spot. Somewhat nearer in colour to abbreviatei than to cocciferata. According to Mabille the commoner form 
on Corsica; in the Department of Aude both forms about equally numerous. Transitions occur. 
E. insignifica Rothsch. “Uniform dark sooty grey with a very large number of paler crenulated trans- insignifica. 
verse hair-lines. Length of forewing 13 mm.” A £ (not “d 1 ”, as published) from Guelt-es-Stel, 4 November, 
unfortunately rubbed. It looks similar to a dark coccijerata with the markings of the forewing more evenly 
expressed throughout, but the frons, wing-shape and palpus seem to associate it with a still more worn from 
the same locality dated 15 October. The latter, which has a wing-length of 11 mm and may well be a smaller, 
more dusky form of arenitincta, differs from coccijerata as follows: face more protuberant; palpus 1% or scarcely 
(in coccijerata at least 1%); abdomen somewhat less robust, body-plate scarcely so strong, its distal margin 
less indented in the middle, laterally produced into pointed teeth, recalling that of pini; forewing slightly more 
elongate, hindwing with less suggestion of the sinuosity which in coccijerata is almost as pronounced as in ab- 
breviata. 
E. arenitincta sp. n. (181). Length of forewing in both sexes about 13 mm. Ciliation of antenna, as in arenitincta. 
the two preceding, about 1. The confusion which already hangs over insignifica prevents my describing as a 
form of the latter, but the structural differentiation from the former is applicable. Very distinct in aspect, 
much lighter and with a sandy tinge, generally inclining to pinkish buff; dark dashes on the veins obsolete or 
short and inconspicuous. Algeria, February—April: Colomb Bechar, the type series; Bou Saada; El Kantara. 
All in the Tring Museum. 
E. tenerifensis Rbl. (Vol. 4, p. 295). A single worn specimen was determined by Bohatsch as long lenerifensis. 
ago as 1893 (Iris, Vol. 6) as variostrigata Alph. and this determination was accepted until better specimens were 
obtained many years later. 
E. massiliata Mill. (Vol. 4, pi. 13 i). Although the range was given comprehensively in Vol. 4 (p. 295) massiliata. 
as Mediterranean, I do not think it had been found in Morocco until Le Cere and Talbot took it in the Great 
Atlas in 1927. Subsequently Reisser has added the Riff Mountains. — peyerimhoffata Mill., bred from larvae peyerimhof- 
from “Spain” which fed on the flowers of evergreen oak, was said to be less round-winged than typical mas- t«ta. 
siliata but not so acute-winged as ultimaria, to which it was likened in markings. Dietze says that large 
specimens from Catalonia have been distributed under this name. 
E. gomerensis Rbl. (= boryata A Rbl. olim, err. det.). The receipt of a pair of true boryata Rbl. (see gomerensis. 
below) from K. Schumacher in 1913 convinced Rebel that he had mixed two species and he restricted the 
earlier name to the $. gomerensis is at once distinguishable by the much longer ciliation of the A antenna and 
the pronounced brownish coloration (in boryata clear grey); postmedian of forewing distally light-edged, cell- 
streak much thicker, abdomen with much shorter anal tuft. Orotava, Tenerife. 
E. boryata Rbl. (Vol. 4, p. 295). Rebel has revised this species in the light of the discovery of the boryata. 
preceding. Antennal ciliation of the <$ only short; a long white-grey anal tuft. Cell-mark of forewing long, 
oblique. The narrow wings and their light-grey colour easily distinguish it from massiliata; $ ciliation similar, 
shaft more slender. Type $ from St. Cruz. As we have not been able to obtain coloured figures of this and 
gomerensis, I would refer the reader to Dietze’s fig. 885 and 884 of the respective types. 
E. ultimaria Bsd. (Vol. 4, pi. 12 k). The distribution of the name-typical race should have been given ultimaria. 
as S. Eurojie and Egypt, though perhaps the Egyptian will have to be transferred to Turati’s inversaria, if 
tenable. According to Amsel, 2 $$ from Ain Karim (about 10 km W. of Jerusalem) form a transition between 
the f. minuscidata Alph. and opistographata Dietze and he inclines to refer his Biskra specimens to the same; 
but one taken at Jericho must, he says be referred to (ab.) dilucida Dietze. It appears that the forms are, for 
the more part, aberrations rather than subspecies, or that, the right differential characters have not yet been 
made out; Dietze determines a Gafsa (Tunis) specimen as typical minuscidata and an Egyptian one as ab. 
dilucida. — ab. dilucida Dietze. Smaller, much paler both above and beneath. Type from Haifa. — tornifascia dilucida. 
Rothsch., a J from midway between Ouargla and El Golea, unfortunately not in very frish condition, seems tornifascia. 
to be a narrow-winged, rather pale ultimaria (ab.?) with the cell-dots somewhat reduced and the anterior part 
of the hindwing whitened. More material from the district would be welcome. — arenicola Rothsch. is very arenicola. 
pale above (whitish with a sandy tinge), rather sharply banded beneath though not like opistographata . Oued 
Mya, Central Sahara, 2 only known. — inversaria Trti. (17 i). The types of this and several others of his re- inversaria. 
cently described Eupithecia have been very kindly lent by Count Turati for study in connection with this work. 
inversaria appears to be a dwarf form (length of a forewing 6 mm), not very sharply marked above and with 
the postmedian somew r hat less angled near the costa than usual, the underside showing a decided approach 
to that of opistographata. Cyrenaica. — opistographata Dietze is widely distributed in Asia, though not ahvays opislogra- 
equally extreme. My brief diagnosis (Vol. 4, p. 295) did not adequately express the striking character of the phata.
