A. A. GIRAULT. 33 



not especially wide or long, bearing the three ocelli in a tri- 

 angle in its center near the occipital margin, the lateral ocelli 

 somewhat their own width apart from the eye margins ; eyes 

 ovate. The thorax and abdomen about equal in length, the 

 latter sessile, short, stout, obliquely truncate ventrad, ovate, 

 the whole body well proportioned, the ovipositor not ex- 

 serted, the tips of the hypopygium visible but not exserted. 

 Parapsidal furrows complete, widely separated ; mesoscutel- 

 lum transverse elliptical in shape, distinctly shorter than the 

 scutum ; pronotum very narrow. Legs normal, the three 

 joints of the tarsi short, subequal in length, the proximal 

 joint somewhat the shortest, the tibial spurs single, the poste- 

 rior femora broader than the others. Tibial spurs of the 

 cephalic legs not curved and forked to form a strigil. 



Antennae 7-jointed* — scape, pedicel, one shallow ring-joint, 

 one funicle joint and a 3-jointed club ; all of the joints wide, 

 the funicle somewhat the widest or as wide as the widest 

 portion of the club, the club as long as the pedicel and funi- 

 cle united, the funicle as long or longer than the pedicel ; 

 and the scape cylindrical and the next longest joint after the 

 club ; pedicel and scape narrower, the funicle joint distinctly 

 wider than the pedicel ; funicle apparently divided obliquely 

 into two joints, globular to subquadrate ; ring-joint exceed- 

 ingly short, thin, saucer-like. 



Fore wings (fig. 10) short and broad, oblately rounded at 

 the apex, broadest at their distal sixth or just proximad of 

 the apex, far distad of the apex of the venation, shaped like 

 a fiat broad paddle but not as broad as in Chaetostricha ilavi- 

 pes (Girault) for instance, nearly as in the genus Uscana 

 Girault ; at their greatest width not more than twice longer 

 than wide, across the marginal vein four times longer than 

 broad ; hyaline, the discal ciliation moderately dense, normal 

 with the exception of six longitudinal widely separated radiat- 

 ing lines which, though not separated themselves from the 



* I have had great difficulty in determining the antennal structure of 

 this genus ; the ring-joint is present but escapes certain detection very 

 easily, while the apparently large single funicle joint has a peculiar 

 twist to it as if divided obliquely but I cannot detect articulation here, 

 merely thickening due to the twist.
