EUPROSOPIA METALLICA, new species 



Female. — Head testaceous yellow ; f rons deep black, the orbits nar- 

 rowly greyish white dusted, the dust carried downward on parafa- 

 cials to about the level of apex of third antennal segment; parafacials 

 dark brown, a black quadrate mark covering the area below eye from 

 in front of antennal fovea to level of hind margin of eye ; face cen- 

 trally undusted; occiput fuscous in center above, densely greyish 

 white dusted; antennae and aristae blackish brown; palpi black; 

 labrum shining black. Thorax black, mesonotum glossy dark blue- 

 green, castaneous on side behind suture, and with an angular patch 

 of whitish dust on each side in front of suture; pleura partly cov- 

 ered with dense whitish dust, most conspicuous on mesopleura and 

 sternopleura, the pteropleural hairs long and white behind, short 

 and dark in front; scutellum metallic blue-green. Abdominal dor- 

 sum concolorous with mesonotum, the fourth visible tergite broadly 

 castaneous or cupreous on each side; hairs on venter basally pale, 

 the others dark. Legs black, basal two-thirds of metatarsus of mid 

 and hind legs whitish yellow. Wings hyaline, with a number of 

 black spots and streaks at bases extending to apices of basal cells 

 and furcation of veins 2 and 3, a broad fascia of same color extending 

 from slightly before apex of subcosta to near apex of first vein along 

 the costa, inclosing three small hyaline marks near or on costa, cov- 

 ering the inner cross vein, and running slightlj^ diagonally to hind 

 margin where it is less intensely colored ; a similar fascia at about its 

 own width from the first one extends from the costa about midway 

 between apices of first and second veins to hind margin, incloses a 

 small hyaline mark on costa, covers the outer cross vein, and con- 

 nects with another fascia at hind margin which runs obliquely to 

 costa, forming with it a V-shaped mark, the inner margin of the 

 outer arm before apex of second vein, the outer margin of same 

 expanding to tip of wing and filling almost all of apex of the first 

 posterior cell, with a small hyaline spot in apex of submarginal cell, 

 and the outer lower outline more or less dentate; in addition to these 

 conspicuous fasciae, there is a small dark streak on the costa between 

 each of them, and some small spots in the anal region, while the 

 hind margin of the latter is also dark. Calyptrae whitish, with dark 

 margins. Knobs of halteres brown. 



Head about 1.75 as high as wide in front ; f rons over twice as long 

 as its width in front; inner verticals minute, directed outward, outer 

 pair of moderate length; antennae about as long as distance from 

 apex to mouth ; basal fifth of aristae with some hairs which are about 

 half as long as width of third antennal segment ; upper extremity of 

 facial carina not noticeably depressed nor glossy, rather distinctly
