shorter) all round the upper eye-angles and then form a barely-more-than- 

 double-rowed rather longer ciliation down the orbits, but otherwise the frons 

 IS bare • collar with a dense rather rigid black fringe but without bristles. 

 Proboscis long, thin, horizontal, and with the usual pubescence ; palpi very 

 short and linear, bearing rather long porrect black Hairs. Eyes with the 

 facets on the comparatively small flattened front part very much larger than, 

 and rather abruptly contrasted with, the small facets. Antennas dull black ; 

 basal joint long and cylindrical, about six times longer than broad and three 

 times longer than the second joint, bearing long but not dense black bristly 

 hairs and about two extra long strong black hairs on the underside near the 

 tip • second joint rather cup-shaped, bearing shorter black bristly hairs ; 

 third joint bare (or with a tiny dorsal bristle at about a quarter from the 

 base) "usually longer than the two basal joints together and beginning hardly 

 so broad as the tip of the second joint but gradually increasing to almost 

 double that width and then again gradually decreasing, or sometimes rather 

 more club-shaped and then only as long as the two basal joints together 



Thorax blue-black, moderately shining and with an elongate sloping 

 shimmering whitish spot (hardly visible in some lights) on the upper half of 

 each humeral knob ; pubescence composed of rather sparse decumbent 

 brownish yellow or grey hairs and some longer sparser more erect (though 

 still sloping) black hairs, but the humeri bear only rather more dense black 

 hairs ; amongst this pubescence are indications of four or five prsesutural 

 bristles, about five (5-6) supra-alar, about three postalar, and about four 

 very weak postsutural dorso-central. Pleurae in most lights shimmering 

 greyish white almost all over ; prothorax with only a few black hairs near 

 the lower margin, but the space below it rather conspicuously white-haired ; 

 mesopleuree with rather sparse black pubescence all over and at least one 

 rather strong black bristle near the middle of the hindmargin ; sternopleura) 

 with faint traces of pale pubescence ; metapleuree with numerous extra long 

 hairs which represent (but hardly form) the fan of mixed black and orange 

 curled hairs, of which none are at all bristle-like; hypopleuraj with only 

 faint traces of pale pubescence. Scutellum bearing short brownish yellow 

 pubescence on its disc similar to that on the thorax but rather less recumbent, 

 and about eight long upturned orange or blackish marginal hairs (hardly 

 bristles); raetanotum quite bare, hidden by the overhanging scutellum except

Abdomen shining blue black, with rather short but conspicuous tawny 

 recumbent pubescence which in some lights is apparently (though not really) 

 absent from the large basal corners of the second to fourth segments (the basal 

 segment being very short and inconspicuous with a little pale pubescence 

 near its sides), and this tawny pubescence grows longer and denser at the 

 sides of the basal segments and at the hind corners of each segment and 

 appears to form broad lunules which curve up and unite broadly on the 

 middle of the disc ; a few tiny black almost bristly hairs occur on the middle 

 of the disc of the seventh segment and about three orange bristly hairs can 

 be found amongst the tawny pubescence near each front corner of the second 

 segment, and about three more on the third segment in a row near the middle 

 of each side, and two similar bristles on each of the next two segments, whde 

 the sixth and seventh segments bear an indistinct similar bristle on each side ; 

 eighth segment very short and only just visible dorsally. Belly glistening 

 black, very sparsely and finely punctate, with each punctuation producing a 

 rather long thin grey hair ; hindmargins of segments rather widely but 

 obscurely orange. Genitalia shining black, rather more than half the width 

 of and about as long as the last abdominal segment, but when viewed side- 

 ways apparently much larger througli being composed of one large solid 

 swollen underpart which extends back beneath the last abdominal segment, 

 and this swollen underpart slopes upwards so as to nearly reach the tip of the 

 upper lamellae and bears numerous short stiff" black hairs and near the tip a 

 few longer black bristly hairs, while after them on the small elongate apical 

 pieces are a few shorter pale hairs ; upper lamellae (when viewed from above) 

 separated at the base but soon touching and bearing similar short stiff black 

 hairs and on the upper side near the tip denser longer stouter bristly hairs. 

 Legs black ; femora stout and shining ; hind femora considerably club-
