confluent coarse rugosities beset with reddish golden scales 

 having a luster like mother of pearl. Elytra finely coriaceous, 

 very indistinctly striate-punctate, basal and apical fourths with 

 coarse rugosities beset with scales. Mesosternum and meta- 

 sternum and first abdominal segment with a scale patch later- 

 ally. Femora with a scale spot near apex. Penis structure, 

 Plate 3, fig. 30. 



Male, length, 8.5 to 12 millimeters (without rostrum) ; width, 

 4.5 to 5.5. Female, length, 12 to 12.5 millimeters (without 

 rostrum) ; width, 6.2 to 6.6. 



Luzon, Zambales Province, Iba : Bataan Province, mountains 

 of Mariveles (Schultze). 



In the var. crucifer Heller, the scaled rugosities on prothorax 

 dorsally are somewhat concentrated so as to form a figure ap- 

 proximately like a ^. The var. aurinius Heller refers to a per- 

 fectly fresh specimen in which the scales possess in a marked 

 degree the peculiar color and luster of mother of pearl. This 

 coloration, as well as a certain opalescent sheen of the scale 

 markings of many other species of the genus, mostly disappear 

 owing to post-mortem changes. 



Pachyrrhynchus sphaericollaris sp. nov. Plate 3, fig. 7, S (lateral 

 view) ; Plate 6, fig. 12. 



Very glossy, dark purplish coppery, without any scale mark- 

 ings. Apical half of rostrum strongly swollen, basal half flat 

 depressed, with a very shallow triangular depression and a 

 strongly pronounced medial groove reaching to front. A small 

 patch of short creamy white hair at sides of head below eye. 

 Prothorax slightly broader than long, subspherical, glossy and 

 impunctate, except a small depression with a few scattered and 

 rather coarse punctures in the middle at each lateral margin. A 

 well-pronounced anterior submarginal groove. The marginal 

 area set off by the latter slightly swollen. Elytra very short 

 ovate, dorsally and laterally strongly and uniformly inflated, 

 with almost obsolete rows of punctures dorsolateral^. A well- 

 pronounced submarginal puncture row from middle to apex, 

 the punctures getting coarser near apex. Near the latter 

 two other abbreviated coarse puncture rows also strongly 

 pronounced, forming groovelike impressions, the interstices 

 forming swollen ridges. Underside and tarsi bluish black. 



Male, length, 13.5 millimeters (without rostrum) ; width, 6.5.
