Arista plumose; three large orbitals, uppermost nearer to inner vertical than to lower- 

 most orbital; postverticals small; face not markedly carinate; vibrissae present; prescutel- 

 lars present; two dorsocentrals; one humeral; two notopleurals; two supra-alars; two 

 postalars; two scutellar pairs, posterior ones crossed; no propleural; auxiliary vein rudi- 

 mentary^; discal and second basal cells confluent; costa very weak or absent beyond apex 

 of third vein; preapicals on second and third tibiae. 



The type species is the European Drosophila maculata Dufour. This 

 species, Hke the two nearctic ones, breeds in fungi. This habit, while 

 usual, is not invariable in the group, as I have bred L. varia Walker from 

 tomatoes. 



The five synonyms given above all represent attempts to split the genus 

 into smaller groups, but all seem to me to be based on too slight differences 

 to warrant new generic names. The supposed generic characters and the 

 tj'^pe species follow: 



Oxyleucophenga Hendel: Wings distinctly pointed. Type, 0. undulala Hendel, from Peru. 

 Drosomyiella Hendel: Second orbital unusually large, third orbitals shghtly convergent. 



Type, Drosophila abbreviata de Meijere, from Java and Formosa. 

 Paraleucophenga Hendel: Arista pectinate. Type, P. iriseta Hendel, from Formosa. 

 Neoleucophenga Oldenberg (new name for Paraleucophenga Oldenberg, not Hendel) : Costa 



reaches apex of fourth vein. Type, Leucophenga quinquemaculata Strobl, from 



Europe. 



The following 45 species may be referred to the genus Leucophenga. 

 Those marked with an asterisk (*) are here referred to this genus for the 

 first time, so far as I know. All these except the types of Oxyleucophenga 

 and Paraleucophenga Hendel were originally described as species of Dro- 

 sophila. All have been referred to Leucophenga on the basis of the published 

 descriptions, except obscuripennis Loew. I have examined the type speci- 

 men of the latter species. The unstarred species described by de Meijere 

 and by Lamb were referred to Leucophenga not as a genus but as a subgenus 

 of Drosophila.
