lateral border, i.e. it includes the greater part of the 3rd dorsal costa, but 

 scarcely extends beyond it. That it is not a colour variety of S. acuticollis is 

 shown by slight differences in structure, e.g. the thorax is almost straight in 

 front, more constricted in the middle, and nearly as wide in front as at the base, 

 the double series of foveae of the elytral intervals are finer, and the external 

 (subhumeral) interval is wider and more irregularly punctate towards the base. 

 Moreover, the normal small form of S. acuticollis occurs also on Tutuila, and the 

 differences apart from colour, though slight, are evident enough. 



Melaneros lugubris Fairm., the type of which, as already stated, apparently 

 is no longer to be found at Hamburg, is probably intermediate in colour 

 between Samoaneros muiri and S. acuticollis, being described as " fuscus, parum 

 nitidus, subtus fusco-lutescens, . . . elytrorum costis externis pallidioribus ; ; ' 

 but it differs in having the thorax almost pentagonal.

53. Carphurus flavipes, sp. n. 



Black, with the basal six joints of the antennae, the base of the thorax, an 

 indeterminate band across the middle of the elytra, and the legs yellow. Head 

 almost impunctate, antennae slender, feebly serrate, basal joint rather short, 

 swollen, 2nd joint almost as thick, about as long as wide, 3rd and 4th succes- 

 sively narrower, thence slightly increasing in thickness to apex. Thorax about 

 as long as wide, the greatest width in front and rather strongly narrowed to 

 base ; anterior part convex, but broadly depressed behind, the base itself feebly 

 rounded and bordered. Elytra much wider at base than base of thorax, nearly 

 twice as long as together broad, the sides almost parallel, the disc strongly and
