HYPERTHYRIS; DYSODIA; GLANYGUS; HERDONIA; DIXOA. By Dr. A. Seitz. 



aperla. 



2. Genus : IIj'i>ertliyris Leech. 



Larger and more robust than the previous forms, the body stouter, the abdomen not narrowing ab- 

 ruptly at segment 5 and not so pointed. Head broad; palpi hairy, upturned, segment 3 naked and acute. 

 Tibiae with lon» hair. Wings entire, of ordinary contour, the cell closed in tiie forewing, open in hindwing; 

 the distal margin of the latter somewhat curved, with obtuse apex. Both wings hyaline on the disc. ■ — One 

 Asiatic species, which occurs in India and China, crossing the Palearctic boundary in the East. 



H. aperta Leech (50 e). Black, the collar edged with golden brown, the wings vitreous, with black border. 

 Forewing with a large, triangular, black patch in the middle of the costal margin. — Kiukiang in China. 

 Our figure is taken from the type in coll. Leech, London. 



3. Genus; I>y>so(tia Clem. 



This genus, better known under the later name of Varnia, comprises 7 species, of which 3 occur 

 in America, 3 in India and 1 in Africa. The species which crosses the Palearctic boiindary in Kashmir, is 

 very widely distributed and has been redescribed over and over again. The body of Dysodia is exceedingly 

 stout, and the very small head bears obliquely upcurved palpi of medium length. The cell is closed in boti' 

 wings ; the apex slightly produced, the outer margin feebly ventricose at the tips of the median veins ; the hind- 

 .ving bears a discal spot which is nearly or entirely without scaling. — The moths have a clumsy flight, 

 and fly by day in the sunshine clearings on in woods, but also come to the lamp at night. 



D. ignita Walk. (= inaequalis Walk., rajah Bdv., siculoides Feld., fenestrata Moore) (50 e). The body 

 clothed with \evy smoth and glossy scaling, the thorax as well as the abdomen, purplish brown like the wings; 

 the latter minutely pencilled, the marginal area paler; in the disc of the hindwing a cordiform median spot, 

 which is thinly scaled or entirely hyaline; as the spot is alwaj's vitreous in strongly worn specimens, it appears 

 probable that it is scaled in freshly emerged individuals and that the scaling disappears when the specimen 

 ypsilokles. takes to the wing. Widely distributed in India, where also occurs the form ypsiloides Pagenst., characterised 

 by the paler ochreous colouring, feebler markings and the Y-shaped vitreous spot on the forewing. — The moths 

 are not rare in grassy places; their flight is very awkward, so that a specimen on the wing has, in consequence 

 of its unusually heavy body, almost the appearance of a beetle or a tree-bug.

4. Genus: Cwlanyciis Walk. 



Allied to the preceding genus in the stout build and the vitreous spot on the hindwing, but differs in 

 the cell of the hindwing being open and the forewing having the apex broadly rounded and the distal margin 

 not incurved below the apex, but on the contrary excurved. — Only 3 species in Asia, two of ■i\hich, G. in- 

 solitus Walk, and tricolor Moore, occur in India, while the third is found in the East of the Palearctic Region. 



G. blachieriOfter/^. (50 e), from Siao-lu, is only known to me from Oberthur's figure, of which we bring 

 a copy. Oberthur, who does not mention anything else about the nature of the insect, desires to make 

 the genus containing this species the tjrpe of a separate family, which he calls ''Glonycinae" . However, he 

 abstains from any description or characterisation of this family. As the Thyrididae are a somewhat hetero- 

 geneous family, about whose affinities opinions are very much divided, the proposition may be worth consi- 

 dering. 



osacesalis. 



5. Genus: Heiuloiiia Walk. 



Two species form this genus, one being American and the other Asiatic. Bodj' stout, but not so thick 

 and short as in Dysodia. Palpi upturned, short. Forewing with the apex pointed and the distal margin 

 curved; hindwing with the outer margin evenly rounded. Cell closed in both wings, that of the hindwing 

 divided by cell- veins. — The facies of the moth recalls Geometers, while the long legs remind one of the Pyrals. 



H. osacesalis Walk. (50 e). One of the larger species of the family. Whereas the markings are irregular 

 on the forewing, the hindwing is crossed by two whitish mother-of-pearl bands, which are separated from one 

 another by a red-brown band divided by a thin pale line; the base of the wing also bears minute dots of mother- 

 of-pearl. — India and China, as far as Central and North China, but not reaching to Amurland, also absent 

 from Japan. 



6. Genus: m-Koa Hamps. 



Based on a species from North- West India which just touches our Region in Kashmir. Palpi very 

 minute, hairy, upturned; body smooth, stout, but the abdomen more pointed than in the preceding genera.
