long and 0.14""" broad. The wings are less than three times as long as 

 broad, and very regularly rounded ; the costal vein (especially on the front 

 wing) is thickened and covered with closely clustered, minute, spinous 

 hairs, and similar black hairs follow in a single row the base of the radial 

 and cubital veins. The wings are very dark, with large white or pale spots, 

 of which three are most conspicuous, occurring similarly on all the wings. 

 One, of a subquadrate or subovate form, broader than long, lies scarcely 

 beyond the middle of the wing, extending from the costa to the upper branch 

 of the cubital vein ; another, nearly as large and similar in form, is subapi- 

 cal, extending from just beyond tlie last fork of the upper branch of the 

 radial vein to or just beyond the upper fork of the lowest branch of the 

 same ; a third, smaller, transversely oval spot, lies next the inner border, 

 below and a little outside the first mentioned, being situated just beneath 

 the forking of the upper branch of the cubital vein ; there is also more or 

 less pale cloudiness about the basal half of the wing, and white flecks may 

 be seen at various points near the tip, especially below the subapical spot. 

 The abdomen resembles somewhat that of the remarkable Panorpanemato- 

 gaster M'Lachl. from Java, where it is greatly elongated, and possesses a 

 curious appendage to the third joint. In the fossil species, the first three 

 joints, taken together, taper gradually and slightly, and the third mny have 

 had a peculiar appendage at its tip, as the edge is not entire, but appears 

 deeply excavated in the middle, possibly due, however, to its imperfect 

 preservation ; the basal half of the fourth joint partakes of the tapering of 

 the abdomen, but its apical half is swollen and its hind margin broadly 

 rounded ; the fifth and sixth joints are a little longer and much slenderer 

 than the preceding, subequal and cylindrical ; the fifth depressed on either 

 side at the base by a pair of fovea3 ; the seventh again much smaller, linear 

 or not half the width of the sixth, increasing slightly in size apically ; the 

 eighth as large at base as the seventh at tip, enlarging slightly apically, and 

 all the joints together half as long again as the wings. Most unfortunately, 

 the apical joint is lost. The specimen is evidently a male.
