Glossy dark green, prothorax and elytra with pale greenish 

 crossbands. Rostrum in apical half strongly bulging, basal half 

 with a rather shallow impression and a longitudinal groove. 

 Prothorax slightly broader than long, subglobular, with a cross- 

 band in the middle which is narrow discally, becoming wider 

 toward lateral margins. Elytra with very regular, strongly pro- 

 nounced rows of punctures and a crossband near base, another 

 slightly broader at middle ; both these bands are interrupted at 

 suture and the second is curved on the side of elytra and runs 

 backward along margin. Each elytron in apical third with a 

 large oblong spot parallel to suture and two smaller, more 

 roundish spots laterally. 



Male, length, 12.5 millimeters (without rostrum) ; width, 5.8. 



Philippines, exact locality unknown. 



The description is taken from a specimen loaned by the 

 British Museum. 



Pachyrrhynchus latifasciatus Waterh. represents a somewhat 

 isolated species of the genus, but seems to be most closely related 

 to some of the P. speciosus group. 



GROUP III 



Group III comprises two of the extra-Philippine species, 

 Pachyrrhynchus morotaiensis Vollh. and P. forsteni Vollh. Both 

 species are quite different from any of the Philippine groups, 

 but come closest in general appearance to some of the P. monili- 

 ferus group. 



Key to the species of Pachyrrhynchus, Group III. 

 a 1 . General color bluish black. Elytra with white scale spots forming 

 cross rows. The spots in the middle row approaching each other 

 very closely, thus forming an interrupted crossband. 



P. forsteni Vollh.
