lines ; pleurae with a yellowish sericeous reflection ; halteres pale, 

 basis of the knob infuscated. Abdomen brownish, with a gray 

 dust, forming two more or less distinct longitudinal stripes along 

 the back. Feet yellowish tawny ; femora with a brown band at 

 the tip, sometimes with a second one, preceding it ; tips of the 

 tibiae and of the tarsi brown. Wings with a pale brown picture, 

 the margins of which are darker brown ; the spots, taken singly, 

 are more or less circular, but most of them are confluent, so as to 

 form several bands across the wing. Two principal bands thus 

 formed by confluent circular spots occupy the middle of the wing ; 

 one runs from the costa across the origin of the praefurca to the 

 tip of the seventh vein ; the other is broader and begins at the 

 costa, includes the discal cell, and ends at the posterior margin 

 on both sides of the tips of the fifth and sixth veins ; a smaller 

 brown picture fills the basal portion of the wing, and seven almost 

 confluent round spots, the apical portion. 



Hab. United States. I have seen specimens from Georgia (Ber- 

 lin Museum), Maine (Packard), and Illinois (Kennicott), and have 

 taken them abundantly in May and June near Washington, D. C, 

 and in the White Mountains. A number of 'the specimens from 

 the latter locality have the picture on the wings very pale, almost 

 obsolete, and, at first sight, might be taken for a different species.
