basal portion, the total length, including the style, being about 

 thrice the length of the first and second joints together. Thoi'ax 

 with a stout spine on each side, just before the base of the wings; 

 scutellum with two spines. Abdomen longer than, and about 

 equal in breadth to, the thoi'ax. Legs rather long. Wings with 

 the four, posterior veins complete, all arising from the discal cell. 



This remarkable genus agrees with Ephippium in having a 

 stout spine on each side of the thorax, but is distinguished from 

 that genus by the very different antennae. The form of the style 

 bears some resemblance to that of Hermetia, but Negritomyia is 

 distinguished from that genus by its thoracic spines.
