 punctiform well defined, a broad furrow from them to the supracly- 

 peal tubercle ; antennal furrows and ocellar basin obsolete ; postocel- 

 lar area defined laterally by elongate foveae ; postocellar furrow 

 obsolete ; postocellar line distinctly longer than the ocellocular line ; 

 third antennal joint about twice as long as the fourth ; stigma nearly 

 parallel-sided, truncate apically ; transverse radius received by the 

 radius beyond the third transverse cubitus ; transverse median some- 

 what basad to the middle of cell ; sheath straight above, tapering be-

WALDHEIMIA MELANOCEPHALA, new species 



Colored like Waldheimia ochra (Norton), to which it is closely 

 related, but may be separated from ochra by the smaller size and 

 sharply defined middle foveae. 



Male. — Length 6 mm. Labrum short, narrowly rounded apically ; 

 clypeus truncate, lateral angles rounded, at about the middle with a 

 transverse depressed area ; supraclypeal foveae confluent with the 

 antennal f ovese ; supraclypeal area rectangular in outline, convex, 

 more strongly so dorsally ; middle fovea oval in outline, well defined ; 

 antennal foveae confluent with the punctiform frontal foveas which 

 are on a line with the middle fovea ; antennal furrows obsolete ; 

 ocellar basin U-shaped open below ; postocellar area defined laterally 

 by elongate foveae ; postocellar furrow wanting ; postocellar line sub- 

 equal with the ocellocciptal line, but distinctly shorter than the ocell- 

 ocular ; stigma nearly parallel-sided, obliquely truncate apically ; 

 transverse median near the middle of cell ; hypopygidium long, 

 broadly rounded apically. Rufo-testaceous ; head (except the pallid 

 clypeus, labrum, mandibles and palpi), antennae, tibiae, tarsi, and 

 cochlearium black. Wings blackish ; venation blackish.
