FULGOROIDEA OF TRINIDAD—FENNAH AT1 
testaceous, fuscous laterally, rostrum fuscous, genae testaceous, sides 
above eyes fuscous; pronotum fuscous with a row of four ochraceous 
spots behind eyes and a few such spots on pronotum below eyes, 
mesonotum dark fuscous, a paler line near tegulae, a small ochraceous 
spot at base of lateral carinae and at tip of scutellum; legs fuscous; 
abdomen dark fuscous dorsally, pale ventrally, membrane pallid, geni- 
talia fuscous; tegmina fuscous, darker on costal area and in a broad 
band across clavus just beyond middle, corium sprinkled with ochra- 
ceous spots, veins marked with spots throughout, a very pale rounded 
spot before stigma, membrane broadly and irregularly clouded with 
dark fuscous between stigma and @pex of clavus, with sparse irregular 
ochraceous markings, subapical line, apical margin, and apical third 
of claval cells hyaline or pallid, a dark fuscous band traversing middle 
of apical cells parallel to margin, a darker fuscous spot in one cell 
at anterior apical angle; wings fuscous, veins dark except M-Cu, 
eross vein, and fork of Cu,, which are hyaline. 
Anal segment of female short, ringlike, telson thick, flattened, 
broadly semiovately rounded. Lateral styles of ovipositor broad, 
subquadrate, membranous part of apical margin narrow, with its 
basal edge subparallel to margin, a pointed membranous filament 
dorsally at apex; first valvulae strongly curved downward distally, 
with a small tooth dorsally at apical third, and two large sickle- 
shaped teeth subapically. Pregenital segment with posterior margin 
straight. 
Described from one female collected by F. W. Urich, Verdant Vale, 
Trinidad, B. W. I. (January 1912). ‘This species is distinctly smaller 
_ than the others of the genus; it differs from marmoratum Metcalf in 
the proportions of the vertex and from both marmoratum and fuscum 
Metcalf in details of tegminal venation and in color, occupying in 
the latter respect an intermecliate position between Metcalf’s species. 
The ovipositor is of the characteristically achilid pattern. Type, 
U.S.N.M. No. 56700. 
9b. Vertex not very short, not more than three times as broad as long, anterior 
margin more or less convex.

Plectoderes Spinota, Ann. Soc. Ent. France, ser. 1, vol. 8, p. 328, 1839. (Geno- 
type, Flata collaris Fabricius. ) 
Vertex between basal angles three times length in middle, lateral 
margins slightly converging distally, anterior margin carinate, dis- 
tinctly convex, posterior margin broadly excavated, vertex projecting 
in front of eyes for half its length, its base on middle line anterior to
