The expression of the description: ,,three whitish stripes" does not 

 answer, as the corresponding stripes in my specimen are reddish; the 

 abdomen is altogether red, and not „black above, at the base". 

 Dacus cylindricus v. d. Wulp, Tijdschr. etc. XXIII, Tab. XI, f. 5 

 (Java) also agrees with my specimen remarkably well; the differences 

 are : the brown oral border is divided into two distincts spots ; there is 

 no black spot on the occiput; the scutellum has a black triangle in 

 the middle, and not a black base only: the first abdominal segraent 

 is red, like the rest of the abdomen and not black. Are these different 

 species or varieties only? It is impossible to decide such questions 

 without the actual comparison of specimens. The same remark applies 

 Ädrama selecta and the synonymy adduced by me in th.e Enumer. 

 etc. p. 91. 



Rivellia fusca (Syn. Herina fusca Thomson, Eng. R. 575; 

 ManiUa). The yellow spots at the base^ of the abdomen are invisible 

 in some specimens. There is some obscurity in the description of the 

 design on the wings; (nervus humeralis?) — Ten specimens. 



NB. This is a true Rivellia in the sense of Loew , Monogr. III, 

 p. 87; 1. c. p. 44, at the bottom. Dr. Loew mentions the occurence of 

 Rivelliae in South-Eastern Asia, and says that they differ in having the 

 3*^ Joint of the antennae a little shorter; I do not perceive this difFerence. 



Stenopterina. 



From notes, taken in different collections, as well as from descrip- 

 tions, I have drawn up the foUowing table of the species from the 

 Malay ArchipelagoJ, which may be referred to the genus Stenopterina 

 in Loew's sense. At present, I have only specimens of S. calcarata, 

 eques, aenea (?). chalybea and didyma before me, and therefore cannot 

 verify all the Statements of this table. 



I. Scutellum with four bristles; tip of the first vein nearly opposite 

 the posterior crossvein; third and fourth veins converging. 

 In the $ a large spine on the bind trochanters. 



Metallic blue, with a brown margin on the costa, and in- 



fuscated crossveins calcarata Macq. 



(D. E. IL 3, 207.) 

 • Hind trochanters in the $ not spinöse. 



First basal cell brown; small crossvein distinctly oblique. 



The brown of the first basal cell stops short at the 

 anterior crossvein . , . . aenea Wied.
