AUSTRO-MALAYAN DIPTERA 439 



Volucella trifasciata Wied. Auss. Zw. II, 196 (Java). 

 One 9; Buitenzorg, Java (Ferrari). 

 Agrees well with the description. 



Graplomyza gibbula Walk. {Barytocera) , J. Pr. Lin. Soc. IV, 

 120 (Celebes). 



Three spec. ; Kandari, Celebes, April 1874 (Beccari). 



Is very like Gr. brevirostris Wied.^ but differs in the color of 

 the femora ; Gr. meliponaeformis Dol. (Amboina) has a yellow 

 scutellum, with a black margin. 



Graplomyza spec. 



One 9, Java 1874 (Beccari). 



Resembles G. ventralis Wied. Auss. Zw. IT, 207 (Java) very 

 much, only the black coloring on the 3^ and 4'^ abdominal 

 segments is more extended, and the femora, except the extreme 

 end, are black. In Leiden , where I saw Wiedemann's type, 

 there were two or three closely allied forms, and it may be 

 that they are all varieties of ventralis. 



Graptomyza lineata n. sp. 



One 9, Ternate 1875 (Beccari). 



Of the same type with Graptom. longirostris Wied. , the sta- 

 ture being elongated, the 3*^ antennal joint long and narrow, 

 the body marked with longitudinal Hues: only the proboscis is 

 not exerted, as in Wiedemann's figure. 



Body and legs altogether pale yellow ; rostrum with a little 

 brownish above ; antennae reddish , upper edge of the third 

 joint brown ; arista yellow, brownish towards the tip. Thorax: 

 a longitudinal brown line, placed, one on each side, immedia- 

 tely inside of the humeral callus ; they become evanescent before 

 reaching the scutellum ; abdomen with three well-marked brown 

 longitudinal stripes, reaching to the tip ; halteres and legs yel- 

 low, tips of tarsi brownish. Wings hyaline (very much damaged 

 • and soiled). 



Although the specimen is damaged, perhaps even immature.
