CAEABIDAE.

bisulcate ; joint 4 of tarsi moderately bilobed, the outer lobe in metatarsi a little 

 longer tban the inner one, 5 not eiliate beneath. 



The present species does not seem nearly related to any other ; it will come 

 near the end of Chaudoir's table and be readily distinguished from the other 

 Samoan species by its brown colour, which is unusual in the genus.

10. Colpodes piceus, sp. n. 



Length : 8-5 mm. Width : 3-3 mm. 



Piceous, very shiny : palpi, antennae, and legs more or less ferruginous. 

 (Text-fig. 6.) 



Head moderately convex, no neck constriction, smooth, frontal foveae 

 small and inconspicuous, clypeal suture very faint, but ending on each side in 

 a minute rounded pore, antennae of medium length, 

 joint 3=4. Prothorax convex, a third wider than head, 

 nearly t^dce as wide as long, extremities finely bordered, 

 base truncate, with its sides sHghtly oblique, much 

 wider than apex, front angles strongly rounded, sides 

 finely bordered, explanate, rounded but not reflexed in 

 front, practically straight behind, bisetose, the hind 

 angles obtuse, reflexed, and not much rounded ; median 

 line and transverse impressions distinct but shallow, 

 basal foveae small, rounded, and fairly deep, surface 

 practically smooth. Elytra fairly convex, oval, two- 

 thirds wider than prothorax, and three-quarters longer 

 than wide, widest at middle, sides evenly rounded, 

 strongly sinuate behind, narrowly truncate at apex, with a sharp mucro 

 at each sutural angle ; striae fine and minutely punctate, very faintly im- 

 pressed, more deeply — especially 7 — close to apex, 8 fairly deep throughout ; 

 intervals flat, 8 very narrow and carinate behind, curving round behind the 

 other intervals to near apex, 3 with three rather small pores, first at a fourth 

 adjoining stria 3, second and third at a half and three-fourths, adjoining stria 2, 

 surface smooth and without depressions. Microsculpture of elytra consisting 

 of very fine, closely placed, transverse lines, which form irregular, very wide 

 meshes, just visible on the prothorax, but hardly so on the head. Under side
