TACHINOPHYTO n. gen. 



Moderately small black species, with abdominal segments edged 

 with silvery at base. Belongs in Phytoinre. Head more or less tri- 

 angular in profile ; front somewhat prominent, fully one-third width 

 of head at vertex ( $ ), widening toward antennae, face wider still, 

 about one-half width of head ; frontal bristles in a single row, de- 

 scending about to base of third antennal joint, vertical bristles 

 strongest, next bristle of each row weak, third bristle nearly as strong 

 as vertical pair, all three pairs directed backward, the other bristles 

 weaker, directed inward and decussate ; two strong orbital bristles 

 directed strongly forward. Face receding, epistoma not prominent ; 

 facial depression nearly three-fifths width efface, wider below, rather 

 triangular in outline, shallow, with a slight median carina ; facial 

 ridges with several bristles above vibrissse, which do not extend over 

 one-third way up, constricted only a little below; sides of face mod- 

 erately wide, bare ; cheeks about one-fourth of eye-hight, more or 

 less hairy, with bristles on lower border ; vibrisste strong, well curved, 

 decussate, inserted a little above oral margin. Eyes nearly bare, 

 microscopically, sparsely hairy, descending considerably short of 

 vibrissse. Antennae inserted above a line drawn through middle of 

 eves, somewhat shorter than face, first joint short, second elongate, 

 third about twice as long as second, moderately narrow, rather con- 

 vex on front edge, posterior apical corner rounded ; arista long, 

 thickened on basal fourth, microscopically pubescent, distinctly 3- 

 jointed, first two joints short. Proboscis short, little more than half 

 as long as hight of head, fleshy, labella large; palpi nearly reaching 

 end of proboscis, club-shaped, well thickened toward tip. Thorax 

 hardly narrower than head ; scutellum with a strong, decussate apical 

 pair of macrochretse reaching about to base of third abdominal seg- 

 ment, two shorter lateral pairs, and a very weak subdiscal pair. Ab- 

 domen but little wider than thorax, rather oval in outline, slightly 

 vaulted, first segment not shortened ; n)acrochset8e rather stout, all
