describing. E. obscurata Wk., 1. c. V. 239 (N. Guin.), if not the 

 same species, must be closely allied. I have not examined them 

 carefully in the Brit. Mus. 



Eristalis multifarius Walk. Ins. Saund. Dipt. 248 ! (East- 

 Indies). 



One 9, Buitenzorg^ Java, 1875 (Ferrari). 



As I have seen the type in the Br. Mus. I have little doubt 

 that the specimen is a darker variety of the same species. The 

 third abdominal segment is occupied by a large black spot, which 

 leaves only a pale yellow hind margin, and a reddish-yellow 

 triangle in each of the anterior corners; the fourth segment is 

 altogether black, except the yellow hind margin ; the four front 

 legs are black, except the proximal half of the tibiae and the 

 root of the tarsi; proximal half of the hind femora ferruginous; 

 a dark reddish ring in the middle of the hind tibiae. Wings 

 strongly tinged with brownish-yellow, except the distal third, 

 which is hyaline. The yellow stripes of the thorax are rubbed 

 off in my specimen. 



Eristalis muscoides Walk. J. Pr. Lin. Soc. Ill, 96 ! (Aru Isl.'^O. 



One c/", Amboina 1873 (Beccari). 



The description agrees tolerably well. In the Brit. Mus. there 

 are two specimens , both with Walker's label ; one of them 

 resembles mine in the pattern of the abdomen and the plumose 

 antennae ; the other is a different species. Erisl. inscriplus Dol. 

 resembles this species very much, but has a bare arista and the 

 intermediate black spot on segments 3 and 4 is round, instead 

 of wedgeshaped. E. postscriptus Walk., 1. c. VII, 210 seems to 

 be the same as inscrvptus ; however, I have not compared the 

 types. 



Solenaspis nov. gen. 



Allied to Eristalis and Pier optila Lw. (Plagiocera Macq.), but 

 easily distinguished by the shape of its scutellum, by its eyes,
