and flat; the anterior border projects well forward between the 
palps and is furnished along its free border with minute teeth. 
The opposed borders of the palps are similarly armed and each 
is furnished with a strong movable hook and five long, stout 
setae, directed inward. In addition, each has a robust spine at 
its end and a smaller one between this and the movable hook. 
The caudal lamellae are more or less lanceolate and acuminated 
at the distal end. ‘The tracheal ramification is pigmented and the 
lateral borders of the lamellae spined, the spines being robust on 
a little less than the basal half, and rather minute for rather more 
than the distal half. At the junction of these two different kinds 
of spines can be seen, in some specimens at least, a very faint 
suggestion of a transverse line, the only sign of the nodate charac- 
ter of the lamellae. The ends of the tibiae are richly tufted with 
spinous hairs and spines. 
These larvae were taken along with the two Libelluline larvae 
mentioned above, in the Residency garden, Quetta. One imago 
was taken at Lab-i-Baring, Seistan, ‘‘ lying on the surface of the 
water in channel in reed-beds in the Hamun,” 10-12-18, and the 
other two at Kirtaka, W. Baluchistan, near Afghanistan frontier, 
‘““among coarse grass growing on sand round a small spring.” 
The females of Jschnura commonly lie up among coarse herbage, 
in the neighbourhood of water, whilst the males rarely stray far 
from the neighbourhood of water. 
INDETERMINATE LARVAE. 
The other larvae (from the rice-beds of the Hamun-i-Hel- 
mand near T,ab-1-Baring) com- 
bine some of the features of an 
Agrionine larva with those of a 
Lestine. The middle-lobe (fig. 2) 
is typically Agrionine ; there is 
no suggestion of a middle notch 
as seen in the other family but 
the palps are highly differen- 
tiated and the movable hook is 
of great length. 
There is a stout hook on both 
sides of the movable one and the 
space between the outer hook 
and this is deeply serrated. The 
border of the inner hook is 
lamellated, its edge being fur- 
nished with a row of closely-set, 
teeth-like processes, similar to F1G. 2.—Mask of indeterminate larva

lobe and outer border of the 
palp. The palps appear to be more or less cupped by the lamellated 
extension.
