tibiae and tarsi light yellowish brown with abundant yellow hairs. 

 Wings hyaline or nearly so, the veins light yellow; venation (PI. 

 XXVI, fig. 15) as in stigmatica 0. S., but the cross-vein m is present, 

 closing the cell 1st M^. 



Abdomen brownish yellow. 



Holotype, 9 , Scotia, CaL, May 20, 1903 (H. S. Barber). 



This differs from the described American forms, stigmatica Osten 

 Sacken and nigrolineata Enderlein by its closed cell 1st M^ and the 

 uniform pale yellow coloration.

This curious fly was described from a single female taken at 

 PermiHarsukfiord, 01°, 30' N. L., Greenland. It seems to me that 

 t-he generic reference as given above is more nearly correct. The 

 €ross-vein r is shown in Dr. Lundbeck 's figure and it is indicated in 

 the material before me; it is probable that this species is an inter- 

 mediate form in the Eriopterine series. The following material was 

 studied: One female, Signuia, Baffin Land, August 2, 1897 (Schti- 

 chert and White). Several of both sexes, Kokanee Mt., Brit. Col., 

 alt. 8,000 feet, August 11, 1903 (R. P. Currie). 



I am greatly indebted to Dr. Lundbeck for a copy of the descrip- 

 tion and figure of this interesting fly.
