2 and 3). The adult (apparently female), nymph, and work, 
as they occurred in India, have been beautifully figured in 
colors by H. M. Lefroy (’09:742, pi. 80, figs. 2-5), and the 
insect and its host plant casually mentioned in the text, but he 
evidently did not recognize it then as a new species. The first 
taxonomic description of this species was published by Crawford 
(’12) from six females bred on “pumpkin” and on Alstonia 
scholaris. The adult male and the nymphs are described for 
the first time in the present paper.

gin of IV ; a small, subcircular red spot on laterocephalic angle 
of abdominal stemite III. An elongately subrhomboid brown 
spot, intercepting a median, elongate, white band, running from
