Head black , with a gray pollen and black pile ; scapus of 

 antennae black, flagellum brownish-yellow. Thorax of a rather 

 uniform, saturate , dark orange-red , opaque. Halteres and legs 

 brown. Abdomen black , moderately shining , incisures opaque ; 

 last segment and ovipositor reddish. Wings of a uniform brown

 spot in the middle , between the first and the fifth vein (the 

 latter it does not touch) and immediately before the bifurcation 

 of the second vein ; the extreme tip of the wing also white. 

 The crossvein at the base of the 3*^ post. c. is placed obliquely ; 

 the great crossvein is in a hne with it. The tip of the auxiliary

Hah. Mt. Singalang, Sumatra, July 1878 (Beccari). One 

 female. 



RHYPHIDAE. 



Rhyphus sp. One specim., Sorong, N. Guinea, May 1872 

 (D'Albertis). 



This is the first Rhyphus recorded from the Archipelago ; 

 species have been described however from New Zealand and 

 Tasmania. The specimen (in very bad condition) does not seem 

 to have anything to distinguish it from the ordinary type of 

 the genus. 



XYLOPH AGID AE . 



Subula inamoena Walk. {Solva) , J. Pr. Lin. Soc. IV , 98 ! 

 (Celebes). 



Two 9, Kandari, Celebes, April 1874 (Beccari). 



The type has the abdomen black above with yellow incisures ; 

 tip of the antennae also black ; nevertheless it is very probably 

 the same species. 



NB. There is no necessity for a new genus Solva Wk. ; it 

 is simply a Subula, closely resembling in structure and coloring
