120 STUDIES IN AMERICAN EPHYDRIDAE (dIPTERA) 



A series of female before me show a slight variation which 

 may prove to be worthy of note. The sternopleura, especially 

 the sutures, also the femora are blackish, and the wings are hya- 

 line with the cross veins faintly clouded. A male from the same 

 series, however, does not show these differences so I hesitate to 

 consider this form at present as a variety worthy of a name.

Paralimna brunneiceps new species 



This is hardly a variety of meridionalis although the parafac- 

 ials are narrow, much narrower than in that species. The con- 

 stant brown color of the face is, I think, of specific value. 



Description of both sexes. — Entire face between the parafacials and below the 

 foveae evenly dark browai. Parafacials very narrow, almost linear; cheeks 

 scarcely longer than third antennal joint. All the lighter areas darker than 

 usual except the foveae and abdomen; pleura brownish. Otherwise similar to 

 meridionalis. Length. — 3.5 to 4.4. mm. 



Type.—d^; Turrucares, Costa Rica, Dec. 22, 1909, (P P. Cal- 

 vert; sweeping over mud), [A. E. S. No. 6093]. Paratypes. — 

 2 9 ; topotypical.

 over mud), 3, [A. E. S.]; Bonnefil Farm, Rio Surubres, 800 ft. alt., Oct. 21, 

 1909, (Calvert; sweepings), 1, [A. E. S.]. 



Paralimna agryostoma new species 



The present species should not be confused with any other. 

 The white face, general olivaceous color and silvery antennal 

 spot will distinguish it. 



Description of both sexes. — The general (;olor inclining to olive-green instead 

 of brown, that is the grays and browns tinged with green, except the cinereous 

 occiput, pleura and venter. Frons mottled; the black orbital spot large 

 enroaching on the foveae, with minute white spot. Face and cheeks gray to 

 shining white, more or less yellowish tinged on hump. Second antennal joint 

 with distinct white spot above near apex. Mesonotum indistinctly irroratcd,
