18 lOTAPHORA; OHLOROMAOHIA ; OOHROGNESIA. By L. B. Protjt. 



ma7idari- H. mandarinaria Leech (1 i) is related to albovenaria, the margins of the ■wings not crenulate, the veins 



nana, j^q^- marked by white. Antemedian Une shghtly curved, postmedian broad, rather straight, shghtly obHque; an 



elongate whitish cell-mark which is not present in any other species of Hipparchus. Under surface of forewing 



partly, of hindwing largely whitish. West China : Chow-pin-sa. One ^, taken in June, in coll. Brit. Mus. Recently 



also recorded from Hondo and Yezo (Japan) in April and July by Wilbman. 



valida. H. valida Feld. (= dioptasaria Christ.) (li). A very large species, shaped somewhat as albovenaria 



but Avith the irregularities in the wing-margins exaggerated, the markings also nearly as in albovenaria but 

 more slender, the veins not broadly white. Under surface similar to upper. Amurland to Korea and Japan, 

 appearing about midsummer. 



vallata. H. \ aWaia Btlr. {Ih). Considerably smaller than the other species, and at once distinguished by a dark 



spot in the fringe at the end of the third radial of hindwing. Probably nearest to glaucaria, which it resembles 

 in the white-banded underside; forewing with distal margin less oblique, hindwing longer, with rather more 

 marked tail, lines on forewing straighter, parallel, costa of forewing dark-speckled. Common in Japan from 

 June to August; also known from Sikkim. 



14. Genus: lotaphora Warr. 



Palpus moderate, with third joint small. Antenna in ^ bipectinate. Hindtibia in ^ dilated, with hair- 

 pencil. Abdomen not crested. Wings smooth-scaled, iridescent. Forewing with first subcostal free. Hindwing 

 with second subcostal from near end of cell. Only two species are known, so nearly related that they have some- 

 times been taken to be forms of a single species. The name-type of the genus, iridicolor Btlr., belongs to North 

 India, the second species, which is here figured, represents it in the Palearctic region. The moths are very dis- 

 tinct in facies from any others known, but in structure they present b\it few differences from Hipparchus, 

 to which, moreover, Grab see compares the larva of admirabilis. 



adimrabilis. I. adtiiirabilis Ob. (li). Differs from iridicolor in having stronger and sharper markings, with the 



distal area more differentiated in colour from the rest of the wing, cell-mark of forewing rather shorter, post- 

 median hne of hindwing straighter. The larva feeds on Juglans mandchurica, on which it was discovered by 

 Grabsbr, who describes it as light green, deceptively like a young, half-expanded leaf of the foodplant; head 

 produced into two points, body contracted; rests rigidly attached by the prolegs to a twig. Pupates in a loose 

 cocoon among diy leaves, and the imago appears in the second half of July, and in August, frequenting damp, 

 densely wooded places, from western China to Amurland. 



15. Gemis : C^liloroiuacliia Warr. 



An Indo-Austrahan genus of only two or three species, luitil recently entirely unknown from the Pa- 

 learctic Region. The species which Wilbman has just described from Japan is, however, quite closely related 

 to the widely-distributed divapala, fully agreeing in structure. The genus is characterized by long third joint 

 of palpus in the $, ciliate antenna of both sexes, densely hairy pectus, short cells (especially of hindwing) and 

 stalking of first median of hindwing. From Ochrognesia, which it somewhat resembles in facies, it may be readily 

 distinguished by the non-pectinate antenna of the ^ and the long palpus of the $. 



infracia. C. infracta Wilem. Bright green, costa of foreA\ang fleshy ochreous speckled with brown. Forewing 



with the lines fine, white, indistinct anteriorly, a moderate-sized white spot at middle of distal margin. Hind- 

 wing with postmedian white line strongly outcurved between third radial and second median, the area distally 

 to it mostly occupied with flesh-coloured blotching, speckled with brown in places. Under surface whitish, 

 forewing green in costal half and with a rather large dark cellspot, hindwing with a dark apical blotch. Re- 

 calls the female of divapala, but has only a very minute instead of a large blotch at anal angle of forewing ; 

 moreover divapala-'^ lacks the white marginal spot. Of the new species only the ^ is known. Collected in August 

 1900 and 1901 near Kobe and at other localities in the island of Hondo by Wilbman. 



16. Genus: Ovlii'og'iiesia Warr. 



Palpus with second joint rather long, rough-haired above and beneath, third joint small. Antenna in 

 (J shortly pectinate. Legs short, hindtibia in ^ dilated, with hair-pencil and terminal process. Abdomen not 

 crested. Forewing with first siibcostal free. Hindwing elbowed at end of third radial, cell short, second subcostal
