SBRISTAN AND  BALUCHISTAN IN 
WINTER. 
By Major F. C. Fraser, 1.M.S. 
LIBELLULINAE. 
Genus Orthetrum. 
O. taeniolatum, Kirby. 
Two males taken at Saindak near the Persian frontier, W. 
Baluchistan, 17-11-18. ae [Dragon-flies I believe to have be. 
longed to this species were also seen near the Hamun-i-Helmand in 
December. JN. A.]. 
One specimen is normal, the other departs from the type by 
having only one row of cells between Rs and Rs in all wings. 
Both specimens are fully adult and pruinosed. 
In the collection are two specimens of Libelluline larvae, 
taken in the Residency garden, Quetta, 10-11-18. These belong to 
the genus Orthetrum and are probably taentolatum. They closely 
resemble larvae of the latter taken in the Deccan, where they 
are common in shallow streams, concealed beneath curtains of 
Spirogyra and other water-weeds. The eyes are prominent and 
strongly angulated outwards; the body is depressed and squat 
and the dorsal carina of each segment, except the roth, ends with 
a sharp, robust spine. The whole body is hairy, this coat serving 
to pick up debris and flocculent detritus during life, which serves 
both for concealment from its foes and as an ambush for its 
prey. 
[The larvae were taken among dense weeds in a pond fed by 
an underground source of water distinctly warmer than the air at 
the time. WN. A.]. 4 
AESCHNINAE. 
Genus Hemianax. 
Three Aeschnid larvae from Hanna Stream, ca. 6,000 ft., near 
: 8 
Quetta, Baluchistan, 10-11-18. 4;. None are fully grown so 
that it is impossible to tell to what the insects belong by a study of 
the tracheation, but I think that there is no doubt that these are 
the larvae of Hemianax ephippiger, Selys, a common insect around 
Quetta. [These larvae are from a small stream with a luxuriant 
growth of Characeae, amongst which they were concealed. JN. A.]
