23,6 Schultze: Pachyrrhynchus (J41 



The general scale coloration in these specimens is either pale 

 or dark violet, pale green or bluish green, or pale reddish brown. 

 In the neighborhood of Baguio, Benguet Subprovince, I collected 

 many specimens which have pale green or light blue scale colora- 

 tion ; also some examples in which the general markings are pres- 

 ent in only a fragmentary way, being in some instances reduced 

 to more or less interrupted bands, lines, or spots (Plate 6, figs. 

 10, 11). Some of the last-mentioned varieties bear a strong re- 

 semblance to P. moniliferus Germ. 



Another rather strongly fixed local race I designate as— 

 Pachyrrhynchus orbifer subsp. gemmans Chevr. Plate 6, fig. 9, $ . 

 Black, shiny, the scale markings brilliant golden, coppery red 

 or green, glittering like precious stones. Prothorax with a broad 

 crossband which widens at the sides. Elytra regularly and 

 strongly punctate-striate. The bare areas more or less con- 

 fluent with each other, forming a crossband, sometimes con- 

 fluent along suture. Femora with the usual spot at middle and 

 near apex. 



Male, length, 10.5 to 13 millimeters (without rostrum) ; width, 

 4.5 to 6. Female, length, 11 to 13 millimeters (without ros- 

 trum) ; width, 5 to 6.5. 

 Luzon, Cagayan Province, Tuao, Rio Chico {Baker) . 

 Another rather striking form of P. orbifer subsp. gemmans 

 Waterh. is— 



Pachyrrhynchus orbifer subsp. gemmans var. ardens Chevr. Plate 6, 

 fig. 5, s. 

 Black, the scale markings of a brilliant pale flesh-colored hue. 

 Luzon, Cagayan Province, Sanchez Mira (Schultze). 

 Still another rather isolated form is — 

 Pachyrrhynchus orbifer subsp. azureus Schultze. Plate 1, fig. 2 

 (lateral view) ; Plate 5, fig. 11. 

 Black; prothorax and elytra with lapiz lazuli crossbands. 

 Front with an oblong scale spot. Prothorax with a crossband 

 which becomes very broad at sides. A wedge-shaped scale spot 

 extends from discal area to hind margin. Elytra indistinctly 

 punctate-striate. Each elytron with a large crossbandlike scale 

 spot at base, not quite reaching suture, another in the middle, 

 and another in apical third. The last-mentioned spot is con- 

 nected along margin with the spot in the middle. 



Male, length, 12 millimeters (without rostrum) ; width, 5.6. 

 Luzon, Benguet Subprovince, Kabayan (Schultze).
