tarsi, brown; a pair of rather large black or dark brown spots 

 on abdominal segments two to seven, last segment and the geni- 

 talia (pl.33, fig.6) also brown; mesonotum marked with three 

 darker yellow or brownish vittae, the middle one divided, hairs 

 of the antennae brownish; front tarsi destitute of long hairs, 

 middle and hind legs rather hairy, the fore metatarsus about 

 three fourths as long as its tibia, the fourth joint of the tarsi 

 more than one fourth as long as the first; wings hairy, whitish 

 hyaline, the veins yellowish; venation as figured; length 6.5 mm. 

 In one specimen, the one with the darker thoracic vittae, the 

 tips of the middle and hind femora and tibiae are darkened. 

 Axton, N. Y. A female specimen from New Jersey has dark 

 brown thoracic stripes and larger spots on abdomen. 



In the paper by Messrs MacGillivray and Houghton in the 

 Entomological News, January, 1903, this fly was identified as 

 Orthocladius par Coq., with the description of which it 

 agrees pretty well except for its hairy wings; the latter fact I 

 had overlooked.
