SMITHSONIAN CATALOGUE OF THE DESCRIBED DIPTERA OF 

 NORTH AMERICA. 



By BARON R. OSTEN SACKEN. 



OCTOBER, 1859. 



The following N. American species have been omitted in this enumera- 

 tion, principally because the works containing them have not been pro- 

 cured in time : — 



Cuterebra frontinella Clark. Illinois. Bracy Clark, of the insect 



called Oistros by the ancients, etc., in the Trans. Lin. Soc. XV, 

 402, 1826. 



Cuterebra emasculator Fitch. U. States. A. Fitch, in the Trans. 



N. Y. State Agric. Soc. XVI, 482, 1856. 



Calobata ruficeps Guerin. Cuba. Guerin, Iconogr. du regne anim. 



Ill, 553, tab. ciii, fig. 7. 



Lepras Servillei Guerin. U. States. Ibid. Ill, 541, tab. xlvi, fig. 3. 



Anthomyia impudica Reiche. Greenland Reiche, Bullet. Soc. 



Entom. de France, 1857, 8. (It is a Cordylura according to Loew, 

 Berliner Ent. Zeitschr. 1858, 347.) 



Pangonia macroglossa, Gymnoplistia annulata. These two species, 



by Weshvood, are contained in his Insectorum novorum exoiicorum, 

 etc. (London and Edinburgh Philos. Mag. 1835), quoted in the Cat- 

 alogue, etc., among the authorities on page xvii. By some mistake 

 they have been omitted in the enumeration of the species. The 

 first must be inserted on page 19, after Pang. incisuralis Say, the 

 second on page 8, before Ctenophora. 



Chrysotoxum bicinctum Meig. This European species is mentioned 



by Mr. Loew as occurring in N. America ( Verh. Zool. Bot. Ver. in 

 Wien, 1S5G.) 

 Syrphus anchoratus Macq. from Brazil, occurs also in N. America. 

 (Conf. Macg. Dipt. Exot. etc., at the end of the description of this 

 species.) 

 A few more N. American diptera have been published since the appear- 

 ance of the Catalogue, or almost contemporaneously with it ; they are con- 

 tained in the following works : — 



Walkek, F. — Characters of undescribed diptera in the collection of W. W. 

 Saunders, etc. In tbe Trans. Entom. Soc, new series, vol. iv. part 

 5th (1857) ; part 6th (1S58). Ten new North American species.
