120 SIDERIDIS. By Dr. M. Dbatjdt. 
S. properssa Pglr. (Vol. 3, p. 98). We are able to give an illustration (15 h) of a specimen in the PtixGELER 
collection. 
S. andereggii Bsd. (Vol. 3, p. 98, pi. 25 b). — pseudocomma Rbl. & Z. (15 h) is larger than type; mediana 
and its branches are more widely outlined in pure white, also the whitish colouration at end of cell is whiter 
and the dark shading, that is there in andereggii, is absent. Marginal dots are small or absent. Many of the 
$$ are a darker brown, corresponding to the form cinis, but transverse lines are almost always absent. A sub¬ 
species described from Albania, which strongly resembles comma, but also reminds one of lineata Ev. from 
S. E. Russia. 
S. 'phlebitis Pglr. (Vol. 3, p. 98, pi. 24 b) and 
S. Jordana Bartel (Vol. 3, p. 98, pi. 24 c). Both these illustrations w-ere very poor copies from Hampson. 
We are l’eplacing them by better illustrations here (15 i). 
S. sicula Tr. (Vol. 3, p. 98, pi. 25 c). — cinnarnomea Trti. (15 i) is a small form from Sardinia that is 
suffused by cinnamon brown. - albivena Grasl. (= fuscilinea Grasl.). The main characteristic of this form is 
not the row of dots on veins, but a prominent blackish longitudinal streak under the delicately white mediana, 
which extends beyond the cell under vein 5. It certainly also occurs in central Italy and there is a typical 
specimen from Aix-la-Chapelle in the collection of Pungeler! — belgiensis Lamb, is an extreme form of the 
preceding with especially bold black longitudinal streak. From Belgium. 
S. alopecuri Bsd. (Vol. 3, p. 99, pi. 24 b). In place of the unrecognisable illustration in Main Volume, 
we are giving a fresh picture (15 i) of this insignificant species, from a specimen from Kertsh. 
S. putrida Stgr. (Vol. 3, p. 99, pi. 25 d) is a genuine species and has no connection with indistincta Chr. 
On the other hand — palaestinae Stgr. (Vol. 3, p. 99) has no claim to specific rank. It is only a larger form 
of the preceding, somewhat more reddish in tone, without the blackish longitudinal streak below the cell. Neither 
is the marginal area blackened. An illustration is given here (15 i). 
S. scirpi Dup. (Vol. 3, p. 99, pi. 25 e). — serratilinea Wgnr. has a sharply dentate postmedian trans¬ 
verse line. From Gravosa. — virata Costni. has monotonous dull yellow-grey forewings without the central 
longitudinal shade and transverse row of dots. Veins very prominently white. From Mte Gibbio, not rare 
in the Spring brood. — syriaca Osth. is larger than type and the form montium (29—33 mm) has forewings pale 
yellow-grey with faint reddish brown sheen, markings varying in intensity, the black dot in reniform stigma 
prominent. Hindwings grey-white, darker at margin. In 2 broods in the Taurus (Marash). 
S. opaca Stgr. (Vol. 3, p. 99, pi. 24 c) and 
S. mesotrosta Pglr. (Vol. 3, p. 99, pi. 24 c) were illustrated from bad copies and are therefore now- 
being illustrated afresh (15 k). 
S. favicolor Barr. (Vol. 3, p. 100, pi. 25 k) is found to belong also to the german fauna and especially 
that of Slesvig-Holstein, according to the discoveries of Heydemann, who has found the species on the islands 
of North Friesland. It occurs apparently mainly in the fuscous forms and is found at night on marram grass 
flowers. 
S. impura Hbn. (Vol. 3. p. 100, pi. 25 f). — dungana Alph. is now illustrated from a tvpical specimen 
(15i). 
S. pallens L. (Vol. 3, p. 101, pi. 25 g, h). — Candida Pocci is the pure white form without the slightest 
yellowish hue. From Piedmont. 
S. algirica Obth. (15 k) is best classified next to obsoleta (Vol. 3, p. 101) and straminea. Upperside pale 
grey, forewings with faint reddish suffusion, paler than the rather more blackish grey hindwings. Between 
the veins there are delicate black striations, behind the cell there are a faint row of black dots as in obsoleta. 
Underside is glossy and silky, pale grey, costa of forewing whitish, blackish suffusion in disc, with black costal 
spot as in straminea. Hindwings on underside peppered with grey with black dotted line on both wings, com¬ 
mencing at costal dot. It is darker than straminea, especially on hindwings. No cell spots on underside; congrua 
differs by the white mediana on upperside and silvery gloss of underside; obsoleta has less quadrate contour 
of forewings, rather heavier black dots -on upperside of forewings, whitish disc on hindwings, only blackish 
at margin and with cell spots on underside. From Batna, Aflou and Lambessa in Algeria. Obviously in 2 gen¬ 
erations in June and September. 
S. pudorina Schiff. (Vol. 3, p. 101, pi. 25 i). pinguis Dhl. is a form that closely resembles rufescens 
Tutt. It is strongly suffused with red, but is so densely peppered with dark grey-brown speckles, that the nice 
rich red colour is scarcely apparent. It is a very large race from the Etschtal (Terlan). 
S. incognita n. n. (= impuncta Stgr. nec Guen.) (15 k) is best classified near to phlebitis. It was omitted 
from Main Volume. I have had an opportunity of inspecting the type, of which an illustration is now given. 
Forewings pale reddish yellow-brown, somewhat paler at inner margin, with whitish costa and veins, the
