FULGOROIDEA OF TRINIDAD—FEN NAH 455 
basal ring directed posteriorly to apex of periandrium, then recurving, 
the spine on left side straight, sloping obliquely ventrad, with a line 
of minute denticles on its upper surface, the spine on right side loop- 
ing abruptly and sloping above periandrium to left side, then turning 
ventrad, minutely and somewhat sparsely corrugate near apex. Gen- 
ital styles triangular, expanding distally, obliquely truncate at apex, 
a rounded prominence on dorsal margin near base, a short curved 
spine at apex, a short triangular lobe projecting laterally near base. 
Anal segment of female rather long, narrow, margins as viewed 
laterally diverging gradually distally, apex obliquely truncate. 
Pregenital segment with a median ventral lobe. Ovipositor with 
first valvulae bearing four small and two large teeth dorsally with a 
broad deeply cleft lobe ventrally, second valvulae tubular narrowly 
sclerotized laterally, lateral styles elongate, rather narrow, dorsal mar- 
gin almost siraight, ventral margin curved, both narrowing distally to 
a constriction with a small triangular lobe distally. 
Described from eight males and seven females taken by the writer, 
one female at St. Augustine (Dec. 5, 1935), the remainder at Santa 
Margarita, Trinidad, B. W. I., on various dates in August and Sep- 
tember 1942, resting or feeding on bushes, including Croton sp. and 
bamboo. W. E. China has compared Trinidad material with the 
type.
