NOTES on the NOMENCLATURE of SOME HYMENOPTEEA. 



By T. D. A. Cockerell, N. M. Agr. Exp. Sta. 



Pseudosphex and Neosphex. 

 The genus (or subgenus of Sphex) called Pseudosphex by 

 Taschenberg (1869) cannot bear that name, on account of the 

 lepidopterous Pseudosphex, Hbn. (1818), which Mr. W. F. Kirby 

 treats as a good genus. According to Kohl, Neosphex, Eeed, 

 1894, is the same as Pseudosphex, Tasch., so it is not necessary 

 to propose a new name. 



Gundlachia. 



The name Gundlachia properly belongs to a genus of Mollusca, 

 described by Pfeiffer in 1819. 



Gundlachia, Herr.-Schaff., 1866, applied to a Trichurine moth 

 from Cuba, will stand as Burtia, Grote ; the only species will be 

 Burtia cruenta (Herr.-Sch.). 



Gundlachia, Cresson, Proc. Ent. Soc. Phila. 1865, p. 194, 

 proposed for the peculiar Cuban bee, Centris (?) cornuta, Cresson, 

 may be changed to Heterocentris, nov. nom. 



Megachile inermis. 

 This name was proposed by Provancher (Add. Faune Hym. 

 p. 323) to replace his simplex, preoccupied by Smith. Dalla 

 Torre's name simplicissima for the same insect is therefore need- 

 less. M. inermis, Eadoszkowski, Hor. Soc. Ent. Eoss. 1893, 

 p. 47, from Transcaspia, requires a new name, and may be 

 termed M. mitis, nov. nom. 



Hijlatts minutus, Fabr., 1798. 

 Fabricius, in 1804, referred this to Prosopis, and it has so 

 stood ever since. From the description I have little doubt it is 

 a male Halictus, but the name is preoccupied in that genus by 

 Halictus minutus (Schr. 1781). As the Fabrician insect cannot 

 well be recognized from the description, it is not worth while to 

 propose another name for it. 



Macgillivraya. 

 Mr. Ashmead (Canad. Entom. 1898, p. 257) proposes this 

 name for a genus of sawflies. The name was used by Forbes in 

 1851 for a genus of Mollusca. 



Eunomia. 



Eunomia, Cresson, 1875, is perhaps only a subgenus of Nomia, 

 Latr., 1805. Cresson's name, however, is preoccupied by 

 Eunomia, Hbn., which Kirby treats as a valid genus. It may 

 be called Dieuuomia, nov. nom. The species are D. heteropoda 

 (Say), D. apacha (Cress.), and D. marginipennis (Cress.).
