 the same features in 8. arcuata, excepting that the second longitudinal vein 

 terminates a little higher up.

Another specimen undoubtedly to be referred to the Mycetophilidaj is 

 figured in PI. 9, Fig. 12, but the fragment of the wing preserved is so 

 obscured by the overlying legs that a nearer determination is impossible. 

 It seems, however, to fall in the neighborhood of Anaclinia or Grnoriste, but 

 the weaker parts of the neuration and the origin of the veins are so obscure 

 that no closer determination can be made. The first longitudinal vein is 

 longer than usual, reaching to beyond the tip of the wing, and the termina- 

 tion of the second is about midway between that of the first and that of the 

 third. The antenn;e are moderately slender, about as long as the thorax 

 with cylindrical joints about twice as long as broad.

Some fragments of legs and one wing are all that remain of the single 

 specimen of this species. Most of the neuration of the wing, and especially 

 of the more important portions, can be made out, but an error occurs in the 

 drawing, in the omission of the brachial vein, characteristic of this group 

 of Mycetophilidaj. The species is peculiar in that the auxiliary vein bends 

 downward and terminates on the radius above the middle cell, showing no 

 branch to the costa. The radius terminates far out toward the tip of the 

 wing. The middle cell is more than twice as long as broad. The cubitus 

 terminates at the extreme wing-tip; the stalk of the upper discoidal vein is
