Dtpterologische Studien IV. Ephydridae. 27b 



writer for names are two specimens of a hitherto undescribed form 

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

 by the entire lack of long bristles, and by thc 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 hairy eyes, would tlirow 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 

 (frorn the Greck /.m. without and yaiTi^, seta). The principal cha- 

 racters of this new form are as follows: 



L%i)ochaeta 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 tinies as wide us the front; cheeks at least one — half as 

 Wide as the eye-hight; antennae shorter than the transversa diaraeter 

 of either eye, beut 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 as long 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 live 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 tifth. Type: the following 

 species. 



Lipochaeta Slossonae n. sp 



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

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

 gra)ish 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 writcs that she took seven specimens which were 

 flying over mud. —
