of April, 1914. That they were viviparous females was made out by dissecting 
young embryos from their bodies. 
- Body ovalish, with a much less covering of meal; colour dark green, almost 
black. 
Head, antennae, thoracic bosses, sternum, legs and-rostrum all black. 
The antennae arise from pits on either side of the medially grooved front. 
The antennal spur is large, its terminal part a little thicker and beset with a few 
spines. 
Article III thickest and longest, unlike the apterous viviparous female.

Lenpths 2° 0:25 0'IO O'I4 0‘15 +006 mm. 
Sensoria : 10-13 irregular sensoria are borne in a line on III and 2-3 on IV; their 
membrane is dotted and often two are united together. 
The prothoracic edge anteriorly is black and flattens on either side into larger 
dots; there is also another smaller band on the middle. 
The metathoracic bosses are shining black, rather flattish and broad.' 
Wings voluminous, hyaline, having brown veins; costa and subcosta including 
insertions black. The posterior edge of the stigmal flattening is dark gray and swol- 
len uniformly. The stigmal vein exhibits a slight curve. The first and second dis- 
coidal arise from a common point; the cubitus is simple and obsolete in its basal part. 
The posterior wings have two oblique veins. . 
The abdomen bears the same pattern of glands, but they are small; the lateral 
sides are wavy due to the well marked segmentation. 
Lateral tubercles are present as in the apterous female. 
Anus dorsal; the narrow ridge-like cauda and black vertical anal plate are all 
similar to those of the apterous viviparous female described above. 
Legs a little larger, otherwise similar. 
Rostrum short and thick, just reaches to the middle of first and second coxae.

Glands — These are in most cases circular or flattened oval in form; in young 
females about to moult they assume a dark colour and are very clearly marked on 
the cast-off skin. Each consists of a smaller or larger number of rounded or somewhat 
angular facets, on which the hypodermal glands open and pour their secretion in the 
' [Mr. Das does not mention if there are any wax-glands present on the thorax, which is very likely 
to be the case here. P.v.d.G.).
