A NEW GENUS OF OPHIONEURINE TRICHO GRAMMATIDE. 199 
Stigmal vein elongate, a little longer than the marginal, the post- 
marginal very elongate, over twice the length of the stigmal. Club 
longer and wider than the funicle, 5 a cone, 2 and 3 subequal, 
1 largest, wider than long; pedicel and funicle 1 subequal, similar in 
shape, the pedicel over twice longer than wide at apex ; funicle 2a little 
longer than wide, 3 wider than long, 4 still wider, shorter than any club 
joint. Palpi very short. Marginal cilia of fore wing only a little 
longer than normal (not a seventh the greatest wing width). 
The male is similar, but the sculpture (scaliness) of the scutum 
and scutellem is not hidden by down; the lateral ocelli are still 
farther from the eyes, the mandibles are moderately, broadly truncate 
at apex, the seutum bears a delicate median ruga, the scutellum no 
median carina, the scape dilated (most widely at apex), the pedicel is 
gourd-shaped and short, funicle joints vase-shaped, 1 larger than the 
pedicel, also 2 and 3, 4 a little smaller, 5 twice wider than long, its 
stalk very short; club tapering, 5 longest, conical, 1 a little smaller 
than funicle 5, the others a little wider than long. 
Described from numerous pairs reared from hemipterous 
eggs, Port of Spain, British West Indies, December, 1914 
(F. W. Urich). From Trinidad. 
Types.—Catalogue No. 20117, U.S. National Museum, four

antenne and a fore wing.

MATIDA FROM JAVA. 
By A. A. GIravu.t. 
OPHIONEURINI. 
Lathromeromyta, n. g. 
Female.—Like Lathromeris, Foerster, but the abdomen is not 
conical and plainly longer than the thorax, but short and obliquely 
truncate as in Ufens, no longer than the thorax, and the marginal cilia 
of the fore wing are moderately long, the longest about a third of the 
greatest wing width or somewhat less. Also, the antennze bear two 
ring-joints. Mandibles tridentate. Marginal vein not much longer 
than the stigmal. Similar to Lathromeroidea, Girault, but lacking 
one club joint and the discal ciliation is less regular. 
Male.—Not known. 
Type.—The following species. 
1. Lathromeromyia perminuta, n. sp. Genotype. 
Female.— Length, 0°30 mm. 
Dusky black suffused with yellowish, the fore wings distinctly but 
not deeply infuscated from base out to end of stigmal vein and from
