states: Maine, New Hampshire, Vermont, Massachusetts; and 

 also from Montreal, Canada. 



There are female species in our Laboratory collection from 

 Algonquin (Nason) and Urbana, 111. (Malloch). The dates 

 range from May 9 to August 12. Three of the Urbana specimens 

 were taken on the inner side of windows in the basement of the 

 Natural History Building of the University of Illinois, the other 

 on a tree-trunk on the campus. 



Clusiodes flavipes Williston. 

 Heteroneura flavipes Williston, Trans. Ent. Soc. London, 1896, p. 376. 



This species, which was originally described from examples 

 obtained on the Island of St. Vincent, West Indies, has been 

 recorded by Johnson as occurring in Florida. 



I have seen one specimen of this species from the collection of 

 Professor J. M. Aldrich, taken in the type locality. 



Clusiodes geomyzina Fallen. 

 Heteroneura geomyzina Fallen, Agromyz., 1823, 2, sp. 2. 



I have not seen this species. It occurs in Europe and has 

 been recorded by Johnson from Maine. 



Clusiodes apicalis Zetterstedt. 



Heteroneura geomyzina var. apicalis Zetterstedt, Dipt. Scand., Vol. 7, 

 p. 2789. 1848. 



This species is rather doubtfully distinct from the foregoing 

 one, but always has the apical third of the wing infuscatecl, 

 whereas geomyzinae has the infuscation extending to the apex 

 of first vein. 



In our collection here there is one female example that is 

 referable to apicalis. 



Locality, Algonquin, 111., May 20, 1897 (Nason). 



There is no previous record of the occurrence of the species in 

 America. 



Clusiodes albimana Meigen. 



.Heteroneura albimana Meigen, Syst. Beschr. Eur. Zweifl. Ins., Vol. 6, 

 p. 128. 1830. 



Recorded by Johnson from the following states: Maine, New 

 Hampshire, Vermont, Massachusetts, New Jersey; and also from 

 Quebec, Canada. 



Probably occurs in Illinois, but not yet taken here so far as I 

 am aware. I have seen two specimens from Waubamic, Parry 

 Sound, Ont. (coll. Aldrich).
