The lateral one ot these apical lobes is divided into two small points, the mesal one clavate with several small, spiny processes. Cerci long, curved outward near apex and having a cluster of long setae along their dorso-lateral margin. The cerci and the ventral rods of the tenth tergite seem to be fused with each other and with the remainder of the tenth tergite at their base. Oedagus simple, composed of a basal tube in which articulates a slender sclerotized rod. Holotype, male.—Elkmont, Tennessee: June 12, 1935, H. H. Ross. Agapetus debilis new species This species is readily distinguished from other members of the group by the long and bidigitate claspers combined with the short tenth tergite. Male.—Length 6 mm. Body dark brown; the raised areas of the head and thorax, most of the anterior aspect of the head and legs below coxae straw color (except spurs, which are dark brown). Wings uniformly dark brown, the veins darker than the membrane. General characteristics as forjgenus except as follows: Front wings with radial crossvein oblique but with vein R2+3 hardly at all angled at that point; base without a large specialized area such as in Glossosoma. Legs with tibial spurs very long, all of them simple, their count being 2-4-4. Fifth sternite of abdomen without the usual compli- cated platelike appendage but with a raised area on each side connected by a raised line which runs transversely across the segment about one-third the distance from the apex. Sternites 6 and 7 with only small raised processes ending in a small point at apex. Genitalia as in f
