Brachyopa vacua Osten Sacken. 
Cohasset, Mass., June 5, 1904 (Owen Bryant). It has also 
been taken at North Saugus, Mass. 
Brachyopa media Williston. 
A specimen was captured on the summit of Mt. Greylock, Mass., 
June 15, 1906; on the flowers of the wild cherry. Mr. E. J. Smith 
also collected a specimen at Sherborn, Mass. A peculiar variation 
of this species, in which the abdomen is entirely black, was obtained 
by Mr. E. Daecke at Castle Rock, Delaware County, Pa., 
May 19, 1901. 
Sphegina campanulata Robertson. 
This species seems to be quite generally distributed throughout 
New England:—Branford, Conn., May 25, 1905 (Rev. H. W. 
Winkly); Hampton, N. H., June 25, 1908 (S. A. Shaw); Machias, 
Maine, July 17-22, 1909 (C. W. Johnson). 
Xanthogramma tenuis Osburn. 
A single example of this western species was obtained by the 
writer at Ethan Allen Park, Burlington, Vt., June 24, 1906. 
Eumerus strigatus Fallen 
Pipiza strigata Fall., Dipt. Seuc. Syrphici, 61, 8, 1817. 
Eumerus grandicornis and funeralis Meigen, Syst. Beschr., IIT, 208, 1822. 
E. lunulatus and planifrons Meigen, Syst. Beschr., III, 209, 1822. 
E. eneus Macq., Soc. Sci. Lille, 1827, p. 269; Hist. Nat. Ins. Dipt. I, p. 528, 1834. 
Two specimens of this European species have come under the 
writer’s observation. The first was obtained at Brookline, Mass., 
June 1909; the second was received from Mr. M. C. Van Duzee 
who collected it at Buffalo, N. Y., June 3, 1908. The genus has not 
been recorded from America, but the presence of this species in 
such widely separated localities seems to preclude the possibility 
of recent introduction. The above synonomy is that given (in 
part) in the Katalog der Paliiarktischen Dipteren, III, 137.
