FULGOROIDEA OF TRINIDAD—FENNAH 437 
Anal segment obliquely defiexed, produced below anal opening into 
a quadrate plate with lateral angles produced, a pair of sclerotized 
sinuate rodlike processes arising near middle of hind margin directed 
posteriorly. Ovipositor with lateral styles moderately broad, taper- 
ing distally to a blunt point, not attaining tip of processes of anal 
segment, first valvulae with five or six oblique spines on dorsal margin 
distally. Subgenital plate in ventral view with hind margin curved 
backward into a broad median plate, approximately hexagonal in out- 
line, with a narrow triangular process directed caudad arising on hind 
margin at middle. 
Described from three female specimens collected in Trinidad, B. W. 
I., as follows: F. W. Urich, two specimens, one accompanied with a 
locality label “Maraval” (1916); D. Farrell, one specimen (1920). 
‘These specimens were taken by the writer from the collection of the 
former Imperial Department of Agriculture. This species is dis- 
tinguished by the proportions of the apical cells of M in the tegmina, 
by the shape of the posterior border of the subgenital plate, and by the 
color pattern of tegmina and wings. Type, U.S.N.M. No. 56686. 
DERBE BOLETOPHILA, new species 
PLATE 9, FIGuRES 124-128 
Male: Length, 6.3 mm.; tegmen, 13.0 mm. 
Tegmina with posterior sector of M with six branches reaching 
margin, the cells posterior to the third to sixth of these branches ten 
times as long as wide. 
Head, thorax, legs, and genitalia pale stramineous; posterior half 
of pronotum, metanotum, and abdomen pallid, almost white; abdom- 
inal sclerites narrowly bordered red; tegmina and wings vitreous, an- 
terior margin of tegmina narrowly lined red. Insect in life is very 
pale. 
Anal segment long, rather flattened dorsoventrally, folded and de- 
flexed at tip. Pygofer with lateral margins sinuate, ventral margin 
straight, medioventral process in form of a small lobe not quite semi- 
circular. Aedeagus a simple sclerotized tube in basal portion; re- 
flected apical portion viewed from left side trapezoidal with a mem- 
branous tube attached apically; three spines on left side of reflected 
limb, one anteroventrally near attachment, two near distal part of line 
of attachment, one spine long, decurved at tip, the other straight, two- 
_ thirds as long as preceding; on right side of aedeagus a long spine basad 
of reflected part directed obliquely upward, laterad of reflected part 
a broad lamina narrowing to a twisted bladelike process directed an- 
teriorly, two spines of equal length on dorsal side of reflected part 
near its point of attachment. Genital styles narrow at base, widening 
to just beyond middle then narrowing to a point at apex, this being
