Tune, 1905.] COQUILLETT : DlPTERA FROM NORTH AMERICA. 65 



just beyond apex of third vein, the latter reaches two thirds length of wing, 

 apex of first vein near four fifths length of the third, costal vein considerably 

 widened near the apex. Length I mm tinicolor.* 



Tanypus miripes, new species. 



Near hirtipennis and pilosellus but in these the fourth joint of the tarsi is slender 

 and at least two thirds as long as the third, while the fifth is only slightly smaller 

 than the fourth. Yellow, the antennas, mouth parts, three vittre on the mesonotum, 

 the metanotum, and the front ends of the segments of the abdomen, brown. Plu- 

 mosity of antennae brown, the apices yellow. Body opaque, grayish, pruinose, the 

 hairs yellowish white. Tarsi with rather long pubescence but not distinctly bearded, 

 the front and hind ones slender and elongated, the middle ones rather robust, the 

 last three joints rather short, the fourth about one half as long as the third, the fifth 

 unusually small, wings densely haired, hyaline, a brown cloud on the small cross- 

 vein, in certain lights an indistinct brownish cloud in outer half of anal cell and a . 

 crossband of the same color near three-fourths length of wing ; first vein forked a 

 short distance before the apex, crossvein at apex of second basal cell situated slightly 

 beyond base of upper branch of fifth vein. Length 4.5 mm. 



Eureka, Cal. A male specimen collected May 22 by Mr. H. S. 

 Barber. Type No. 8371, U. S. National Museum. 



Tanypus sinuosus, new species. 



NearjoAnsoni and bifasciatus, but differing from both by the very sinuous second 

 brown crossband of the wings. Yellow, varied with whitish, the legs wholly whitish, 

 the mouth parts, and in the male the antennse except the first joint, a spot in front of 

 each wing, a pair of spots in front of the scutellum, the front ends of the abdominal 

 segments and nearly the whole of the last two segments, brown, in the female with 

 three brown vittre on the mesonotum, the median one divided in the middle by a yel- 

 low line. Plumosity of antenna? gray basally and yellow distally, appearing wholly 

 yellow in certain lights. Body opaque, hairs yellow and with several brown ones on 

 the abdomen of the male. Tarsi slender, fourth joint much longer than the fifth, 

 front tarsi of male bearded with rather long hairs. Wings densely covered with 

 hairs, hyaline, a faint brownish crossband passes over the crossveins and is expanded 

 in the anal cell ; a broader brownish crossband begins on the costa just beyond the 

 forking of the first vein and extends almost to the upper branch of the fifth vein, then 

 turns towards the base of the wing for a short distance and then again changes its 

 course and reaches the hind margin of the wing just before the apex of the lower 

 fork of the fifth vein ; the proximal edge of the upper portion of this crossband is 

 nearly on a line with the distal edge of the lower portion ; an indistinct brownish 

 cloud on apex of fourth vein and of upper branch of the fifth ; first vein forked 

 toward its apex, crossvein at apex of second basal cell slightly beyond the forking of 

 the fifth vein. Length 2 to 3 mm.
