CLAN IS. 



143: 



g. Tenth abdominal tergite similar to that of titan, but the 

 two apical hooks proportionally longer ; sternite resembling 

 that of euroa, but mesially more rounded, as regards outline 

 standing about mid-way between the sternites of euroa and 

 titan. The harpe (fig. 28 A) consists of a ventro-submesial 

 plate which is raised into a submesial ridge ; this ridge basally 

 prolonged into a sharply pointed long hook, and distally into 

 a broad apically rounded process which is somewhat concave 

 on the broad side ; the edge of this process raised distally 

 and ventrally, running down to near the edge of clasper. 



Fig. 29. — Clam's ph alar is (Cram.), resting attitude. 



while on the underside the process bears a fold which connects 

 it with the inner sheath of clasper, the fold disappearing 

 in a patch of very irregular, strongly curved, small folds : 

 the dorsal process of clasper ribbon-like on upperside, rather 

 pointed ventrally at end and irregularly denticulate ; between 

 this process and the harpe a rather conspicuous fold. 



9. Eighth tergite swollen and rounded laterally ; it does not 

 project distad over the scale-bearing membrane. Vaginal 

 plate (fig. 28 B) with a transverse fold before vaginal orifice ; 

 the post-vaginal part of the plate projecting distad as in the 

 other species, its apical margin shallowly sinuate.
