122 Rev. H. Clark on the Chrysomelide of South Africa. 
transverse et subcirculariter depresso, leviter punctato ; thorace 
sat parvo, lateribus haud parallelis, apicem versus distincte an- 
gustatis et rotundatis, angulis anticis haud acutis, ad latera fortiter 
et confertim, ad discum leviter et rarius punctato, nigro-zeneo, 
lateribus late rufis; scutello subtriangulari, leevi, rufo-fusco ; 
elytris seriatim punctatis, basi, marginibus plagisque longitudina- 
libus 3 rufis ; corpore subtus, pedibus antennisque fusco-nigris. 
Long. corp. lim. 23; lat. 12 lin. 
The longitudinal markings in this species may perchance be 
subject to variation: in the single example before me they are 
ranged—(1) between the 2nd and 3rd striz, from the basal 
colouring to the middle; (2) between the 3rd and 4th strie, as 
a small medial spot of rufous; (8) between the 4th and 5th 
striz from in front of the middle to the apex; (4) between the 
6th and 7th striz, and here subdivided into three markings,— 
a, from the basal markings to before the middle; 8, a post- 
medial, shorter, and more obscure marking; c, a subcircular 
spot near the apex. It is quite possible that, in some examples, 
markings 1, 2, and 3 may be confluent, and also that those 
under 4 may be continuous. 
I know of one specimen only of the species, which I received 
from the collection of M. Chevrolat. In naming it, I desire to 
testify my sense of obligation to my friend the Rev. T. A. Mar- 
shall, who is undertaking the Herculean task of systematizing 
the Eumolpide, and who already gives ample encouragement for 
us to believe that success will attend his labours in a field con- 
fessedly most difficult, as well as at present unmeasured in 
extent.

At first sight this species nearly resembles P. ineolata, the 
longitudinal markings being generally similar; over and above 
the contrast, however, which, on examination, will be apparent 
in the patterns, the species before us may readily be separated _
