8. DESCRIPTION OF THE SPECIES. 



Family TRYPANEIDAE. 



I. Subfamily Dacinae. 



I. Leptoxyda, Macquart. 



Macquart, Hist. Nat. des Ins. Dipt., ii, 452. 2, (1835). 



As stated above I include in this genus the species of Dacus s. I. which have 

 neither prsc. nor anterior sa. bristle; these differ from Dacus s. str. in having an 

 elongated body and a cylindrical borer in the female. The type of the genus is L. 

 testacea, Macquart, /. c, which seems to be the same as Dacus longistylus of Wiede- 

 mann, 1830, or at least a closely allied species. Macquart in 1843 has emended his 

 own name to Leptoxys, which is perhaps orthographically better; but at the same 

 time he has employed it in a different sense, including some Neotropical species which 

 are now placed in Anastrepha ; and as I find in Scudder's " Universal index ", p. 173, 

 that this name is preoccupied by Rafinesque in the Mollusca, I prefer to use here the 

 original spelling. The genus, as at present known, is exclusively Ethiopian, some 

 species being, however, represented in Egypt. 



I. Leptoxyda sp. near longistyla, Wiedemann. 

 (PI. viii, fig. I.) 

 There are in the collection three females from Karachi {Cumming), 3o-vii-89, 

 ~ff"-~fl~' which undoubtedly belong to this genus, and are very closely allied to 

 longistylus , differing only in having the yellow marks less distinct, and the ovipositor 

 a little shorter. Unfortunately they are too much damaged for description. This 

 is probably an imported African species. 



2. Bactrocera, Guérin-Ménéville.

 tion appeared only in Livr. xxviii, 1838).

I adopt this name for the Oriental (and Australian) species of Dacus s. I. which 

 have a pair of prsc. and an anterior sa. ; practically this genus will contain all the 

 true species of Dacus as yet known from the Orient. As the type of the genus I take 

 Musca ferruginea of Fabricius, 1794, and also Dacus umbrosus, Fabricius, 1805, with 

 which Bactrocera longicornis of Guérin is perhaps synonymous. Some species of this
