 Ent. Z. Vol. I, p. 21. 



55. The paper by Gerstaecker referred to here is entitled: Beitrag 

 zur Kenntniss exotischer Stratiomyidcn, and is an important contribution 

 to the classification of this family. The name Euparyphus can stay, 

 although there is a much earlier genus Enparypha in the MoUusca, 

 1844. 



56 Compare Loew, Odontomyia, in the Linnaea Entomologica, 

 Vol. I, p. 467, a review of the european species. 



57. Odontomyia limbipennis. The label in Macquart's handwriting 

 in Mr. Bigot's collection bears America, with a query; the query is 

 omitted in the Dipt Exot. I doubt that this is a north american tpecies. 



58. Compare Stratiomys by Loew, in Linn. Ent., Vol. 1, p. 462. 

 Review of the european species. 



Also Gerstaecker, Linn. Ent. XI, p. 317, where some important 

 remarks on exotic species will be found. 



59. In Dr. Gerstaecker's article on exotic Stratiomyidae (Linn. Ent. 

 Vol. XI, 1857) the genus Cyphomyia is treated monographically and 

 with great completeness. He enumerates twenty four species. 



A Synoptic List of the known Cyphomyiae is given by Bigot, 

 Ann. Soc. Ent. 1875, p. 483. 



60. Clite'.kria. Compare Loew's remarks about this genus and 

 Epliippium, in his Bescl.r. Europ. Diptern, Vol. HI, p. 73. 



61. There is a Rondania Bigot i,Essai d'une Classific. 1853, Tipu- 

 lida), and a still earlier Bondania R. Desvoidy 1850, Muscida. 



62. A monograph of the european species of Nemotelus is given 

 by Loew, in the Linn. Ent., Vol. I. See also Loew, Beschr. Europ. 

 Dipt. II, p. 44, obs. 2. 



63. Compare Loew. Revision d. Europ. Paehygaster-Arten, in the 

 Zeitschr. f. Ges. Naturw. Vol XXXV; 1870. 



64. Compare: Osten Sacken, Prodrome of a Monograph of the 

 Tabanidae of the United Spates (in the Memoirs of the Boston Society 

 of Natural History, Vol. H, 1876, p. 365-897 and p. 421—479; and a 

 Supplement p. 555 — 560). 



65. Pangonia. Compare: Notice sur le genre Pangonie, by Macquart, 

 Ann. Soc. Ent. Fr. 1857, p. 429-438, Tab. XV; and Loew, Neue Dipt. 

 Beitr. VI, p. 23; 1859 (european species). 



Macquart, 1. c. says that the genus Pangonia was established by 

 Latreille, in the Bid. d'Hist. NatarelU of Deterville. I cannot now 

 verify this quotation; at any rate the publication cannot have been 

 earlier than 1802, because the dictionary bears the dates of 1802—1804. 



66. Silvius isabelLnus "Wiedemann, the type of which I have seen 

 in the Berlin Museum, is not a Silvius, but a Pangonia. It looks like 

 a very pale-colored Pangonia pigra and may be that very species. 



67. About the european species of Chrysops, compare: Loew, 

 Verb. Zool. Bot. Ges. 1858, p. 613—634. 



The knowledge of this genus and the porper method for the discri- 

 mination of the species date from this paper. Descriptions of earlier
