the hyaline spots and spaces are larger and somewhat differently ar-

Eurosta aterrima, sp. nov. (PI. IV, Fig. 2). 



9 . Dull black ; head and its appendages, scutellum, pleura and legs yellow ; 

 front remarkably broad, more brownish yellow ; bristles black ; face lighter, excavated ; 

 oral opening large, margins projecting ; proboscis and palpi short ; antennas short, 

 third joint rounded, nearly as broad as long, arista brown, yellowish at base ; thorax 

 with short sparse white pile and black bristles ; the four bristles of the scutellum 

 black ; posterior femora with an inconspicuous black spot on under side near the base ; 

 abdomen wholly dull black with short sparse white pile ; ovipositor flattened, black, 

 reddish brown latterly, a little longer than the preceding segment. Wings with a 

 brown picture, the basal portion of the wing, a broad deep irregular incision reaching 

 from the posterior margin to the third vein and the following spots whitish hyaline : 

 one on the costa just before the stigma reaching as far back as the second vein ; four 

 in the marginal cell beyond the tip of the first vein ; first and second small, third and 

 fourth large ; a large one in the sub-marginal cell ; two larger ones in the first posterior 

 cell and a large indentation in the second posterior cell reaching from the posterior 

 margin to the fourth vein ; the six spots last named foiming an irregular hyaline band 

 across the wings. The other hyaline spots which are much smaller are scattered over 

 various parts of the wings, but are confined for the most part to that portion beyond 

 the hyaline cross-band. Beside these hyaline dots the brown picture is marked by 

 numerous small yellowish brown spots which are most numerous in the middle portions 

 of the wing along the second vein. The stigma is darker and marked by two 

 yellowish spots. In the first of the hyaline indentations arising from the posterior 

 margin are four or five small isolated brown spots ; in the second indentation only one 

 such spot. Length, 5 mm. One female. 

 Habitat: Colorado.

 broad slightly narrowed anteriorly ; face lighter yellow somewhat hollowed out ; oral 

 opening rather large, margin slightly projecting ; proboscis and palpi prominent, palpi 

 quite long and narrow ; antennce darker yellow ; arista yellow, darker toward the tip; 

 the black on the cephalic aspect of the thorax is not covered with white pollen and

 the others of the thorax and head, brownish ; metanotum black, yellow at the sides 

 and for the most part covered with gray pollen ; legs yellow ; tarsi, especially the last 

 segment, darker; wings hyaline; veins yellowish, the stigma, the costal vein, the
