 Odontomyia bermudensis sp. nov. 



Female: This species is closely related to 0. cincta Oliv. and 

 might be considered by some only a variety, but the apparent con- 

 stancy of the seven specimens before me seems to warrant their 

 separation. The two principal characters which readily distinguish 

 this species are the conspicuous black stripes extending from the humeri 

 to the base of the wings, dividing the green lateral stripes of the thorax 

 from the green pleura, and the dark brown color of the larger vein, 

 this color also extending over the costal and marginal cells and the base 

 of the Wing. Minor characters are the greater amount of black on the 

 head, the black of the vertex being often connected with the large 

 black orbital spots of the front, from which extend narrow curved lines 

 to the frontal suture, and a narrow frontal stripe, which is also often 

 present. The black markings of the abdomen are much larger, covering 

 fully two thirds of the surface, while in 0. cincta the black rarely 

 exceeds one half. Six of the specimens have a dark yellow scutellum, 

 but this may be a discoloration, as it occasionally appears in 0. cincta. 

 Length 10 to 12mm. 



Six specimens. May 9 and 11 (Jones); one specimen, July 26 {Kin-
