This remarkable species I place for the present in the P. 

 moniliferus group. It is easily recognized by the very dis- 

 tinctly subspheric prothorax, very short ovate elytra, and pe- 

 culiar coloration. The legs, particularly the tibise, are also 

 relatively longer than in any other species of this group but 

 not so slender as in species belonging to the P. anellifer group.

Black; moderately glossy, with metallic pale green (male) 

 or coppery micaceous (female) scale markings. Related to P. 

 phaleratus Waterh. Rostrum toward apex strongly .divergent, 

 in apical half scatteredly punctured, in basal half with a strongly 

 pronounced triangular depression beset with a large scale spot. 

 Front with a triangular spot and sides of head with another 

 spot. Prothorax a little broader than long, very minutely and 

 scatteredly punctured. A crossband, which is sometimes in- 

 terrupted before the middle, branches laterally, one branch 

 running obliquely toward the anterior and the other toward 

 the posterior margin, both are continued as a lateral marginal 

 stripe and circumscribe the sides. Dorsally in the middle at 

 hind margin a large oblong triangular spot. Elytra in the male 

 oblong, in the female short ovate, the surface very finely coria- 

 ceous with very faint traces of puncture rows. A broad 

 irregular crossband in the middle, dorsally in basal half an 

 abbreviated stripe which is continued as a broad basal and 

 marginal stripe to apex. At the latter place it is expanded as 

 a large patch, especially in the female, from which a narrow 

 longitudinal stripe extends forward to crossband. The female 

 mostly has in apical half of elytra an interrupted subsutural 

 stripe. Underside, mesosternum, metasternum, and first abdomi- 

 nal stemite laterally with a scale spot. Femora with a ring 

 spot near apex, interrupted above. Penis structure, Plate 3, 

 fig. 25. 



Male, length, 13.6 millimeters (without rostrum) ; width, 6. 

 Female, length, 17 millimeters (without rostrum) ; width, 7.8. 



Mindoro, subranges of Mount Halcon. 



This species is variable in respect to the markings. In the 

 male the longitudinal stripe in apical half of each elytron is 

 abbreviated and does not reach to crossband.
