106 THE NORTH AMERICAN SPECIES OF DROSOPHILA. 



D. excita Giglio-Tos is an ephydrid. 



D. flaveola Meigen, to Scaptomyza. Does not occur in the region. 



1). frontalis Williston, to Leucophenga. 



D. fronto Walker, not recognizable from the description. 



D. Jusca Coquillett, not recognized. The type specimen has been lost, and it was the only 

 one that Coquillett recorded. I have been unable to find any other material so 

 labeled by him. The species, which was described from Porto Rico, suggests 

 D. lulzii Sturtevant, but is stated to have only two orbitals. If this is correct the 

 species is not one that I have seen. 



D. graminum Fallt^n to Scaptomyza. 



D. liinbata Williston, new name is D. nebulosa Sturtevant. 



D. linearis Walker, probably not a Drosophila. Suggests either Scaptomyza or a geomyzine. 



D. maculosa Coquillett to Leucophenga. 



D. mexicana Macquart, not recognized. The description would fit almost any large, dark 

 species, and there are several such that probably occur in Mexico. This species 

 can hardly be identified without an examination of the type. 



D. minuta Walker, not recognizable from the description. 



D. multipuncta Loew, synonym of D. guttifera Walker. 



D. neglecta Sturtevant, a manuscript name for D. melanica Sturtevant, used by Metz 

 (1916, Journ. Exper. Zool., 21, legend to plate 2). 



D. nigricornis Loew, a manuscript name. It has gotten into the literature only through 

 the description of a fungus said to have been found on it. This fungus, Appendicu- 

 laria entomophila Peck {Stigmatomyces entomophilus Thaxter), was stated (1884, 

 Science, 4, 25) to have been collected by Zabriskie at Nj^ack, New York, on a fly 

 that was determined by H. A. Hagen, of Cambridge, as D. nigricornis Loew. 

 From a specimen in the American Museum of Natural History and three in the 

 Museum of Comparative Zoology at Cambridge it appears that the fly was really 

 D. funebris Fabricius, on which the same fungus has been found in Europe (see 

 Thaxter, 1895, Mem. Amer. Acad., 12, 300). Hagen evidently made his deter- 

 mination by comparison with specimens that are still in the Loew collection 

 labeled "D. nigricornis Loew." These are evidently Drosophila, but not D. 

 funebris. The only ones with locality label (D. C.) are D. sulcata Sturtevant and 

 D. melanica Sturtevant. 



D. obesa Loew to Pseudophortica. t 



D. obscuripennis Loew to Leucophenga. 



D. orbitalis Sturtevant to Zaprionus. 



D. pallida Williston, new name is D. ivillisioni Sturtevant. 



D. pleuralis Williston to Mycodrosophila. 



D. pollinosa Williston to Paratissa (Ephydrinse). 



D. procnemis WiUiston to Chymomyza. 



D. projectans Sturtevant to Mycodrosophila. 



D. punctulata Loew is a synonym of D. repleta WoUaston. 



D. quadrimaculata Walker to Leucophenga; is a synonym of D. varia Walker. 



D. slossonoe Coquillet, a manuscript name, used by Johnson (1913, Bull. Amer. Mus. Nat. 

 Hist., 32, 88). I have been unable to find any specimens so named. 



D. terminalis Loew to Scaptomyza. 



D. thoracis Williston to Mycodrosophila, 



D. valida Walker to Minettia (Lauxaniinae). Is an earlier name for Sapromyza macula Loew. 



D. varia Walker to Leucophenga. 



D. vittata Coquillett to Scaptomyza. 



Genera that Have Been Included in the DrosophiliNjE but are not 



HERE so CONSIDERRD. 



Asteia Meigen. 1830. Sysfey Beschr., 5, 88. Here considered as the type of a subfamily, 

 the Asteinae. This treatment is not new, but has recently been largely given up. 



Crepidohamma Enderiein. 1915. Wien. ent. Zeit., 34, 185. Belongs in the Asteinse, and 

 is a sjTionym of Sigaloessa Loew. 



Drosomyia de Meijere. 1904. Bijd. Dierk., 17, 114. De Meijere (1908, Tijd. Ent., 51 

 137) himself refers this genus to the Lauxaniinae, making it a synonym of Sapro- 

 myza.
