HAPLOTHYATIRA; MELANOCRASPES; GAURENA. By Dr. A. Seitz. 189 
should however be remarked here that specimens also occur in the indian and formosan decorata Mr., in 
which the rosy spots on costa more or less conjoin, as is shown by the specimen illustrated in Vol. 10, 
pi 85 a In the illustration given by Houlbert, all the spots are separated .— Matsumura creates a separate 
Genus, Hamya, for Th. violacea Fixs. (Vol. 2, p. 324, pi. 49 e), whilst Houlbert designates same as a quite 
typical Thyatira. 
Genus: Haplotliyatira Houlb. 
This Genus based on 2 species and created in 1912, is said not to differ structurally from Thyatira, 
but only in the markings and colouration. The species have less than 5 eyespots on forewings. I hey aie 
rather large in size and their general appearance approaches that of the Cymatophora. 
H. transitans Houlb. (11 d). Of the eyespots of batis one can only discern indications in the form of iransitans. 
slightly paler, rosy tinged patches. There is a small spot of such a nature of irregular form, rather vio¬ 
let grey at base of forewings; a second one in centre of costa and a further smaller and whiter one just 
before "the apex. Hindwings reddish grey-brown. From Tze-ku i. e. from the boundary of palaearctic terri¬ 
tory. It is fairly close to the indian Th. labiata Gd. (Vol. 10, pi. 85 b). 
H. unipundata Houlb. (15 e). Size, shape and colouration of hindwings as in transitans-, on fore- unipuncta- 
wings however the rosy eyespots are completely absent except for a faint patch before apex; forewmgs aie 
traversed by undulate, angulated transverse bands, such as occur in Cymatophora. From Sikkim, we are 
enumerating this species here as it is not mentioned in the Indian part of the work and as it is a boundary 
species of .quite eastern palaearctic character and despite the fact that it has not yet actually ieen c is- 
covered on palaearctic territory. 
Genus: Ilelanocraspes Houlb. 
Houlbert places in this Genus, which he created for a group hitherto placed in the thyatira s f ecl * s 
having a subterminal band on hindwings; he includes 8 species which are distributed on about the 30 latitude 
from Thibet to Japan. 
M. (Th.) stramineata Warr. (Vol. 2, p. 324, pi. 55 n). It should be mentioned here that the denomina¬ 
tion on pi. 55 n of Vol. 2 was erroneously given as “straminea” instead of stramineata. 
M. (Th.) conspicua Leech (Vol. 2, p. 324, pi. 56 e). This species also occurs in Thibet and Mandchuna. 
M. fasciata Houlb. from Thibet and West China (Ta-tsien-lu) is as large as stramineata Warr. and conspi- fasciata. 
cua Leech (vide Vol. 2, p. 324) which it also resembles, but the forewings are duskier, the pale eyespots ess 
prominent. On hindwings the black outer band is nearer the base and narrower than m conspicua. mg 
expanse 55 mm. 
M. simplificata Houlb. (lie). Forewings without eyespots, deeper grey, paler slate-grey with chalky «™'V l 'Vr^ 
white in basal area and beyond the centre, the discal area dark brown-grey, traversed by blackish dentate 
lines, outer area cloudy violet-grey, fringes paler and spotted with darker grey. Hindwings with dull brown 
outer band intersected by the pale veins. The band is about 2 mm from margin. From one ? from Fast 
Thibet, illustrated from a figure of Culot in Oberthur’s “Etudes Lepid. compar. . 
Besides the above species Houlbert classifies here still flavida Btlr., oblonga Pouj., flavimaigo Leech 
and pryeri Btlr., all of which are illustrated in Vol. 2, pi. 56 e and i. 
5. Genus: Oaiirena Wh-. 
In regard to this Genus in which today a dozen species are classified, compare Vol 2 p. 326 and 
Vol. 10 p. 659. — Houlbert subdivides the Genus into various Subgenera (Chlorogaurena with florens Wh)., 
sinuata Warr., olivacea Houlb.; Griseogaurena with grisescens Oberth., argentisparsa Hmps. and Cyclogauiena 
with florescens Wkr. and gemella Leech.) 
G. Olivacea Houlb. (14 b). This is placed next to florens Wkr. (Vol. 2, p. 326, pi. 49 e) but the ohmcea. 
yellowish spots on forewings are so enlarged that several of them become confluent. Ta-tsien-lu, West China. 
G. florescens Wkr. (Vol. 2, p. 326, pi. 55 n). Besides occurring in West China and Northern India, this 
species is also found in Thibet.
