142 I. AHMAD 



slightly convex, with a backward spiny process on either side on lateral extremities, concealing 

 about two-thirds of pygophore ; pygophore rounded, curved near apex, posterior margin 

 slightly concave (Text-fig. 451). 



o* genitalia : Claspers symmetrically placed (Text-fig. 451), dorsal and ventral thecal 

 appendages present ; two pairs of lateral conjunctival appendages (Text-fig. 453) asymmetrical ; 

 frontal conjunctiva with bunches of spines, usually about fifteen, second right lateral conjunc- 

 tival appendage thicker at base and near apex, curved in middle and pointed at apex ; mem- 

 branous appendage with an elongated irregular dorsal appendage (Text-fig. 453).

Very similar to $ in general appearance but distinctly larger ; seventh abdominal sternum 

 and genital structures usually pale, tinged brownish black. Posterior margin of seventh 

 abdominal sternum emarginate, with a median split and a large median fold making two smaller 

 lobes, one on each side at extremities, with a backward spiny process on each side (Text-fig. 



454)- 



$ genitalia : First gonocoxae large, seen from outside, broader than long, almost conical 

 in form, with lobe-like apices and medially curved and concave external margin (Text-fig. 458). 

 Intervalvular sacs absent (Text-fig. 459) ; spermatheca elongated, flat and hump-shaped near 

 apex (Text-fig. 455).

This species is completely isolated in the genus and can be easily separated from 

 other species by its entirely brownish black hemielytra, by brownish black dorsum 

 of abdomen, black transverse lines on the ventral side of abdomen, long rostrum 

 extending well beyond hind coxae and by pale colouration of basal half of apical 

 segment of antennae. This species shows some relationship with Cosmoleptus 

 limbaticollis (Sta.1) in having similar shape and colouration of pronotum and almost 

 similar form of the apical antennal segment. 



Noliphus spinosus sp. n. 



(Text-figs. 460-468) 



Characterized by the black propleuron, pronotum and usally black underside of 

 head and two round and smooth black dots in succession on either side of venter of 

 abdomen, by the short basal segment of antennae, and by the form of $ and $ 

 genitalia.
