metasternum with a scale spot laterally. Penis structure, Plate 

 3, fig. 33. 



Male, length, 9.5 to 13 millimeters (without rostrum) ; width, 

 4.5 to 5.6. Female, length, 12.5 millimeters (without rostrum) ; 

 width, 6. 



Mindanao, Surigao Province, Surigao. Dinagat (my col- 

 lector). Leyte, Cabalian (Gregorio Lopez). One specimen, 

 from Leyte, has the general color of the elytra reddish coppery. 



Specimens from the first two localities here given I consider 

 typical, since they agree perfectly with the Waterhouse de- 

 scription, particularly with this author's remark that "it may be 

 distinguished from either of the other species by its brass green 

 color." Heller placed P. eschscholtzi Waterh. as a synonym 

 of P. erichsoni, under the impression that it represented the 

 female of P. erichsoni. I cannot agree with this since both 

 sexes of the last-named species show the same general coloration, 

 the same number of spots, as well as other small but constant 

 differences in the form of the prothorax and elytra in com- 

 parison to P. eschscholtzi. Furthermore, the penis structures 

 show that this organ in P. erichsoni is broader toward the 

 point. For these reasons P. eschscholtzi is to be considered 

 as a well-distinguished local race or subspecies of P. erichsoni 

 Waterh.

 Black; prothorax glossy. Each elytron with eight to ten 

 yellowish green or pale flesh-colored scale spots. Two form a 

 cross row at base, two or three in the middle, three or four in 

 apical fourth, and one near apex. 



Male, length, 10 to 10.5 millimeters (without rostrum) ; width, 

 4.8 to 5. Female, length, 12.5 millimeters; width, 5.8. 



Luzon, Laguna Province, Paete, Mount Banahao. Polillo 

 (Schultze) . 



Var. chrysocompsus Heller has the dorsolateral spots of pro- 

 thorax modified, forming reverse comma-shaped spots, the 

 pointed end being slightly curved. 



Pachyrrhijnchus erichsoni and subspecies eschscholtzi seem 

 to have the largest range of distribution of any species of the 

 genus. It seems probable that further local races of P. erich-
