,, ^^ ACIDALIA. By L. B. Pkout. 59 



Outer line nearly as in the preceding species, not (as is usually but not invariably the case in that) incurved 

 between the radials; the succeeding dark band rather irregular, often almost interrupted between the radials, 

 sometimes obsolescent throughout. The under surface is weakly marked, the forewing, or at least its basal 

 part, generally somewhat infuscated. Tientsin, June and again in August-September. I see no indication 

 at all of seasonal variation. The ^ hindtibia possesses the usual rather strong hair-pencil; the tarsus is two- 

 thirds as long as the tibia, thus much less abbreviated than in corrivalaria, with which species I origmally 

 compared it. By the leg structure, rounded hindwing, etc., the present is its more correct position. 



A. ochroleucata H.-Sch. ( ? = colonaria H.-Sch.) (5g) is a very inconspicuous species, and as it is also ochroieu- 

 tolerably variable and closely resembles some others, its determination is occasionally a matter of some diffi- '''''''■ 

 culty and uncertainty. Indeed it is not yet positively known whether it may not be the same species as mino- 

 rata Bdv. from South and East Africa or remotata Guen., which again may be a sjmonym of minorata. In 

 any case the species which we figure and which, though formerly considered rare, has now found its way into 

 most of the larger collections, is certainly the true ochroleucata H.-Sch. Pale straw-colour, finely and rather 

 sparsely dusted with fuscous, the dusting sometimes (as He rrich-Schaffe r gives it) more copious on the fringes. 

 The lines are lighter fuscous, varying in distinctness, the first on the forewing usually rather weak, more or 

 less obsolescent costally ; when distinctly enough expressed this line is seen to be rectangularly bent in the 

 cell. The median line is not as a rule thickened; it runs on the forewing nearly parallel with the distal 

 margin, or more commonly is incurved somewhat in its posterior half, on the hindwing passing just proximally 

 to the cell-spot, usually making a curve round it. The postmedian line is dentate and is somewhat incurved 

 between the radials and in the submedian area. The pale subterminal line is usually indistinct, being margined 

 by very little dark shading. Cell-spots black, that of the hindwing generally somewhat the larger. Underside 

 more whitish, especially the hindwing and posterior part of forewing; cell-spots and postmedian line usually 

 distinct, the other markings weak or wanting. Differs from both the preceding species in the strongly dentate 

 postmedian line, and usually in its somewhat smaller size and the absence of a noticeable dark shade or band 

 distally to this; from turhidaria and (though much more slightly) from manifesta, it also differs in the structure 

 of the (J hindleg, the tarsus being about three-fifths as long as the tibia. The antenna in the ^ bears rather 

 long fascicles of cilia; He rrich-Schaffe r describes than as "very long" in erecting his colonaria, which is pro- 

 bably a synonym, or more greyish aberration, of this species. His otherwise rather superficial description com- 

 pares it with humiliata Hufn. and straminata Tr., which both belong to Ptychopoda. ochroleucata inhabits 

 Southern Europe from Spain to Crete, also Cyprus and Egypt. I have seen it from several localities not enu- 

 merateel by Statjdinger (Calabria, Capri, Corfu, Crete) and suspect it is a good deal overlooked. — corcularia Ebl. corcularia. 

 from the Canaries is only a slightly smaller and darker form of ochroleucata and is treated by Staudinger 

 as quite synonymous with the type. This may probably prove to be correct, as Bohatsch has recorded the 

 same form as occurring among the type not uncommonly in Murcia. I have seen insufficient material to 

 justify a definite opinion, ochroleucata seems to be double-brooded if not triple-brooded; it appears in April- 

 May, July-August and even in Ssptember and October. The variation in size and markings does not seem to be 

 seasonal or sexual. 



A. inustata H.-Sch. is unknown to me. Its author hesitated as to whether it might not prove to be itmstaia. 

 a form of ochroleucata. Bohatsch regarded it as such. Staudinger, however, says that it is certainly not a 

 variety of ochroleucata. It was founded on a single $ in bad condition, of a reddish straw-colour, somewhat 

 narrower-winged than the preceding species, the dark dusting denser, particularly in the apical part of the 

 costal margin of the forewing and on the fringes. Bohatsch asserts that the blackened apex is not natural, 

 but due to the action of mercury, which was formerly used as a preservative against insects and other pests. 

 Recorded from Central Italy. He rrich-Schaffe r adds that "Herr Mann took the species at Baden near 

 Vienna", but this is probably an error. 



A. remotata Guen. I have not been able to identify this species certainly from Guenee's description, remotata. 

 but recent investigations have led me to doubt whether the species which we have figured under this name 

 (4e, probably a form of ignobilis) can be the true remotata. Orerthur identifies Guenee's type (supposed to 

 come from N. India) with"an Algerian form which I have unfortunately not seen, and at the same time with 

 a Natal species, which would undoubtedly be the widely-distributed African minorata Bdv. As Staudinger 

 regards remotata as probably a Darwinian form of ochroleucata, andOsERTHUR mentions no difference except 

 that the common transverse line beneath (postmedian) runs more parallel to the distal margin, the identifi- 

 cation with minorata seems probable enough, for the latter is so close to ochroleucata that I have hitherto 

 discovered no constant distinction, though its colour seems less yellowish. It is strange, however, that I have 

 not seen this species from India. Hampson and Leech confused various forms and allies, chiefly larger, under 

 the name of n^motata,. Itg nearest Indiar; representative, go far as I know, is really actuaria Walfc., recently
