150 DIPTERA OF NORTH AMERICA. [PART III. 



middle with a punctiform black dot; 1 finally, in the third cell, not 

 far beyond the fifth longitudinal vein, there are two successive 

 punctiform blackish spots ; the small crossvein is in the middle 

 of the discal cell ; the posterior crossvein is straight. 



Hab. Cuba (Gundlach). 



Observation. — The "accurate knowledge which Wiedemann had 

 of Fabricius's collection enables us to admit his authority as to 

 the synonymy of Dacus obtusus Fab. with Musca stigma Fab. 

 Wiedemann had a large number of specimens of Musca stigma 

 (which he placed in the genus Ulidia) for comparison, and it is 

 upon the ground of this comparison that he affirmed that the 

 presence or absence of a pale spot upon the black border of the 

 costa does not constitute a specific character. We can therefore 

 safely accept the synonymy of Musca stigma Fab. with Noto- 

 gramma cimiciformis Loew, the latter being the variety in which 

 the pale spot is wanting. 



Gen. IV. EUPHARA Loew. 



Charact. — Front of an equal, moderate breadth ; scrobiculate, coarsely 



hairy. 

 Antennce almost more than of medium length; third joint elongated, 



with a thin, bare arista. 

 Face excavated ; clypeus projecting. 

 Thorax with bristles on its hind part only ; scutellum convex, with four 



bristles. 

 Wings: Posterior angle of the anal cell drawn out in a point ; the last 



section of the fourth longitudinal vein parallel to the third ; the 



small crossvein rather approximate to the posterior crossvein ; the 



latter perpendicular. 



The principal characters which distinguish this genus from the 

 following one, to which it stands nearest, are the shorter and not 

 attenuated stigma and the parallelism of the third and fourth 

 longitudinal veins. Moreover, all the species of this genus seem 

 to have black crossbands on the wings, while in those of the next 

 following genus only the costal cell, the stigma, and the apex of 

 the wing are blackened. The typical species is Ceroxys coerulea 

 Macq. (Dipt. Exot. Suppl. Ill, p. 62, Tab. VII, f. 6), from 

 Brazil, again described by me as Euphara coerulea (Berl. Ent. 



1 It is inadvertently omitted in the figure ; the spots in the next cell 

 likewise are but very feebly marked.
