1913] Johnson — A Study of the Clusionidce {Heteroneurida) 101 



Clusia lateralis Walker.

The nineteen specimens before me show the following distri- 

 bution: Maine — Northeast Harbor, July 4 (Dr. C. S. Minot); 

 Vermont — Norwich, July 7, Burlington, June 23, and St. Johns- 

 bury, June 27; Massachusetts — Auburndale, August 9, Chester, 

 August 4-7, and Bash Bish Falls, June 27; Connecticut — Middle- 

 town, June 19; New Jersey — Riverton, July 6; Pennsylvania — 

 Folsom, June 12, and Glenside, May 26 (C. W. Johnson); Canada, 

 (Beaulieu), July 16. 



Cheetoclusia affinis sp. nov. 



Male: Head light yellow, palpi and antenna? yellow, arista black, densely plu- 

 mose, ocelli black. Thorax yellow, abdomen brownish, tip yellow. Legs yellow, 

 anterior tibiae and tarsi brown. Halteres yellow. Wings yellowish hyaline. 

 Length 2.5 mm. 



Female: Similar to the male except that the anterior tibiae and tarsi are black 

 and the abdomen shining with an obscure dorsal line and black tip. Length 3 mm. 



Holotype, Riverton, N. J., June 18 (C. W. J.); allotype, James- 

 burg, N. J., July 15 (J. B. Smith). Both in the author's collection. 



The Jamesburg specimen was referred doubtfully to Clusia Uava 

 Meig. in Smith's Insects of New Jersey. The Fort Lee specimen 

 also referred to that species is H. flaviseta. As this is the only 

 American record for C. flava, it should be omitted from the list 

 of North American Diptera.
