344 Mr. G. C. Champion on the 
specimens of this insect have recently been sent by my son 
from W. Almora, from elevations between 7000 and 9000 ft. 
Two males have been dissected. Gorham’s description of 
I. viridescens was based upon two examples (4?) from 
“India.” The yellow base of the last abdominal segment 
mentioned by him doubtless refers to the pallid membranous 
space visible between the ventral segments 5 and 6 in @. 
20. Idgia andrewesi. 
Prionocerus (Idgia) andrewesi, Bourg. Ann. Soc. Ent. Belg. li. p. 104 
(1907). (3 2.) 
3. Eyes extremely large, almost contiguous (narrowly 
separated in 9); anterior tarsal joints 1-3 with a comb 
along their inner edge, 4 narrow, small; posterior tro- 
chanters acuminate at tip (obtuse in 9). Genital armature 
(Pl. XI. fig. 17): median lobe rather broad, as seen from 
above, narrower than the lateral lobes, sinuate, acuminate 
at tip, the latter subtruncate; lateral lobes moderately 
broad, the concave apical portion, as seen from beneath, 
separated from the rest by an oblique fold. 
Hab. S. Invra (Mus. Brit.), Nilgiri Hills (H. L. Andrewes, 
Sir G. F. Hampson), Anamalai Hills (H. L. Andrewes). 
An elongate, uigro-cyaneous insect, with a long, flavo- 
testaceous prothorax, the basal joints of the antenne, and 
also the apical one, the palpi, and sometimes the scutellum 
in part, flavescent; the antenne long and slender, with 
joint 11 sinuate, considerably elongated in g; the apical 
joint of the maxillary palpi long; the head somewhat pro- 
duced in front ; the labrum narrow, somewhat oval, about as 
long as broad in some specimens, shorter in others. There 
are two males and six females of this species in Mr. Andrewes’s 
collection, and a pair in the British Museum. Bourgeois 
overlooked the tarsal and trochanter characters, which are 
conspicuous in the labelled type, ¢. The length varies from 
11-13 mm. 
21. Idgia chloroptera. 
Idgia chloroptera, Redt., Reise der Novara, ii. p. 111 (1868). 
3. Eyes large, subcontiguous (alittle more distant in @ ) ; 
anterior tarsal joints 1-3 with a comb along their inner edge. 
Genital armature (Pl. XI. fig. 18): lateral lobes long, broad; 
median lobe curved and acuminate at tip. 
Hab. Cryuon [type] (Thwaites, in Mus. Oxon.: 6), 
Kapulahani (Mus. Brit,: 3), Maskeliya (E. E. Green: 2).
