c? ? . Distal margin of forewiiii;' iKit, niulnliite as in the two preceding species, 

 shallowly sintiate before posterior angle. Second segment of palpus rather smaller 

 than iu the other species. Row 2 of spines of first segment of hindtarsns extending 

 close to the base as iu Psilogramma. 



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

 regularly curved downward and gradually narrowed to a jioint (PL XXV^I. f. 33) ; 

 the processes ajiproach each other a little iu middle ; the steruite is produced into 

 a long cylindrical i)rocess, 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, multideutate, ribbed scales ; 

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

 groove of clasper sharply defined, deep, the fold below it witli long bristles. 

 Penis-sheath with one pointed process (PI. XXVIII. f. 35), which is ratlier broad 

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



?. Vaginal jilate (PI. XXI. f. 15) very feebly chitinised, the whole postvaginal 

 2)art membranous and scaled, the autevagiual part also membranaceous ; from the 

 vaginal cavity a narrow stripe of chitin 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 JShyanoton and PsiloiininiiiKi.

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

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

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

 spinosc 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 5 ; hindtarsus 

 twice as long as the cell of the hindwing, first segment U to 2 times the length 

 of segments 2 to .5 together ; spurs very long, apical one of hiiidtihia at least
