PLATE 17, FIGURES 527-534 
Male: Length, 5.1 mm.; tegmen, 5.3mm. Female: Length, 5.8 mm. ; 
tegmen, 5.5 mm. 
Vertex depressed, broader than long in middle (2.3:1), anterior 
margin transverse, very slightly realure medially, basal margin 
shallowly excavate; frons slightly broader than long (1.1:1), hela 
tumid laterally at apex, median carina somewhat swollen in basal 
quarter, obsolete at apex. Pronotum with median carina obsolete; 
mesonotum feebly tricarinate. Hind tibiae with two spimes in ee 
half. Abdomen without paired eminences ventrally. 
Testaceous, suffused with reddish brown; middle and lateral mar- 
gins of frons, clypeus, a small suffusion at base of antennae, two 
triangular ae at apex of vertex, a triangular spot on each side of 
middle line of pronotum, and a crescentic mark on each lateral lobe, 
medial portion of abdominal sclerites, and a band near base and a 
second band near apex of profemora fuscous; eyes red, with a pale 
spot; tegmina yellowish, hyaline, mottled with pale fuscous, darker 
at base of Sc and M and near stigma, a broad irregular pale fuscous 
band from costal to commissural margin basad of humeral protuber- 
ance, an irregular line of rather large pallid spots obliquely from 
anterior margin in basal third to union of claval veins, a small pale 
spot at stigma, a distinct pale spot at junction of claval veins, and a 
pale spot on each side of anterior claval vein near base, transverse 
veins rather pallid. Wings smoky, veins concolorous, with narrow 
darker edges. 
Anal segment of male short, postanal portion longer than preanal, 
in profile porrect and narrow. Aedeagus tubular, curved distally 
upwards and bending caudad at apex assuming a spoutlike appear- 
ance, a long spine ventrally on each side, arising about two-thirds 
from base, about half as long as aedeagus, curving anteriorly, giving 
off a small spine near middle of upper edge. Genital styles with 
ventral margin straight, dorsal margin sinuate, strongly bent upward , 
distally, apical margin oblique, apical process of styles broad and 
blunt, bearing three small teeth. 
Anal segment of female short, postanal portion semiovate. Ovi- 
positor with lateral styles very broad basally, tapering rapidly to 
apex, which is subtriangular, rounded and incurved, membranous 
in texture; first valvulae broad at base, tapering distally, with four
