Fallen), mMicropeza; also, Musca cothurnata and petronella, 

 of Linnaeus, to which Calobafa is now restricted. He has 

 removed Musca vibrans, of Linnseus, (placed with Micropcza 

 in the Hist. Nat. des Crust. &c.) to Tephritis, which he 

 places next to the other genus, its natural situation, if Musca 

 cynipsea and vibrans are taken as their respective types, 

 though the affinities of some species included in the two 

 genera are very remote. He has formed nearly the same 

 arrangement in the Regne Animal, but in the Families 

 Naturelles it is more artificial ; as Dictya and Dacus are 

 placed between Tephritis and Micropeza, constituting with 

 Platystoma, his Carpomyzce, which, with his DolichocercCy 

 and a part of his Gonocephalce, form the Ortalides of Fallen, 

 containing, among other genera, Ortalis and Sepsis, Musca 

 vibrans^, Tephritis cerasi and Syngenesice, &c. being the types 

 of the former; — Musca cynipsea and punctum, of the latter 

 genus ; while Tephritis cardui, solstitialis, radiata, &c., and 

 Micropeza corrigiolata, remain in the same genera. The 

 last-mentioned species is placed with Calobata, by Latreille, 

 in the Diet, de I' Hist. Nat., while Musca cy?iipsea and 

 punctum are left under Micropeza. R. Desvoidy follows this 

 arrangement, and makes a new genus ( Phantasma) of Musca 

 Jiliformis, which, with Calobata, Nerins, Sepsis, &c. he calls 

 Thelidomydce , the 2d tribe of his 5th gens, Phytomydce. 

 In the new edition of the Regne Animal, Latreille places the 

 following genera under Carpomyzce. 1 . Diopsis, Lat. 2. Ce- 

 phalia, Meig. 3. Sepsis, Fall. 4. Ortalis, Fall. 5. Tetanops, 

 Meig. 6. Tephritis, Lat. 7. Platystoma, Meig.
