WILLISTON: NEW DIPTERA. 65 



Bclimus muricatus. 



fEpibdtus miiricittes Ostcn Sacken, Western Diptora, 272. 



Female. Wholly deep black throughout, with black pile and deep 

 brown wings. Face and front wholly shining. First joint of the 

 antennae a little shorter than the third. Anterior part of the dorsum 

 of the thorax subopaque; the posterior part, the scutellum and the 

 abdomen very much shining. Wings deep brown; the interior of the 

 outer cells a little lighter colored. 



Length, 14 mm. 



Two specimens California, Washington; University of Kansas col- 

 lection. 



It is seen that I do not accept the genus Epibatcs Osten Sacken. 

 The sole differences now known to separate it from Ecliiniis are the 

 murication of the mesonotum and the denticulate costa, characters 

 found only in the male, as specimens of E. inagnus O. S. and E. 

 Sackciii Burgess prove. Furthermore, if the characters distinguishing 

 Epibates are accepted the name must give way to Thcvencmyia Bigot, 

 a species of which Bigot has recently described from Washington, 

 without showing wherein it differs from E. Sackeni. 



Eclimus sod alls, n. sp. 



Female. Front but little shining, clothed with long, black pile; on 

 the lower part, somewhat pollinose. First joint of the antennae 

 nearly as long as the third, clothed with black pile. Face moderately 

 shining, with black pile. Occiput with abundant, nearly yellow pile. 

 Thorax but little shining, clothed throughout with nearly white pile; 

 scutellum shining, with white pile; first four segments of the abdomen 

 with rather abudant white pile; that at the extremity black. Femora 

 with sparse black pile. Wings brown in the costal, subcostal and first 

 basal cells; a deep cloud on the anterior cross-vein: less distinct 

 clouds on the outer cross-veins, and at the proximal end of the second 

 submarginal cell. 



Length, 1 1-12 mm. 



One specimen, Washington, University of Kansas collection. 



Eclimus melanosus, n. sp. 



Female. Front, face and basal joint of the antennae with black 

 pile; occiput and the underside'of the head with white pile. Third 

 joint of the antennae broad, scarcely longer than the first joint. 

 Mesonotum opaque, with loose, nearly white, or yellowish white pile; 

 scutellum shining. Pleurae white pollinose. Abdomen opaque black, 

 the last segment shining; pile loose, white; on the hind margin of the 

 first five segments more recumbent and showing as narrow bands;
