154 University of California Puhlications. [Entomology 



Face and cheeks yellowish, often grayish directly beneath the 

 eyes. Palpi light yellow; all of the femora except the knees, 

 the lower part of the pleurae, and the abdomen with close 

 grayish pubescence. In most specimens a black or dark-brown 

 cloud extends from the lower part of the pleurte on each side 

 upward across the shoulders, thence backward diagonally across 

 the thorax, meeting at the center above, thus leaving a triangu- 

 lar light-brown spot on the pronotum. A reddish-brown vitta 

 crosses this triangular spot from the front backwards, dis- 

 appearing in the darker cloud behind. The dark color is 

 usually slightly dispersed or entirely wanting on the scutellum ; 

 occasionally it crosses the center of the thorax diagonally 

 or is otherwise irregular. Abdomen hoary like the femora, 

 with brownish spots irregularly arranged on the anterior part 

 of each segment, generally leaving the lateral border and a 

 median line above grayish. Tips of femora, upper part of 

 front tibiaB, middle of hind tibia and the tarsi, except their 

 tips, yellow ; lower part of front tibiae and their tarsi blackish. 

 Tips of all the tarsi slightly blackish. Wings uniformly a 

 trifle brownish; halteres pale yellow. Face falling off con- 

 siderably beneath the antenna for this genus, with a slight 

 median ridge above. Face narrow; entire body slender. Pat- 

 tern of thoracic macrochcetae and venation of wings normal. 

 Length, 3 to 3.25 mm. Middle and Southern California. 



Parydra aurata, n. sp., $ and $ . — Very similar to 

 Parydra Mtuherculata, but differs fundamentally in the absence 

 of the conical warts of the scutellum, also in the absence of 

 brownish dusting on the face, in the lighter color of the 

 antennae, and the possession of uniform golden pubescence. 

 Entire insect clothed with golden-yellow pubescence, under 

 which it is black, more or less shining, and sometimes with a 

 steel-blue reflection on the abdomen. Epistoma more densely 

 pubescence toward the oral margin ; antenna brown or brown- 

 ish yellow ; tibiae reddish yellow, sometimes distinctly brownish 

 in the center; tarsi reddish-yellow, last joint brown or black. 

 The characteristic bristle on each side of the face long and 

 slender; a distinct impression above and toward the center of 

 the face from this. Orbits and cheeks broad; clypeus very 

 prominent; epivstoma with two broad, very flat transverse 

 ridges crossing the center above the clypeus (these are some-
