74 THE CANADIAN ENTOMOLOGIST. 



brown, the following spots hyaline : four in costal cell (none between 

 apices of auxiliary and first veins); three in marginal cell, situated between 

 apices of first and second veins, three in sub-marginal cell of which one 

 is contiguous to the middle spot in marginal cell and two are between 

 apices of second and third veins ; three in first posterior cell, the one in 

 the apex reaching the wing margin, three in second posterior cell, all of 

 them contiguous with the wing margin, four in third posterior [cell, of 

 which three are along the wing margin ; three in axillary cell, two in the 

 second basal, two in first basal, of which one is sub-basal and the other 

 near its apex, also one in discal cell near its apex : first vein bristly, the 

 others bare ; length, nearly 4 mm. Southern California. A single female, 

 in May. 



The wings closely resemble Figure 23, Plate X., of Loew's Monograph, 

 but there is only one hyaline spot in the discal cell, four in the third 

 posterior, etc. 



Trypeta {Euaresta) araneosa, n. sp., 9 • Grayish-black, the head and 

 its appendages (except a portion of the occiput), halteres and legs except 

 sometimes a portion of the femora, yellowish ; bristles black, the short 

 pile yellowish ; front bearing four bristles each side, scutellum bearing 

 four bristles ; wings brown, the following spots hyaline : three in costal 

 cell nearly filling that cell (none between apices of auxiliary and first 

 veins), four in marginal cell, of which tv/o are near the base and two be- 

 tween apices of first and second veins ; five in sub-marginal cell, of which 

 one is at the base, two near the middle and two between apices of second 

 and third veins ; five in first posterior cell, the one in the apex reaching the 

 wing margin; three in the second posterior cell, each of which crosses that 

 cell ; four in third posterior cell, from four to seven in the discal cell, one 

 of which touches the vein at the base of that cell ; and three in first basal 

 cell ; second basal, anal and 'axillary cells largely hyaline ; first vein 

 bristly, the others bare ; ovipositor scarcely longer than the last abdom- 

 inal segment ; length, 4 mm. Southern California. Four females, in 

 January and February. 



The wings somewhat resemble Figure 21, Plate X., of Loew's Mono- 

 gragh, but the stigma is wholly brown and the base of the wing to apex 

 of auxiliary vein is almost wholly hyaline, excepting a brown stieak cross- 

 ing the third posterior cell near its base. 



Trypeta {Euaresta) stelligera, n. sp., S • Black, the head and its 

 appendages (excepting the occiput) the halteres and legs, yellow ; thorax
