Black; prothorax and elytra with golden scale spots. Very 

 closely related to P. roseomaculatus Waterh. in general body 

 form as well as in the position of the spots. Front with a scale 

 spot, prothorax with a scale spot dorsolateral^ in the middle, 

 both of which are connected discally by a transverse interrupted 

 scale line. Dorsally at base another triangular spot. Elytra 

 strongly striate-punctate, each elytron with six scale spots, of 

 which one, which takes the place of the heart-shaped sutural 

 spot of roseomaculatus, is a transverse spot located more dor- 

 solateral^. 



Length, 12 millimeters; width, 5. 



Philippines, exact locality unknown. 



Waterhouse, in his original description, 4 * mentions the pos- 

 sibility that P. striatus is only a variation of P. roseomaculatus.

This species is rather smaller than P. moniliferus, and of a narrower 

 form. It is most nearly related to P. roseo-maculatus, and very nearly 

 resembles that insect in its markings, but here they are of a golden hue, 

 and instead of the cordiform spot on the suture there are two transverse 

 spots, one on each side, at a short distance from the suture. The elytra 

 are deeply punctate-striated. On the upper surface of the thorax are 

 three spots, one behind, which is triangular, and one on each side; these 

 last are joined by a narrow subinterrupted transverse line. It is possible 

 this may only be a variety of the roseo-maculatus ; but the difference in 

 sculpture and size, as well as there being two transverse spots distant 

 from the suture in lieu of the cordiform spot on the suture, caused me to 

 separate it. In the present group, however, I have found considerable 

 difference in the sculpturing of specimens of the same species, and the 

 markings in some are subject to extraordinary variations; that is, if I 

 am right in supposing all those insects as varieties of P. orbifer which I
