 On the Curculionidae of the Samoan Islands (Coleoptera). 



BY GL'Y A. K. MARSHALL, D. SC, C. M. C. 



Throiii^h the kindness of Mr. F. Muir I have been able to 

 examine a small but interesting series of Curculionidae from 

 the collection of Mr. W. M. Giffard, taken by Dr. H. C. 

 Kellers, of the United States Navy, on the small island of 

 Tutuila in the Samoan Group. Very little appears to be known 

 concerning the weevils of this grouj), and the only records I 

 have been able to find are a few species described by L. 

 b'airmaire. and a short paper by Dr. K. M. llellcr on a small 

 collection made by Dr. Rechinger in 1905. 



It seemed, therefore, desirable to get together all the 

 information that was available, and I have thus added descrip- 

 tions of the Samoan weevils contained in the British Museiun, 

 which were mostly collected by the late Dr. IT. Swale in 

 1916 and 1917. 



There are four small species of uncertain generic j)osition in 

 Dr. Kellers' collection, which cannot be dealt with owing to 

 the inadetfuacy or poor condition of the material ; and Dr. 

 Heller has recorded an undetermined sjjecies of Diatlictes. 



Sl'p.family Otioriiyncijinae. 



Sphaerorhinus puncticollis sp- n. 



Color black, the elytra often partly or even wholly dark red-brown; 

 the upper surface thinly clothed with extremely flat separated transparent 

 scales, which appear as though they mifjht be moroly a sculpturing 

 of the integument; in addition tiiore are the following markings 

 formed of small round greyish-white scales : a patch on the rostrum 

 continuous with a small patch adjoining each eye; a narrow lateral 

 stripe on the basal half of the prothorax; on the elytra, a variable 

 short humeral row of about three small spots, in the middle of the 

 disk a very irregular assemblage of small spots extending from stria 

 1 or 2 to 7, a narrow sutural stripe on the declivity, and a few 

 minute spots near the apex. These markings are extremely variable, 

 reaching their highest development in the females, and being mostly or 

 entirely absent in the males. 



Male. Head with coarse i)unctures that are usually more or less
