as broad as one-fourth the width of the head ; arista black, very 

 short pilose. Scutellum small, with only a pair of lateral small 

 bristly hairs. Halteres black. Ovipositor exserted. Wings

53. Plagiostenopterina eenea Wied. 1830. 



A common species in the Oriental Region. Known also from 

 Formosa. 



54. Plagiostenopterina calcarata Macq. 1843. 



Well distinguished by its beautiful shining blue coloring and 

 by the strong trochanteral spine of the male. 



55. Plagiostenopterina trivittata Walk. 1869. 



Distinguished by the color pattern of the thorax; the same aa 

 P. zonalis Rondani, from Borneo. Walker placed it originally 

 in Dacus. 



56. Elassogaster sepsoides Walk. 1861. 



Described from Amboina and Batchian, and as E. unimacu- 

 latus Kert. from New Guinea. Found also in Formosa. Its 

 similarity to Sepsis viduata Thoms. is very striking. 



57. Rivellia basilaris Wied. 1830. 



Described originally from Sumatra, and recently recorded 

 from Formosa. 



58. Rivellia fusca Thoms. 1869. 

 An endemic species.

A common species in the Orient. Known also from Formosa. 



62. Chaetodacus caudatus Fabr. 1805. 



Common in the Oriental Region. A specimen in this collec- 

 tion agrees with the description of the var. nubilus Hendel, from 

 Formosa, having the posterior cross-vein only shaded below, 

 but it has the brown spot at the apex of the femur. 



63. Chaetodacus cucurbitae Coq. 1899. 



The present material agrees with my specimens from India. 

 The allied synnephes Hendel, from Formosa, has four scutellar 

 bristles.
