the last joint, oval aud about the size of the basal joint; the tips of the antonn®, in our unique specimen, are
broken oft' bej-ond the twenty-second joint : they are black and slender ; the abdomen is of moderate length ; the
wing-s are large and hyaline, with an oval spot at the tip of the wing within the fourth submarginal cell, and
a smaller round one in the middle of the outer middle cell; the fore wing on the right side has a small abnormal
spur running into the first submarginal cell, which is wanting in the left fore wing; the hind pair of tibia?
(Hg. 11./) have two apical and two middle spurs, but the middle tibia? have onl_y one middle spur; the claws ol'
the tarsi have a broad basal tooth.

This is a shorter and more compact species than the European ones. The antenniB are very short and 12-
jointed (fig. 10a) ; the second recurrent vein of the fore -nings forms a continuous line with the vein between
the second and third submarginal cell; the mandibles are marked with a large white spot in front; tlie
breadth of the thorax at the base of the fore wings is nearly equal to one-third of the length of the thorax
and abdomen, and the length of the fore wings is equal to that of the thorax and three-fourths of the abdomen.
The vein between the two marginal cells is received by the front of the second submarginal cell a short distance
before its extremity, and the vein between the second and third submarginal cells is continuous with the second
recurrent vein.

Smaller and considerably more slender than X orientaKs Westw. The antenn® are longer, more slender, with
more joints ; the apical half white; the crown of the head behind the eyes is polished; face in front of the ocelli,
longitudinally striated; face and sides of the head behind the eyes varied with white. The small transverse postscutellum
is white, as are two curs-ed oblique marks on the following bilobed segment. The stihapical joint of the abdomen
bils a white fascia, interrupted in the middle, and the apical joint is white. The vein between the two marginal cells is
oblique, so that it extends into the third submarginal cell on its fore edge, whilst its hind edge receives the second recurrent
vein at one-tlurd of its length from its base. The second submarginal cell is shorter than in X . o r i e n l a l i s , so that
the vein which closes its apex is nearer the base of the wing than the oblique vein between the two marginal cells and tlie
second recurrent vein.
