In the cases of four new species [Drosophila virilis, robusta 

 melanica, and modesta) I have reared offspring from the individ- 

 ual selected as the type specimen. In these cases the mate, to 

 which the type was bred, is designated allotype ; and all descend- 

 ants of the type are called gonotypes. 



My studies have been greatly facilitated by loans of material 

 and other favors received from Dr. F. E. Lutz, Messrs. C. W. 

 Johnson and F. Knab, and Profs. J. M. Aldrich and A. L. 

 Melander, and others. To them I wish to express my most 

 sincere thanks. 



The type specimens of the new species described here are 

 in the following collections: 



American Museum of Natural History, New York City : 

 Drosophila ramsde?ii, saltans, earlei, virilis, robusta, 

 melanica, melanissima, affinis, caribea, cardini, modesta, 

 putrida, florce, lutzii, prognatha, quadrata. 



United States National Museum, Washington, D. C: 



Drosophila sulcata, pseudomelanica, orbitalis, superba, 

 projectans. 



A. L. Melander: 



Drosophila melanderi. 



J. M. Aldrich: 



Chymomyza aldrichii. 



Many paratypes are in the author's collection, in the four 

 named above, and in other collections. 



Leucophenga Mik. 1886. Wien. Ent. Zt. 317. 



Drosophila maculosa Coq. 1895, Proc. Acad. Nat. Sci. 

 Phila. XL, is a synonym of L. quadrimaculata Walk. 1856, 

 Dipt. Saund. IV. The species will be easily recognized by its 

 large fiat yellow palpi. I have seen specimens from New York, 

 District of Columbia, North Carolina, Florida, Cuba, Domin- 

 ican Republic, Peru. These include Coquillett's type. 



Drosophila bimaculata Lw. from Cuba, is a Leucophenga. I 

 have examined Loew's specimen in the Museum of Comparative 

 Zoology at Harvard, and two Cuban specimens in my own 

 collection. 



"Leucophenga vittata Coq." of Johnson, 1913, Bull. Am, 

 Mus. Nat. Hist. XXXII. 88 is a Scaptomyza.. (See below).
