dusky pigment. At their ends near the margins the flattening of the nervures is 
conspicuous ; the cubitus after its first fork bends sharply and the two branches of 
the second fork are equal. Stigmal vein hardly visible near its basal end, but a cloud- 
ing at the distal end is always present, the wing appearing speckled. The hindwings 
also have similar clouding at the apex of the wing and vein ends. 
The pattern on the abdomen is slightly different, but in the main is the same as in 
the apterous female ; on the first three abdominal segments the blackish glands of the 
middle pair are large and confluent with their fellows, and form a straight or slightly 
crescentic band quite raised above the level of the abdomen, as shown in the plate. 
The glands on the carina make the contour of the abdomen wavy. On the hind seg- 
ments the glands again become larger than those of the middle segments which have 
them only faintly marked, while on the penultimate Segment all are confluent in a 
single mass. . 
The cornicles are like rings ; rather large, with a distinctly double outline. 
The cauda and anal plate are exactly like those of the apterous female. 
The legs are more dusky and possess larger flocculence. 
The rostrum is small, just reaching to the black sternal bosses. On the ventral 
surface just above the coxae a black blotch is noticeable a little on the lateral side ; 
the segmentation of the abdomen is much more marked on this side.

Glands.—Each gland consists of a large 
number of more or less regular polygonal plates, 
grouped together into a rounded elevation. 
Over the surface of each plate are present from 
5 to 8 small black dots or pores from which the 
flocculent secretion exudes in the form of very 
fine threads. They either retain their long 
form for a considerable time and give rise, by 
their coming together, to the larger threads or 
hairs already noticed, or break down and form 
the cottony mass. . 
The plates near the anal end and on the 
head are a little larger ; the number of pores on 
the surface also is greater and the majority of 
them are disposed in a circle round a single cen-
