and showing well the fine close cross-veins so characteristic of 
the genus. The hind wing also shows the large ocelliform mark. 
The ocelli of the hind wings are curiously similar to those of the 
orthopterous genus Tanusia and Pterochroza, from Brazil. 
Orthoptera 
The interesting genus Absitus of Martynov consists of 
long-horned grasshoppers of considerable size, with transversely 
banded wings. The males are said to have a well- developed 
musical apparatus. The genus was founded on A. fasciatus 
Martynov but to my astonishment when I called on him, Marty- 
nov produced drawings of a whole series of species, all showing 
the same general type of marking, though with much diversity 
in details. 
However, still another species, not represented in his series, 
is preserved in the museum at Tashkent. I will call it Aboilus 
besobrasovce. Figure 2 shows the pattern of the broad tegmen, 
so far as preserved, and a detail of the venation, with the char- 
acteristic oblique cross-veins, in the region of the black cunei- 
form mark shown just above. The insect is about 52 mm. long, 
with heavily spotted or banded tegmen which probably had a 
length of about 70 mm., but the apical part is not visible. The 
outline is not well shown, and the figure does not pretend to 
any exactness on this point. The ovipositor, not previously 
known in the genus, is well preserved, directed obliquely down- 
ward, about 18 mm. long and 2.5 mm. wide in middle (lateral 
view), straight ensiform. Hind tibiae about 27 mm. long and 
1 . 5 wide in middle, posteriorly with only small spines. Wings 
(tegmine) pallid, with heavy black markings directed transverse- 
ly, the largest being long-triangular or wedge-shaped, about 8 
mm. long. Width of tegmen at fourth transverse band 22.5 
mm., at third band 19.5 mm., at second band 17, and at first 
band 14 mm. The first dark band is about 12 mm. from base 
the second about 9 mm. beyond it, the third about 5 mm. beyond 
that, the fourth about 5.5 mm. further, then the fifth and sixth 
after shorter intervals. These bands consist of series of broad 
spots or markings, either separated from one another, or united
