 is more obviously marked. 



The species can be distinguished by the following characters : 



cj?. Midtibia not white above like tlie hindtibia ; this nearly as long as the 

 first and second tarsal, segments togetlier ; short spurs not half the length of the 

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

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

 area of the forewing distally limited behind by vein 11-, always extending beyond R^ 



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

 the two apical hooks proportionally longer ; tlie sternite resembling tluit of i 'iron 

 (i'i. XXIV. f. '-'), b>it mesially more rounded, as legards outline standing about 

 midway between the steruites of euroa and titun. The hnrpe (PI. XXXII. f. I'l) 

 consists of a ventro-submesial plate which is raised into a submesial ridge cm ; thi> 

 ridge is basally jirolonged into a sharply pointed long hook jjIj, and distally into a 

 broad, a])ically rounded process which is somewhat concave on the broad side ; the 

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

 of the clasper, while ou 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 irregular, 

 strongly curved, small folds ; the dorsal process pd of the clasper is ribbou-like on 

 the upperside, 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 

 does not project distad over the scale-bearing memljrane. Vaginal jilato (PI. XVI. 

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

 the plate projecting distad as in the other species, its apical margin shallowly 

 sinuate. 



Larva green, with oblique whitish side-bands, grauulose, 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 tiie ordinary type, special characters 

 not known.

 latter as long as (J), or (?) 1 mm. longer than, the first tarsal segment ; short 

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