below and at the apex ; the upper lateral lamellæ are reddish brown, 



they are somewhat swollen in the middle and project forwards with 



a blunt process and backwards with a somewhat downwards declining- 



process; both processes are short and both are curved towards each 



other, thus leaving an oval opening between the upper lamellæ through 



which the end of the penis goes; the lamellæ are short haired in the 



upper margin. Penis is a long, simply curved thread, somewhat 



thickened at the base, of ferruginous colour. The eighth ventral 



segment is arched and points backwards 



with a free margin, beset with long hairs 



(anus hians), penis ascends from its lower- 



most part; above the segment forms two 



somewhat triangular lamellæ, one on 



each side, beset with long and strong, 



black bristles; in the opening of the 



segment, above the base of penis and 



below the mentioned process a globular 



body is seen. Legs black or sometimes
