on each side. Mesoscutellum about three-fourths as long as 
mesoscutum, about one and two-thirds times as wide as long, 
somewhat deflected caudad, roundly emarginate mesocephalad 
at cephalic margin, abruptly produced subconically ectad at 
anterolateral angles. Mesostemum slightly produced ventro- 
cephalad. Wings asymmetrically obovate, hyaline; apex some- 
what angular along direction of second marginal cell ; pterostigma 
and cubital petiole wanting; first marginal cell about twice 
as large as second; a small, elongately subtriangular area 
covered with coarse brown dots between branches of cubitus, 
one between branches of cubitus and media, and a third between 
branches of media. Hind legs slightly shorter than body; fore 
and middle legs somewhat shorter than hind; ungues broadly 
curved. 
Abdomen subequal in length to thorax, somewhat strongly 
deflected caudad, about one and a half times as long as wide, 
about as thick as wide. Anal valve about three-sixteenths as 
long as the whole of abdomen, about twice as long as diameter 
at base, truncately subconical, slightly constricted subdistad. 
Genital forceps subequal in length to anal valve, about one and 
a half times as long as diameter at base, vaguely retort-shaped 
with diameter of neck about half that of larger portion. 
Female. — Dorsal and ventral valves subconcolorous with the 
rest of abdomen, more densely pubescent than latter. Dorsal 
valve narrowly subconical, acutely produced apicad, more densely 
pubescent than ventral, about as long as the rest of abdomen, 
about three and one-third times as long as diameter at base. 
Ventral valve slightly shorter than dorsal, about twice as long 
as diameter at base. 
Newly emerged adults. — Bluish green. Eyes dark brown. 
Greenish yellow as follows : Antennal segments I and II ; meso- 
pleura and metapleura; mesostemites and metasternites ; legs; 
and, in male, genital forceps and anal valve. 
Nymph ( apparently full-grown). — Length of body, 2.12 
millimeters; width of head, 0.67; length of antenna?, 0.48; 
length of forewing pads, 0.8, width, 0.35; length of abdomen, 
0.96, width, 0.9. Bluish green, lighter on head. Eyes brick red. 
Body and appendages covered with a white waxy coating, very 
sparsely beset with moderately long hairs. 
Head slightly narrower than thorax, about two and a half 
times as wide as long, broadly rounded cephalad. Eyes 
subhemispherical, with caudal portions touching thorax, about 
three-eighths as thick as width of head. Antennae about
