Fig. 128—135.— Rrachylinga baccata (Coq.) male terminalia, 128. — Gonocoxites and hypandrium in ventral view. 129. — Left gonoccxite with appendages and aedeagus in dorsal view. 130. — Left gonoccxite and gonostylus in lateral view. 131. — Epandrium with appendages in dorsal view. 132. — Ventral epandrial sclerite. 133. — Aedeagus in lateral view. 134. — Sternite 8. 135. — Tergite 8. Scale; mm. with a darkened area around stigma in some species and darkened areas sur- rounding the veins in a few species. Legs. — Fore femur has 0-1 av setae (usually 1) ; middle femur has no setae; hind fe- mur has a sparse row of av and pv setae; scalelike, appressed as well as thin, erect pile on all femora. Abdomen. — Slender (especially in male), tapering toward apex, cylindrical in cross section; pile sparse, semi-ap- pressed in most species; tomentum sparse, usually silvery along sides of fe- males, covering all of doreum in males of most species {B. pavida males lack this feature). Ground color often dark brown or black. Male Terminalia (Fig. 128-135).— Segment 8 from slightly to greatly re- duced; sternite 8 (Fig. 134) a rounded sclerite, notched on the posterior margin; tergite 8 from narrowly constricted (as in B. pavida) to broadly constricted (as in B. baccata (Fig. 135) and B. abdotn- inalis). Epandrium (Fig. 131) of mod- erate size, usually wider than long, ratio of length/width along midlines from to ; posterolateral margins not modi- fied; cerci as long as to considerably shorter than ventral epandrial sclerite and usually free from one another; ven- tral epandrial sclerite (Fig. 132) simple, often notched apically, usually relatively large with respect to cerci; interseg- mental membrane basad of ventral epan- drial sclerite weakly sclerotized, with small, lateral shields fitted into postero- ventral portion of epan
