Another specimen undoubtedly to be referred to the Mycetophilidse is 



figured in I'l. }>, Fig. 1_, but the fragment of the wing preserved is so 

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

 It seem>. however, to fall in the neighborhood of Anaclinia or Grnoriste, but 

 tin- 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 

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

 tion ot the second is aliout midway between that of the first and that of the 

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

 with cylindrical joints about twice as long as broad.

 specimen of this species. Mo~t ot' 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 oini-sion of the brachial vein, characteristic of this ^roiip

 downward and terminates on the radius above tin- middle cell, showing n<> 



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



wing. The middle cell is v than twice as long as broad. Tin- cubitus
