52. Genus : Stilbina Stgr. 
S. numida Obth. (Vol. 3, pi. 201, pi. 42 c) is not a Hypeuthina, but certainly a Stilbina. The ova are 
pale yellow, then salmon red. Larva is grey or reddish white, laterally paler reddish grey speckled with pale 
brown minute dots. The dorsal line is pale grey-brown, subdorsal whitish, interrupted below and with brown 
edge with wide dark brown undulate stigmatal having white upper and lower edges. Head yellowish with black- 
brown spot on either side. It feeds on various kinds of grass and resembles a Leucania larva, feeding only 
at night. It casts its skin 6 times and pupates in the earth in a cocoon. — I have before me a fine series of 
both sexes and it shows considerable variation. The ground colour varies from white to yellowish, pink and 
grey, markings are bold and rich or faint and sparse. To judge by these — mirabilis Trti. held by its author 
to be a genuine species, cannot be distinguished from many of these specimens of numida. The name may 
be used to designate the somewhat smaller, paler race with paler fore wings. Cyrenaica. As numida cannot 
be recognised from the illustrations in Main Volume, good illustrations of both sexes are now being given here 
(20 k). 
S. koreana sp. n. (20 k). As I have before me only 2 $$ with simple antennae, that have a badly rub¬ 
bed thorax, I cannot decide whether there w r as a tuft or not. I am meanwhile placing this interesting species 
to Stilbina. The double lobed process on frons is much bolder than in the two other species and is about as 
in Metalopha, but with only 2 projections instead of three. Otherwise all characteristics agree with Stilbina, 
veins 6, 7 of hindwings are short-stalked. Thorax and forewings are creamy yellow, orbicular and reniform 
stigmata have sharp black circumscriptions, the former is almost completely filled with black. Subbasal and 
the two central transverse lines partially visible by an appression of black scales, the posterior transverse line 
being the most complete. Subterminal line and other markings are completely absent. Hindvdngs glossy pale 
brownish grey, a slightly darker band-like patch before margin, fringes long and creamy white. Underside 
of forewings is grey-brown, that of hindwings creamy white. Described from 2 $2 from Corea (Silver moun¬ 
tains) in the possession of Dr. E. Wehrli, types in the collection of Dr. Draudt. 
53. Genus: Hypeuthina Led. 
H. fulgurita Led. (Vol. 3, p. 201, pi. 48 Id also occurs in the Taurus (Marash) according to a specimen 
captured in September and sent to me by Mr. Daniel for classification. Ova obtained by Dr. Bodenheimer 
in November, are at first reddish, then later bluish like poppy seed. The larvae hatch after 8 weeks and in the 
first stages are transparent grey-green with black dotted heads. When full grown they are sleek, very variable, 
ground colour brownish white with olive-yellow, iron-grey or black wide dorsal band. This is sometimes tra¬ 
versed by 4 fine whitish purled longitudinal lines enclosing darker rhomboid marks. Occasionally also there 
are x-shaped subdorsal markings, the space between same often having rufous spots. It is polyphagous on low 
growing plants and is hidden by day. The larva is full-fed in about 5 w r eeks and is fairly easy to breed up 
till the time of pupation, but then, like the more southerly Ocnogyna , it becomes very restless and after a 
long period of racing around, the majority perish. A few imagines emerged in March of the following year 
and there are probably 2 generations. We are illustrating one of the bred specimens (201). 
57. Genus: Delta Saalm. 
D. peterseni Christ. (Vol. 3, p. 203, pi. 42 c, d) is not a Zenobiinae but should have been classified as 
a genuine Hadeninae after Barathra brassicae (Suppl. Vol. p. 96) in the Genus Trichorhiza Hmps., that was 
especially created for it. The Genus differs from Barathra by a rounded process on frons that is excised below 
and by the absence of the curved spine or claw on foretibiae. 
58. Genus: Ijithomofa Hbn. 
L. rectilinea Esp. (Vol. 3, p. 203, pi. 42 d) — virgata Tutt (20 1) denotes specimens in which the dark 
brown median area of forewings extends uniformly np to the costa. — grisea Spul. are specimens of a greyer 
colouration, without brown. 
59. Genus: Pnlcheria Alph. 
P. cinescens sp. n. (20 1) is the same shape and has the same arrangement of markings as catomelas 
(Vol. 3, p. 203, pi. 42 d) of which we are giving a better illustration here (201). Forewings are completely 
dusted with bluish grey, so that the markings are obscured and only the stigmata and the commencements of 
double transverse lines on costa are slightly more apparent . There is a small oblique streak subapically between 
5 and 7. Hindwings grey-brown, paler at base, with faint brownish postmedian and whitish fringes. Syr- 
Darja (Baigacum). Type in the collection of Puncieler in the Berlin Museum.
