sal margin almost straight, ventral margin strongly convex, truncate 
dorsoapically with a slight projection at dorsal angle. 
Described from one male collected by D. Farrell, St. Augustine, 
Trinidad, B. W. I. (1920). Material in B. M. N. Hl. This species is 
distinguished by the venation of the tegmina and wings, by the struc- 
ture of the aedeagus, and by the color. 
Genus BIOLLEYANA Distant 
Biolleyana DIsTant, Ann. Mag. Nat. Hist., ser. 8, vol. 4, p. 335, 1909. (Genotype, 
Nogodina pictifrons Stal, Ent. Zeit. Stettin, vol. 25, pp. 53, 369, 1864.) 
Head with eyes about as broad as pronotum, vertex short, more than 
twice as broad as long, lateral margins parallel, raised, anterior margin 
carinate, angulately produced anteriorly, posterior margin roundly 
excavate; frons longer than broad, lateral margins almost parallel, 
diverging very slightly from base to apical three-quarters, then in- 
curved to frontoclypeal suture, slightly raised, median carina distinct, 
lateral carinae feeble; clypeus tricarinate. Pronotum with anterior 
margin strongly convex, posterior margin broadly excavated; meso- 
notum with median carina distinct, lateral carinae present, curved 
mesad basally, subparallel along sides of disk, then curved mesad 
anteriorly to meet rather acutely at middle line. Posttibiae with four 
or five spines. Tegmina rather broad, expanding distally, vitreous, 
veins prominent, a series of transverse veins between costa and margin, 
Sc and R with a common basal stalk longer than basal cell, M fork, fork 
of Cu, and junction of claval veins at about same level, nodal line, 
subapical line and apical line of transverse veins present, a transverse 
vein in clavus between claval suture and anterior claval vein at basal 
third. Wings with a fairly even line of subapical areoles and an evener 
row at apical margin. 
BIOLLEYANA COSTALIS (Fowler) 
PLATE 14, Fieures 419-422; Pirate 15, Ficurres 423-432 
Sassula costalis Fow Ler, Biologia Centrali-Americana, Rhynch. Hom., vol. 1, 
p. 68, 1900. 
Male: Length, 8.2 mm.; tegmen, 10.7 mm. Female: Length, 8.5 
mm.; tegmen, 11.5 mm. 
Vertex about three times as broad across base as long in middle; 
frons about one and a half times as long as wide, lateral carinae ob- 
solete on apical third. 
_ Fuscous, abdomen and legs paler; tegmina hyaline, usually a spot 
on costal membrane at basal third, a spot at basal M-Cu, cross vein, a 
short line from stigma along nodal line to M, and three or four diffuse 
patches distad of subapical line dark fuscous; wings with apical cells 
_infuscate except for a clear spot in M.
