irreoular reddish patclie?, but Avitli no sign of dark or black- 

 ened spots except the usual iiairy neck-spot, an excessively 

 faint large spot behind the vibrissa, and the brownish-red 

 ocellar spot; the antenna lias a darkish flageHum with very 

 long hairs, and the tliird joint has its absolute ridge red. 

 Side-view : — Jowls, palpi, tongue (also the face) all yellow ; 

 hind head and hiwer side bristly as usual ; vibrissa very 

 strong ; eyes rather rectangularly oval, with long axis 

 vertical ; jowls about as deep as breadth of third joint of 

 antenna. 



Thorax : dorsum dull dark coffee-brown, except the much 

 lighter callus and front of dorsum ; the liglit part quickly 

 merges into the dark just as the true dorsum begins ; two 

 dark lines start near the neck, and continue right over the 

 dorsum, but are necessarily very faint on the dark part ; 

 between them, and also along the d. c. lines, are two faint 

 narrow lines showing up more ochreous than the rest. Scu- 

 tellum flat, slightly shining, quite bare, with a few tiny ridge- 

 hairs between end- and side-bristles. All the macroclisetes 

 are Jong, but slender for the size of the insect; side above the 

 notopleural suture from the callus rather brown and shining, 

 below the pleura is as dark as dorsum, though a little more 

 shining ; mesopleura absolutely bare ; nietanotum dull, more 

 grey ; all bristles normal. 



Wings darkened, the costal bristles stout and about fifteen 

 in number from end of vein 1, ceasing about level of hind 

 crofcs-vein. The general colour of the wing is biown ; from 

 the end of 1 to the tip a daiker brown covers the wing up to 

 about the middle of the cubital cell ; the distal part of this 

 extra darkening extends across the wing ; the basal parts of 

 veins 3 and 4 are included in another darkened area, the 

 small cross-vein and neighbouring parts of 3 and 4 in 

 another, and the hind cross-vein and near parts of 3 in yet 

 another ; there are clear " windows " between the veins at 

 the base, and the usual "window" just distal of the anal 

 cell shows very brightly ; the absolute costa between ends of 

 2 and 4 is pale ochreous, but otherwise all the veins are 

 brown. Hatteres clear white. 



Legs : femora all elegantly spindled, mid less so than others, 

 with long profuse blackish hairs at i-ides and below. Colour : 

 all coxse and trochanters orange, more or less darkened, all 

 femora shining black, all tibise orange, front with black tip, 

 hind suffused; all with long hairs below, which are ex- 

 cessively long on distal half of middle tibia; all tarsi orange, 

 the last joints daik and first joint of middle one with very- 

 long hairs. Bristles : — front femur a superior row of about 7,
