of a very distinct thoracic collar. The species is wanting in the 

 synopses given by me in my papers on the genus, but it is 

 easily known from any other by the broad blackish band on the 

 wings. 



22. Syrphus nectarinus Wied. 1830. 



This species is only an oriental variety of the common S. 

 balteatus DeG. 



23. Baccha pulchrifrons Aust. 1893. 



A distinct species previously known only from Ceylon and 

 Java. 



24. Baccha purpuricolor Walk. 1859. 



Seems to be a common species. Known before from Key 

 Island and Mysol. — 



25. Graptomyza brevirostris Wied. 1820. 



Formerly known from Java and the Nicobar Islands. A well 

 differentiated species, new for the Philippines. 



26. Megaspis errans Farb. 1787, 



A common species in the Oriental Region, 



27. Syritta orientalis Macq, 1842. 

 Formerly known only from India and Java. 



28. Eumerus flavicinctus Meij. 



Described from Java. Easily distinguished by the yellow 

 scutellar margin. It seems to me very probable that E. figurans 

 Walk, from Celebes is the same species, 



29. Eumerus bimaculatus Dol, 1858. 



A species described from Amboina, well distinguished by the 

 coloration of the abdomen. The enigmatical Citibaeus aurata 

 Walk, from Borneo seems to be an allied form. 



30. Prosena pectoralis Walk. 



Seems to be a common species. Formerly recorded only from 

 New Guinea. 



31. Stilbomyia fulgida Big. 1859. 



A very fine species, originally from Celebes, and new to the 

 Philippines. From Formosa I have received the allied S. fus- 

 cipennis Fabr. 



32. Lucilia fortunata Walk. 1860. 



Corresponds very well with the description of the type from 

 Celebes, and is a true Lucilia.
