1928] The Jurassic Insects of Turkestan 127 
the Museum, is a keen entomologist, especially interested in 
Lepidoptera. The Galkino collections at Tashkent have mostly 
been collected, and partly studied, by Mrs. N. Y. Besobrasoff, 
of the Faculty of Physics and Mathematics, Central Asian State 
University. I am much indebted to her for courtesies in con- 
nection with my work. I made notes on seven of the most in- 
teresting fossils, but for the present describe only three. Some 
of the others, as for instance a cockroach with the head extended 
forward beyond the oval prothorax, not concealed as in modern 
forms, will probably be described from other specimens by Mar- 
tynov. A very large Palaeontinid, the anterior wings about 38 
mm. long, hind wings about 18, is extraordinarily like a cicada, 
but shows a straight ovipositor, about 5.5 mm. long, projecting 
from the apex of the abdomen. A dipterous insect is of ex- 
tremely modern aspect, with two large dark spots on the wings, 
much as in modern mycetophilidae. 
Hymenoptera. 
Martynov described from Galkino a very interesting Ten~ 
thredinoid related to the Xyelidae, which we have long regarded 
as a primitive group. It actually shows the lanceolate cell (re- 
ally two cells, of course) contracted below and with an oblique 
cross vein as in modern forms. The antiquity of this structure is 
astonishing. In the Museum at Tashkent I found a second 
species of the same genus, which I propose to call Anaxyela 
martynovi. It is 13 mm. long (excluding ovipositor); black, 
parallel-sided, stout; width of thorax about 3.3 mm. of abdo- 
men about 3.5 mm; head transverse, thorax oval, abdomen with 
the sutures rather boadly pallid; ovipositor straight, 4.5 mm. 
long, about 0.6 mm. broad, sharply pointed but not gradually 
tapering; wings ample, hyaline, with black veins (venation as 
shown in fig. 1), stigma small, lanceolate, defined by a slight in- 
fuscation above radius; anterior wing about 10.3 mm; radial 
cell 5 mm. black beyond this creamy white (exactly same on 
both sides, so evidently natural coloration); length of antennae 
about 3.5 mm., or perhaps more. Martynov’s A. gracilis has 
the head and body about 9.2 mm., but the ovipositor much 
longer in proportion, being half the length of head and body.
