the genus Eprrrh'oe. So, too, luctuata Schiff. must go to Euphyia, of 
which more anon. 
The “ hastata group,” in the narrowest sense, embraces only a 
single species and its varieties, races and Darwinian forms or species, 
if we may include among the last-named the Japanese hecate Butl., 
which seems a little less close to hastata than the others of the group, 
and proserpina Alph. (Rom,. Mem., ix.. p. 183, pi. x., fig. 5), of which I 
know next to nothing—only that figure and description point to a 
near relative of hecate. But there are a few other species (Japanese 
or Chinese) so near to hastata in structure that Mr. Warren (in lift.) 
advocates placing them in the same genus, and I am strongly inclined 
to believe they are veritable “ mimics ” of the distasteful Abraxinae. 
Before passing on, I should like to enlarge a little on this last 
point. It seems pretty clear that our European hastata has made 
absolutely no attempt in the direction of mimicking, say, Spilote yrossu- 
lariata (or even Lomaspilis marrjinata, if we may assume that 
comparatively retiring little species to be of the “warning” type, 
which I much question) ; but that it (hastata) has evolved its spotted 
pattern and sharp contrasts to suit its day-flying habits. But when 
we trace the modifications of its eastern relatives, step by step, we 
cannot fail to be struck with the increasingly Abraxine appearance of 
many of them. In luqens Oberth., which I have already mentioned, 
the body has become yellow, while the wings are still near semenovi 
and other tolerably normal “ carpets.” But in placida Butl. and its 
allies (or varieties) evanescens Butl., and propinqua Butl., the yellow is 
appearing on the wings also, and the same is the case with the similar 
and not distantly-related whitelyi Butl., for which Warren (Nov. Zool., 
x., p. 264) has erected the genus Calleulype ; while in some further 
undoubted Larentiids, such as latifasciaria Leech (the type of 
Xenospora Warr., Nov. Zool., x., p. 265), interrupt aria Leech (? genus), 
etc., the abraxine appearance seems to me still stronger; and it 
culminates in such species as Callabraxas triyoniplaya Hmpsn., Christo- 
pliiella aynes Butl. (== festinaria Stgr.) and “Gandaritis” maculata 
Swinh. It may be added that Xanthorhoe (?) abraxaria Butl. has also 
an Abraxine-looking body. It appears that Spilote sylvata (ulmata) is 
an extremely abundant Asiatic species, with varieties or subspecies 
innumerable, and it would not be surprising if it and some of the 
other abundant Eastern Abraxinae (Percnia, etc.), attracted some 
true Batesian mimics, although in my ignorance of field work in these 
lands, my suggestion must be taken as purely speculative. 
Mr. Warren would constitute our genus as follows : —hastata Linn., 
subhastata Nolck. (var. or subsp.), thulearia H.-S. (sp. Darw.), hecate 
Butl., proserpina Alph., lugens Oberth., kezonmetaria Oberth. (?), 
placida Butl., evanescens Butl., propinqua Butl., and perhaps a few with 
which I am not acquainted; he also adds a strange South American 
species (from Ptreopolis) which he has named nondescri/ita (Nov. Zool., 
viii., p. 465), and which does not seem to fit anywhere else; but one 
would here suspect accidental convergence, as the group is otherwise 
exclusively holarctic and oriental, and I am not sure whether it even 
extends very far south in China. 
The genus forms a section, but in any case not the typical section 
of Meyrick’s somewhat mixed genus Plemyria (accepted by Hulst, 
Trans. Amer. Pint. Soc., xxvii., p. 279). The type of Plemyria, and so
