before the origin of Rs; Sd very far from the tip of Sci, the latter alone being 

 longer than the sector; Rs rather short, about one-half longer than the basal 

 deflection of Ri+i] cell 1st Mi closed, short, about equal to that portion of 

 vein Cui beyond it; basal deflection of Cui at or just beyond the fork of M. 

 Abdominal tergites black, the caudal half of the segments reddish; ster- 

 nites similar but with the black markings even more restricted; terminal 

 abdominal segments and the hypopygium black. Male hypopygium with 

 the ninth tergite gently concave across the posterior margin, the lateral 

 angles not produced; ventral pleural appendage fleshy, tapering to the nar- 

 row, subacute apex; dorsal pleural appendage a curved, chitinized hook with 

 the apex acute.

Dicranomyia pseudomorio new species 



General coloration shiny black, the anterior part of the vertex and the 

 pleura silvery pruinose; fore femora blackish, yellow at the base; wings nar- 

 row, with a strong browTi tinge, Sci long, about half the length of the long 

 sector, cell 1st M-2 narrow; abdomen black, the tergites indistinctly, the ster- 

 nites distinctly, banded with reddish; male hypopygium with the dorsal 

 pleural appendage a flattened pale arm that is expanded at the tip into a 

 hatchet-shaped blade. 



Male. — Length, 6.6 mm.; wing, 7 mm. 



Rostrum reddish brown. Antennae dark brownish black throughout. 

 The anterior j^art of the vertex brilliantly silvery. 



Thorax and legs as in D. submorio, but the fore femora blackish except the 

 bases, which are yellow; tibiae and tarsi blackish brown. Wings much nar- 

 rower than in D. submorio, with a strong brownish tinge, the stigma more 

 oval in outline and not so deeply colored. Venation: Sci ending slightly 

 beyond the origin of the sector, Sd removed from the tip of Sd, the latter 

 alone being less than half the length of the sector; Rs long, indistinctly spurred 

 at the origin, more than twice the length of the basal deflection of Rt+b] 

 cell 1st Mi closed, narrow, longer than Cui beyond it. 



Abdominal tergites deep black, the basal segments with the caudal margin 

 indistinctly reddish; sternites similar but with almost the posterior half of 

 the segments reddish. Male hypopygium black, cons icuously different in 

 structure from that of D. submorio; the lateral angles of the ninth tergite 

 are produced caudad into slender arms which bear a few short hairs at the tips; 

 pleurites stout, the inner face produced into a conspicuous arm which is ex- 

 panded into a head at its distal end; ventral pleural appendage stout, the 

 inner face produced into a point, so the whole appendage suggests the head 

 and beak of a bird, at the base of the beak-like portion is a slightly raised 

 papilla which bears a long, hyaline peg-like organ; dorsal pleural appendage 

 slender, flattened-cylindrical; slightly curved, at its outer end expanded into a 

 hatchet-shaped blackened blade.
