dorsum with lateral borders, an entire narrow median longi- 

 tudinal stripe (slightly broader posteriorly), a pair of ad- 

 median stripes (interrupted beyond transverse suture), and a 

 short and broader stripe on each side, extending from upper 

 angle of praesutural depression to hind border and continued 

 round scutellum, light grey or pearl-grey ; usual crescentic 

 marks on hind border (continuations of admedian stripes) 

 divided or partially so; dorsum, including scutellum, clothed 

 with minute, appressed, deciduous, pale yellow hairs ; pleurae 

 and pectus light grey. Abdomen : dorsum of each segment 

 with a pair of smoke-grey admedian spots, those on second 

 and following segments not in contact with hind margin ; 

 venter grey, clothed with minute, appressed, pale yellowish 

 hairs, hind margin of third and following segments, and of 

 second segment except at sides, cream-coloured, a gradually 

 expanding clove-brown median stripe, interrupted on hind 

 margins of segments, starting on third segment aud extending 

 to distal extremity. Wings very similar in coloration and 

 markings to those of H. insidiatrix, Austen, but pale 

 markings not quite so light in colour and slightly coarser, 

 and no trace of light fleck near distal margin of second sub- 

 marginal cell, beyond apical sinuous mark ; stigma seal- 

 brown, conspicuous, of moderate length, with a distinct light 

 mark running up to costa at its proximal extremity j no 

 conspicuous dark blotch below stigma ; discal cell with two 

 approximate transverse light marks (distal one divided) in its 

 middle portion, a large light spot in its distal third, and a 

 minute and indistinct light fleck near its proximal extre- 

 mity ; disconnected oblique light marks across posterior cells 

 divided or partly divided ; a series of not very conspicuous 

 light blotches along hind margin, in distal angles of posterior 

 cells except fourth ; some minute light flecks near distal 

 extremity of anal cell ; light markings in basal, anal, and 

 axillary cells of normal type, zigzag mark and light loop in 

 axillary cell conspicuous but not connected, light blotch on 

 sixth vein beyond zigzag mark of fairly large size and distinct ; 

 alula with pale border. Hal teres cream-buff, knob pale seal- 

 brown above and below. Legs : femora pale greyish choco- 

 late ; tibiae and middle and hind tarsi dark brown, extreme 

 bases of tibiae and pale bands on latter, as also basal half or 

 two-thirds of first joint of middle and hind tarsi, buff; front

Hamatopota puniens is very closely allied to H. abyssinica, 

 Surcouf, of which it may ultimately prove to be a local race ;
