Length, male, 14.5 to 16 millimeters (without rostrum) ; 

 width, 5.8 to 6.6. 



Length, female, 14 to 15.5 millimeters (without rostrum) ; 

 width, 6 to 6.8. 



Negros, Occidental Negros, Canlaon Volcano (Taylor, Banks, 

 Curran) . 



Twenty specimens of this very characteristic species that I 

 have examined show considerable variation in the punctures 

 and sculpture of the elytra. The hind femora are slightly longer 

 in the males than in the females. 



Metapocyrtus (Orthocyrtus) propolitus sp. nov. Plate 1, fig. 5, 2 . 



Glossy dark brownish black, with a few scattered pale blue 

 or whitish scales at sides of prothorax and elytra. Nearly 

 related to Metapocijrtus politus Heller. Rostrum with a 

 broad and strongly pronounced longitudinal groove confluent 

 with a sharply defined transverse groove at base, densely but 

 irregularly punctured, the punctures toward apex small, but very 

 coarse toward base ; front scatteredly punctured, the longitudinal 

 groove from rostrum continued but sharply defined, almost 

 reaching vertex. Sides of rostrum with a groovelike depres- 

 sion before eyes, reaching antennal scrobe. Prothorax broader 

 than long, the greatest width slightly before the middle, rather 

 uniformly scatteredly punctured. A sharply defined anterior 

 submarginal groove and a posterior submarginal groove. Lat- 

 eral margins with a few scattered pale blue or whitish scales. 

 Elytra short ovate, with irregular puncture rows, the punctures 

 coarser than in M. politus Heller. In the male the elytra reg- 

 ularly sloping toward apex, at the latter uniformly rounded, 

 as in the above species, but in the female the apex of elytra 

 forming a large and prominent triangular projection. The 

 latter is formed by two apical thornlike terminations of elytra 

 which are firmly united but still show a distinct broad groove- 

 like depression dorsally. Anterior margin of elytra in both 

 sexes slightly raised or swollen, at lateral basal angle a few 

 scattered scales and in the middle along margin another scattered 

 swarm of scales. Near apex some very fine and scattered silky 

 white hair arising from the punctures. Sides of rostrum and 

 head and legs also beset with scattered silky white hair. Meso- 

 sternum and metasternum laterally with a cluster of white 

 scales.
