sub-marginal cells; the next band begins just before apex of second vein 

 and crosses the vving, passing over the posterior cross-vein, widest and 

 angled at the fourth vein, the band having the form of a bayonet ; a 

 brown spot fills apex of first posterior cell (except sometimes a spot in 

 its extreme apex), and encroaches on the sub-marginal and second 

 posterior cell ; length, 3 to 4 mm. Southern California. One male and 

 two females, 



The wings somewhat resemble Figure 16, Plate IX„ Loew's Mono- 

 graph, but the first band is at apex of second basal cell, there is an 

 additional brown costal spot between the second and third bands, the 

 third band begins at apex of second vein, etc. 



Trypeta {Aciura) aplopappi, n. sp., $ % . Black, the pleura 

 largely brown, the head and its appendages, the legs except 

 the coxae, yellow, a brown vitta on outer side of front femora; 

 knob of halteres bright red ; bristles black, the short pile light 

 yellow; front bearing four bristles each side, the scutellum bear- 

 ing only two ; abdomen shining, not bristly ; ovipositor flattened 

 only at apex, as long as last two abdominal segments ; wings of nearly an 

 equal width, dark-brown, the following spots whitish hyaline : two in cos- 

 tal cell, two in marginal cell beyond apex of first vein, the second spot 

 extending half-way across the submarginal cell ; one in first basal cell 

 opposite apex of first vein, one in upper outer angle of discal cell, a 

 basal spot and oblique streak crossing second posterior cell, five in third 

 posterior cell, three of which are on the wing margin ; from two to four 

 in axillary angle ; first vein bristly, the others barq ; length, 4 mm. 

 Southern California. Three males and two females, which issued in 

 April and May from irregular galls, about 8 mm. long by 4 in diameter, 

 on the smaller branches oi Aplopapptis pinifolius. 



The wings are very similar to Figure 8, Plate X., of Loew's Monograph, 

 but there is no hyaline spot in the first posterior cell, only one in the first 

 basal, axillary angle not wholly hyaline, etc. 



Trypeta {Carp/iotricha) cultaris, c\. sp., (? 5- Agrees in all respects 

 with Loew's description and figure of culta (Monographs, etc., IIL, 

 pages 276 to 279) with these exceptions : Ovipositor not longer than the 

 last three abdominal segments ; wings having only one brown ray between 

 apices of second and third veins ; no darker spot in second posterior 

 cell ; length, 6 to 7 mm. Southern California. One male and two 

 females, in January.
