PTYCHOPODA. By L. B. Proot. 93 



ground amid a growth of aromatic woody flowers, in company with macilentaria, litigiosaria and swarms of 

 sericeata. In Sicily Staudinger captured determinata at light in September — October. In one or two of the 

 Sainte-Baume examples the median line is so weak as to suggest a transition towards mutilata Stgr., which 

 however I am not able to compare. 



Pt. fasciata Stgr. Unknown to me. Said to be nearest to determinata Stgr., though with a super- iasoiata. 

 ficial resemblance to diffluata H.-Sch., which is structurally quite distinct. Size of determinata. Bone-colour, 

 with black discal dots, closely followed by a moderately broad, sharply defined grey-black band which is irre- 

 gularly dentate distally; foremng in addition with a sharp blackish inner line. The area between the band 

 and the distal margin is largely occupied by two faint dark shades (narrow bands) which enclose the pale 

 subterminal line. Fringes with black dots at base. On the under surface the inner line is wanting; the dark 

 band, especially on the hindwing, is more broken up into the two lines (median and postmedian) from whose union 

 it was composed. Even on the upper surface the band (which is about 2 mm in breadth) contains remnants 

 of the light ground-colour, especially in one aberration on the hindwing. Only known from the eastern Tau- 

 rus, where it was discovered in June. The possibility does not seem to me to be excluded that it may be 

 an aberration of determinata, bearing to it the same relation as aversata L. to ab. remutata L. 



Pt. litigiosaria Bdv. (= morosaria H.-Sch., agraria Joan.) (4 b). Characterized by the entire ab- litigiosaria. 

 sence of the median line, the forewing therefore having only two lines, the hindwing only one; the dark 

 shading to the pale subterminal is weak. Discal dots black, distinct, variable in size; distinct black dots 

 on the base of the fringe are often present, sometimes large, but are very inconstant. The under surface of the 

 forewing is more or less strongly infuscated, leaving a pale line distally to the postmedian and a pale sub- 

 terminal; that of the hindwing is pale and very weakly marked. Very variable in size and in the strength 

 of the markings, even also in the degree of sinuosity of the postmedian line; sometimes the inner line of the 

 forewing is wanting. My only Algerian example is rather weakly marked and differs from my Spanish series 

 in having the forewing scarcely at all infuscated beneath; but I do not think the name agraria (also founded 

 on an Algerian example) can be maintained as representing a distinct race. — ab. dissidiata Guen. has both dissidiata. 

 lines very distinct, blackish, the postmedian more strongly sinuous than in the type form, very pronouncedly 

 incurved between the radials. The two specimens on which Guenee founded the name, one from Andalusia 

 and one from the Basses-Alpes, were a little larger than normal litigiosaria, their ground-colour more unico- 

 lorous, the discal dot of the hindwing almost smaller than that of the forewing, whereas in typical litigiosaria 

 the reverse is more usually the case; and he regarded his dissidiata as "well distinct" specifically. Staudinger, 

 however, on examination of the types, informs us that it is certainly a mere aberration, an opinion in which 

 I heartily concur. Egg nearer spherical than ovate, its lower pole narrowed; surface very finely granulated, 

 with small, slight, polygonal depressions. Larva similar in form to that of aversata, gradually tapering an- 

 teriorly from the fifth abdominal, strongly carinated laterally, folded transversely, rugose, especially anteriorly 

 and posteriorly; yellowish grey, paler laterally, much darker ventrally; a double dorsal brown line, 

 usually interrupted, a subdorsal band also interrupted; variable. Pupa pale yellowish brown, anally 

 blackish, the bristles rather long; spiracles large and prominent. The moth flies in June and July and is attrac- 

 ted by light and by^artificial sweets. S. France, Spain, Italy, Corsica and N. Africa. 



Pt. mutilata Stgr. Unknown to me. From the description I should have supposed that it was another mutilata. 

 form of litigiosaria, even more extreme than ab. dissidiata, or possibly an aberration of determinata (which 

 was taken at the same time and place) with the median line wanting. Agrees with litigiosaria in structure, 

 in size and in the under surface. Light grey with very slight yellowish tinge, especially in the $. Discal dots 

 above at least as strong as in litigiosaria, beneath much weaker. First line distinctly present. Postmedian very 

 strong, on both wings strongly and irregularly dentate. Black terminal dots or streaks strongly expressed. 

 Sicily, taken at light in October. 



Pt. concordaria Piing., sp. nov. (= savdoniata, Homberg) {Si). For this new species, as well as Pt. rhodogram- concordaria. 

 maria, ostrinaria ab. oenoparia, hispunaria and degeneraria ab. floridaria, manuscript descriptions have been furnis- 

 hed by Herr Pungele r, in whose collection are the t3^es. He is therefore to be quoted as the author. I take this 

 opportunity to express my warmest thanks to Herr PIjngele r for the extremely valuable aid which he has rendered 

 in connection with this work. A large number of our figured specimens of the rarer species were lent by him 

 for this purpose, and he has further most kindly lent me for study whatever material I required from his 

 very rich collection, besides giving me much information and some critical expressions of opinion on difficult 

 questions. "Expanse 23 mm. Near the somewhat larger litigiosaria Bdv., more pointed-winged, more smoothly 

 scaled, colour more grey-yellowish, discal dots finer, median shade present, postmedian line less sharply
