plate a wide membranous tube, flattened and somewhat depressed 
dorsally, with dorsolateral margins curled upward and mesad, beset — 
with a row of six strong teeth recurved anteriorly, a deep cleft on each 
side apically between ventral plate and lateral borders and a deeper 
cleft between lateral borders and dorsal median lobe; penis consisting 
of two apodemes, narrow, tubular, approximated at base, separating 
distally, each with an oblique spine terminally. Genital styles rather 
elongate-ovate, with a prominent lobe in middle of dorsal margin, 
slightly incurved, and bearing four short curved teeth; on inner face 
basally a long slender curved process, truncate apically. 
Ovipositor with lateral styles broad, dorsal and ventral margins 
strongly and about equally curved to meet in a point at apex, apical 
membrane triangular, extending farther along ventral margin than 
along dorsal; first valvulae with two small spines on dorsal margin 
two-thirds from base, two long spines at apex, a large triangular lobe 
ventrally, underlain by a short thick triangular setigerous lobe. 
Described from one male and one female collected by the writer in 
St. John’s Valley, Trinidad, B. W. I. (June 12, 1942, July 3, 1943).

Say, designated by Van Duzee, Check list of the Hemiptera of America north 
of Mexico, p. 79, 1916.) 
Vertex rather short, approximately one and a quarter times as wide 
across basal angles as long in middle, more or less excavated dorsally, 
lateral margins between eyes subparallel or slightly converging, dis- 
tally curving mesad, posterior margin shallowly but distinctly ex- 
cavated, median carina present in basal half; frons scarcely longer 
than wide at widest part, lateral margins expanding to below level 
of antennae, then curved in to suture, slightly elevated, a transverse 
carina at base, which together with convergent lateral carinae of 
vertex bounds a triangular areolet on each side, frons in profile 
slightly curved, median carina distinct, percurrent; clypeus not so 
wide as frons at widest part, tricarinate, slightly tumid near middle, 
about as long as frons; antennae small, second segment globose. Pro- 
notum short, less than half length of vertex, anterior margin convex, 
transverse across disk, posterior margin broadly excavate, disk tri- — 
carinate, lateral carinae diverging posteriorly, a series of five weakly 
bordered depressions on each side of disk, and a larger areolet between 
eye and tegula on each side; mesonotum tricarinate, lateral carinae 
diverging slightly posteriorly. Tegmina elongate, costal and com- 
missural margins subparallel, slightly broader beyond apex of clavus, 
Sc+R fork at or near middle, basad of apex of clavus, M with three
