njiou the ujiperside of the midtibiii. The stnicture beinj;' the same as in phalaris, 

 we cannot entertain any Aloubt that, ci'i-tiiia is specifically the same as phalaris. 

 Other North Indian individuals are much redder and the pattern of the forewing 

 is more obviously marked. 



The species cau be distiuguished by the following characters : . . 



S%. Midtibia not wliite above like the hiadtibia ; this uearly as loog as the 

 tirst and second tarsal segments together ; short spurs not half the length of the 

 lung ones, these not half the length of the first tarsal segment. Distal margin of 

 forewing about 3 mm. shorter than the inner margin in both sexes. The pale costal 

 area of the forewing distally limited behind by vein R-, always extending beyond B,'. 



6. Tenth abdominal tergite similar to that of titan (PL XXIV. f. 1), but 

 tlie two apical hooks proportionally longer ; the sternite resembling that of cKroa 

 (1*1. XXIV. f. :.'), but mesially more rounded, as regards outline standing about 

 midway between the sternites of ciiron and titaii. The harpe (PI. XXXII. f. lo) 

 consists of a ventro-snbmesial jilate which is raised into a submesial ridge ciii. ; this 

 ridge is basall_r prolonged into a sliarply pointed long hook jib, and distally into a 

 broad, apically rounded process which is somewhat concave on the broad side ; the 

 edge of this process is raised distally and veutrally, running down to near the edge 

 of the clasper, while on the underside the process bears a fold f, which connects it 

 with the inner sheath of the clasper, the fold disappearing in a patch of very irregnlar, 

 strongly curved, small folds ; the dorsal jjrocess pd of the clasper is ribbon-like on 

 the ujjperside, rather pointed ventrally at the end and irregularly denticulate ; 

 between this process and the harpe there is a rather conspicuous fold. 



?. The eighth tergite (PI. XVI. f. 10) is swollen and rounded laterally ; it 

 dues not project distad over the scale-bearing membrane. Vaginal plate (PI. XVI. 

 f. 3) with a transverse fold before the vaginal orifice : the postvaginal part of 

 the jjlate projecting distad as' in the other species, its apical margin sballowly 

 sinuate. 



Larva green, with oblique whitish side-bands, granulose, granules especially 

 large on head, legs, and anal segment. Young : head triangular, horn long. 

 Adult : head very large, round, horn reduced to a short triangular lobe. 



Pupa figured, but not described ; of the ordinary type, special characters 

 not known.

 latter as long as (<?), or (?) I mm. longer than, the first tarsal segment ; short 

 s]iurs barely one-third of the long ones, little longer than the tibia is broad.
