FAM. EMPIDID/E 265 
vein not forked, pedicel ot the second and third veins arising at the middle of the first basal cell, discal 
cell complete and with three posterior veins (CAelipoda) or open apically and the fourth vein forked 
( PAyllodromia), anal cell subequal to the second basal cell or somewhat shorter, the anal crossvein curved 
outwardly, anal vein separate from the hind margin of the wing : calypteres with a few cilia. 
Nomenclature. Type species : by Macquart's original designation, mazftisba, Macquart 
(not Panzer') — vocatoría, Fallen (Pl. 8, Fig. 25). Coquillett (1903), would make minor, 
Macquart — melanocephala, Fabricius, the type, and in 1910 considered CAelifoda a synonym of Hemero- 
dromia, Rondani in 1856 designated melanocephala, Fabricius, as the type of PAyllodromia and vocatoria, 
Fallen as the type of Chiromantis. The next year Bigot founded Lefidomyia (not Lepidomyia, Loew (1864), 
a Syrphid, changed by Mik (1886), to Lepidostola), on the same melanocephala, as mantisba, Meigen. 
Thamnodromia, Mik, was a change of name for PAyllodromia, Zetterstedt (1837, not 1842), which was 
thought preoccupied by PAyllodromia, Serville (1839), The type of PAyllodromia thus becomes the type 
of Thamnodromia. | Litanomyia, Melander, with type mexicana, Wheeler and Melander, by Coquillett's 
designation, is not generically distinct from C/eelipoda. 
'The synonymy of these genera may be thus shown : 
Subgenus CAelipoda, Macquart, s. str. Type : vocatoria, Fallen. 
Chiromantis, Rondani. Type : vocatoria, Fallen. 
Litanomyia, Melander. Type : mexicana, Wheeler and Melander. 
Phyllodromia of the catalogues. 
Subgenus PAyllodromia, Zetterstedt. "Type: melanocephala, Fabricius. 
Chelipoda of the catalogues. 
Hemerodromia, Westwood and Coquillett, 1910. Type : melanocephala, Fabricius. 
Lepidomyia, Bigot. Type : melanocephala, Fabricius. 
Thamnodromia, Mik. Type : melanocephala, Fabricius. 
Vocatoria possesses a complete discal cell, while in melanocephala the discal cell is outwardly open; 
otherwise these species are structurally very much alike, certainly belonging to the same genus.  Bezzi 
has recently described a curious form from Formosa, which in its reduced chatotaxy and enlarged anal 
cell departs markedly from the other species of Caelifoda. This species, jiclipenmis, has here been 
removed to the recently erected genus, CepAalodromia, Becker. 
Geographical distribution. — Both of the subgenera occur in Europe and North America 
and CAelifoda occurs also in South America and Oceania.
