112 THE ENTOMOLOGIST. 



Clypeus rounded and black. Prothoracic lobes prominent, upper 

 surface covered with broad white scales. Mesonotum dark brown ; in 

 front of the wing bases the mesonotum is entirely clad with long silky 

 white scales, except for a small notch of bronzy scales on either side ; 

 the white scaling has much the appearance of an inverted Y with 

 a very thick stem, and there are white scales on the lateral margin ; 

 at the root of the scutellum is a bare patch. On either side there are 

 a few white narrow scales. The rest of the mesonotum is clad with 

 bronzy narrow-curved scales. There are a row of bristles along the 

 anterior margin of the mesonotum and over the roots of the wings. 

 Scutellum yellowish-brown ; central lobe clad with white and black 

 narrow-curved scales ; lateral lobes with white-curved scales. Scutellum 

 bristles oehraceous. Metanotum dark brown. Wings of Cnlcx type, 

 clad with dark brown scales ; the median scales rather long and 

 narrow, lateral scales long and narrow with square ends. Fork-cells 

 moderately long ; first submarginal longer but scarcely narrower than 

 second posterior, its base nearer base of wing ; the stem about two- 

 thirds the length of the cell. Supernumerary and mid cross-veins 

 meet at an angle. Posterior cross-vein about three times its own 

 length from mid cross-vein ; fringe scales black. Pleuras with seven 

 patches of silvery white broad scales, arranged in two rows of three 

 and one patch above the middle coxa. Metanotum dark umber brown. 

 Legs with the coxfe creamy, fore and mid legs pale yellowish covered 

 with black spatulate scales, except the under surface of the femora 

 which shows a line of white scales, the under side of the base of the 

 tibia, the apex of the tibia, which is ringed with creamy yellow scales 

 in the fore leg, and the base of the metatarsus, and the first tarsal 

 joint which in both legs show a white band ; hind femora covered with 

 black scales ; a ring of white scales, about one-third of the total length, 

 extends round the whole circumference save for a narrow line on the 

 dorsum ; on the under surface of the apex some creamy yellow scale 

 and a minute ring of the same placed just before the apex. Knee 

 spot and under surface of tibia white scaled ; a broad white band 

 at the base of the metatarsus and first three tarsal joints. Fore 

 and mid ungues equal and uniserrate. There are some pale golden 

 bristles on all the tibiae. Abdomen covered with black scales with 

 basal white bands which expand laterally into broad spots, especially 

 large on the seventh and eighth segments. Segments beneath brown 

 scaled, basally white banded. 



" ^. Head black, frosted, clad almost entirely with broad white 

 flat scales parted in the centre over the occiput, leaving a bare line of 

 the black head showing broadest in front ; laterally there is an oblong 

 patch of black scales which may almost disappear if the head shrinks 

 much in drying ; more laterally still a round patch of black scales. 

 Between the edge of the first patch and the orbital margin is a row of 

 white narrow-curved scales ; there are other narrow-curved scales 

 on either side of the middle line just above the occipital foramen 

 and a few on the vertex between the eyes. There are a moderate 

 number of upright forked scales behind and a few inserted among the 

 black scales of the most median of the two black patches ; they are 

 dark brown in colour ; there are five brown bristles on either side 

 projecting forwards ; in some specimens the median bristles are pale
