1730 Mycetophlla fenestrata Coquillet, new species. 



Near /rifasciata, but differing as follows: No brown coloring 

 at apex of any coxa or femur, inner side of middle tibiae with a 

 single short bristle near the middle. Wings having the first brown 

 band not beginning at the costa, but at the first vein, the brown 

 spot behind the fifth vein very faint, the second band coalesces 

 with the third along the costa and again along the forks of the 

 fourth vein, enclosing an oval hyaline spot just below the third 

 vein; neither of these two bands pass beyond the lower fork of the 

 fourth vein, although the wing is faintlj^ bordered with gray from 

 the apex of this fork to a short distance beyond apex of lower fork 

 of fifth vein; the latter vein forks only a short distance beyond the 

 forking of the fourth, its two forks widely separated and not con- 

 verging toward their apices. Length 3 mm. A single specimen.

1731 Neoempheria pullata Coquillet, new species. 



Brown, the first two joints of antennae, humeri, genitalia and 

 legs, yellow, the latter changing to brownish toward apices of tarsi; 

 antennae over twice as long as the head and thorax, joints of 

 fiagellum very elongate, the third joint of attennae about five times 

 as long as wide; body opaque, the hairs and bristles black; bristles 

 of tibiae shorter than greatest diameter of the latter; wings hyaline, 

 pubescent, auxiliary vein terminates in the first slightly before 

 middle of marginal cell, this cell about three times as long as wide, 

 third vein strongly bowed forward, peduncle of second posterior 

 cell about five times as long as the small crossvein, fifth vein forks 

 at about one-fourth of distance from its base to the small crossvein. 

 Length 3.5 mm. A male specimen. Stanford University, Califor- 

 nia. Type No. 7667, U. S. National Museum. 



1732 Sciophila calcarata Coquillet, new species. 



Black, the extreme base of third joint of antennae, halteres, 

 genitalia largely, femora, tibiae and base of first joint of tarsi, 

 yellow; third joint of attennae nearly three times as long as 

 broad, the following joints longer than wide; body opaque, gray 

 pruinose, mesonotum marked with three black vittae, the middle 

 one divided medially by a gray line, hairs and bristles of thorax 

 black; middle coxae bearing at apex of front side a forwardly 

 directed, two-pointed spur which is almost half as long as the 

 coxae; bristles of tibiae shorter than the greatest diameter of the 

 latter; wings pubescent, hyaline, auxiliary vein terminates near 

 middle of marginal cell, the subcostal crossvein slightly before the 

 middle of this cell, the latter about one and one-half times as long
