A NEW BLEPYRUS
By ©. Ts BRUES

Blepyrus tachigalie sp. nov.

Female. Length 1. mm. Head metallic green, thorax
black with an eneous cast, abdomen bronzed black; antennze
vellow and black, the scape and funicle yellow, darker on the
scape basally, the pedicel and club black; coxe black, femora
black with brown tips, tibize brownish yellow with a black
streak at base, tarsi pale, with the last joint dark. Wings
deeply infuscated basally, hyaline on apical half. Front one-
fourth the width of the head at middle, broader above and
below, with large punctures forming about four vertical rows;
malar furrow shallow and not very distinct; cheeks finely, ver-
tically aciculated, eyes with short pubescence. Antenne inserted
close to the mouth, the scape reaching barely halfway to the
vertex, excavated and distinctly, although not broadly, produced
below; pedicel triangular, longer than thick and half as long
as the funicle; funicle joints about equal in length, the apical
joint more than twice as broad as the basal one; club enlarged,
flattened and obliquely truncate at apex, as long as the pedicel
and funicle together. Thorax, including scutellum, highly
convex when seen in profile, the mesonotum nearly as long as
the scutellum, the surface of both shining, minutely punctulate
and finely hairy; axillary suture apparently obsolete; scutellum
very long, the side margins straight till near the apex, which
is therefore rather sharply rounded. Abdomen very short,
concave above, with long, scattered hairs at the sides. Legs
stout, the spur of middle tibia strong, as long as the first tarsal
joint, the tarsal spinules strong on all four basal joints. Mar-
ginal vein short, not over twice as long as thick; stigmal vein
long, postmarginal slightly shorter, their angle of separation
about 100 deg.; wing cilia short, those on the costa longer.

Type and paratype bred from Pseudococcus bromelix
Bouché, occurring in cavities in the petioles of Tachigalia sp.
at Kartabo, British Guiana.

This species agrees well with Howard’s original generic
diagnosis’ except that the antennal scape is slightly enlarged
below as in certain species of Bothriothorax (e. g., B. minor
Silvestri). The color of the body, appendages and wings will -
distinguish the present form.
