Post-vertical bristles absent. 



Para-frontals tawny, with fuscous reflections ; triangular, being narrowed 

 towards the vertex ; bare but for frontal bristles, which are convergent in a 

 single row, extending to about the base of antennae (fig. 2. h, b) ; lower 

 fronto-orbital bristles weak, the upper, 3 in number, divergent, in line with 

 middle fronto-orhitals, themselves weak and convergent. 



Para-facials bare, ochreous-yellow with tawny reflections, slightly swollen, 

 rectangular in profile but narrowing slightly towards the orbit (fig. 2, c, c). 



Cheeks of same colour as para-facials, bare but for a secondary divergent 

 row of weak peristomal bristles, wide towards occiput, narrowed towards 

 the facio-peristomal angle, height less than that of eye. 



Posterior orbits bare, tawny, widened below ; lower margin of the head 

 straight. 



Occiput tawny, flat above, swollen beneath, causing posterior margin of 

 cheek to bulge slightly, and bearing stiff golden hairs above, which are 

 longer and slender below ; occipital area restricted to occiput ; post-orbital 

 bristles proclinate. 



lyiorax. 



Sterno-pleiiral bristles strong, 3 in number, a pair being approximated a 

 little anterior to the line of meso-pleural suture (fig. 3, a), and a single larger 

 and longer bristle posterior to the line of this suture (a') ; surface of sterno- 

 pleurae with scattered bristles. 



Ptero-pleural bristles long, 4 in number, a pair of strong (c, c') and a pair 

 of weak bristles {d) being arranged alternately near wing-articulation (e) ; 

 around the insertion of these bristles are 

 scattered black hairs, otherwise this seg- 

 ment is bare. 



Meso-pleural bristles long, strong, 7 

 in number, 6 placed along mesopleural 

 suture {g), the 7th, which is shorter; in- 

 serted in the vicinity of the upper ante- 

 rior angle of pleura {(/). 



Pro-pleural bristles strong, 3 in num- 

 ber {k). 



Nofo-pleural bristles strong, reclinate, 

 2 in number (fig. 4, a).

 long, extending beyond the scutellum, not 

 exactly in line with the others, but inserted slightly towards the post-alars. 



Dorso-central bristles long, 6 n number, 3 in each row (c). 



Acrostichals {d) strong, 8 in number, 4 in each row, shorter than the 

 post-suturals ; the posterior pairs are nearer to the scutellar than to the 

 dorsal suture, the posterior ones being more erect. 



Humeral bristles strong, reclinate, 5 in number, the most anterior more 

 erect than the others ; a pair upon lateral margin, one upon anterior margin, 

 another in the centre of the humerus, and a delicate one between but in 

 from the anterior and central chaetae (e). 



Post-humeral bristles 3 in number, the anterior and posterior ones weak, 

 not being in line with the strong intermediate bristle (/). 



Pre-sutural bristles 2 in number, the one nearer to the dorsal suture 

 weak {p).
