by the punctuation of its striae ; the punctures are separated, 

 with an inten-al between them of four or five times their own 

 breadth, whereas in P. lineolata they are much closer. 



A single example from M. Chevrolat's collection, from the 

 Cape.

This species, in the form and pattern of its markings, entirely 

 differs from P. picturata, Chev. ; and, independently of ita mark- 

 ings, may readily be recognized by the close arrangement of 

 striated punctures on its elytra. 



A single example from the collection of M. Chevrolat.

 Syst. El. i. 426. 22. 



This pretty speciea maybe briefly characterized as aeneo-piceous, 

 with four darkly rufous bands on the elytra between alternate 

 strise : it seems to vary somewhat in size, but not in pattern, 

 and to be not uncommon at the Cape. I have received it from 

 the Continent, and also from Mr. Stevens. 



In Mr. Baly^s collection, that of Mr. Wilson Saunders, and 

 my own. 



In Fab. Syst. £1. this species is inaccurately registered aa 

 from the American islands.

 datis et tenuiter marginatis, disco subtiliter (margines versus for- 

 titer) punctato, aeneo-nigro ; scutello laevi, aeneo-mgro ; elytris for- 

 titer punctato-striatis (punctis crebris, ordine dispositis et sat pro- 

 fundis), aeneo nigris, vittis tribus undique flavis (1"* inter strias 2.
