SYSTEMATIC ACCOUNT. 65 
(A. L. Melander); Nelson (A. L. Melander), Kaslo (R. P. Currie), British 
Columbia. Recorded in Europe from the Faroe, Canary, and Madeira 
Islands to Sweden, Austria, Egypt, and Corsica. 
Scaptomyza vittata Coquillett. 1895. Proc. Acad. Nat. Sci. Phila. 47 (as Drosophila). 
Specimens examined: Biscayne Bay, Florida (Mrs. Slosson); Herradura 
(C. W. Metz), Santiago de las Vegas, Cuba; Yallahas Valley, Jamaica 
(Amer. Mus. Nat. Hist. coll.); San Jose, Costa Rica. Coquillett recorded 
the species from Porto Rico. Ihave seen the specimen in the U.S. National 
Museum, and am unable to convince myself that it is the same species, 
though it may well be so. 
I have also seen specimens of Scaptomyza from Peru and from Argentina. 
The latter at least were not S. vittata. Czerny (1903, Wien. ent. Zeit., 22) 
has seen the genus from Mexico. 
Drosophila Fallén. 1823. Dipt. Suec. Geomyz., 2, 4. 
Arista plumose; vibrisse and ocellars present; three orbitals, lowermost proclinate, 
upper two reclinate, middle one smaller than the others (second one placed a trifle below 
the third in D. alabamensis); postverticals large (missing in D. dubia); one or more hu- 
merals; one presutural; two notopleurals; two supra-alars; two postalars; one to three 
sternopleurals; mesopleurzee bare; two dorsocentrals (one in D. superba); prescutellars 
usually absent (present in D. sigmoides, D. flore, and species similar to each, represented by 
large hairs in D. repleta and other forms); two pairs of scutellars, posterior ones crossed; 
disk of scutellum bare; costa twice broken, reaches apex of fourth vein; two small bristles 
just before distal costal break (one in D. immigrans); discal and second basal cells con- 
fluent; anal cell present, often incomplete; preapicals evident at least on third tibiex; 
acrostichal hairs in six or more rows in front of transverse suture (four in D. opaca), four 
or more between the anterior dorsocentral bristles. 
The name Drosophila (Greek; dpécos, dew, and ¢idn, lover) means ‘‘dew- 
lover.” This is apparently the reason for the German name ‘‘Taufliege.”’ 
These names are purely fanciful, as the flies are not in any special way dew 
frequenters. ‘There seems to be no corresponding English term. In Eng- 
lish the names fruit fly, pomace fly, sour fly, and vinegar fly are sometimes 
used. Fruit fly is not a desirable term, as it is commonly restricted to the 
Trypetine, a very different subfamily, many of the larve of which feed on 
growing fruit. Pomace fly and vinegar fly both imply a very much narrower 
range of normal food habit than actually occurs. The technical name, 
Drosophila, has already become established in biological literature, so that 
it seems desirable to use it for the common as well as the scientific name. 
Many of the best-known genera of Acalyptere were established by Fallén 
in his “Diptera Suecize’”’—e. g., Sciomyza, Lonchea, Sapromyza, Sepsis, 
Piophila, Notiphila, Psilopa, Ephydra, Agromyza. Among these was 
Drosophila. This genus was described for the following twelve Swedish 
species, all described as new except one. The present status of those 
species no longer considered to belong to Drosophila is also given. 
D. curvipennis Fallén (to Stegana). D. tristis Fallén. 
D. variegata Fallén (to Phortica = Stegana). D. fusculaFallén (to Diastata—Geomyzinz). 
D. funebris Fabricius. D. cinerella Fallén. 
D. fenestrarum Fallén. D. flava Fallén (to Scaptomyza). 
D. transversa Fallén. D. graminum Fallén (to Scaptomyza). 
D. obscura Fallén. D. glabra Fallén (to Camilla). 
The third of these, Musca funebris Fabricius, was designated by Curtis 
(1833, Brit. Ent., p. 473) as the type species. 
Table 8 shows approximately the number of described species that may 
be taken as probably valid members of the genus. All those described by 
Walker and by Hutton have been omitted unless recognized later by other
