AGROTIS. By Dr. A. Corti and Dr. M. Draudt. 
C. tischendorffi Pglr. (11 a) resembles the preceding species in its shape, but is larger and distinguishable lisckcn- 
by the nice brick-reddish colour. Transverse lines distinct, blackish in dark brown in $. Hindwings with 
discoidal lunule and postmedian line, fringes reddish. Syria (Aleppo). 
C. libanotica Grti i. 1. (11a) is very similar to tischendorffi, but the wings are much narrower, mark- libanotica. 
ings much more diffuse and not blackish, but scarcely darker than the pale brick-red ground; fringes quite 
faintly checked. Hindwings paler without postmedian, only a faint discoidal lunule present; fringes perhaps a 
shade more reddish. Lebanon (Bcharre). 
C. optabilis Bsd. (Vol. 3, p. 249, pi. 50 m). A grey form that is rare in Algiers: — murina Culot oplabilis. 
occurring in September, October. On the othey hand more frequently — ochrea Culot with a more ochreous ^im-a’ 
to ochreous reddish ground colour. The type of optabilis originates from Montpellier, but also occurs in Algeria. 
Subgenus: Ogygia Him. 
Type: 0. signifera F . 
0. celsicola Bell. (Vol. 3, p. 35, yd. 7 g). The illustration is not bad, but rather too unicoloured brown, celsicola. 
a better illustration of the typical southern French form is given here (61). It is not easy to distinguish 
the species and forms of this group from one another. The west asiatic (Persian), specimens are alike with a 
form that has recently been described from Anatolia as — gracilis Wgnr. (6 1); these specimens are smaller and gracilis. 
more delicately built and have finer and denser markings. The ground colour is a monotonous pale chocolate- 
brown without the pale patches of celsicola. Hindwings are somewhat paler in the disc. — gueddelanea Oberth. guedde- 
(6 1) very probably belongs here, otherwise possibly also to forcipula. It is a larger dark brown form with lanea. 
more distinct postmedian line, which is absent in typical celsicola. From the neighbourhood of Lambessa 
(Djebel-Gueddelane) at an altitude of 1600—2000 nr.

the species. The <$ antennae are fairly crenate with faint wide notches, more shortly fasciculate than celsicola, 
which otherwise the species closely resembles. Besides the forms named in the Main Volume: bornicensis and 
nigrescens, there have recently been described: - lithargyrula Trti. (= samnitica Dhl.) (6k) a very pale, Uthar- 
bluish grey-white form from Sicily and the Abruzzi with generally clearly marked markings, which are rather gyrula. 
too heavy on our illustration. Also hindwings are paler than type. — helladica Rebel is another very pale helladica. 
but smaller and more clearly marked form than lithargyrula, from Greece. — hyrcana ? Corti i. 1. ? /. n. hyrcana. 
(61) from Askhabad is a dull grey, quite indistinctly marked wide-winged form in which only the sharp stig¬ 
mata with fine black circumscriptions and the basal streak are somewhat more distinctly prominent. — 
amasina Trti. (Stgr . i. 1.) (6 k) is on an average somewhat smaller, darker brown, almost coffee-brown, with amasina. 
slightly reddish hue; it originates from Amasia. - robustior Corti i. 1. (61). A large form which differs from robustior. 
nigrescens Hofm. by the paler hindwings in the the reniform stigma, which almost always, especially in 
the lower part, is filled with chalky white and the usually much darker and more diffuse markings of forewings. 
It occurs in May-June in northern Syria (Marash). The plate gives (6 k) an illustration of another specimen 
— obscurior Corti i. 1., about which I can only say that it is larger and darker than nigrescens; I am at obscwior. 
present unable to state anything in regard to where it occurs. 
0. libanicola Corti (7 a) is also closely related to celsicola, agreeing in regard to markings with same, libanicola. 
the colour, however, being rather more coppery reddish to brown; it is distinguishable by the much whiter 
hindwings with only narrowly brown outer margin and veins. The type emanates from the northern Lebanon; 
specimens from Marash (Taurus) are much less brightly marked and reddish; the latter occur in April, May, 
the Lebanon specimens only in June, so that possibly they are distinct races. 
0. latipeonis Pglr. (7 b) described as Euxoa, belongs according to Cobti with certainty in close prox- latipennis. 
imation to forcipula, which it closely resembles. Forewings very wide, earthy grey-brown with veins scarcely 
darker than ground, no transverse lines and rather indistinct whitish stigmata, having dark centre and circum¬ 
scriptions, the claviform stigma long and narrow. Hindwings white with dark marginal line, it also looks 
similar to the form improcera of A. signifera, but has more heavily ciliate antennae than same. Ili territory;

0. strenua Corti (7 c) is very close to the preceding species, but has more shortly ciliate antennae in strenua. 
the sex. Forewings glossy brownish grey, base and costal area paler, with short black basal streak to the 
double anterior transverse line, the stigmata also somewhat more whitish, reniform stigma large, the cell be¬ 
tween the two stigmata blackened; the posterior transverse line similarly distinctly double; in marginal area 
dark sagittate marks, subterminal line with whitish spots. Hindwings whitish grey, veins and margin dusky. 
From Transcaspia (Arwas). 
0. improba Stgr. (Vol. 3, p. 35, pi. 7 h) is another genuine species of this difficult group. The illustra- improba. 
tion in the Main Volume is quite good. It differs from related species by having no actual crater on frons, 
which however is roughened. The antennae of £ are neither dentate nor crenate, being merely finely fasci-
