costal cell; the usual hyaline space beyond the tip of first vein is 

 clearly defined, ending abruptly at third vein; there is a small drop 

 just beyond the ending of the second vein; the hyaline of tip inter- 

 rupted on third and fourth veins, the s|)ot arising at end of sixth 

 vein is large and invades the discal cell; the specimen described has 

 an adventitious cross vein in both wings, between the second and 

 third veins, bisecting the submarginal cell: third vein with much 

 stronger bristles than in s<>/i(faginis. 



Lengh, 7 mm. 



A single specimen from Arizona (Morrison). 



This species is allied to E. c-om/nah\i\. is smaller and of lighter color. 

 Its face is more deeply excavated, the oral margin more projecting, 

 and the palpi more exserted; abdomen slenderer than in allied species, 

 with pile mostly yellow, while in comma it is black; the wings differ 

 in their picture. 



Eurosta reticulata n sp. (1*1 \ll. I". G.) 



Male and female. Dark brown.— Head of a yellowish -brown. 

 I'ront very wide with weak black bristles, slightly darker than the 

 face. Antennae short, clay yellow; third joint with an anterior angle, 

 arista incrassate at base. l-ace (luite strongly excavated, on the sides 

 below with a few short hairs; oral border projecting, mouth rather 

 large. Myes moderately large, of greater extent than in so/iddi^/nis. 

 Cheeks broad, with stout light colored pile. Proboscis short. Palpi 

 broad, extending beyond oral margin. Thorax broad, dark, dingy 

 brown, blacker on the dorsum; with short whitish pile and light 

 colored pollen, through which the brown of the ground color shows 

 in small round spots. Scutellum very convex, with four bristles. 

 Metathorax black. Abdomen broad, dark brown, with a pollinose 

 light stripe down the middle, and similar pollen in irregular patches, 

 especially on the margin and sides of segments. The brown shows

 Stictocephahx van. Ovipositor conical, a little flattened at tip in one 

 specimen; black, or partly dark red. Legs yellowish-brown, femora 

 darker. Wings broad, with very obtuse tip, more evenly reticulate 

 than in so/ii/aginis: the picture a deep brown; the hyaline predomi- 

 nates from near the tip of sixth vein anteriorly to middle of wing; at 

 the tip of wing, broailly, and just distad of the end of the first vein; 

 cross veins perpendicular; bristles of third vein well developed.
