,.6 . , . INSECTS OF SAMOA. 



shoulders square, sides very nearly parallel, though widest at apical third, 

 slightly sinuate behind, truncate at apex, the truncature a little emarginate, 

 the sutural angle with a small mucro ; striae fairly deep, deeper and rather 

 irregular close to apex, finely and closely punctate, a moderately long scutellary 

 striole, 5 deeper than the others near base ; intervals rather flat, 7 and 8 very 

 narrow and carina te near apex, curving round behind the others to apex, mar- 

 ginal channel containing two fine raised parallel lines, the inner one inter- 

 rupted by the series of umbilicate pores, interval 3 tripunctate, first pore at a 

 fourth, adjoining stria 3, second and third at three-fifths and near apex respec- 

 tively, adjoining stria 2, surface smooth, with two slight depressions on disk 

 on each side, one at about middle, the other before apex. The microsculpture 

 consists in extremely fine transverse lines, which form a reticulation of strongly 

 transverse meshes, clearly visible on elytra, faint on head and prothorax. 

 Sterna and middle of venter practically smooth, sides of venter very finely 

 rugose, metepisterna elongate. All tibiae and tarsi bisulcate, but protarsi 

 much less evidently so, the metatarsi with a carina between the sulci ; joint 

 4 of tarsi moderately bilobed, in metatarsi the outer a little longer than the 

 inner lobe, 5 not ciliate beneath. 



The species should be placed quite at the end of Chaudoir's table. It is 

 very closely alHed to C. bennigseni Sloane, of New Guinea, of which Dr. Horn 

 has kindly sent me the type for comparison, and agrees entirely in the combina- 

 tion of unusual characters mentioned by the author of that species at the end 

 of his description, viz. " wide bisulcate tarsi, the 8th interstice narrowly carinate 

 on the apical curve, and the 9th interstice narrow and interrupted by its seriate 

 punctures." It dift'ers in its smaller size, lighter legs and antennae, and green 

 instead of greenish-blue elytra ; prothorax with wider marginal channel ; 

 elytra with the striae deeper and more evidently punctate, the apex with a 

 very small instead of a stout mucro. 



Upolu : Malololelei, 2000 ft., 25.ii.1924, 1 example ; a second example, 

 also from the same locality, vii.1925 (Wilder, Bishop Museum). 



8. Colpodes pacificus, sp. n. 

 Length: 12-0 mm. Width: 4-1 mm. 



Piceous : elytra dark green, side margins of prothorax, apical border of 

 elytra, tibiae, and tarsi brown (Text-fig. 4). 



Head moderately convex, neck slightly constricted, surface smooth, frontal
