122 Rev. H. Clark on the Chrysomelida of South Africa, 



transverse et subcirculariter depresso, leviter punctate ; thorace 

 sat parvo, lateribus baud parallelis, apicem versus distincte an- 

 gustatis et rotundatis, angulis anticis baud acutis, ad latera fortiter 

 et confertim, ad discum leviter et rarius punctato, nigro-seneo, 

 lateribus late rufis ; scutello subtriangulari, Isevi, rufo-fusco; 

 elytris seriatim punctatis, basi, marginibus plagisque lougitudina- 

 libus 3 rufis ; corpore subtus, pedibus antennisque fusco-nigris.

The longitudinal markings in' this species may perchance be 

 subject to variation : in the single example before me they are 

 ranged — (1) between the 2ud and 3rd striae, from the basal 

 colouring to the middle; (2) between the 3rd and 4th striae, as 

 a small medial spot of rufous; (3) between the 4th and 5th 

 striae from in front of the middle to the apex ; (4) between the 

 6th and 7th striae, and here subdivided into three markings, — 

 a, from the basal markings to before the middle ; b, 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 Eumolpidae, 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. lineolata, 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
