324 THE CANADIAN ENTOMOLOGIST 



Sciomyza apicata Loew. 



This species is a synonym of S. nigrimana Meigen. The 

 specimens in the Illinois State Lab. Nat. Hist, collection, from 

 Algonquin, 111., are in all particulars identical with this European 

 species, which is well described by Schiner, Fauna Austriaca, Vol. II, 

 p. 45. The species bears a close resemblance to glabricula Fallen, 

 which has been recorded by Coquillett from Alaska, but the latter 

 has short, narrow wings, and the fore tarsi are entirely black. 



Sciomyza strigata v. d. Wulp. 



This species is a synonym of S. trabeculata Loew. I have 

 examined seven specimens in the above-mentioned collection from 

 Tampico, Mexico, December 29, 1908. Van der Wulp obtained 

 his specimens from Mexico City and Vera Cruz, while Loew ob- 

 tained his from Texas. The species is close in general appearance 

 to nana Fallen, differing noticeably in the wing markings. In 

 nana the submarginal cell has only one transverse brown mark 

 near the apex, while in trabeculata there are five or six distinct 

 fascia? in this cell. There is also in the latter species a small 

 appendiculate vein, on the posterior surface of the fourth vein, 

 at about the middle of the last section, which I have not seen in 

 any specimen of nana. 



Tetanocera lineata Day. 



This species belongs to the genus Hidroneura Handel and is 

 synonymous with H. rufa Panzer of the European fauna. Mem- 

 bers of Hidroneura may be distinguished from other genera in 

 Tetanocerinae by their possession of the following characters: 

 Antennae projecting straight forward, second joint not longer than 

 third, the latter obtuse at apex and without apical hairs; arista 

 thickened, bare; frontal and thoracic bristles comparatively weak; 

 outer cross vein biangulate. 



I have before me three specimens belonging to this species 

 from Algonquin, 111., Nason, taken on July. 20, October 3 and 16; 

 one specimen, Urbana, 111., May 27, 1889, taken at light, C. A. 

 Hart, and one specimen, Lake Geneva, Wisconsin, taken by sweep- 

 ing along shore, west end, September 2, 1892, C. A. Hart.
