SECOND YARKAND MISSION. 
Stenophylax micraulax, McLacklan, male.

Groove in costa of anterior wings, more enlarged. 
Apex of abdomen, from side. 
before its termination ; discoidal cell extending to near the base of the wing, its upper edge 
nearly straight, the lower slightly curved; all the apical cellules broad at the base, the 
2nd very broad, truncate, 4th also truncate, 3rd bi-angulate. Posterior wings pale greyish 
sub-hyaline, with sparse, minute blackish hairs on the membrane ; neuration pale ; discoidal 
cell rather shorter than in the anterior ; 1st apical cellule much narrower than the 2nd to 
4th, which are very broad ; upper branch of cubitus furcating about on a level with the 
middle of the discoidal cell. 
In the male the anal parts are arranged as follows The 8th dorsal segment is very large, 
testaceous, rather thickly clothed with long and 
strong testaceous hairs springing from small 
tubercles ; viewed from above its margin appears 
to be straight, with several strong testaceous 
spines in the middle placed closely together ; but 
viewed in front (or from beneath) the median 
portion is seen to be strongly turned under, 
forming a triangle, closely set with black tuber- 
cles. What appear to be superior appendages are 
band-shaped, flattened, slightly curved, truncate 
processes, little prominent, and inserted so far 
inf eriorly as to cause a doubt as to their true 
value. (It may be that they represent the inter- 
mediate appendages, and that the superior are 
only indicated by a tubercle projecting slightly beyond the margin above them). The 8th 
ventral segment is rounded on the margin, and from it proceed two short, broad, excessively 
hairy lobes, divided by a suture, and each excised on its margin, apparently belonging to the 
Dtli ventral segment ; internally each of these lobes is very concave, and lying in them 'are 
what appear to be the very short obtuse inferior appendages. What appear to be the penis- 
sheaths are sub-cylindrical processes, curved strongly inward in a forcipate manner and nearly 
touching at the tips, which are somewhat thickened, blackish, and furnished with short spines. 
The penis lies between them, and is strong and rather short. 
In the female the apex of the abdomen is very obtuse. The 8th dorsal segment broad (con- 
cealing the 9th in the dry insect), its margin slightly rolled inwards, and fringed with yellow 
hairs , the 7th ventral segment forms a kind of pouch, the 8th with a concave space, 9th in 
the form of a short open tube.

Pending the discovery of some method for satisfactorily dividing Stenophylax, this insect 
must be placed therein. It differs from any species known to me in the curious groove near 
the base of the costal margin in the anterior wings of the male, and also in the anal parts, 
which almost defy intelligible description. 
The external aspect is somewhat intermediate between the groups of which the European 
S. stellatus and S. concentricus are representatives. 
Platypuvlax, n. sp. 
Two females from the same locality as the last ; it is useless to describe them without 
more examples in better condition, and of the other sex.
