136 MAINE AGRICULTURAL EXPERIMENT STATION. I9IO. 



Sciophila fasciata Say (12), Sciophila popocatepetU Bell. 

 (14), and Sciophila (Lasiosoma) hirta Meigen (13) are not 

 included in the above table. The two former may not even 

 belong to this genus ; the latter, reported from Greenland, may 

 be distinguished from S. pallipes by its wholly black antenna 

 and scape. Sciophila grisea Walker may be a Polylepta, though 

 as likely may be a synonym of 5". pallipes Say. 6^. mirandula 

 Cockerell is a fossil species from Colorado. 



I. Sciophila quadratula Loew. 



1869. quadratula, Loew, Berl. Ent. Zeitschr. XIII. 141 



(Lasiosoma). 



Female. Length '3 mm. ; wing 2.8 mm. Luteous, clothed 

 with pale pile. Head and flagella of antennas fuscous black, 

 scape reddish, palpi pale yellowish. Mesonotum not vittate, 

 metathorax more or less fuscous. Abdomen fuscous black, the 

 posterior margin of each segment more or less pale, the apex 

 of abdomen luteous. Legs and coxae yellowish, the tarsi except 

 the base, fuscous, the more slender veins paler ; cell R^ small, 

 quadrate, the subcostal crossvein placed at the middle ; the fur- 

 cation of the media about opposite the apex of the subcosta. 

 Halteres yellowish. Recorded from Maine. After examining 

 the type I may add that the wing is over three times as long as 

 the fore tibia, the distance from the humeral crossvein to the 

 subcostal crossvein is about 2-3 greater than from the latter to 

 the tip of the subcosta, and that the cubitus forks proximad of 

 the tip of the subcosta. 



2. Sciophila glabana n. sp. 

 Male. Length 5.5 mm. ; wing 4 mm. Head reddish, infus- 

 cated, especially around the ocelli ; face, palpi, and scape of the 

 antenna yellow, flagellum fuscous, intermediate joints over 1.5 

 times as long as wide, ocelli in a transverse line. Thorax yel- 

 low, with a minute brown spot at the root of the wing; setae 

 yellow. Abdominal segments brown with both the anterior 

 and posterior margins yellow; hypopygium shining yellow, the 

 blunt spines of the inferior forceps fuscous; terminal flap of 

 dorsal plate provided with 6 strong marginal and several distal 

 setae (fig. 122) ; superior forceps slender, somewhat curved and 

 each limb with a strong terminal seta ; the inferior forceps short, 

 ovate, the apex with a number of stout, blunt but short spines
