Puliciphora flava new species 



Male.- — Yellow. Abdomen cltirk brown. Wings clear, veins brown. 

 Halteres yellow. 



Frons weakly bristled, the surface with yellow hairs; arista pubesceat, 

 longer than width of frons; palpi of good size, distinctly bristled. Scutel- 

 lum with 2 bristles. Hypopygium large and protruding. Legs strong and 

 long; mid and hind tibial spurs verym.inute. Wings with costa to dis- 

 tinctly beyond the middle; first costal division half as long as second, costal 

 fringe shorter than diameter of costal vein; fourth vein almost straight, 

 seventh vein distinct. Length, 1 mm. 



Holotype. — -Rio Siquiarcs, Turrucares, August 14, 1909, 2200 feet 

 altitude. Ty-pe No. 6051. 



AGROMYZIDAE 

 Agromyza meridionalis new species 



Female. — Shining black. Head yellow, only the ocellar rc.?ion, orbits 

 posteriorly, and back of head black; arista darkened. Me -'^iiotum with 

 lateral margins broadly lemon yellow, the upper margins of pleura and 

 central vertical suture narrowly margined with same color. Legs shining 

 black, only the fore knees narrowly yellowish. Wings slightly grayish, 

 veins black. Squamae and halteres lemon yellow. 



P>ons narrow, distinctly narrower than width of either eye; four orbital 

 bristles present; orbits bare except for the large bristles; antennae of mod- 

 erate size, second joint with distinct dorsal bristle, third joint rounded in 

 front; arista tapering at base, slightly pubescent, its length equal to from its 

 ba.se to vertex; cheek at posterior margin slightly more than equal to width 

 of third antenna! joint, marginal hairs distinct; vibrissa slightly differenti- 

 ated; eyes higher than long, bare. Mesonotum with 2 distinct pairs of 

 dorso-central bristles, the disk covered with numerous short setulae, the 

 pair of bristles usually present between the posterior dorso-centrals not 

 differentiated from the other setulae. Legs stout; the normal pair of bris- 

 tles on posterior surface of mid tibiae very weak. Wings with costa to 

 fourth vein; veins 3-4 divergent; fourth vein ending at wing tip; inner cross 

 vein at slightly beyond middle of discal cell; outer cross vein at about its 

 own length from inner and directly below end of first vein; last section of 

 fifth vein rather more than twice as long as penultimate section. Length, 

 L.5 mm. 



Holotype. — 9 , Alajuela, September 15, 1909, taken by sweep- 

 ing at an altitude of 3100 feet. Type No. 6052. 



Paratypes. — 3 specimens with same data. 



This species belongs to the same group as plaiyptcra Thomson, 

 but the color of the antennae, long arista, and bristUng of the 

 mesonotum readily separate it from that species. In its stout 

 build and black legs, as well as the wing venation it most closel}' 

 resembles platyptera amongst the American species.
