164 THE ENTOMOLOGIST. 



creamy yellow in colour, running down the centre and along the orbital 

 margins, and behind over the nape, scattered among the flat black 

 scales, are a few white narrow-curved ones ; laterally there is a patch 

 of white flat scales succeeded by black scales, which are followed again 

 by white scales ; on the vertex, projecting forwards between the eyes, 

 is a tuft of pale golden bristles ; there are other bristles along the 

 orbital margins which are black at the base and pale at the tip. 

 Antennae witli the basal joint dusky black, with small black spindle- 

 shaped scales on its inner face (in some specimens this joint is ferru- 

 ginous), remaining joints black; second joint black-scaled ; verticillate 

 hairs black ; all the joints after second clothed with short silky white 

 hairs. Clypeus black, frosted. Palpi yellowish -brown, four-jointed; 

 first joint constricted in the middle ; fourth joint very small, clothed 

 with black spatulate scales except towards the tip, which is white- 

 scaled. The amount of this white scaling varies. In one specimen it 

 includes little more than the last joint, in another one it includes half 

 the penultimate joint. Proboscis yellowish-brown, black-scaled dorsally 

 and laterally ; beneath it is white-scaled ; about half way white scales 

 appear laterally, and may even go right round, forming a complete 

 band. Prothoracic lobes simple, prominent, white-scaled. Mesonotum 

 dark brown, clothed with narrow-curved scales, black under a hand 

 lens, but under a two-thirds power the tips appear pale golden ; there 

 is a central line of pale golden scales which forks in front of the 

 scutellum, enclosing an unsealed area ; on either side there is another 

 line which runs back about one-third the total distance ; placed a little 

 further out is another line running forwards from the scutellum and 

 ending just a little to one side oi' the anterior lateral line ; there is 

 another golden line over the roots of the wings, and on the anterior 

 margin, just above the prothoracic lobes, are scattered white scales ; 

 there are numerous black bristles arranged in lines. The scutellum is 

 fawny brown ; on the central lobe there is a patch of black almost 

 spindle-shaped scales arranged in a rosette, with a central line of 

 creamy white scales which become narrow-curved scales at the apex of 

 the scutellum ; the lateral lobes have a few black narrow-curved scales. 

 The scutellum is not heavily scaled, and the scales are quite unlike 

 those of an ordinary Steijomijia ; there are four to six bristles on 

 the central lobe, two of which are pale golden, four black. Pleurae 

 dark brown, with patches of broad white scales. Wings clad with 

 black scales ; median scales rather long and narrow spatulate-shaped ; 

 lateral scales lanceolate ; some white scales on the costa at its base. 

 Fork-cells of moderate length ; first submarginal longer and narrower 

 than second posterior, its base nearer the base of the wing, the cell 

 longer than its stem. Supernumerary and mid cross-veins meeting at 

 an angle ; posterior cross-vein twice its own length from mid cross- 

 vein. Legs with the coxae creamy yellow ; femora of fore and mid 

 legs black-scaled dorsally and laterally, white-scaled beneath ; a ring 

 of golden brown spines around the apex ; tibife the same as femora 

 minus the spines, except that the extreme apex is clothed with a few 

 creamy yellow scales ; metatarsus and first tarsal joint basally banded 

 with creamy yellow, the remainder black-scaled ; ungues equal and 

 uniserrate ; hind femora scaled as the others, except for a patch of 

 white scales about the middle of the anterior and posterior surfaces ;
