panding distally, then converging, with a bluntly rounded lobe pro- 
jecting posteriorly on each side at apex, ventral border with a pair 
of triangular plates at apex, each with a spine projecting a short 
distance beyond it. Genital styles in side view subovate, strongly 
excavated on dorsal margin toward base, with a short decurved tooth 
directed outward at middle of excavation, and a second tooth pointed 
anteriorly just distad of it. 
Described from one male specimen collected by Dr. J. G. Myers at 
Ocumare de la Costa, Venezuela (Dec. 17, 1930), and since sent to the 
British Museum. 
Distant has synonymized 7’. viridifrons Walker with 7. virata and 
Melichar gives the same synonymy. Melichar’s description of vitrata 
does not agree with the original description, whereas his description 
of suturalis Germar agrees with Fabricius’s description of vitrata, 
“caput atrum fronte rostroque fuscis: labio tamen atro. Thorax 
elevato lineatus, ater scutello apice fusco. Abdomen atrum margine 
fusco. Elytra hyalina margine postico fusco. Pedes fusci.” W. E. 
China states that the type of viridifrons appears to be missing.

Taosa bimaculifrons Murr, Proc. Hawaiian Ent. Soe, vol. 7, p. 470, 1931. 
Female: Length, 10.0 mm.; tegmen, 12.5 mm. 
Length of vertex slightly more than half width at base, vertex not 
projecting before eyes, anterior margin shallowly curved, triangular 
~ facet on each side anteriorly distinct, lateral margins almost parallel, 
basal margin shallowly excavate; base of frons visible from above, 
carinae of frons distinct except at base. Hind tibiae with four spines. 
Stigma with three cells. 
Green; a piceous quadrate spot overlying base of each lateral carina 
of frons; metanotum, a spot on metapleurites, protibiae and tarsi, 
metacoxae and trochanters dark brown; tegmina vitreous, veins green- 
ish, dark on membrane distad of nodal line, stigma greenish brown, a 
fuscous semicircular spot extending over three cells at apical margin, 
and slightly overlapping into a further cell on each side; wings 
hyaline. 
Ovipositor with first valvulae deflexed distally, then upturned api- 
cally, two recurved teeth on dorsal margin three-quarters from base, 
three much smaller teeth distad, directed posteriorly, and a pair of 
teeth at apex, curved upward, the distal tooth longer than the sub- 
apical tooth; second valvulae narrow, elongate, expanding before apex, 
rather deeply cleft at apex, the tip of each lobe pointed; lateral styles 
rather broad, dorsal margin shallowly concave, ventral margin convex, 
two processes at apex, directed caudad, a smaller process on apical
