the last joint oval and about the size of the basal joint; the tips of the antennz, in our unique specimen, are 
broken off beyond the twenty-second joint: they are black and slender; the abdomen is of moderate length ; the 
wings 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 tibize 
(fig. 11) have two apical and two middle spurs, but the middle tibie have only one middle spur; the claws of 
the tarsi have a broad basal tooth,

This is a shorter and more compact species than the European ones. The antenne are very short and 12- 
jointed (fig. 10a); the second recurrent vein of the fore wings 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; the 
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.

1 LY. leviceps. Nigra, albo-maculata, tibiis tarsisque basi albis, alis hyalinis iridescentibus. 
Long. corp. lin. 54; expans. alar. antic. lin. 8. 
Smaller and considerably more slender than Y. orientalis Westw. The antenne 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 post- 
scutellum is white, as are two curved oblique marks on the following bilobed segment. The subapical joint of the abdomen 
has a white fascia, interrupted in the middle, and the apical joint is white. The vein between the two marginal cells is 
obliqne, so that it extends into the third submarginal cell on its fore edge, whilst its hind edge receives the second recur- 
rent vein at one-third of its length from its base. The second submarginal cell is shorter than in Y. orientalis, 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 the 
second recurrent vein.
