NOTES. 



J^Ievertheless , as Mr. Macquart's description is very unsatisfactory, 

 I prefer to retain the name which I gave to this species. 



79. Tabanus cheliopterus Rondani I have seen the original tj'pe 

 of the description, presei'ved in the Royal Museum in Turin. It is a 

 very much rubbed female specimen, which seems to belong to T. fronto. 

 Of the wliite abdominal triangles, not a vestige is left, which explains 

 their being omitted in the description. 



80. Tabanus imitans Walker. (Syn. of T. fnscopnndatus Macq.). 

 In order to understand Walker's description, it must be borne in mind 

 that the T. abdominalis, to whom he compares it, is not that species 

 at all, but the same T. fuscopmidniHS Macq. 



81. Tabrnus gracilis Wied. Wiedemann's description was drawn 

 from a single specimen, the hind legs of which were wanting. There 

 are two specimens in the Vienna Museum (^Winthem collection), one of 

 which answers this description. It is of the size and shape of my 

 T. lo}njit><, but more reddish, the wings more tinged with brownish etc. 

 The abdominal pattern is very much faded. It seems to be a species 

 which I do not know, but which is closely allied to my lonrfus. 



82. Tabanus lineola Macq. Dipt. Exot. I, 1, 146, 49 must be some 

 other species than Ihuola Fab 



83. Tabanus sulcifrons. The type, in Mr. Bigot's collection, is my 

 tcctns. As the description is sufficiently recognizable, I admit the 

 priority. Macquart has fulcifrons, which, of course, is a misprint. 



84. Tabanus turbidus. The type, now in Winthem's collection 

 has very ))ale-colored wings. 



85. Tabanus unicolor. The type in Mr. Bigot's collection is an 

 unrecognizable specimen , perhaps T. tener; however there is an earlier 

 T. unicolor Wied. from Brazil. Mr. Rondani (Archivio etc. Canestr. 

 Ill, fasc. I, 1863) proposed to call the species T. Jatcritius , instead of 

 nnicohr; but the species, as a hopelessly doubtful one, be better 

 cancelled. 



86. Tabanus var'.egatus Fab. The type in Fabricius collection, 

 from which Wiedemann's description was drawn, being probably de- 

 stroyed, this will remain a doubtful species. 1 he specimen in Winthem's 

 collection {not type) is T. fuf^copundatus Macq. It is very probable 

 that my interpretation of Wiedemann's description is the correct one. 



87. Tabanus marginalis Fab. Wiedemann says: ,,Die Art phrase 

 habe ich nach einem sehr schon erhaltenen Exemplare des Wiener 

 Museums verbessert etc." I looked for this specimen in the general 

 collection, in Vienna, but could not find it. In the Wiuthem collection 

 a specimen labelled marginalis Fab. var. and marked as type, is my 

 T. cerastes. It cannot well be the specimen described by Wiedemann, 

 because he would have noticed the peculiar structure of the antennae 

 (at present, these are broken in the specimen . At any rate the T. 

 marginalis of Fabricius is , and will remain a doubtful species , and be 

 better dropped. 



88. Tabanus quinquevittatus. In the Winthem collection (Vienna) 

 there is a (J and a !^ i^both mai'ked as types), from Savannah, and not
