the genae and in the very large wings. It is 
perhaps close to T. vanuae Kirkaldy, but I 
have seen no specimens of that species. 
Trioza propria n. sp. 
Fig. 3 
Length to tip of folded wings, 3 mm. 
Color: Head and thorax light brown dor- 
sally, remainder of thorax orange. Abdomen 
chocolate-brown dorsally, yellow ventrally. 
Genae creamy white. Legs very light tan. 
Wings milky. 
Structure: Almost glabrous, very small setae 
scattered over body. Head slightly wider than 
thorax. Postocular area large. Vertex with 2 
deep longitudinal sulci, caudal margin sharp, 
upraised, cephalic margin rounded down, 
bulgingly produced each side of medial su- 
ture. Eyes large, hemispherical. Genal pro- 
cesses short, about one-third as long as 
vertex, acute, somewhat divergent apically, 
not completely covering frons at base. An- 
tennae only slightly longer than width of 
head. Thorax quite flat longitudinally, very 
strongly arched laterally. Pronotum de- 
pressed far below vertex and mesonotum. 
Forewings about three times as long as wide; 
branching of basal vein in only specimen at 
hand not quite trifurcate, media and cubitus 
with short petiole, Rs smoothly curved to 
costa, cubital cell larger than medial. Hind 
wings 0.6 as long as forewings. Metatibiae 
with basal carina, 1 outer and 2 inner apical 
spines. 
Female genital segment large; ventral valve 
larger than dorsal, blunt, dorsal acute, 
darkened apically. 
Holotype female, Marianna Islands: Song- 
song-Regusa, Pagan, April 28, 1940, Yasu. 
et Yoshi. Type returned to Esaki. 
The genal processes of this unique speci- 
men are reminiscent of those of Neotrlozella 
although much shorter. The presence of only 
two inner apical spines on the metatibiae is 
rather uncommon in the species known from 
the Pacific.

aspect of female cauda. 
Trioza lyra n. sp. 
Fig. 4 
Length to tip of folded wings, 3.25 mm. 
Color: General color yellow. Incomplete 
longitudinal brown line medially on meso- 
scutum and scutellum. Metascutellum nearly 
white except for large brown O -shaped or 
lyre-shaped spot. Abdomen with narrow 
brown vitta dorsally, sternites light brown. 
Eyes red. Antennal segments dark apically. 
Structure: Body moderately pubescent 
throughout. Head as wide as thorax, post- 
ocular area small. Vertex emarginate and very 
abruptly margined caudad, with very promi- 
nent discal circular fovea each side of medial 
suture, latter very prominent, anterior margin 
bulging, rounded down to genae. Genal pro- 
cesses one-half as long as vertex, broadly 
rounded. Eyes large, hemispherical. Anten- 
nae almost twice as long as width of head. 
Thorax moderately arched. Pronotum de- 
pressed far below vertex and prescutum.
