AUSTRO-MAL AY AN DIPTERA 459 



Trypeta quadrifera Wall!. {Helomyza) J. Pr. Lin. Soc. V, 

 246! (Dorei, N. Guinea). 



A c/* and a 9; Andai, iN. Guinea, 1872 {L. M. D' AlberUs) ; 

 Hatam, ibid. June 1875 (Beccari). 



The description agrees well ; Ilelom. optaiura Wk. 1. c. VIII, 

 116 (N. Guin.) is exceedingly like this species, and differs only 

 in the shape of the black spots of the abdomen. The large 

 scutellum bears six bristles , the arista is plumose , the frontal 

 bristles large and conspicuous ; there is a strong bristle on the 

 cheeks^ under the eye, on each side. 



Trypeta slellipennis Walker, J. Pr. Lin. Soc. IV, 159! (Ce- 

 lebes). 



Syn. Sophira punctifera Wk., J. Pr. Lin. Soc VI, 15 ! (Gilolo). 



Twelve d^ 9 specim., from Ternate and Kandari , Celebes , 

 April 1874 {Beccari). Although it is said in the description of 

 Sophira punciifera that the antennal arista is bare, it is distinc- 

 tly plumose in the typical specimen, which I have seen in the 

 Br. Mus. Scutellum with six bristles, third vein pubescent. Comes 

 nearest to the genus Eulrela Lw. 



Trypeta melaleuca Walk. J. Pr. Lin. Soc. VII , 238 ! (North 

 Ceram). 



Syn. Trypeta -Attilia Walk. List etc III, 1021 (China). 



One c/', two 9 , Kandari, Celebes, April 1874 (Beccari). 



M.'' W.'s description agrees well. I have the same species 

 from the Philippines (Prof. C. Semper). Tryp. quadrincisa Wied. 

 is very like this species , at least the specimens so determined 

 by Schiner in Vienna (Nicobar Islands) ; only the small inter- 

 mediate dot on the hind margin is absent. Schiner places it in 

 the genus Acidia, and I think he is right. 



Trypeta signifacies Walk. J. Pr. Lin. Soc. V, 165 ! (Amboina) 

 Male. 



One 9 , Ternate 1875 (Beccari).
