similar pubescence becomes greyish on the jowls and on the moderately 

 inflated lower part of the back of the head ; frons rather small, and bearing- 

 similar black pubescence ; upper part of the back of the head very shallow 

 but hardly hollowed out, and bearing only a very short black ciliation ; 

 vertex very much elevated, and bearing black pubescence similar to that on 

 the frons and face. Proboscis short, but the sucker-flaps large and dull 

 orange ; palpi imperceptible. Eyes touching for _ a long _ distance, rather 

 densely clothed with brownish-black pubescence which is slightly longest on 

 the front part of the large facets ; facets on rather more than the upper half 

 of the eyes distinctly larger than those on the lower part, and the line of 

 distinction fairly well defined. Antennje longer than the head, dull black 

 with occasionally the tip of the second joint yellowish orange, first_ joint 

 hardly longer than the second, and both bearing short black bristles ; 

 third joint almost strap-shaped, slightly attenuated, almost three times as 

 long as the two basal joints together, annulated, and minutely pubescent at 

 the tip. 



Thorax and scutellum shining black, coarsely punctate, and clothed with 

 dense blackish pubescence ; outer points of the humeri orange ; pleurae clothed 

 with considerable greyish-yellow pubescence, especially on the lower part, but 

 the middle of the mesopleurae bare and polished. Scutellum usually with six 

 black thick spines, but there may be four, five, seven, or eight such spines of 

 which one X)r two may be imperfect, and these spines bear blackish 

 pubescence. 



Abdomen conspicuously brownish orange ; basal segment black except on 

 the hindmarginal two-fifths, and usually the hindmargin of the sixth and the 

 upper part of the small seventh segment are blackish, but as a rule there is 

 no trace of any narrow black cross-bands near the hindmargins of the segments ; 

 pubescence black and not scarce, fairly long down the sides. Belly all 

 orange, and bearing minute pale pubescence. Genitalia orange with the upper 

 pair of lamellae and usually the extreme base blackish. 



Legs dull orange or sometimes rather bright orange, with about the apical 

 two-thirds of all the tibiae (except the extreme tip) and the tarsi blackish 

 brown ; coxae blackish, but rather orange at the tip and on the trochanters, 

 and bearing pale pubescence ; basal joint of the hind tarsi obviously dilated, 

 as long as or slightly longer than the other four joints together. Pubescence 

 on the femoi-a pale and inconspicuous ; hind tibiae with a moderately long 

 fine dark ciliation inside (= behind) on the aj^ical two-thirds. 



Wings blackish brown to brown, but more yellowish brown about the 

 base ; stigma moderately conspicuous. Alar squamae moderate in size, 

 obscurely blackisla or brownish, with moderate pale brown fringes ; thoracal 

 pair almost absent. Halteres dull orange. 



?. Eather similar to the male, but with much lighter wings. Frons broad, 

 more than one-third the width of the head (in one specimen less), shining 

 black and sparingly punctate, and with rather sparse minute greyish 

 pubescence ; face slightly wider than the frons_, and bearing sparse pale 

 pubescence ; jowls and back of the head with similar pubescence, and the 

 back of the head slightly puffed out with all the upper part on the inflated part 

 against the eyes greyish and bearing more obvious grey pubescence. Eyes 

 with much shorter and sparser pubescence. 



Thorax, pleurae, and scutellum with less coarse yellowish -grey pubescence. 



Abdomen not blackened at the base and usually with only the apical prongs 

 blackened, but sometimes the fifth and sixth segments are slightly blackened 

 on the disc, or a dark dorsal line may occur on the basal segments, or the 

 belly may be slightly blackened on about the middle of its disc. Pubescence 

 all pale yellow, inconspicuous but not scarce. 



Legs with the ciliation inside the hind tibiae present but pale ; basal 

 joint of the hind tarsi hardly dilated, perceptibly longer than the other four 

 joints together. 



Wings only pale brownish, and consequently the dark brown stigma 

 very conspicuous ; wings more yellowish about the base. Squamae more 

 yellowish, with pale yellow fringes. 



Length about 6 mm.
