CIDARTA. By L. B. Prout.

postmedian line. Possibly in the silaceata group, as the figure shows traces of the characteristic terminal mark. 
Areole double, discocellulars of hindwing oblique, genitalia simple. S. Saghalien, 2 in August. 
Subgenus Lyncometra Prout. 
(See Vol. 4, p. 215.) 
This differs from Lampropteryx in its stronger palpus, slightly less elongate wings and probably some 
other details, but the genitalia indicate a near relationship. 
C. ocellata L. (Vol. 4, pi. 8 g). Possibly a separate subgenus for this species is superfluous and it might ocellata. 
be accommodated in Lampropteryx, with which the genitalia show a good deal in common. — ab. coarctata coarctaia. 
Prout (= stenotaenia Hellweger). This form was redescribed by Hellweger from Brixen, doubtless before 
he had seen my account in Vol. 4 (p. 216). My original description was in The Entomologist, Vol. 37, p. 154 
(1904), from an English specimen. — ab. caeruleotaenia Dannehl, several examples among a small Siebenburg caeruleotac- 
series (Cibinsgebirge), is characterized by the exceptionally blue tone of the median band. — ab. robiginata ro i ) - llJ i lia i' ( l l u 
Dannehl. Distal area of forewing in almost its whole extent suffused with dull rust-brown, only remaining 
w'hitish at the apex; the brownish border of the hindwing very broad. Type from Terlan, another example 
from Upper Silesia.

C. rubiginata Schiff. (= bicolorata Hufn., nom. praecocc.) (Vol. 4, pi. 8 h, as bicolorata). It has been rubiginaia. 
overlooked that Httfnagel himself gave to two species the name Phalaena bicolorata, without even the excuse 
that he had any subgeneric or sectional epithet interposed. His first bicolorata must of course stand. — A rather 
full biological sketch has been given by Grabe, who notes a superficial resemblance in the form of the egg 
and the pupa to those of Ennomos. The moth is attracted by honey-dew on leaves. As regards the range, 
Staudinger is right in including Japan (see Vol. 4, p. 216); well bordered specimens, and even such with 
nearly complete central band do occur there among the more dahurica- like forms. I have not seen enough 
Japanese material to make any complete analysis and can only say that it is there very variable. — ab. bi- bipundata. 
punctata Hannemann (= diadelphata Stauder) has in the posterior part of the median area of the forewing 
two superposed spots, thus making a transition towards the forms completa Rbl. and plumbata Curt. Type C 
and $ from Hagen in Holstein; Stauder redescribed from Innsbruck. — ab. peralbata Stauder has the upperside peralbata. 
of the hindwing and sometimes even the underside clear white, or only the cell-dot conserved. — ab. rosarium rosarium. 
Stauder. Terminal dark shading of the hindwing wanting, as in most of the Tyrolese, S. Bavarian and other 
southern forms; but the subterminal greyish shading is here conserved as a chain of spots. This and the preced¬ 
ing were likewise founded on material from the Innsbruck district, where occur also various transitions. Ost- 
helder records a similar range of variation in S. Bavaria. — ab. completa Rbl. Osthelder advocates the completa. 
resuscitation of this name for the not altogether uncommon aberration in which the two posterior spots of 
ab. bipunctata are united into a single patch, so that the median band of the forewing is complete except for 
a slender interruption at the submedian fold. As Rebel did not note any other deviation from the type, called 
completa an “ab.” (not “var.” or subspecies) and only wrote “cfr. Barrett, Vol. 8, pi. 339, fg. 1 b”, without 
specifying that that individual — a plumbata from my collection — was his type, I accept this argument, 
although Rebel ought to have cited Barrett's figure 1 a rather than 1 b. This aberration occurs also in the 
subspecies dahurica.

A. C antenna ciliate. 
C. phaiosata Stgr. has to be removed; see Vol. 4, p. 420. 
C. undulata Warr. (lib). In some respects more reminiscent of a grey siterata, or even of a Hydrio- undulata. 
mena (in which group Warren published it) than of any other Thera, but the projecting, fascicle-bearing joints 
of the C antenna refer it here; palpus longish-moderate. Apparently not variable; the shape of the band and 
particularly the clean white-grey, faintly olive-tinged area between this and the basal patch make it easy to 
recognize. Founded on a short series from Thundiani, Punjab, August and September. 
C. variata Schiff. (Vol. 4, pi. 8 h). Although the slight differences in the genitalia and the early stages, variata. 
as between this species and obeliscata, are not yet acknowledged on all hands to be absolutely constant, the 
evidence is gaining ground that they are biologically quite distinct and should be so treated. Even stragulata 
Hbn. is now plausibly claimed as a good species; see below. The antennal joints of the perhaps project 
somewhat more strongly and bear longer cilia in variata than in obeliscata, but extensive micrometric ex¬ 
amination will be required in order to substantiate this idea. Larval distinctions are discussed below, under 
obeliscata. Cockayne has made successful experiments in hybridizing and published his results in detail in
