NOTIPHILA 



1823. Fallen, Dipt. Suec. Hydromyz., 7. 



Here we have a genus not easily confused with any other. The 

 costa extends to, or only slightly beyond, the tip of the third 

 vein, never attaining the fourth. The middle tibiae have three 

 or four erect bristles on their extensor surfaces. The face is flat 

 or gently convex, at most but slightly prominent in profile. The 

 middle femora of some males are noticeably ciliate beneath. 



Three species are recognized from Costa Rica.

half. {Noiiphila) 2

 region; frons and mesonotum distinctly striped. (Agrolimna) . .frontalis 



2. Mesonotum distinctly striped, at least with a broad lateral stripe 4

3. Abdomen with two series of large, triangular spots, which attain apices and 



lateral margins of segments. (Cuba) fulvimana

This seems to be the representative species of the northern 

 neotropical coimtries. It may be best recognized b}' the broad 

 face, pale second antennal joint, broad face with one to three 

 well developed bristles each side and the immaculate, or at most 

 faintly vittate, mesonotum. The general color is ochreous; even 

 the browns and the dark areas are overcast with this color. The 

 females should not be confused with those of virgata, which have 

 the browns of the abdomen more or less shining and the meso- 

 notum distinctly vittate. 



The species was described from Cuba. It is represented by 

 fifty-eight specimens, collected by sweeping over mud at the 

 following localities: Alajuela, September 15; Bonnefil Farm, Rio 

 Surubres, October 21; Cartago, December 12 to May 17; Lagima, 

 near Cartago, February 26; El Alto, July 7; Filadelfia, Rio 

 Tempisque, January 18; Guacimo, May 6; Juan Vinas, July 30; 

 Peralta, August 7 and March 24; Turrucares, December 22.
