 1907, p. 23. 



Genotype : fo (Walk.). 



Imago. — " $$. Closely allied to Apocalypsis. Eye lashed. 

 Antenna of 9 almost cylindrical, with the basal rows of 

 fasciculate cilia vestigial. First segment of hind tarsus 

 shorter than tibia, not longer than segments 2 to 5 together, 

 twice as long as long terminal spur of hind tibia. 



" o- Tenth tergite elongate, tapering to end, \yhich is 

 somewhat obtuse ; sternite much broader, triangular, the 

 sides turned upwards, hence the under surface convex, apex 

 more or less distinctly sinuate. Clasper without patch of 

 modified scales ; inner surface covered distally with hair- 

 scales which lean basad ; harpe covered with suberect, short 

 scales, except at end. Penis-sheath with a single long, 

 pointed tooth which is directed dextro-laterad, pointing 

 somewhat proximad. 



" $. Vaginal cavity large, mouth subcircular, in and before 

 middle, the edge somewhat raised, without lobes ; post vaginal 

 part of plate (fig. 16 G) chitinized in middle " (Roths. & 

 Jord., 1903, p. 100).
