ with 8"' abdominal segment widened into a tube which 

 encloses the copulatory organs, the sternite and tergite of this segment with characteristic chitinized plates. 



Egg more or less oval, the sculpturing variable but commonly consisting of a network of irregularly 

 shaped cells; duration of this stage generally short. Larva variable in form, very commonly with a lozenge- 

 shaped dorsal pattern and feeding on flowers. Pupa usually hibernating in an earthen cocoon. 



A very extensive genus, distributed almost throughout the world and generally very easy to recognize 

 by its shape and aspect, even apart from the structure. The species with the areole double are regarded by 

 Meyrick as belonging to a separate genus Encymatoge Hbti., but they do not form a natural assemblage and 

 I have not even separated them off as a subgenus, but have followed the arrangement of Dietze, the world-
