pronounced form in a series of local forms or races, most of 



which are connected up through intermediate forms. 



The general distribution of this species and its local races is 

 mainly between 13° and 15° north latitude, in central and 

 southern Luzon, Polillo, Mindoro, and Catanduanes and reaches 

 in a southeasterly direction to Samar.

 Larger than typical P. moniliferns Germ., prothorax laterally 

 more rounded, elytra more oblong-ovate. The lines on pro- 

 thorax and elytra not interrupted and much broader, forming 

 stripes. The coloration of the markings yellowish or greenish 

 golden. Rostrum with an oblong scale spot which reaches above 

 front. Prothorax, the longitudinal line is more wedge-shaped 

 and reaches only to the cross line in the middle. The dorsal 

 longitudinal stripes on elytra in basal half are confluent witn 

 the crossband, those in apical half not quite reaching the latter. 

 Male, length, 11 to 13.5 millimeters (without rostrum) ; width, 

 4.8 to 6. Female, length, 13 to 14 millimeters (without ros- 

 trum) ; width, 6 to 6.5.

In P. concinnus Waterh. the rows of punctures on the elytra 

 are more distinct, the longitudinal stripes are broader and some- 

 what divergent at base. The coloration of the markings is 

 very pale green. 

 Samar, Borongan. 



Var. jagori Heller has the longitudinal marking on the pro- 

 thorax strongly pronounced wedge-shaped. On the elytra in 

 the apical half are two small oblong spots.
