NOTES. 243 



Hah. Tarrytovm, N. Y. July 1871 ; Manlius, in Western New York 

 (J. H. Comstock). 



This species resembles very much the european Porjihyrops antcn- 

 ?wf»s described and figured in tlie Ann. Soc. Entom. de France, 1835, 

 p. 659 5 Tab. XX, c, as Anglearia mitcnnafa. 



190. Mr. Kowarz has given important papers on the european 

 species of Chrysotus in the Verb. Zool. Bot. Ges. 1874, and on Medeterus 

 1. c. 1877. 



191. Chrysotus pallipes and obliquus. According to Schiner, Novara, 

 p. 221, these species have also been received from South America. 



192. Sympycnus. There is a genus Si/nqrycua Charp. 1840 (Neuropt). 



193. Psilopus pallens. This species, which is not uncommon along 

 the Atlantic seaboard, and generally occurs about buildings, is the same 

 as P. alhonotatus Loew, from Rhodus. In Mr. Bergenstamm's collection 

 in Vienna I saw a specimen from Barcelona, in Spain. Very probably, 

 the species has been imported on ships to America. 



194. Microdon. About the european species of this genus, see 

 Locw, Verb. Zool. Bot. Ges. 1856. 



195. Ceratophyia fuscipennis Macq. The genus Ceratophyia (Wiede- 

 mann, Anal. Ent. 1824; Auss. Zw. II, p. 79; Tab. IX, f. 5) is separated 

 from ]Microdon on account of the absence of spines or even tubercles 

 on the scutellura. This is not a sufficient reason for maintaining this 

 genus, which in other respects, does not differ from a typical Microdon. 

 The latter genus, as it is understood now, contains many species with 

 much more important structural differences, and the existence of the 

 genus Ceratophyia, until those other species are not likewise separated, 

 is only misleading. 



I believe I recognize C. fuscipennis Macq. in a specimen from 

 Texas, in Dr. Loew's typical collection. It is recognizable by the length 

 ot its third antennal joint; in general appearance and coloring it looks 

 very much like Microdon gJohosus. Macquart had it from „Philadelphia", 

 but I do not quite trust his statements about localities and suspect that 

 he sometimes labelled Pliiladtlpliia or Baltimore specimens which he 

 had received from these cities, but which had a more southerly origin. 

 (For instance Lampria riihrircntris which is likewise frequently received 

 from Texas, but which is labelled „Philadelphia" by Macquart.) 



196. ChymopMla splendens Macq., Hist. Nat. Dipt. I, p. 486; Tab. 

 XI, f 3 (1834 ; Dijit. Exot. II, 2, p. 10; Tab. I, f. 2. Philadelphia. 

 Mr. Bigot, in whose possession the typical specimen of Macquart's de- 

 scription now is, makes the following statement about it Annales Soc 

 Entom. de France, 1858, p. 590): „The head of this specimen is glued 

 on, and resembles that of Conops, while the body is that of an exotic 

 Microdon." AVe may with safety, therefore, strike out this genus and 

 species from among the number of existing forms. (Osten Sacken, Bull. 

 Buff. Soc. N. H., Nov. 1875.) 



Since writing the above, I have seen the specimen and can only con- 

 firm the statement. The body seems to belong to Microdon aurijix Wied.
