shorter, and on the lower part of the side-cheeks and below the eyes the 

 tawny hairs extend up to the eyes even though a few straggling black hairs 

 also reach to these parts ; behind the mouth the dense long pubescence is 

 dark reddish tawny mixed with black, but on the small dull orange jowls it 

 is nearly all dark reddish tawny and merges into the tawny pubescence on 

 the lower part of the pleurae ; back of the head not much puffed out, clothed 

 with very dense coarse browmish tawny pubescence in which no black hairs 

 are intermixed and which merges into the similar dense pubescence of the 

 thorax ; vertex dull Ijlack, elevated, and bearing a tuft of long exclusively 

 black hairs. Proboscis rather shining black, as long as from the front of the 

 head to the tip of the scutellum. Eyes touching for al)Out as long a space 

 as the length of the vertex, hardly widening from toj) to bottom. Antennae 

 dull l)lack ; basal joint linear and about five times as long as wide, covered 

 with brownish orange or greyish dust and bearing all over (except on the 

 basal third) numerous but not dense long straight black hairs which are 

 directed forwards and outwards ; second joint about one-third the length of 

 the basal joint, long cup-shaped, also rather obscured by brownish orange 

 dust but ferruginous at the tip, and with numerous short black hairs on the 

 upper and outer sides which i)oint almost straight forwards ; third joint long 

 strap-sha])ed, quite twice as long as the basal joint, gradually diminishing 

 towards the tip ; style short, two-jointed, the basal joint being short transverse 

 but the end joint conical and ending in a point. 



Thorax with a dull black ground colour which is obscured by very dense 

 tawny pubescence ; this pubescence besides being very dense is perfectly 

 equal just as if it had been shorn, but when seen from above the ground 

 colour shows somewhat through on the disc and causes a blackish brown 

 appearance, while the sides are shimmering paler tawny and indicate a 

 dei>ressed wliitish yellow patch just above each wing-base and similar but 

 longer haired depressed patches on the postalar calli ; seen from in front the 

 pubescence is brownish yellow but paler posteriorly and the same two patches 

 appear less distinctly whitish, while right on the middle of the front part a 

 reddish brown short V-shaped marking becomes obvious ; seen from behind 

 the pubescence is almost all unicolorous pale brownish yellow without any 

 whitish patches, though when tilted the short forked brown line right in front 

 is visilde ; seen sideways the pubescence is all yellowish but with possibly a 

 slight brownish tinge on the front part, and thence backwards with a whitish 

 shimmer down the disc, but usually without any visible whitish patches or 

 brown front line ; a microscopical examination fails to show any black hairs 

 or any approximation to bristly hairs anywhere, though the patches of 

 depressed whitish hairs seem to be of a different texture to the rest of the 

 pubescence ; pleurae with dense deep black hairs extending widely from the 

 front part to the wing-base, but after that and on quite the lower ])art of the 

 mesopleurse with dai'k reddish brown ])ubescence, that on the back part 

 being longer rather less dense and somewhat directed backwards ; just behind 

 the wing-base a bright reddish orange tuft pointing backwards is conspicuous 

 ( = fringe of alar squamae) and a similar tuft occurs on the metapleurse, but 

 both these tufts are quite distinct from the long yellow fringe on the alula?. 

 Scutellum with its pubescence merged into that of the thorax and ■with no 

 long marginal hairs. 



Abdomen dull black, but obscured by very dense long i^ubescence which 

 is brownish yellow on all the basal two-thirds but black on the rest ; 

 pubescence on the belly all black excejjt at the sides near the base, and this 

 black pubescence extending upwards on the sides of the abdomen at the 

 junction of the second and third segments and up all the sides of the fourth 

 segment ; the anal black pubescence apparently coarser and more tangled 

 than the brownish yellow pubescence, and including some isolated rather 

 longer thin hairs, while a few isolated long black hairs may occur amongst the 

 tawny_ hairs on the hindmargin of the fourth or even third segment, and 

 sometimes a few isolated inconspicuous long thin tawny hairs occur in the 

 black pubescence ; when seen from behind the tawny pubescence has a paler 

 sheen about the sides, and extends furthest down the sides of the first 

 and second segments. 



Legs dull orange, but the coxae, trochanters, and most of the femora
