EUCHERA; DREPANA. By M. Gaede.

14. Family: Drepanidae. 
Whilst Warren classified the Drepanidae before the Sphingidae and Saturnidae in accordance with 
ancient custom, most of the newer catalogues, as also Hampson (1925) place them much lower in the genealogical 
tree. Hampson places them with the Callidulidae, to which they are presumably closely allied, immediately 
after the Thyrididae, which on their part follow the Pyralidae and these are Microlepidoptera. We are therefore 
placing them here after the Sphingidae in view of the opinion held by many people, that they are related to 
the Notodontidae and by this method they are brought closer together. 
In regard to the Callidulidae there is only to be mentioned in addition to what was written in the main 
Volume 2, that this family, that is so difficult to define, is now rather differently composed to what it was 20 
years ago. The form Schistomitra funeralis Btlr. from Japan, which in VoG 2, p. 208 was classified as a Calli¬ 
dulidae, is today placed close to Nossa ( Atossa ); this change, which we had already anticipated, as we had our 
doubts as to the original classification, will explain why we had placed the illustration (Vol. 2, pi. 48 g) next 
to the Genera Nossa and Psychostrophia. — There is no need to refer further to the family Callidulidae-, 
on the other hand a number of new forms have to be added to the Drepanidae. 
1. Genus: Euchera Hbn. 
\ 
E. nigralbata Warr. As the author himself indicates that specimens from Gensan (Corea) represent nigralbata. 
transitions to E. capitata Wkr., dealt with in Vol. 2, p. 196 and illustrated on pi. 23 f., the main locality for 
which is Hongkong, this does not appear to be a separate species, but only a distinctly marked form. In typical 
capitata the forewings closely resemble those of the specimen illustrated as substigmaria on pi. 23 f., whilst the 
hindwings generally show the outer dark band wider than the central one. nigralbata has forewings just like 
the illustration of capitata Wkr. on pi. 23 f, but the bands are somewhat darker and the dark marginal band 
is generally wider. The hindwings of nigralbata are said to have rather darker bands. To sum matters up: 
all capitata designated thus and from Japan (which includes the specimens in the Pungeler Collection) would 
be more correctly classified as nigralbata,. I have only a single $ from Gensan before me. In this the white 
bands each side of the dark central band on forewings are wider. The central band itself is narrower; the 
same applies to the hindwings. The only feature that would enable one to refer to it as a “transition to 
capitata ’ woidd be the paler colouration of the dark bands. I have numerous specimens of the genuine capitata 
from Canton before me. Prout ascertained in 1918 that substigmaria Hbn. was an older name for capitata 
Wkr., both being typical from South China. Consequently a name is necessary for the Indian form of substig- 
maria: superstigmaria Prout. The typical substigmaria ( capitata) from China, Formosa, Tonkin is similar to the superstig- 
form intermedia Prout from Thibet, but less dark gi’ey than the latter. The cell spot on hindwings is fainter ■ntermedia 
on upperside, the submarginal spots are generally more distinctly conjoined by grey shadings. 
9. Genus: Drepana Schrk. 
A. European species. 
D. falcataria L. (Vol. 2, p. 199, pi. 23 g). Very pale specimens with almost obsolete markings on 
hindwings and which occur everywhere are named pallida Stepli. - - The counterpart, the dark form, has three pallida. 
denominations: infernalis Hofjm. ( = curvatuloides Wgn., obscura Sul.). All the markings of both wings are infernalis.
