Antennae black, arising from depressions ; they are very short, hardly reaching 
beyond the anterior third of the body ; the joints are well marked and intricate. 
The spur is only slightly smaller than the base.

Sensoria are present on articles III and IV, from 3 to 5 and ı to 2 respectively. 
The prothorax has a large lateral tubercle and three spots on the dorsum. 
The mesothorax and metathorax have their median and lateral spots Pr 
large; they almost form one continuous blotch in some individuals. 
The abdominal segments possess lateral tubercles the largest of which are 
situated on the first and seventh segments. The others are small but black and in 
macerated mounts come out exactly like sensoria. Fach black tubercle appears to be 
associated with a small sensorium. 
The posterior segment frequently overlaps the cauda. 
Cornicles black, imbricate, somewhat truncate conical, not quite cylindrical as in 
the type of this genus. The base is about two-thirds the length and the apex less 
than half. It is about one-tenth of a millimetre long. 
Cauda broad-based, somewhat conical; apical portion black, basal hyaline except 
the edges. It is about as long as its breadth at base; a little longer than the 
cornicles in the ratio of 3 to 2. 
Anal plate conspicuous black, rounded posteriorly. - 
Genital plate somewhat overlapping ; a little larger and concave anteriorly. 
Rudimentary gonapophyses three in number; the central one the largest and 
beset with a few spines. 
Legs rather short and stout, dark brown; tarsi and precoxal areas black. 
The rostrum reaches up to the middle of the 2nd and 3rd coxae.

Alate viviparous female.—Body ovate, mealy. 
Colour similar to the apterous viviparous female. 
Antennae, head, prothoracic band, mesothorax, legs, cauda and cornicles all black. 
The pattern on abdomen is also similar to the apterous viviparous female, except 
that on carinae in front of the cornicles there are three large circular spots and a 
small one near the base of the cornicles. The rectangular blotch is absent, but on the 
margins there is just another row of tiny dots in addition to the median and lateral 
ones. 
Head broad, with prominent eyes and ocelli.
