Dipterologische Studien IV. Ephydridae. 'ilb 



writer for natnes are two specimens of a liitherto undescribed form 

 allied to the Ephydridae, but differing from all of the known species 

 b}- the entire lack of long bristles, and by the unusually short an- 

 tennal arista. The absence of a spur on the second antennal Joint 

 and of bristles on the outer side of the tibiae, taken in connection 

 with the ha>ry eyes, would throw this form in the subfamily Hy- 

 drellina, but the entire absence of bristles, the unusually short an- 

 tennal arista and the short face, will necessitate the erection of a 

 new subfamily, for which the name Lipochaeti nae is proposed 

 (from the Greck Xm, without and /««r//, seta). The principal cha- 

 racters of this new form are as follows: 



Lipochaeta n. gen. 



Entire insecte destitute of long bristles. Head as broad as the 

 thorax, in profile longer than high; eyes protuberant, round, densely 

 short pilose; face scarcely one-eight as long as the front, clypeus 

 projecting nearly the length of the face, oral opening, one and one 

 — half times as wide as the front; cheeks at least one — half as 

 Wide as the eye-hight; antennae shorter than the transverse diameter 

 of either eye, bent outwardly and partly concealed in cavities in the 

 face; first Joint minute, the second broader than long, the third hemi- 

 spherical narrower than, but nearly aslong as the second; arista 

 dorsal bare, shorter than the third antennal Joint, unusually robust, 

 less than three times as long as broad; scutellum subconical, one- 

 fourth as long as the thorax. Abdomen elongate oval, nearly as 

 Wide as and about as long as the thorax, composed of five segments. 

 Legs slender, claws large, curved; pulvilli well developed; auxiliary 

 vein wanting, second basal cell wanting, bind cross-vein slightly more 

 than its own length from the tip of the fifth. Type: the following 

 species. 



-Lipochaeta Slossonae n. sp. 



Black, the halteres and tarsi yellow, densely whitish pollinose, 

 the front except next the eyes, dorsum of thorax and of scutellum 

 grayish brown pollinose. Wings whitish hyaline, veins brown, the 

 third and fourth strongly converging toward their tips. Length 

 2,5 millim. 



Punta Gorda, Florida. Two specimens from Mrs. Annie T. 

 Slosson, who writes that she took seven specimens which were 

 flying over mud. —
