bilobed caudally, the pubescent membranous lobes small; basis tyle 

 not broadened basally, mediangular process moderately developed; 

 dististyle stout, slightly curved, slightly attenuated in midportion 

 with stout, blunt tip; aedeagal sclerites bisinuate, slender, caudal sub- 

 median membranous lobes well developed; parameres each with 

 arcuate lateral lobe from base, main body poorly sclerotized, narrower 

 basad at juncture with basal lobe, distally stouter with an oblique 

 subapical concavity bearing a short point on lateral margin, the mesal 

 margin greatly produced in a tapering elongate sharp process. 



Distribution. — West Pakistan. 



Types. — Holotype male, allotype female, Peshawar, West Pakistan, 

 20 June 1958, J. Maldonado, light trap (USNM 69453). Paratypes, 

 2 males, 6 females, all taken in light traps. WEST PAKISTAN: 

 Peshawar, same data as types, 1 male, 2 females; June 1959, H. 

 Barnett, 2 females. Rawalpindi, Ayub Nat. Park, June 1959, H. 

 Barnett, 1 male, 1 female. Rawalpindi, Dhamyal, June 1959, H. 

 Barnett, 1 female. 



Discussion. — Stilobezzia obesa, new species, and macclurei, new 

 species, are similar to crassivenosa in general features and in the bifid 

 gross structure of the male paramere, but both obesa and macclurei 

 have the male dististyle with slender tip; in obesa the aedeagal 

 sclerites are more strongly swollen and sinuate, and in macclurei the 

 inner fork of the paramere is short and stout. Stilobezzia aureola 

 Clas trier from Algeria has male genitalia nearly identical with crassi- 

 venosa, but the subapical process on the paramere is free distally 

 from the rim of the concavity.
