base, the tip of the process bent outward; inner margin simple, devoid 
of lobes. 
Anal segment of female short, lateral angles not produced. Lateral 
styles simple, rather narrow, tapering bluntly to apex. 
Described from 15 males and 9 females collected by the writer in St. 
John’s Valley, Trinidad, B. W. I. (June 12, July 24, 26, 1942), resting 
‘on low bushes. Holotype male and allotype, U.S.N.M. No. 56692; 
paratypes in B.M.N.H. This species is distinguished by the shape of 
the anal segment of the male, of the genital styles, and of the aedeagus 
and by the dark color of the rostrum, legs, and abdomen. 
CEDUSA RUBRIVENTRIS, new species 
PLATE 10, FicUrEs 191-194 
Male: Length, 2.6 mm.; tegmen, 3.1 mm. Female: Length, 2.6 
mm.;tegmen,3.l1mm. Head, thorax, and tegmina as in C. cyanea. 
Head and thorax dark fuscous; sclerites of abdomen and genitalia 
sometimes testaceous or fuscous; subapical joint of rostrum pallid, 
apical joint piceous; legs pallid or testaceous; membrane of abdomen 
crimson red; tegmina smoky brown, a spot at base of stigma, a short 
transverse vein near apex of stigma, and a narrow line from apical 
fork of Se to apex of clavus hyaline; veins concolorous or slightly 
darker brown; wings hyaline, clouded fuscous, veins darker. In female 
first valvulae pallid or testaceous; insect in life powdered dusky blue. 
Anal segment of male tubular, elongate, 2.4 times longer than wide 
at base, in dorsal view narrowing distally but expanding just before 
apex; membranous portion forming an elongated triangle medially. 
Pygofer with lateral margins very slightly sinuate, devoid of a median 
process ventrally. Aedeagus basally a simple tube; distally on left side 
of flexible portion a broad spinose process, angularly bent in middle, 
directed anteriorly in repose; mesad of this process and about as long, 
a membranous tube, sclerotized along its right side, terminating in 
two short falcate processes, one being rather blunt, the other spinose; 
on right side of flexible portion of aedeagus a sinuate spine directed 
obliquely upward, and distad of it a narrow, curved, bladelike process 
expanding into a flat blunt lobe at apex. Genital styles large, in 
ventral view with a blunt lobe on inner margin near base, then ex- 
panding and abruptly tapering toward exterior margin, which is pro- 
duced at apex into a sharp point directed mesad. 
Anal segment of female short. First valvulae of ovipositor with 
| 
margins straight and almost parallel, bearing five spinose processes, — 
long and slightly diverging.
