If, lat. \-^^j lines. 



Of this species I have seen 4 examples, and do not find much 



variation in their colouring and pattern: the markings in some 



being, however, of deeper colour than in others and some of the 



elytral spots which are isolated in some examples being obscurely 



connected together in other examples. The peculiar sculpture of 



the pro thorax is described under the heading of the preceding 



species (P. Pandora). This insect is remarkably like P. de^icatula, 



Chp., (in subgroup iv. ), but differs from it by its larger size, 



elongated head, and pro thoracic sculpture, — the prothoracic 



sculpture of delicatula being of the same kind as that of the other 



species of this subgroup.
