PlEZIA MaSHUNA. 



Head and prothorax as in P. axillaris, the latter part not so broad, 

 white lateral bands alike ; elytra gradually ampliated from the base 

 to past the middle, but very little narrowed from the median towards 

 the posterior part, plane, six-costate, with the usual double series of 

 white hairs, a sutural white band covering the first interval on each 

 side from the base to beyond the middle, and an apical sutural patch 

 extending on each side as far as the second costa. Length 20 mm. ; 

 width 8 mm. 



Hab. Zambezia (Salisbury). 



PiEziA Marshalli. 



Head and prothorax as in P. Mashima, and with the white bands 

 alike ; elytra regularly elongato-ovate, that is to say, gradually 

 ampliated from the base to the median part, and from there 

 gradually narrowed towards the apex, six-costate, with a sutural 

 white band placed on each side on the first interval, reaching from 

 the base to about the middle, and with two transverse maculae 

 merging into one another in a line with the apical part of the sutural 

 band, and placed on the third, fourth, and fifth intervals, and an 

 apical sutural white patch extending as far as the second costa on 

 each side. Length 20 mm. ; width 7^-8 mm. 



Hab. Zambezia (Salisbury). 



Piezia dissidens. 



Head and prothorax as in P. Marshalli, the prothorax somewhat 

 broader and intermediate in width with that of the last-named 

 species and P. axillaris, cephalic and thoracic white bands alike ; 

 elytra gradually ampliated from the base to the middle, but hardly 

 narrowed from there towards the posterior part, which seems to be 

 more abruptly truncate on account of it being broader than in the 

 other species ; the sutural band is the same as in Marshalli, but the 

 median dorsal white spots have merged into a sinuose narrow trans- 

 verse band reaching from the second to the fourth costa on each side, 

 apical sutural patch of the shape and size of that of P. Marshalli. 

 Length 20-21 mm. ; width 7-8^ mm. 



Had I not seen a good series of both sexes of P. Marshalli and P. 

 dissidens, I would have felt inclined to consider the latter as the 

 female of the first-named species ; the distinctive character consists 

 in the shape of the elytra, which are not regularly elongato-ovate as 

 in Marshalli, but hardly narrowed past the median part. 



Hab. Zambezia (Salisbury). 



Piezia virgulifera. 

 Head and prothorax of the same shape and with the same white 

 bands as in P. Marshalli ; elytra of the same shape, but with a
