 " Cinerea, lutescenti-pilosa, pedibus luteis ; antennarum

{Redescription .) 



Head, c . Eyes sub-contiguous ; the frons for a short distance 

 being extremely narrow, the actual width var^'ing slightly in 

 different specimens. \'ertical triangle only moderately wider ; 

 the frons below its narrowest part, rapidly widening. Normal 

 colour of frons dark grey or blackish grey in the middle and lighter 

 gre3^ along the edges of the eyes, which latter are without any dis- 

 tinct eye margin. For a considerable space above the base of the 

 antennae the frons is occasionally quite reddish or reddish brown. 

 Lower part of the head, including oral cavity, yello.vish grey, 

 varying lighter or darker according to the individual. Ocellar 

 triangle (isosceles) distinctly raised above the surface, concolorous, 

 ocelli distinct. Antennae grey, sometimes with a slight reddish 

 brown tint, microscopically pubescent ; 2nd joint sometimes much 

 brighter, alwa3's with a short distinct bristle ; 3rd joint more or less 

 grey dusted. Arista black considerably thickened at the base, 

 where it is normally black also. The arista bears normally at least 

 6 long equidistant, bisinuate hairs ; with often an additional one 

 placed just before the first, and also a very small one near the tip. 

 There are invariably several very minute bristles at the base. 

 Palpi elongate, black or very dark blackish brown, gradually 

 thickened towards tip, with short stiff hairs ; practically as long as 

 the proboscis, which is dark brownish yellow, shining. Back 

 of head moderately dark grey, with microscopic hairs. 



ChcE-totaxy. Seven fronto-orbital bristles ; mostly curved, 

 and often pointing in different directions. Vertical triangle with 

 2 stronger longer bristles in front, crossing one another, and 2 

 smaller ones behind, which also cross each other, with 2 other 

 similar ones practically on the vertical margin of the head, with 

 I pair each side of these, of true vertical bristles. 



9 . Frons at vertex, one-fourth width of head, widening 

 only slightly, as at the level of the antenna? it is only one-third the 

 entire width. 



Fronto-orbital bristles normally arranged in two rows, an upper 

 row of four, placed closer to the margins of the eyes, the bristles 

 directed forwards or slightly to either side ; and a lower row (these 

 would be the lower fronto-orbital bristles of Osten Sacken), of either 

 three or four, which is placed nearer the middle of the frons, and in 

 which the bristles always curve inwards. The rows sometimes 

 almost form one linear row, or occasionally overlap, and sometimes 

 the upper row consists of three bristles only ; in some individuals
