ATYPOPHTHALMUS. LIBXOTES. 409 



a large squarish brown dorsal plate, with the corners rounded and 

 the hind margin einarginate, with stiff black hairs on its clorsum 

 and long yellow hairs on the hind margin ; the large first joint of 

 the claspers is irregularly shaped, longer than broad, narrower 

 apically, where from an invaginated recess issue from each joint a 

 strong black hook and a moderately long, cylindrical, yellowish 

 appendage of softer texture, with a hairy tip ; a very distinct 

 inner pair of two- jointed claspers, the first joint approximately 

 ovate, narrower at the tip, the 2nd joint evidently hard, horny, 

 shining brown, in the shape of a long hook ; there is also a peculiar, 

 large central piece, apparently fleshy, yellowish in colour, with an 

 obtuse tip which reaches posteriorly not beyond the 1st joint of 

 the inner pair of claspers ; this central piece enlarged below into 

 a sort of cup-shaped cavity faciug hindwards, and apparently 

 attached to the root of the hypopygium immediately above the 

 ventral V-shaped plate.* Ovipositor of the female apparently 

 normal but somewhat large, especially the basal portion. Legs 

 brownish yellow, tips of femora darker. Wings pale grey ; venation 

 practically normal. Auxiliary vein ending nearly half-way between 

 the beginning of the 2nd vein and the tip of the 1st longitudinal 

 vein ; discal cell nearly square, about as long as the 2nd and 3rd 

 posterior cells, its inner side in a direct line with the posterior 

 cross-vein. Stigma distinct but ill-defined, blackish ; a faint small 

 infuscation at the base of the 2nd vein. Halteres yellow ; clubs 

 blackish. 



Length 4^-5 millim. 



Described from a male and female taken by Dr. Annandale 

 in Calcutta, the male (8. ix. 10) in a spider's web, the female
