 antice sat rotundato, sparsim subtiliter, ad latera fortius punctato,

One of the more common species, and apparently subject to 

 but slight variation : the markings on the elytra are almost 

 constant, being very seldom indeed confluent ; the thorax is 

 subject to greater modification of colour. 



I adopt the name which I find appended to this species, 

 although I cannot discover the reference to any description by 

 Thunberg in 'Act. Reg. Soc. Ups/ viii., where he publiahed 

 several, but very insufficient, descriptions of Cape insects.

A common species at the Cape, and one that, being subject 

 to some variation of pattern, has been provisionally recorded by 

 collectors under different names, as P. lineolata, P, pulchra, &c. 

 It certainly is entirely distinct in all its patterns from P. notata, 

 Fab., with which it has been confounded, as being a permanent 

 variety. The thorax varies as to pattern, in different examples, 

 from rufo-flavous, with four isolated subcircular markings, to 

 black, the sides and a medial line ftnly being flavous; and the 

 elytra in some specimens before me have the two series of 

 markings continued into each other : in all examples, however, 

 these longitudinal markings terminate ahttle behind the middle, 

 leaving the apex broadly rufo-flavous. In pattern the species 

 approaches P. eburnipennis ; the latter insect, however, beaidea
