504 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 96 
Vertex short, 2.5 times as broad as long, anterior margin somewhat 
angularly produced, apex rounded; frons wider than long (1.2:1), 
inflated medially at base, fiat near suture, median carina feebly pres- 
ent, lateral carinae obsolete on disk. : 
Pale green; costa pallid, a series of minute linear markings inside 
apical margin of tegmen fuscous, protarsi and mesotarsi pale fuscous, 
protibiae distally pale fuscous speckled with white. 
Anal segment of male long, narrow, tubular, postanal portion 
slightly deflexed, shorter than preanal portion (1:1.3), a shght protu- 
berance ventrally below anal opening. Pygofer with posterior lateral 
margins slightly convex, ventral margin very slightly concave, devoid 
of a median process. Aedeagus tubular, with a membranous flange, 
slightly incurved, arising on dorsal margin in distal half and taper- 
ing to apex, a somewhat folded eminence on each side ventrally at 
middle from which arises a bladelike spine directed in its basal half 
mesad and posteriorly, and bent outward in its distal half; in middle 
line ventrally a single process in form of a broad short spine directed 
caudad. Anal segment of female elongate, produced beyond anal 
opening in-a flat and shallowly grooved lamina scarcely notched at 
apex. Ovipositor with lateral styles large, bluntly angularly pointed, 
dorsal margin concave, ventral margin curved through less than a 
quarter of a circle, greatest width 1.6 times length; first valvulae with 
a double row of four teeth on dorsal margin and five teeth crowded 
near apex. Pregenital sternite with hind margin sinuate, slightly 
produced caudad on each side of middle line with a rather broad 
shallow emargination medially. 
Egg ovoid, with a chorionic process at one pole tightly coiled, when 
extended consisting of a filament forking into two rami distally; 
length, 1.1 mm., width, 0.5 mm. 
Described from four males and six females collected at St. Augus- 
tine, Trinidad, B. W. I., by the writer (May 18, Aug. 10, 25, Oct. 2, 
1942) on Hrbiscus, coffee, and cacao, and three females collected by 
Dr. EK. McC. Callan (May 18, 1939, Feb. 8, 19483) on cacao in the same 
locality. Holotype male and allotype, U.S.N.M. No. 56712; para- 
type in B.M.N.H. This species is distinguished by the tumid frons, 
the curved anterior margin of the vertex, the shape of the anal seg- 
ment of the male, and of the aedeagus, by the broad excavation on 
the hind margin of the pregenital sternite, and the shape of the 
lateral styles, and by the fuscous color of the distal half of the protibiae. 
It differs from A. decens Stal, to which it appears most nearly allied, 
in the more rounded apical angle of the tegmina.
