(Fig. 144, PL XXXVI.) 
Thorax testaceous-brown, with dusky scales; pleurae ochra- 
ceous, densely clothed in parts with broad white scales. Abdomen 
dusky black above ; venter ochraceous. Legs black, coxae and 
venter of the femora ochraceous; ungues of the $ equal and 
simple; metanotum with four chaetae placed quadrangularly ; 
proboscis not quite as long as thorax and abdomen. 
9 . Head covered by flat broad scales, dull purplish in the 
middle, ochraceous at the sides, and white between the eyes; in 
some specimens the ochraceous scales border the eyes as well; 
clypeus ochraceous-brown; antennae almost black, with pale 
pubescence, short, only a little more than half the length of the 
proboscis, hairs long, bases of the joints with narrow pale bands; 
palpi short, black scaled; proboscis black, long, and thin, swollen 
at the tip, nearly as long again as the antennae, apex pilose; 
eyes deep purplish-black. 
Thorax testaceous-brown, covered with flat, spindle-shaped, 
dusky-black scales; over the roots of the wings and along the 
posterior part of the mesonotum are thickly spread flat dusky- 
black scales, of similar form to the flat head scales; bristles 
black ; scutellum ochraceous, with four long black bristles and 
two very small ones to the central lobe, with overlapping flat 
dusky scales, which on the lateral lobes form a small black patch ; 
the lateral lobes have large and small black bristles; metanotum 
bright brown, with purplish reflections, and with a little tuft of 
bristles on its posterior half, arising from black spots, so that 
their presence can always be detected even if the bristles have 
gone; these bristles are arranged near the apical end of the 
metanotum quadrangularly, one bristle marking each corner, 
the two lowest being rather nearer together than the two 
uppermost chaetae ; pleurae paler yellowish to ochraceous, densely 
clothed in parts with short, broad, white scales. 
Abdomen covered with dusky-black scales, with the posterior 
borders of the segments with very minute border-bristles; venter 
ochraceous, clothed with pale, almost creamy-yellow scales. 
Legs long, black; coxae very pale, and also the ventral
