158 first Annual Report 
Lauxania pacifica n. sp. 
(Figure 90) 
A shining black fly, with front and face brownish red, base of 
antenne lighter. Abdomen gray pruinose, and quite thickly covered 
with reclinate bristles. Antenne three-jointed, third joint about four 
times as long as wide; dorsal arista is slender and bare, and about 
the length of the antenna. Halteres yellowish. Legs ight brown; a 
long spine on the under side of front femora, and a long spine on the 
mesopleura. There are four long scutellar bristles, and one sterno- 
pleural bristle. The lateral bristles of the abdomen are quite long. 
The length of the costal cell is about four times its width. The sub- 
costal cell reaches hardly half way to the tip of the wing, and the 
basal cells are very small. Wings yellowish hyaline. Length about 
4 mm. 
Collected at Laguna Beach by Prof. Baker. I have compared 
this with descriptions of variceps, longicornis, nigrimana, cinerea, 
and lutea. 
ORTALIDAE 
Chaetopsis aenea \Vd. 
Euxesta compta n. sp. 
(Figure 91) 
Light reddish brown, gray pruinose, the abdomen more gray. 
Differs widely from notata, nitidiventris, stigmatus, fascipennis, and 
abdominalis, which are either black or bluish in general coloration. 
Antenne red brown, the arista and third joint at base darker. The 
occiput is rather convex. Legs same color as body, the last four 
joints of the metatarsi darkened. Head quite large, front broad, 
bristles black. This species is perhaps closest to laticeps in color, 
but darker. Like laticeps, the body is thinly gray pruinose. The 
antenne are not so bare as in laticeps. Four bristles on the vertical 
triangle, two in front and two behind. Abdomen well clothed with 
bristles. Costal cell and end of wing smoky. Length 4 mm.; wing 
3.25 mm. 
Collected at Laguna Beach by Prof. Baker. 
TRYPETIDAE 
Eutreta sparsa Wied. 
Ensina humilis Lw. 
Euaresta abstersa Lw. 
Euaresta aequalis Lw. 
Urellia maverna Wk. 
All of the above Trypetids were frequent in the vegetation back
