toward its outer end, rather more markedly concave near inner pro- 
jection, outer margin of style very slightly sinuate, inner margin with 
a slight projection beyond middle making the outline two unequal 
shallow concavities. 
Female similar in color to male. 
Described from one macropterous male and one macropterous 
female taken by the writer at St. Augustine, Trinidad, B. W. I. (July 
18, 1942), on Axvonopus compressus. 'Type male and allotype female, 
U.S.N.M. No. 56684. This species appears to be near nigra (Craw- 
ford), but differs in the aedeagus, having the orifice on the left side and 
a distinctly greater number of spines, as well as in the shape of the 
diaphragm and in the color of the antennae. 
DELPHACODES SPINIGERA, new species 
PLATE 9, Figures 111-114 
Male (macropterous) : Length, 2.4 mm.; tegmen, 3.0 mm. 
Width of vertex across base subequal to length or very slightly 
greater, base wider than apex, situated at middle of eyes; frons twice 
as long as wide, margins slightly arcuate; second segment of antennae 
scarcely twice length of first, first distinctly longer than wide. Pro- 
notum with lateral carinae diverging, curved, not reaching hind mar- 
gin. Hind basitarsus subequal to other two joints together; post- 
tibial spur two-thirds as long as basitarsus, thin, tectiform, toothed 
on hind margin. 
Stramineous, a narrow sinuate band on each side of middle line of 
frons and clypeus, a horizontal band near lower edge of lateral lobes 
of pronotum, a spot on pronotum between eye and tegula, and a narrow 
line on inner margin of tegulae fuscous; median carina of frons 
at basal fork, middle of vertex, pronotum and mesonotum pallid, 
bordered laterally tawny yellow on pronotum and mesonotum; teg- 
mina hyaline, yellowish, veins concolorous, six apical veins with a 
small fuscous spot at margin; wings hyaline, veins darker. 
Opening of pygofer about as long as wide, anal emargination large, 
anal angles not produced, lateral margins entire, very slightly curved, 
a minute point on each side level with ventral margin of diaphragm, 
a short setigerous toothlike process on posterior margin medioven- 
trally. Anal segment comparatively small, with a single stout median 
spine directed ventrad on apical margin. Penis compressed laterally, 
deflexed obliquely, lower margin almost straight, dorsal margin curved 
downward apically and tapering to join lower in a slender point, much 
broader than lower margin, so that penis is narrowly V-shaped in cross 
section; diaphragm rather narrow, with armature absent or incon- 
Spicuous. Genital styles narrow, rounded, with an asymmetrical knob
