FULGOROIDEA OF TRINIDAD—FEN NAH 427 
half as long as anal segment. Pygofer long, anal emargination wide 
and rather deep, lateral margins produced caudad to form a lobe shal- 
lowly indented at apex, and about two-thirds as long as genital 
styles; ventral hind margin sinuate, devoid of medioventral process. 
Aedeagus comprising a narrow tube with a very long tubular flagellar 
appendage at apex, this appendage being widely curved through a 
complete circle dorsad; a small flat pointed lobe on its inner margin 
halfway from base, a very long thin filament arising on inner margin 
toward apex, the flagellar appendage itself tapering to a short sharply 
deflexed point. Genital styles broad at base, slightly diverging to 
their midpoints, then angularly converging almost to meet at apex; 
outer margin with sides almost straight, angularly bent at middle, 
inner margin straight for one-quarter from base, then deeply concave, 
becoming slightly convex before apex, so that the two styles enclose a 
heart-shaped cavity; apex of each style rounded into a blunt point. 
Described from one male specimen collected in Trinidad, B. W. L., 
by F. W. Urich (1920). This species differs from stigmata Crawford 
in size, in the shape of the genital styles, aedeagus, and anal segment, 
and in the color pattern. Holotype, U.S.N.M. No. 56679. 
Genus TETRASTEIRA Muir 
Tetrasteira Muir, Bull. Hawaiian Sugar Planters’ Exp. Stat., ent. ser., No. 18, 
pt. 1, p. 4, 1926. (Genotype, T. minuta Muir, ibid.) 
Head narrower than pronotum; vertex wider than long, with a V- 
shaped transverse carina dividing frons from vertex; frons longer 
than broad, median carina simple; antennae terete, small. Pronotum 
with lateral carinae reaching hind margin, median carina feeble; mes- 
onotum with four carinae, inner pair not reaching hind margin, outer 
pair attaining it. Legs comparatively short, tibial spur awl-shaped. 
Ovipositor complete.

PLATE 8, FIGURES 75-84 
Male: Length, 1.9 mm.; tegmen, 2.0 mm. 
Vertex very short and wide, with a carina in the shape of a wide 
inverted V; frons 1.6 times longer than broad, widest in apical half. 
Pronotum with median carina strongly present, mesonotum with four 
carinae, both pairs distinctly reaching hind margin. Hind tibiae with 
two spines. Tegmina with a strong fold on costal margin at stigma. 
Wings emarginate at suture. 
Dark brown, lighter over tegulae, base of tegmina, and a small 
triangular spot at costal fold; veins dark, except the cross veins at
