halteres. From this latter it may be distinguished by the posi- 

 tion of the subcostal cross- vein and from the former by the 

 body being more yellow, wings narrower and in having three 

 brown stripes on the thorax. In halter ata the pleura of the 

 hypopygium are quite as large as the lobes that are appended 

 to them, while in particeps they are much smaller than the lobes. 



Dicranomyia adjecta n. sp. — Yellowish brown; head, rostrum, palpi and 

 antennae darker brown; first three joints of the flagellum rather globu- 

 lar, others more cylindrical, all distinctly pedicellate ; thorax yellowish 



brown; dorsal stripes faintly or not 

 at all indicated; pleura yellowish, 

 with a broad, brown band from the 

 collare to the base of the halteres; 

 halteres long, infuscated ; coxae 

 yellowish; legs tawny; extreme tip of the femora lighter; tarsi darker; 

 abdomen brown, lighter below; basal lobes of hypopygium dark brown, 

 lamella lighter brown; ovipositor ferruginous, blackish at the base; lower 

 valves straight, rather heavy; upper valves more slender, slightly arcu- 

 ated; wings hyaline; veins and stigma brown; auxiliary vein reaching a 

 little beyond the origin of the praefurca, subcostal cross-vein at its tip; 

 first longitudinal vein fading out a little beyond the marginal cross-vein 

 before reaching the margin of the wing: discal cell closed. Length 7 

 mm., wing 9 mm. 



Hab. — Stanford University, Cal. Two males, two females. 

 May at once be distinguished from halterata, which it re- 

 sembles somewhat, by the position of the subcostal cross-vein. 



Dicranomsia cervina, n. sp. — Brown; head brownish, darker above; ros- 

 trum yellow; palpi and antennae brown; thorax brownish, the dorsum 

 with three darker brown stripes, the median one extending over the col- 

 lare; scutullem and metanotum 

 grayish brown; legs tawny, tarsi 

 and the tips of the femora and 

 tibise darker ; halteres whitish, 

 infuscated toward the tips, knobs 

 brown; abdomen brown, much lighter below; hypopygium yellowish 

 brown; tergum but little swollen, pleura about as large as lobes, basal 

 half yellowish, distal half brownish; ventral style strongly recurved at 

 the tip; wings with a very light brown tinge; stigma pale, indistinct; tip 

 of the auxiliary vein beyond the origin of the praefurca; distance of the 

 subcostal cross-vein from the tip of the auxiliary vein equal to one-half 

 the length of the praefurca; discal cell closed. Length 7 mm., wing 

 8 mm. 



Hab. — Stanford University, Cal. One male.
