Lauxania pacifica n. sp. 

 (Figure 90) 



A sliming black fly, with front arid face brownish red, base of 

 antenna? lighter. Abdomen gray pruinose, and quite thickly covered 

 with recliuate bristles. Antenna^ 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 light 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. AVings yellowish hyaline. Length about 

 4 mm. 



Collected at Laguua Beach by Prof. Baker. I have compared 

 this with descriptions of variceps, longicornis, nigrimana, ciiterea, 

 and lutca. 



ORTALIDAE 



Chaetopsis aenea \Yd. 



Euxesta compta n. sp. 



(Figure 111) 



Light reddish brown, gray pruinose, the abdomen more gray. 

 Differs widely from nutata, nitidiventris, stigmatus, fascipennis, and 

 ubdoiiiiiHilix, which are either black or bluish in general coloration. 

 Antennae red brown, the arista and third joint at base darker. Tin- 

 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 

 antenna? 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.
