Head, cf . Frons one-fourth width of head ; grey, yeUowish 

 grey or shghtly bkiish grey. A very wide frontal stripe appearing 

 from above almost velvet-black, thus leaving only very narrow^ eye- 

 margins. Generally, this black stripe has a greyish V-shaped piece cut 

 out of its upper end, which lighter space encloses the ocellar triangle, 

 which latter is small, and touches the absolute vertex ; and bears, 

 just above the lower ocellus, tw^o pairs of bristles (the lower pair 

 the larger). There are also 4 other pairs close together (all 6 pairs 

 forming one doul)le row) on the upper part of the triangle, the 

 u])permost pair being on the extreme vertex. Seen from below, the 

 black frontal stripe is invisible, the whole frons and face appearing 

 white, or yellowish white. Fronto-orbital bristles, about 15, the 

 upper part of the row not alwa3's placed uniformly. Two i)airs of 

 vertical bristles as usual. Ryes black, al)solutely l)arc. Antennae 

 blackish, 3rd joint more or less yellowish grey, 2nd joint with 

 several small l:>ri.stles and 1 or 2 long ones ; arista with 8-9 bristles 

 and minute pubescence on basal half above ; thickened at base, where 

 it is often yellowish. Face white or yellowi.sh white, covered with 

 close, microscopic tomentum. ]\Iouth oi)ening similar, with the 

 usual strong bristles on each side. Pal])i small, reddish yellow, with 

 a few short black bristles. Proboscis shining black, quite bare, 

 tapering from base to tip. Back of head generally more or less 

 bluish grey, with very short ])ul)escence. 



In the 9 the fronto-orbital bristles arc less strong and loss 

 regular, generally rather less in nunil)er, and on the upper i)art 

 of the frons there is a short extra row each side, placed nearer the 

 eye margin, sometimes also with additional irregularly placed small 

 bristles. In all other respects the 9 head is similar to that of the c^ .
