 August 3d (J. M. Aldrich). 



ATROPHARIXTA u. gen. 



Black, shining species with much the facies of Jurinla, though 

 smaller. Belongs in Hystriciina?. Head nearly rectangular in pro- 

 file; front very prominent; front of male about one-third width of 

 head, of female considerably more than one-third ; frontal bristles 

 weak, not descending below base of antennae; vertical bristles strongest, 

 directed backward and inward, sometimes slightly decussate, other 

 bristles directed mostly forward, weak and sparse ; female with two 

 orbital bristles ; face somewhat receding, facial depression modei'ately 

 deep, epistoma rather prominent; facial ridges bare; sides of face 

 very wide, bare, except some short hairs on upper frontal portions ; 

 cheeks very wide, almost as wide as hight of eyes, bare except fringe 

 of bristles on lower border ; vibrissas inserted a little above oral 

 margin, but little longer than the bristles below them. Eyes bare. 

 Antennae considerably shorter than fece, second joint elongate, third 

 joint as long, or a little longer than the second, not widened ; arista 

 unusually short, not longer than third antennal joint, bare, moder- 

 ately thickened, distinctly 3-jointed, the second joint slightly elon- 

 gate. Proboscis about as long as hight of head, fleshy, labella de- 

 veloped ; palpi well developed, slender, somewhat thickened at tip. 

 Thorax about as wide as head ; scutellum with an apical decussate 

 pair of macrochsetae and four lateral pairs, the latter longer than the 

 apical pair. Abdomen wider than thorax, broad oval, first segment 

 somewhat shortened ; macrochaetse only marginal ; hypopygium of 

 male prominent. Legs moderately stout and bristly ; claws and 

 pulvilli of male elongate. Wings about as long as abdomen, without 

 costal spine, third vein not spined at base ; apical cell ending before 

 the tip of the wing, open ; fourth vein bent at an angle, with or 

 without extremely short stump of a vein at the bend ; posterior 

 cross-vein sinuate, nearer the bend of the fourth vein ; apical cross- 

 vein almost straight. Type, A. jurinoides n. sp. 



This genus much resembles a small Jarinia, but is at once distin- 

 guished by the very short arista, and the linear, not widened, third 

 antennal joint. 



Atropharisfa jurinoides n. sp. % . — Eyes dark browu ; front blackish, 

 silvery on the sides, the silvery area descending obliquely on the sides of face to 

 the lower margin of the eye, forming a semi-lunar marking in front of the eye;
