Black; head, prothorax, and legs glossy, elytra rather dull. 

 Prothorax and elytra with pale greenish golden bands and 

 stripes. Rostrum, basal half dorsally strongly but flattish de- 

 pressed with a large bifid scale spot and a medial groove, the 

 latter reaching to front. Prothorax with a scale band at ante- 

 rior and posterior margins, both of which are connected by a 

 lateral marginal longitudinal stripe. Toward each side, dorso- 

 laterally, a longitudinal stripe reaching from base to near ante- 

 rior margin. Elytra finely coriaceous, coarsely and regularly 

 punctate-striate ; in the third interstice a medially interrupted 

 stripe, confluent at base with a lateral marginal stripe, the latter 

 continued to apex and confluent again with the abbreviated 

 stripe of the third interstice. A rather broad transverse band 

 in the middle confluent with the marginal stripes. In apical 

 half in the fifth interstice a small roundish spot and in the 

 seventh interstice an elongate spot. Femora with a small spot 

 near apex. 



Male, length, 13 millimeters (without rostrum) ; width, 6.6. 



Libucan Island near Samar (A. Celestino). 



This species resembles superficially certain forms of P. moni- 

 liferus chevrolati, but is readily distinguishable from the latter 

 by the peculiarly shaped rostrum and distinctly different mark- 

 ings on prothorax.

 Black with greenish yellow scale stripes. Rostrum dorsally 

 in the middle with broad strongly pronounced transverse groove 

 and another indistinct groove at base, each groove beset with 

 two small scale spots. Both transversal grooves are connected 

 by a narrow and sharply defined longitudinal medial groove. 

 Sides of rostrum and head with a scale spot. Prothorax as 

 long as broad, dorsally before the middle with a transverse line 

 which branches dorsolateral!^ one branch extending to the an-
