the species. The whole body is clothed with rather 

 long, light colored pile. 



22. Xylota chalvbea, Wiedeman. I took one 

 specimen of this species, August 5, "98, at Medina. 

 When I first saw it, it was resting on a log and I took 

 it to be one of the ichneumon flies, but when it flew, 

 my attention was attracted, as it then appeared like a 

 dipterous insect. Its black wings and body together 

 are characters seldom united in the same species in 

 the diptera. 



33. Syritta pipiens, Linn. A very common 

 form, in August, along small streams in all parts of the 

 State. It has some resemblance in coloration and 

 actions to some of our hymenopterous insects 

 commonly called sweat bees. 



24. Spilomyia longicornis, Loew. Although 

 distributed all over the State, does not appear to be 

 common anywhere. I have taken it at Medina. Aug. 

 15, and at Portsmouth, Sep 9. 



25. Milesia ornata, Say. This is one of the 

 largest species of the family. Some specimens 

 measure more than 22 millimeters in length. It has 

 been taken at Newark I K. C Osburn. )August 23, '98, 

 and at Portsmouth. Sep 9, '97. At the latter place it 

 appeared to be common and was found visiting the 

 flowers of Impatiens fulva, in company with the pre- 

 ceeding species.
