triangular spot between the apices of third and fourth vein, the base of 

 the triangle resting on the margin of the wing ; but again between 

 these extreme forms I find intergradations, some with only two rays 

 and a trace of a third, others with two complete rays and a third al- 

 most complete, etc. The second and third groups might be con- 

 sidered as distinct varieties, but certainly not distinct species. 

 Habitat : Wash., Oregon, Ida., S. D., Fla. 



Eurosta solidaginis Fitcli. 



I have a large series of this species from widely different localities, 

 showing considerable differences in the picture on the wing and the 

 coloring of the body. 



Habitat : Wash., Ida., S. D., Minn., Nebr., X. H. 



Eurosta comma Wicd. 



A single male, the hyaline space at the tip of the sixth vein is 

 much larger than in Loew's figure (Mon. Ill, Tab. XI, fig. 2). 



Eurosta reticulata S)wuk Colo., S. D., Minn. 



Eurosta conspurcata, sp. nov. (PL IV, Fig. i). 



$ . Brown ; front very broad, brownish yellow ; face whitish, somewhat hollowed 

 out ; mouth opening large, edge projecting ; antennte light yellow, third joint shorter ; 

 arista yellowish darker toward tip ; bristles of the head, thorax and the four bristles 

 of the scutellum, black ; thorax broad, very convex with short reddish and black pile ;' 

 nietanotum black except on the sides which are reddish brown ; legs reddish yellow, 

 femora darker ; front femora much darker, slightly incrassated, with black bristles be- 

 neath ; abdomen quite broad, brown with thick short black pile; posterior margin of 

 segments ligther ; wings rather broad rounded, brown with large round or roundish 

 whitish hyaline spots and smaller yellowish spots. In the third posterior cell several 

 of the hyaline spots are united so as to appear as a single large hyaline space ; in the 

 second posterior cell three or four, and in the first posterior cell three, of the spots are 

 thus united. Beside these, the following spots also occur : Two or three in the 

 costal cell before the tip of the auxiliary vein ; three in the marginal cell, two of which 

 are just beyond the tip of the first vein, the third a little before the tip of the second 

 vein ; four in the sub-marginal cell, three near the tip, the other over the anterior 

 cross-vein ; one in the first basal cell below the stigma ; one in the discal cell below 

 the anterior cross-vein, and a few other smaller ones over the posterior portion of the 

 wing. There are two spots on the stigma, one yellowish, the other nearly hyaline. 

 Beside the yellowish dots in the middle portion of the wing there is a small yellowish 

 area in the region of the anterior cross-vein ; in the first posterior cell is a somewhat 

 darker shining spot which at an oblique view shows much darker. The first and 

 third veins bristly. Length, $ 5 mm. One male. 



Habitat : Washington, New Hampshire, New Jersey. 



The picture of the wing resembles that of JS. reticulata Snow, but
