does not reach the posterior margin; the first and second very diver- 

 gent near their origin. These bands are darker on their borders and 

 ends than upon their middle. Cross veins very near together, nearly 

 perpendicular; third vein naked; last segments of third and fourth 

 veins parallel, enclosing a narrow first posterior cell; lower corner of 

 anal cell scarcely prolonged.

One specimen, Montana (Morrison). 



CEdaspis minuta n. sp. (PI. VI, f. 2.) 



A single badly preserved male from Montana (Morrison) affords 

 sufficient grounds in its small size and wing characters, for the intro- 

 duction of a new species Moreover the face is very short; the eyes 

 are not much longer than wide; the cheeks are of moderate breath; 

 the femora are dark brown except their tips. The pile and bristles of 

 rhe body are mostly rubbed off. Wings with basal spot and three bands 

 brown. The hyaline intervals whitish; the bands are of subequal 

 width, the first one being slightly the broadest; the second and third 

 bands barely come in contact on the third vein. The first and second 

 bands are much more divergent at their beginning than in CE. atra 

 Loew (Monogr. Ill, Pi. XI, f. 17); cross veins perpendicular, not as 

 approximate as in the preceding species; third vein without bristles; 

 lower corner of anal cell slightly drawn out. 



Rhag-oletis pomonella Walsh. (PI. VI, f :}.^ 



Specimens of both sexes from Michigan, District of Columbia 

 (date of June 15) and Maine (Harvey), are blacker in color than is 

 indicated by Loew's description (Monogr. Ill, p. 265). The black 

 stripe on the anterior femora is sometimes lacking. As Loew's 

 description applies only to the female, it may be added that the male 

 besides being somewhat smaller, has three whitish abdominal bands 

 instead of four as in the female; the hairs of the hypopygium are 

 white; the femora are darker. 



The wing band that covers the posterior cross vein is generally a 

 little broader at the middle, and longer than in the specimen figured, 

 which was a little faded. 



Rhagoletis zephyria n. sp. (PI. VI, f. 1.) 



Male. Similar to R. pomonella but much smaller. Blackish- 

 brown, the pleurae and femora more brown; the two pollinose stripes 

 each side of the middle line of the dorsum obsoletely divided; the 

 dark brown bands of wings of lighter color than in pomonella; the 

 fourth band fills out the tip of wing to greater extent; the hyaline
