The following data are given to amplify the original description: 
Ovipositor with lateral styles bearing 17 spines on apical margin in 
two rows, alternately arranged and directed mesad; second valvulae 
adpressed, with ventral surface slightly curved in profile, apex bluntly 
pointed, dorsal margin with a rounded eminence at base and a vertical 
sabot-shaped or clog-shaped lobe at middle, directed anteriorly and 
upward; first valvulae twisted at base, broad, tapering upward to a 
point at apex with two small teeth subapically on each margin, and a 
small rather isolated tooth basad of pair on dorsal margin, a thin 
semicrescentic lobe, with a thickened ridge attached at base of each 
valvula and adpressed to its inner face. 
Five males and eight females, mostly of the pale form of this species,. 
are to hand taken by the writer on Liberian coffee and mango at St. 
Augustine, Trinidad, B. W. 1. (July 15, Sept. 29, 1942). 
136. Tegmina narrowed distally, costal and apical margins sinuate. 
Tribe SELIZINI 
LOCRONA, new genus 
Vertex short, frons distinctly wider than long, lateral margins. 
elevated, strongly incurved below level of antennae, median carina. 
present in basal half, frontoclypeal suture impressed. Pronotum 
fully three times as long as vertex, smooth, devoid of carinae, anterior 
margin convex, posterior margin shallowly concave; mesonotum in- 
flated anteriorly, carinae obsolete. Tegmina with margins expand- 
ing distally, costal margin not ampliately rounded, apical angle 
strongly curved, apical margin truncate, sutural angle markedly pro- 
duced, rounded at tip, not acutely pointed, costal membrane much 
wider throughout than widest part of costal cell, Sc simple, joining. 
costa at middle of tegmen, R forking basad of this point, M forking 
at about same level, Cu, forking basad of M fork, base of R and M, 
and posterior half of clavus granulate, apical line of transverse veins. 
slightly irregular, distinct, subparallel to apical margin, subapical line 
fairly even, distinct and undulate, both lines meeting costa anteriorly,. 
subapical and apical areoles of about equal length, apical veins mainly 
forked. 
Anal segment of male with lower margin scarcely decurved, in 
dorsal view rounded at apex, shallowly channeled medially distad of 
anus, telson arising two-fifths from base. 
Anal segment of female broadly ovate, rather longer than broad,. 
apical margin roundly truncate, deflexed abruptly, with a short median 
channel distad of anus, telson arising at basal third. Ovipositor with: 
lateral styles stout with about 20 teeth in two rows inside apical. 
margin directed mesad.
