Abdomen rather thickly haired, dark brown, genitalia fuscous yel- 

 lowish. 



Wings hyaline, subcosta uniting with the margin near the basal half 

 and the cross-vein nearly parallel with costa, the third vein stout, 

 strongly curved distally and joining the margin well beyond the apex. 

 i ; ' urth vein simple, weaker than the third, obsolescent basally. Fifth 

 vein a little stouter than the third, simple, obsolescent basally ; sixth 

 vein simple, moderately stout, strongly curved distally and uniting 

 with the posterior margin a little before the basal half. Halteres 

 mostly pale yellowish. 



Legs nearly uniform dark brown, the femoro-tibial and the tibio- 

 tarsal articulations narrowly yellowish. Claws moderately long, stout, 

 curved, unidentate, the tooth with a series 'of minute denticulations 

 basally. The pulvilli about half the length of the claws. 



Genitalia : basal clasp segment moderately long, stout ; terminal 

 clasp segment long, tapering triangular when seen from the dorsum, 

 the length being about 2 l / 2 times the greatest width. The apex slightly- 

 curved and obtuse, and not noticeably chitinized. Dorsal plate short, 

 broad, tapering to a broadly, slightly emarginate. somewhat lobed 

 posterior margin. Ventral plate divided, the lobes broadly quadran-

Porricondyla consobrina n. sp. 



This insect was collected August 3, 1918, at Gull Lake, near 

 Muskoka, Ontario, Canada, by H. S. Parish. The species is 

 very close to P. iirccnalis Felt, from which it is most easily 

 separated by its somewhat larger size, paler color, reduced 

 chitinization of the abdominal segments and the distinctly 

 longer tips of the lance-like harpes. 



$. Length 2.5 mm. Antennae a little longer than the body, thickly 

 haired, fuscous, the stems whitish transparent, 16 segments, the fifth 

 with a stem two and one-half times the length of the basal enlarge- 

 ment, which latter has a length one-half greater than its diameter. 

 Terminal segment with a length four times its diameter and tapering 

 gradually and nearly uniformly to an acute apex. Palpi: first seg- 

 ment with a length about four times its diameter, the second about as 

 long as the first, a little stouter, the third one-half longer than the 

 second, more slender, and the fourth one-half longer than the third. 



Thorax and bodv a nearly uniform pale yellowish. Halteres yel- 

 lowish transparent.
