Megaculex pincerna, sp. n. 



? . — Head: the middle of the occiput is covered with broad 

 white upright forked scales, with white narrow curved scales 

 between them. On either side are lateral areas of long cream- 

 coloured flat scales, enclosing small areas of purplish-brown 

 flat scales. There is a row of small black upright forked 

 scales near the nape. Five pale bristles surround each orbit, 

 and similar bristles project between the eyes. Palpi brown, 

 with cream-coloured scales at apex. Proboscis brown, paler 

 and somewhat expanded towards tip. Clyptus dark brown,

 brown elongated scales; plume-hairs brown, paler at tips. 

 Eyes blue-black. Thorax dark brown, covered with pale 

 golden scales, showing two longitudinal bare lines, which 

 divide up the middle of the mesonotum into three golden 

 bands ; on either side of the external bands is a flavk bmrnm 

 scaled laical area, and further back in fiont of each wing- 

 insertion is a small iaic;<u wtnte spot. In the posterior half 

 of the mesonotum the middle is occupied by a dark-scaled 

 wineglass-like figure, the stem standing upon the scutellum ; 

 on each side is a dark elongate area, extending forward 

 beyond the wings. There are pale brown divergent bristles 

 on the anterior edge of thorax, and bunches of darker con- 

 vergent bristles arising behind the wing-insertion and pro- 

 jecting backward. Scutellum covered with nearly white
