152 MAINE AGRICULTURAL EXPERIMENT STATION. I9IO. 



Wheeler agree perfectly with Mr. Coquillett's description, to 

 v/hich I may add that the fore metatarsus is about ^ as long- 

 as the tibia ; empodium brush-like, shorter than the claws which 

 have 2 teeth each; hypopygium small (fig. 120), and anal vein 

 does not reach the margin (fig. 92). 



2. Dsiedzickia fuscipennis Coquillett. 

 1905. fuscipennis, Coquillett. Journ. N. Y. Ent. Soc. XIII. 6^. 



(Sciophila). 



Female. Length 6 mm. Distinguished by the dark brown 

 wings. Black, the femora, tibiae and bases of the tarsi and of 

 the halteres, yellow. Mesonotum polished, its hairs chiefly yel- 

 low, the marginal bristles mostly brown, hairs of abdomen 

 chiefly brown. First joint of front tarsi about 2-3 as long as 

 the tibiae. Wings dark brown, subcosta terminates in R^^ near 

 the middle of the small cell, petiole of cell M^ subequal in length 

 to the R-M crossvein, cubitus forks far before the R-M cross- 

 vein. Length 6 mm. Kaslo, British Columbia. 



In this species the cell R^ is much shorter than in D. pullata. 



3. Dsiedsickia n. sp. 

 There is an unnamed specimen from New Hampshire in the 

 Loew collection at Cambridge with hyaline wings in which the 

 petiole of the media is about twice as long as the R-M cross- 

 vein. A note in German apparently written by Loew mdicated 

 that he was uncertain of its generic position and therefore re- 

 frained from naming it. 



9. Genus Hadroneura Lundstrom. 

 Hadroneura, Lundstrom, Acta. Soc. Fauna, Flora Fenn. 29, 



1907. 

 Ocelli 3, middle one distinct. Wings (fig. 93) microscopi- 

 cally setulose ; costa slightly produced beyond the tip of R4+5 ; 

 the veins of the anterior parts of the wing unusually thickened ; 

 the cefl Ri elongated. The proboscis produced snout-like (fig. 

 61 in Pt. I). Abdomen 8 segmented. Distinguished from 

 Dsiedickia by the snout-like proboscis and somewhat heavier 

 wingf veins.
