HOLCOCERUS; HYPOPTA; PAROPTA. By M. Gaede. 
cheesmani. C. cheesmani Tams. Closely related to C. aries Pnglr. (Vol. 2, p. 420, pi. 53 b). Forewings white. A 
pale dull yellowish patch between the costa and upper wall of cell, similarly between end of cell and outer 
margin and again below cell to inner margin except in the region of the upper submedian nervure. In aries 
the yellow patches are less extensive than is shown in the illustration. The dark striations seem to be less pro¬ 
nounced in the marginal area of cheesmani. The pale hindwings on which there are only quite insignificant 
markings are very different. J 48 mm. Arabia. 
colossus. C. colossus Stgr. (Vol. 2, p. 420) (16 b). We are now giving an illustration of this species which was 
omitted in Vol. 2. 
3. Genus: Halcocerus Stgr. 
H. consobrinus Pnglr. (Vol. 2, p. 421, pi. 53 b). This species varies considerably in size (25—50 mm), 
also the form and distinctness of the submarginal line of forewings varies in each of the 8 specimens before 
shdjuzhltoi. me. The central band, when it is present at all, is very enwidened on costa. — sheljuzhkoi Schaiu. has a greyer 
ground colour. There is always a spot on vein 3 at outer margin, which only 2 of my consobrinus also show. 
! his spot conjoins with the submarginal line and median band. The main difference from consobrinus seems 
to be that the median band is scarcely enwidened at costa. The size also varies considerably: 35—55 mm ex¬ 
panse. Aksu. 
H. arenicola Stgr. (Vol. 2, p. 421, pi. 53 d) and insularis Stgr. (Vol. 2, p. 422, pi. 53 e). Whilst the form 
japonica. insular is from Askold is decidedly smaller than arenicola , japonica Gaede on the other hand is somewhat larger 
and the markings, which in insularis are already somewhat less monotonous, become still more contrasting 
tin ough the paler tiansveise stripes. Hindwings and abdomen are quite as brown as in insularis, forewings a 
puiei biown, not fuscous, the paler patches grey. Ihe inner half devoid of markings, a paler patch in median area 
insularis. from costa to inner margin. 44—50 mm. Yokohama. — We are giving a fresh illustration here of insularis (16 b). 
5. Genus: Hypopta Him. 
nycteris. H. nycteris John. Similar to thrips Hbn. (Vol. 2, p. 424, pi. 53 h) but the ground colour is a more ashy 
grey, the ocellus like mark is smaller and not circumscribed by a paler border. On the other hand a grey-brown 
shade extends from this spot to the apex. Antennae more boldly pectinated than in thrips. There are dark 
biown spots on costa and a similar coloured streak close below end of cell. Short dark striations in outer area. 
At margin there are minute triangular spots. Hindwings brownish grey. 36 mm. N. Ferghana. 
herzi. H. herzi Alph. (Vol. 2, p. 424) (16 b). The specimen illustrated as herzi in Vol. 2, pi. 52 h probably 
figuies a vaiiety of turcomanica (Vol. 2, pi. 53 h). We are therefore now giving an illustration of herzi from 
a cotype in the collection of Pungeler. It would almost seem as if herzi were only a pale form of turcomanica. 
intractatus Stgr. (Vol. 2, p. 424) would then also belong hereto, .it is not only faintly marked, but pale and the 
markings are quite diffuse. The specimen in the Pungeler collection is quite perfect and not worn. In the 
same collection there is one ^ from Kolp (Armenia, Korb) which has grey-white ground colour and not yellow¬ 
ish white. It has a few short rows of dots on costa near apex and besides a submarginal row. It has a great 
lesemblance to turcomanica, although it is classified under intractatus. herzi is usually yellowish white with 
daik olive biown stiiations and spots, of which a few are on the costa. A somewhat bolder row of dots extends 
from behind the cell to centre of inner margin. Another such row that proceeds from apex exactly joins with 
same. In turcomanica on the contrary the latter row extends outwardly of the row that terminates on inner 
mat gin, and diffuses. All the other differences in the ground colour and distinctness of other markings are 
not decisive, according to Apheraky. If this is so, also the 2nd specimen of herzi in the Pungeler collection 
would have to be classified with turcomanica. 
issycus. H. issycus B.-Haas (i. 1.?) (16 b). Somewhat similar to turcomanica Alph. Ground colour of the body 
is brownish white. Forewings white. The brownish black line from the apex extends downwards to vein 4. 
Somewhat inwardly of same a line then begins that ends slightly behind the centre of inner margin. Short 
black striations on costa. Basally of the two main lines there is a brownish shade. Similar patches in basal 
area and in centre of outer margin. There are small brown spots at outer margin, inwardly of same to the two 
main lines the colour is white. Fringes are marked with dark checks. Hindwings and abdomen faintly reddish 
brown. J 34 mm. Issyk-kul. 
mussolinii. H. mussolillii Trti. Very similar to the remarkably constant reibelli Oberth. (Vol. 2, p. 425, pi. 53 h). 
It is larger, ground colour somewhat darker. The silvery stripe on costa does not vary. The triangular central 
spot extends nearer to the outer margin. Also the lowest streak that projects threequarters to the anal angle, 
whilst in reibelli it only goes about as far as the middle of the inner margin. G 37 mm. Cyrenaica. 
6. Genus: I*aropta Stgr. 
pater. 
P. frater Warn. I his species was actually described as a Cossus, but as it is compared to lienleyi Rothsch. 
and niloticus Joan, we are placing same in this Genus. Warnecke deems henleyi and niloticus to Ire separate
