228 NOTES. 



.Nevertheless, as Mr. Macquarfs 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 type 

 of the description, preserved in the Royal Museum in Turin. It is a 

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

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

 their being omitted in the description. 



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

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

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

 at all, but the same T. fuKcopunctatus Macq. 



81. Tab?nus 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. kiifjitfi, 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 longns. 



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

 other species than lineola Fab. 



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

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

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



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

 has very pale-colored wings. 



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

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

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

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

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

 cancelled. 



86. Tabanus variegatus Fab. The type in Fabricius collection, 

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

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

 collection (not type) is T. fuKcoptmctatus Macq. It is very probable 

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



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

 habe ich nach einem sehr schon erhaltenen Exemplars des Wiener 

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

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

 a specimen labelled marghtctlis Fab. vai: 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. 

 mcn-</iii(tlis of Fabricius is, and will remain a doubtful species, and be 

 better dropped. 



Tabanus quinquevittatus. In the Winthem collection (Vienna) 

 there is a $ and a (both marked as typcs\ from Savannah, and not
