INSECTS OF SAMOA. 



smooth, metepisterna elongate. Tibiae bisiilcate, but not carinate ; meso- 

 and metatarsi feebly bisulcate ; joint 4 of all tarsi strongly bilobed, outer lobe 

 much longer than inner one in two hind pairs of legs, 5 not ciliate beneath. 



Similar in size and colour to C. lafertei Montrouzier, but with a wider and 

 smoother prothorax, the elytra much more finely striate and strongly mucronate.

; - . 11- Colpodes anomalus, sp. n. 



' Length : 8-5 mm. Width : 2-75 mm. 

 Black, shiny : palpi, joints 1 and 2 of antennae (rest brown), and legs 

 ferruginous. (Text-fig. 7.) 



Head convex, with a moderate neck constriction, smooth, frontal foveae 

 short, fairly deep, and a little uneven, eyes rather small and flat, somewhat 

 enclosed behind by the genae, antennae long and slender, 

 joint 4 slightly longer than 3. Prothorax moderately con- 

 vex, quadrate, slightly wider than head and also slightly 

 wider than long, base truncate, its sides slightly oblique, 

 a little wider than apex, which is faintly emarginate, sides 

 narrowly bordered and reflexed, bisetose, gently rounded 

 and barely sinuate before base, the hind angles slightly 

 obtuse, reflexed, but not rounded ; median line and front 

 transverse impression both clearly marked, basal foveae 

 fairly deep, diverging in front and continued forward on 

 each side shallow linear impression, parallel with 



margin, surface smooth, the basal area a little uneven. 

 Elytra flat, over two-thirds wider than prothorax, barely 

 as much longer than wide, sides strongly rounded, faintly sinuate behind, 

 narrowly truncate at apex, the truncature emarginate on each side, outer 

 tooth blunt, a little longer than inner one, which forms a small mucro ; 

 striae fine and very clearly excised, impunctate, outer shallower than inner 

 ones, all a little deeper close to apex ; intervals flat, 3 tripunctate, first 

 pore at a fifth, adjoining stria 3, second and third at a half and four-fifths, 

 adjoining stria 2, surface smooth, with a slight depression at each side on 

 basal half. Microsculptm'e of the elytra consisting of very fine closely 

 placed lines, forming very wide meshes ; on the prothorax the lines are 

 finer and fainter ; on the head there is a reticulation of isodiametric meshes.
