238 THE KNTOMOLOaiST, 



set in a bare space which appears as a black margin ; flanking the 

 median line of white scales on either side is a line of tawny scales, 

 and outside this line is a patch of white scales anteriorly and a bare 

 space having the appearance of a black spot owing to the dark colour 

 of the metanotum ; the posterior part of the thorax is chiefly occupied 

 with a diamond-shaped patch of tawny scales edged with a few black 

 scales and a bare space ; outside this are white and tawny scales 

 arranged somewhat irregularly. The arrangement of the scales 

 varies considerably. Another specimen I have seen shows a central 

 line of white, black and tawny scales from the front backwards, and 

 flanking this is a bare line, and then a large patch of purple-black 

 scales. In a dry specimen the scales have a very ragged appearance, 

 and, being twisted this way and that, have not the same appearance 

 of a definite arrangement as in a fresh specimen. Scutellum dingy 

 yellow, clouded with black ; all three lobes clad with rather long 

 white narrow-curved scales, Scutellar bristles brown. Wings covered 

 with black and white, broad spatulate in some specimens, almost 

 spindle-shaped scales in others. Costa black scaled with white spots ; 

 the first spot close to the base and involving the base of all the long 

 veins ; the second involves the costal, sub-costal and first long vein ; 

 the third involves the veins as far as the fourth long vein. The fourth 

 passes on to the base of the first fork-cell, and the fifth spot is very 

 narrow and involves the lower branch of first fork-cell; there is a spot 

 on the wing field at the base of the second long vein, and another on 

 the upper branch of the fifth vein near its base, and one at its apex and 

 anotlier spot at the base of the second fork-cell. Supernumerary and 

 mid cross-veins form an obtuse angle towards the base. Posterior 

 cross-vein distant about four times its length from the mid cross-veins. 

 Pleuras dark brown, thickly covered with broad flat white scales. 

 Legs with the fore coxfe pale, with creamy scales in the front legs, and 

 hind and mid dark brown, with a few white scales ; femorae clad with 

 purple scales freely mottled with golden ; on the fore legs is a ring of 

 golden scales a little before the apex which does not include the upper 

 face ; on the mid and hind legs the scales at the apices of the femora 

 are elongated, and give an ill-marked feathered appearance to the 

 legs ; the tibiae are mottled purple and golden, and at the apices of all 

 the tibiffi is a band of creamy yellow scales ; the base of the metatarsus 

 and first two tarsal joints on the fore and mid legs are banded with 

 creamy scales ; in the hind legs the base of the metatarsus and first 

 tarsal joint are banded, and the last three tarsal joints are creamy 

 white. Ungues equal and simple on all the legs. Abdomen covered 

 with purple-brown scales ; each segment bears on the dorsum two 

 spots of white scales placed on either side of the middle line and 

 rather nearer the apex than the base ; laterally there is a basal patch 

 of white, apically a band of white scales. Some specimens bear 

 numerous golden hairs on the apex of the segments dorsally; ventrally 

 each segment is basally banded, and some of the segments have a 

 median white spot. 



" 3" . Head brown ; the narrow- curved scales form a dense tuft be- 

 tween the eyes and a more definite margin to them than in the female. 

 There are more white upright forked scales, the brown comprising
