scales similar to those on elytra. Tibiae almost straight, scales simi- 
lar to those on elytra. Tarsal claws connate for approximately the 
basal two-fifths and slightly divergent. Scutellum small, barely vis- 
ible, covered with small scales. Median lobe of male genitalia 
slightly over two and one-half times longer than its width at base, and 
somewhat shorter than its struts (fig. 79). Dorsal and ventral sur- 
faces of the median lobe much more lightly sclerotized than sides; 
sides slightly divergent toward apex but otherwise subparallel ; internal 
sac constricted near middle, the apical section armed with small dark 
spines (fig. 79). Spiculum gastrale curved and broadened at the 
anterior end but not hooked (fig. 79). Female genitalia with a Y- 
shaped spiculum gastrale with unexpanded stem; vagina completely 
membranous (fig. 129).
