34 MYCETOPHILIDjE. 



Of the last division there is but one species, which has as yet 

 been found only in Denmark. It partly agrees with Azana in the 

 structure of its wing-veins. The first division is also unknown 

 in Britain. It comprises two European and one Greenland species. 



1. dubia, Stseg. D. D. 235. 3 (1840); Zett. Cinereo-nigra, alia 

 subcinereis, halteribus pedibusque testaceis, tarsis nigris. Long. 3-3i ; 

 alar. 5-6 lin. 



Black. Antennae slender, a little longer than the thorax. Head and 

 thorax slightly covered with grey tomentum. Wings very slightly 

 greyish ; veinlets of the pra?brachial areolet forming a hardly acute 

 angle, the hind one almost four times the length of the fore one, and 

 shorter than the subapical vein before its fork ; fork of the subanal 

 vein nearer than the fork of the subapical to the base of the wing ; 

 anal vein extending nearly to the fork of the subanal. Halteres tes- 

 taceous. Abdomen long. Legs testaceous, long, slender ; tibia? darker 

 than the femora ; tarsi black ; hind tibia? with rather long spurs and 

 with short spines ; fore tibia? longer than the fore metatarsi.

Ferruginous. Vertex and disc of the thorax cinereous. Palpi tawny. 

 Antennas black, hardly longer than the thorax. Wings slightly grey- 

 ish; radial and cubital veins distinct; subapical and subanal veins se- 

 condary ; veinlets of the prrcbrachial areolet forming an obtuse angle, 

 the hind one twice the length of the fore one, and hardly one-fifth of 

 the length of the subapical vein before its fork ; radial vein undulating ; 

 fork of the subanal vein very much nearer than the fork of the subapical 

 to the base of the wing ; anal vein extending far beyond the fork of the 

 subanal, but not to the border. Halteres testaceous. Abdomen long, 

 slender ; hind borders of the segments testaceous. Legs long, slender ; 

 tarsi blackish ; hind tibiae with very short spines and moderately long 

 spurs ; fore tibia? much shorter than the fore metatarsi.

 maculis dnabus anticis fulvis, alis sublimpidis, femoribus basi nigris, 

 tibiis fulvis, tarsis fuscis. Long. 2f ; alar. 5 lin. 



Black. Palpi testaceous. Antenna stout, much longer than the 

 thorax. Thorax with a slight tawny spot on each side in front. Wings 

 nearly limpid ; veinlets of the prrcbrachial areolet forming an obtuse 

 angle, the hind one a little more than twice the length of the fore one, 

 and a little longer than the subapical vein before its fork ; fork of the 

 subanal vein a little nearer than the fork of the subapical to the base 

 of the wing ; anal vein extending much beyond the fork of the subanal.
