INSECTS OF SAMOA. 



Soc. Agric. Lyon, vii, 1855, but usually the separate issue of the Faune de Vile 

 de Woodlark, 1857, is quoted. 



The series obtained well illustrates the great variability in size usual in 

 this species, the smallest specimen (a $) measuring in a straight line from the 

 anterior margin of the pronotum to the apex of the pygidium 5-5 mm., and 

 the largest (a ^) 15 mm. 



A series from Upolu : Apia, ii., hi., iv., v., vi. ; also obtained by J. S. 

 Armstrong, hi. 1924. Tutuila : Pago Pago, ix. 1923 (Steffany). 



Notiana, gen. nov. 



Near Sintor Schoenh., 1839. Proboscis with five dorsal carinae ; its apical 

 margin with broad shallow sinus. Labium not divided into two distinct lobes. 

 Antennal grove foveiform. Antenna not reaching middle of prothorax. 



Genotype : N. buxtoni, sp. n. Here also belongs Sintor superciliaris Jord., 

 1895, of the Philippines. 



2. Notiana buxtoni, sp. n. (Text-fig. 1). 



Robust, dark brown, here and there rufescent, variegated with grey 

 and yellowish pubescence, minutely coriaceous, with no distinct punctures 



apart from the rows on the elytra. 



Proboscis a little longer than it is apically 

 broad, median carina nearly reaching to apex, 

 divided at base and continued as two carinae across 

 frons, the groove between these two carinae re- 

 duced on occiput to a narrow channel ; the lateral 

 carinae abbreviated ; middle of under side of pro- 

 boscis cariniform ; area between gular sinus and 

 antennal groove bicarinate, the depression between 

 these two ridges continuous with a groove situated 

 at some distance from the base of the gular sinus. 

 Frons broader than half the rostrum, both grey, 



occiput for the greater part brown. Distal seg-

proboscis, head. ments of antenna paler brown than proximal ones, 



segment 3 nearly as long as 4th and 5th together, 



4th to 8th gradually decreasing in length, 8th about twice as long as apically
