13. Acropteris parvidentata moluccana, subsp. n. 
3 2 .—47-53 mm. 
Distinguished from D. parvidentata, Warr. (Nov. Zool. iv. 
p. 199, Lombok and Cstsbaay, as follows :— 
Fore wing with the costal edge more weakly and minutely 
dotted, the dots in general wanting entirely from middle to 
near apex; particularly noticeable is the great reduction of 
the apical dots. The double lines from hind margin towards 
apex generally remaining well separated at the point at which 
they fade out near apex. Both wings with the markings 
on an average slightly greyer than in p. parvidentata, the 
terminal line in the typical (Obi) form obsolescent or strongly 
interrupted, but much better developed in that from the 
S. Moluccas, which might perhaps be again separated 
racially. 
Obi, July-September, 1918 (W. J. C. Frost); 4 3 od (in- 
cluding type) and 1 ¢ in coll. Joicey. Also from Amboina, 
Ceram, and Gisser Island (near Ceram), in coll. div. 
XLI.—Odonata collected in Mesopotamia by the late Major

Just after the completion of my notes on ‘Odonata from 
Mesopotamia ” (‘ Entomologist’s Monthly Magazine,’ 3rd ser. 
vol. v. pp. 143-151, 183-196, 1919), Dr. Gahan kindly gave 
me the welcome opportunity of examining another large 
collection of these insects from the same region, brought 
together by the late Major R. Brewitt-Taylor, R.A.M.C., 
presented to the British Museum by Mrs. Brewitt-Taylor. 
Major Brewitt-Taylor was apparently a novice as far as 
dragon-flies were concerned, but he had taken up the subject 
with a rare enthusiasm and with some originality, and his 
notes and descriptions made from the living insects gave 
promise of better things if he had been spared to continue 
the work. Preservation of the striking colours of the living 
insects had evidently been one of his chief aims, and in this 
he succeeded in quite a marked degree, to this end a large 
number of his captures having been carefully eviscerated. 
As a result of this treatment, for example in the case of
