(? ? . Distal margin of forewiiig nut undulate as in tlie two jirecediug siiecies, 

 shallowly sinnate before posterior angle. Second segment, of jialjius rather smaller 

 than in the other species. Row 2 of spines of first segment of hindtarsus extending 

 close to the base as in Psilogi-amnia. 



c?. Tenth tergite divided into two long and slender processes, which are 

 regularly curved downward and gradually narrowed to a j)oiut (PI. XXVI. f. 33) ; 

 the processes approach each other a little in middle ; the sternite is produced into 

 a long cylindrical process, which is slightly bent downwards at end, the apex obtuse. 

 Clasper sole-shaped, dorsal margin bent inwards ; the large clay-coloured patch 

 of modified scales on the outer side consisting of large, mnltidentate, ribbed scales ; 

 harpe ladle-shaped, minutely dentate (PI. XXXV. f. 14) ; subdorsal longitudinal 

 groove of clasper sharply defined, deep, tlie fold below it with long bristles 

 Penis-sheath with one j)ointed process (PI. XXVIII. f. 35), which is rather lu'oad 

 at base. Eighth tergite icitliout friction-scales on the inner surface. 



?. Vaginal plate (PI. XXI. f. 1.5) very feebly chitinised, the whole postvagiual 

 part membranous and scaled, the antevaginal part also membranaceous ; from the 

 vaginal cavity a narrow strijje of cliitin extends to each side ; the upper edges of 

 these plates continuous, forming an arcuate ridge which borders the vaginal cavity 

 behind ; the proximal edge of the cavity formed by a very thin membranous fold, 

 which is preceded by a stronger fold. 



Early stages not known. 



The species is a connecting link between Mi'ijanoton and F-^^ilognimma.

S ? . Tongue as long as, or shorter than, the body. Genal process about as 

 high as pilifer. Segment 2 of palpus as long as 1. Antenna with short hook, 

 penultimate segment much shorter than high. First segment of foretarsus multi- 

 spinose exteriorly at the base, as long as tibia, longer than segments 2 to 5 

 together, without obviously prolonged spines ; midtarsus with reduced comb, 

 segment 1 about one-third longer than tibia and than segments 2 to o ; hindtarsus 

 twice as long as the cell of the hindwing, first segment 1 i to 2 times the lengtli 

 of segments 2 to 5 together ; spurs very long, ajjical one of hindtibia at least
