lar. Wings with four apical cell elongate-triangular with a very 
short basal stalk. 
This genus is near Quilessa , but differs in the shape of the 
vertex and of the frons, in the presence of a distinct pronotal 
disc bounded by carinae, in the pronounced curvature of the 
veining at the apex in the tegmina, in the relatively more elon- 
gated and shorter-stalked fourth apical cell in the wings, in the 
wider lateral lobes of the male anal segment and in the basic 
form of the aedeagal armature. The four known species of 
this genus agree in possessing a small dark spot at the basal 
end of the stigma and a second dark spot in the third apical cell 
of M, but this character may not be of significance in identify- 
ing the genus. 
Atopocixius collaris sp. nov. 
(figs. 7, 26, 29, 44-46) 
Male. Length, 1-8 mm.; tegmen, 2.0 mm. 
Female. Length, 1-9 mm.; tegmen, 2.1 mm. 
Scutellar portion of mesonotum scarcely depressed. 
Vertex, frons, clypeus, anterior margin medially and lateral 
fields of pronotum, tegulae, mesonotum except on lateral mar- 
gins and scutellum, postfemora except at base and apex, and 
abdominal sclerites piceous; lateral margins of vertex at base, 
lateral margins of frons in apical half, genae below antennae, 
rostrum, upper surface of pronotum, tip of scutellum and legs 
whitish yellow; lateral margins of mesonotum orange brown; 
membrane of abdomen red. 
Tegmina fuscous; distal half of costal cell except for an ob- 
lique fuscous band, middle portion of first subapical and apical 
cells from stigma as far as M2, a narrow spot overlying vein 
forming base of second apical cell of M, hyaline, the interven- 
ing veins heavily infuscate except at node; base of tegmen, 
scutellar margin and a small triangular spot at apex of clavus 
pallid yellow; a dark fuscous spot at base of stigma and another 
at base of third apical cell of M. Wings hyaline, veins fuscous. 
Anal segment of male with lateral lobes broad produced be- 
yond anal margin scarcely or not incurved distally. ^Edeagus 
with a slender sclerotised rod in middle line dorsally, a sinuate 
distally bifurcate spinose process arising near middle of ventro- 
lateral margin on each side, directed obliquely backward and 
outward; a pair of vertical spinose processes at apex, slightly
