XII. NOTES UPON THE GENUS LEUCOPHENGA MIK 

 (DIPTERA) WITH DESCRIPTIONS OF SOME NEW 

 SPECIES FROM SOUTH AMERICA, WEST AFRICA, 

 AND THE PHILIPPINE ISLANDS. 



By Hugo Kahl. 



The genus Leucophenga was established by Professor Mik^ for the 

 European Drosophila maculata Dufour^ and he felt justified in doing 

 so, because the costa reaches only to the apex of the third vein; he 

 does not mention anything about the chsetotaxy, but remarks: 

 "Schon Leon Dufour hielt die Art f iir den Typus einer eigenen Gatt- 

 ung." Dufour described the imago, puparium, and nymph^ and later 

 the larva.^ Schiner first separated the species of Drosophila into two 

 groups with reference to the length of the costa and includes in the 

 first group the single species Drosophila maculata Dufour with costa 

 reaching only to third vein.* In 1893 Professor Strobl discovered 

 another European species, a female from Styria, and named it Leuco- 

 phenga quinquemaculata^ and in his specific description he touches 

 upon the chaetotaxy as follows: " Beborstung des Thorax und Schild- 

 chens genau wie bei maculata; ebenfalls 2 Sternopleural. 4 Schild- 

 chenborsten, etc." Two sternopleural and four scutellar bristles 

 apparently belong to all the species of Drosophilince, at all events they 

 occur in all the species before me of the genera Stegana, Phorticaf 

 Drosophila, and Scaptomyza, in Drosophila amcena Loew'' and Droso- 

 phila procnemis Williston,^ in Zaprionus vittiger Coquillett^ and in

 Zaprionus villiger Coquillett from Lolodorf, Kamerun, taken Oct. 29 and Nov. i, 

 1913. by Rev. A. I. Good. There are three fronto-orbital bristles, of which the 

 proclinate and largest one is situated unusually far below the lower reclinate, which
