Hab. Darjiling District and Khasia Hills. I have not seen a specimen of 
this insect which must be very rare or local. Concerning it Dr. Laidlaw states 
that it is scarcely a true Aeschna giving as reasons the difference between the 
trigones in the fore and hindwings and also the few rows of cells (3 rows only) 
between Rs and Rspl (5th nervure and 5a). 
Aschna annulata, Fabr. Ent. Sys. supp. (1798). 
The type of this species has been lost and it is doubtful as to which species 
Fabricius referred. His description is meagre :—size median, head obscurely 
yellow, thorax brown and hairy, abdomen cylindrical, pale yellow with the 
margins of segments black. Legs yellow. 
, reticulation open. 
Hab. India. 
Aschna, sp. nov. B. M. No. 98/242, Sikkim, 2,000’, June 1895, coll. J. G. 
Pilcher. 
I have seen a single female of a species of Aeschna in the British Museum indi- 
cated from Sikkim which does not belong to any described species. The altitude 
given is obviously wrong. 
The following is a description of the insect but I regret that at the time of 
examining it I failed to note the character of the dentigerous plate. 
Female. Head—Face and labrum bright yellowish green variegated with lines 
ef bright ochreous ; labium yellow with a spot of greenish in the middle ; frons 
with a broad, black crest; occiput simple, brown bordered with dirty yellow. 
Thorax brown or it may have been dark green during life, marked with 3 fine, 
black lines on the humeral and lateral sutures, the middle line being incomplete 
in its upper half. The front of thorax marked with dark green antehumeral 
bands, 
Abdomen dark brown marked with blue, this latter has a large apical, dorsal 
spot on each segment from 3 to 7 on each side of the dorsal carina which barely 
separates the two. The remainder of the abdomen is unmarked, probably the 
spots having faded from decomposition. 
Anal appendages short, lanceolate, brown. 
Wings hyaline but a little enfumed and saliated ; stigma reddish brown, 3.5 
mm.; membrane ashy white at the base, pale brown along the lower border ; 
trigone with 6 cells in the forewing, 5 in the hind; all hypertrigones traversed 
15-23 | 24-18 
-——— ; loop with 10-17 cells; 7 to 8 cubital
