294 Mr. K. J. Morton on 
Lindenia tetraphylla, quite a different conception of what the 
insect is like is given when a prepared specimen is compared 
with the usual dried ones. But for the reason above men- 
tioned the characteristic parts of the second abdominal seg- 
ment in the male and the valvula vulvz in the female have 
not been regarded, and have been sometimes completely 
removed or obliterated. 
In point of number of species, Major Brewitt-Taylor’s 
captures are less extensive than the combined collections 
previously dealt with, and only one additional species falls to 
be noticed, namely the wide-spread Pantala flavescens, which 
was rather unexpectedly wanting in the collections of Captain 
Evans and Captain Buxton. All are from Basra and Amara, 
the bulk of them being from the former locality, and the 
time covered comparatively short, the extreme dates being 
6th May to 14th August, 1916. 
A good series, in excellent preservation as to colour, of 
the small Crocothemis, which 1 had previously referred to 
C. erythrea, leads me to consider the Mesopotamian insect as 
distinct from that species, although decidedly belonging to 
the C. erythrea group. 
In the following list, to save undue multiplication of dates 
when the number of examples is large, each month has been 
divided into three equal parts, only the first and the last date 
in each part being quoted. 
Dr. Gahan, in forwarding the dragon-flies, also communi- 
eated Major Brewitt-Taylor’s note-book, from which I have 
made a number of extracts relating to the habits and the 
colours of the living insects. These are not only of interest 
and of use, but their preservation in this form may also serve 
as a small tribute to tie memory of the collector.

Six of the females of the orange form; three without 
orange, having the lower part of the thorax pruinose, one of 
them with imperfect black shoulder-stripes. 
Stated to be very common on banks of streams, and that 
both sexes come to light at night.
