length, almost symmetrically rounded at tip; clavus not granu- 
late. Costal cell wide, slightly expanding apically, Sc+R joined 
to near stigma, common stalk Sc+R+M half as long as basal 
cell. Typically eight apical cells, the anterior trapezoidal, sec- 
ond quadrilateral with straight sides, third small, triangular, 
fourth elongate, rectangular, fifth triangular, sixth elongate, 
wedge-shaped, seventh triangular, eighth pentagonal; a sub- 
apical series of three cells, the first forming a quarter circle, 
second subrectangular and third quadrilateral; clavus joining 
commissural margin about two-thirds from base of tegmen. 
Genotype, Lomagenes delphacoides sp. nov. 
This genus is near Quilessa but differs in possessing no me- 
dian carina on the clypeus and an angulate carina on the vertex 
with a sunken area behind it. 
Lomagenes delphacoides sp. nov. 
(figs. 8, 9,23,24,32) 
Female. Length 2.0 mm.; tegmen, 2.7 mm. 
Vertex, except carinae, base of frons, upper surface of pro- 
notum except anterior margin, fuscous; carinae of vertex, basal 
half of frons, clypeus, thoracic pleurites, anterior margin of pro- 
notum, margins of mesonotum, tegulae, reddish-brown; apical 
portion of frons, genae below antennae, legs, valvulae of oviposi- 
tor, testaceous; mesonotum and scutellum fuscous-piceous with 
a faint greenish iridescence; abdomen piceous. 
Tegmina hyaline, slightly suffused yellowish-brown on clavus 
in basal third and apical quarter; veins and margin testaceous- 
fuscous. Wings hyaline, veins fuscous. 
Pregenital plate quadrate, slightly more than twice as broad 
as long, anterior margin transverse, minutely crenulate, lateral 
margins in ventral view slightly diverging posteriorly, feebly 
convex, posterior margin transverse or very shallowly concave. 
Third valvulae of ovipositor broad, tapering distally to a blunt 
point, dorsal margin almost straight, ventro-apical margin ob- 
lique. First valvulae narrow, bluntly rounded distally.
