Tribe CAKCELnNI. 

 GYMNOCARCELIA, new genus. 



The characters of this genus are indicated in the description of 

 the species. 



Genotype. — Gymnocarcelia ricinorum, new species. 



GYMNOCARCELIA RICINORUM, new species. 



This name is proposed for Sturmia alhifrons Coquillett 1897.' The 

 species is doubtfully the same as Tachina alhifrons Walker 1856,^ from 

 the United States, which name in any event is preoccupied by TacMna 

 alhifrons Walker 1837/ from South America. 



The genus is at once distinguished from all other CarceUini by the 



quite bare eyes. The type-specimens were reared by Mr. Max Blis- 



liuk, jr., at Allapata, Florida, from Apantesia pliyllira Drury found 



feeding on Ricinus communis. The species has been reared from 



various Arctians.

Clypeus well sunken. Epistoma moderately short, a little warped. 

 Faciaha bare. Proboscis short, labella large. Palpi stout, bowed, 

 widened. Third antennal joint about three times the rather long 

 second. Arista long, slender, bare. Eyes thickly pilose. Male 

 vertex rather over one-fifth head width. Three frontals below base 

 of antennae. Ocellars strong. Parafacialia narrow, bare. Cheeks 

 about one-eighth eye length. Tvvo sternopleurals ; three postin- 

 traalars, preacrostichals, postacrostichals, and lateral scutellars;
