 with a slight blackish grey tinge except at the tip, and clothed with 

 long (but shorter than that on the jowls) thin pale yellowish grey 

 pubescence ; second joint oblong ovate, bladdery, about twice as long 

 as its thickest part which is in a little before its middle, and ending in 

 a rather sudden blunt conical or sometimes evenly rounded tip, and 

 usually with a slight compression beneath just before the tip, widely 

 clothed on its outer part with long (but shorter than that on the basal 

 joint) soft thin whitish pubescence which is intermixed with 

 shorter but stouter blackish hairs on about the apical two-thirds of its 

 lower part, especially at the tip very conspicuous. Antennae dull 

 orange red or rather darker ; basal joint stouter and shorter than that 

 in the female, covered with dark grey or greyish tomentum, much

 much paler or sometimes quite yellow, with a narrow dorsal apical 

 process which is usually longer than that in the female, and with more 

 conspicuous black circlet about the apex ; third more slender, with 

 the basal annulation about twice as long as its broadest part, and with 

 the style-like portion about four-fifths as long as the broad basal an-

 Eyes quite bare, very much larger than that in the female broader 

 than the thorax and about as broad as the broadest part of the abdo- 

 men, and about four-fifths as long as the thorax (not including the 

 scutellum) ; when seen from the above triangular with the evenly 

 rounded outer margin, the frontal margin as long as the hind margin 

 which is very slightly curved inwards about the middle ; in profile 

 .somewhat irregular trapezoid, with nearly straight frontal margin and 

 with very slightly outwardly curved facial-, buccal-, and hind-margins, 

 die hind angle most blunt and rounded, the lower angle about ioo° 

 and broadly rounded, the frontal angle about 90° and rounded, and 

 the upper angle about 70° and more or less rounded ; when seen
