Elytra with irregular double puncturation, the larger punctures very shallow, 

 the interstices shining, with scattered, very fine punctures. 

 Length : mm. 



Tutuila : Pago Pago, 9.ix.l923, 2 examples (Swezey and Wilder). 

 (Paratype in Bishop Museum, Honolulu.) 



Allied to C. pacificus Sharp, which it resembles in the form of the head and 

 in the puncturation both of the thorax and elytra, except that, in the case of 

 the larger punctures of the elytra, there is less tendency to seriate arrange- 

 ment. It differs, however, in the shape of the elytra, which in C. pacificus are 

 parallel-sided for about two-thirds of their length, then very bluntly rounded 

 at the apex. In C. tutuilensis, they are more rounded at the sides, widest about 

 the middle, thence sharply narrowed to form an acutely rounded apex. Still 

 more closely allied is C. cheesmanae, recently described by me * from a specimen 

 from the Marquesas Is., but the latter is larger and more robust, with the sides 

 of the thorax more strongly rounded and more narrowly reflexed. From the 

 European C. nitidus Hbst., it differs more widely in having the side borders of 

 the thorax more strongly reflexed and completely visible when the insect is 

 viewed from above. 



Scolytocis, gen. no v. 



Antennae 9- jointed, 3rd joint long and slender, 4th very small, 5th and 

 6th submoniliform, 7th and 9th forming a short compact club. Tibiae sparsely 

 and finely denticulate on outer side. 



Genotype, S. samoensis, sp. n. 



A peculiar genus, resembling Tropicis Scott (Trans. Linn. Soc, xix, p. 30, 

 Fig. 3, 1926) in the short antennae with broad compact club, and also in the 

 denticulations of the outer edge of the tibiae. From Tropicis, however, the 

 present genus differs in there being one joint less in the funiculus of the 

 antennae, and in the non-carinate elytra. The tarsi appear to be 3-jointed, 

 though there may be a minute basal joint. 



41. Scolytocis samoensis, sp. n. 



Testaceous, glabrous, moderately nitid. Head with the supra-antennal 

 lobes little developed, not reflexed, not more prominent than the clypeus
