STERRHA. By L. B. Prout.

A. Section Sterrha: $ hindtibia with terminal spurs present (very rarely 
one o n 1 y). 
S. aureolaria Schiff. (Vol. 4, pi. 4 a). The restriction of the range of this southern and eastern species aureolaria. 
in North Germany to a few scattered loca lities has recently given rise to some discussion regarding the probability of 
its being a “Xerothermrelict”. It is not possible here to go into the arguments, but they show the absolute 
necessity of collecting reliable records, of the occurrence of local species and of their entire ecology. — ab. 
latistrigata Vorbr. & Mull.-Rutz has the fine lines replaced by thick streaks, on the forewing 3, on the hind- latistrigata. 
wing 2. Zermatt. — ab. pseudolutearia Osthelder. Lines reddish instead of blackish, thus recalling luteolaria pseudolu- 
Const. Schleissheim, S. Bavaria. Also known from Kelheim. -— transsylvanaria Dannehl. On an average a little f ranS xyp 1 "' 
larger and deeper gold-yellow, the lines, including the terminal, extraordinary fine and slight, less dark than vanaria. 
in the type. Founded on 18 4 Kronstadt district. 
S. luteolaria Const. (Vol. 4, p. 90, pi. 4 a). According to Chretien, the larva described by Milliere, luteolaria. 
which has formed the basis of the descriptions in our text-books, bears no resemblance to those which he (Chre¬ 
tien) has bred ex ovo from both its original localities — Font Romeu (Pyrenees) and San Ildefonso ■—- and the 
eggs sent to Milliere must have belonged to a different species. The adult larva is elongate, arcuate, attenuat¬ 
ed anteriorly, thickest at segments 7, 8, 9 (presumably .the 4th, 5th and 6th abdominal), each of which equals 
in length the entire thorax; segmental incisions very pronounced, especially posteriorly; yellowish grey, more 
or less shagreened and with small bosses; dorsal line yellowish white, subdorsal broader, blackish-brown, a 
strigiform dark-brown spot above the yellowish-white spiracular line on each of the first 6 abdominals. 
S. ochrata Scop. (Vol. 4, pi. 4 a) ab. major Dufrane merely denotes an extra large d' (“28 mm”), from Evreux, major. 
France and need not have been separately named.—ab. flavescens Galvagni. Much more striking, so that even so flavescens. 
experienced an entomologist as Dr. Rebel has suggested that it may be a natural hybrid, a too frequent and 
rarely justifiable explanation of abnormal aberrations. Wing-shape and fringes speak for ochrata (attention is 
directed to the acute apex of the forewing, excision in margin of hind wing and presence of a distinct dividing- 
line in the fringes, particularly beneath), the size and colour, on the contrary, for rufaria ; cell-dot wanting on 
forewing, indicated on hindwing. Founded on a $ from Neusiedel (Burgenland); a similar, but more reddish 
$ from the Island of Lissa is also referred here, as it remains paler than normal rufaria. 
S. numidaria Luc. (Vol. 4, pi. 4 b). Variable in size and in the position of the median line. Examples are numidaria. 
not infrequent in which it is so close to the antemedian as almost to give rise to the “ab. anastomosaria ncm. 
coll.”; at the other extreme, it may be fully twice as far from the ante- as from the postmed.ian. 
S. rufaria Him. ab. purpurea Reisser. Densely dusted almost throughout with violet-red, the broad purpurea. 
clear yellow' fringes strongly contrasting. Oberweiden. — ab. rufobrunaria Horhammer is another strongly suf- rufobru- 
fused form (“dark reddish chocolate”), but retains a yellow area between the median and the antemedian, naria. 
on the hindwing reaching the base; postmedian blackish. Naumburg. 
S. delibata Prout ( = rufaria Hmpsn., nec Hbn.) (5 g). More glossy than rufaria , forewing slightly shor- delibata. 
ter, median line stronger and somewhat thickened, postmedian and subterminals weakened ; fringe with small 
dark dots; hindwing termen slightly more sinuous, cell-dot strong, somewhat more elongate. Underside sharply 
marked. Kashmir, where it doubtless represents rufaria, though I can scarcely consider it a race of the 
same. 
S. turatii Sohn- Rethel. Only known to me from the description and figure. Said to be very similar to turatii. 
consanguinaria (vol. 4, pi. 4 b), but still lighter, and still more glossy, the markings obsolescent, with the lines 
more yellowish, not brownish. When, however, its author adds that it is structurally distinct in that the 2nd 
subcostal and 1st radial of the hindwing are stalked (a character that applies to all Sterrha), we are inclined 
to suppose that he has misidentified consanguinaria and that turatii may be a form of Lederer's species. 
Described from the Abruzzi (Gran Sasso). 
S. consanguinaria Led. ab. consecrata Stgr., which has been hitherto treated as a separate species (see consecrata. 
Vol. 4, p. 94), is shown by Zerny to be merely an infrequent banded aberration of consanguinaria , analogous 
to several in Sterrha. Among a series of 140 collected in the Northern Lebanon about a dozen are consecrata. The 
genitalia show no difference. 
S. determinata Stgr. ( = geministrigata Fuchs) (Vol. 4, pi. 3 e). I have repeatedly attempted to recon- determi- 
cile this variable species with Herrich-Schaeffer's description of his enigmatical nitidulata, which, if be¬ 
longing here, would be the oldest name for it. It w r as described without locality, but later matched with a 
Sicilian $ so similar to litigiosaria $ that he felt uncertain whether it, rather than his morosaria , was the 
other sex thereof. The locality, and the fact that its forewing possessed a median line, would favour deter¬ 
minata; but that line was explicitly stated to run proximallyto the cell-dot on the forewing and the 
underside had a strong terminal line beneath. Moreover, the description of the antenna fits better to that of 
nata.
