THE CANADIAN ENTOMOLOGIST. 73 



These differences are constant in the numerous specimens examined 

 but not now before me. So far as I am aware, the typical cidta does not 

 occur on the Pacific coast. 



Trypeta (Neaspilota) signi/era, n. sp., $ ? . Yellow, dorsum of 

 thorax and metanotum except the sides, opaque grayish-black, the abdo- 

 men sometimes brown; front bearing five bristles each side, the scutellum 

 bearing four ; ovipositor flattened, as long as the last three abdominal 

 segments ; wings hyaline, basal half or less of space between apices of 

 auxiliary and first vein brown ; first vein bristly, the others bare ; length, 

 3 mm. Southern California. Six males and one female. 



The wings are like Figure lo, Plate XL, of Loew's Monograph, except 

 that the apex of the stigma is broadly hyaline, 



Trypeta (Tephritis) baccharis.n. %'^., S ?• Yellowish-brown, base 

 of each abdominal segment and spot each side of middle of metanotum, 

 dark grayish-brown ; front bearing four bristles each side, scutellum also 

 bearing four bristles ; wings narrow, of nearly an equal width, opaque 

 white mottled with brown, which is broken up into spots, except a border 

 on the apex beginning between apices of first and second veins and ex- 

 tending nearly to axillary angle, where the brown is very faint; along 

 the wing margin this border contains a white spot in each angle of the 

 sub-marginal cell, entire apex of the first posterior cell, three spots in 

 apex of second posterior cell, and seven between this cell and the 

 axill'ary angle ; the brown spots form an indistinct broad band, reaching 

 from the stigma to the wing margin at lower end of the posterior cross- 

 vein ; first vein bristly, the others bare ; length, 5 mm. Southern Cali- 

 fornia. Nine males and seven females, which issued from January to 

 April from irregular oval galls about 12 mm. long by 4 in diameter, on 

 tender twigs of Baccharis vimlnca. 



The wings somewhat resemble Figure 5, Plate XL, of Loew's Mono- 

 graph, but are much paler, the darker portions forming two cross-bands, 

 one near the middle, the other at the apex of the wing. 



Trypeta \Euaresta) Californica, n. sp., $. Black, the head and its 

 appendages, corners of thorax, margin of scutellum, large spots on pleura, 

 and the legs, yellowish, halteres pink, pleura near the wings, and bases of 

 the latter, tinged with pink ; thorax and scutellum opaque gray pollinose, 

 abdomen glabrous, shining ; front bearing four bristles each side, the 

 scutellum bearing only two ; ovipositor longer than the last three abdom- 

 inal segments, over three times as broad at base as at the apex ; wings
