866 NOTES ON FRUIT-FLIKS, 



Dacus cucumis French. 



Journ. Agric. Victoria, May, 1907. 



French proposed this, as a varietal name of a fly, bred from 

 cucumbers imported into Victoria from North Queensland. I 

 submitted this with other species to Dr. Bezzi, of Turin, and Mr. 

 Coquillet, of Washington, who both consider it to be a good 

 species. 



This last year, a large number of specimens were obtained from 

 shipments of cucumbers condemned at the port of Sydney, which 

 had been grown in Mackay, Queensland. The distinctive 

 characters in which it differs from Dacus tryoni are, a somewhat 

 uniform lighter colour; a short yellow dorsal stripe down the 

 centre of the apical half of the thorax, but not reaching to the 

 basal margin of the scutellum; and four bristles on the apical 

 margin of the scutellum. 



In Dacus tryoni there is a row of four bristles along the apical 

 margin of the thorax, behind the scutellum, and only two bristles 

 on the apical margin of the scutellum. 



Dacus frenchi Frogg. 



This species was described from a specimen obtained from Mr. 

 0. French, Government Entomologist of Victoria, who bred it 

 from oranges, from New Caledonia. 



Among some fruit-flies sent to me by Dr. Roepke, of Java, 

 were four male specimens of an undetermined species, that 

 proved, on careful comparison with the type, to be the other .sex 

 of this species (the type being a female). The only difference is 

 in the shape of the abdomen, which is elongate and somewhat 

 spindle-shaped in the male. 



This fly, therefore, must have a very wide range, if found in 

 New Caledonia and Java. Dr. Roepke's specimens were bred 

 from the fruits of Artocarpus integrifoUa. 



Dacus kingii, n.sp. 



(J. Length, 8 mm.; 9. 11 mm. to tip of ovipositor. More slender 

 in form than usual; thorax narrow, truncate in front, broadest
