INSECTS OF SAMOA. 



Samoa, Janson Coll. (two specimens) ; " Pacific, Sandwich Is., Fry Collection." 

 (This last locality is doubtless an error and should refer to the Samoan Is. 

 See remarks above by Mr. K. G. Blair and the late Dr. David Sharp.) 



The original description gives Fiji as the locality, not Togatabu (Tonga- 

 tabu) as stated in the Genera Insectorum and in Schenkling's Catalogue. 



This is the species represented most numerously in the collections. 



8. Propsephus gracilicornis, sp. n. (Text-fig. 3). 

 Female : 20-0 mm. long ; 5-5 mm. wide. 



Shiny, uniformly reddish-brown, with head and antennae darker brown. 

 Pubescence sparse, fine and moderately long. 



Head convex ; frontal margin broadly rounded ; moderately punctate. 



Antennae slender, elongate, over one-third the 

 length of the body, joints three to ten equal in 

 length ; feebly serrate. Prothorax moderately and 

 fairly closely punctate, wider than long. Sides 

 widely arcuate from posterior angles to anterior 

 margin. Posterior angles sinuate, narrower than 

 greatest width of prothorax itself, not divergent, 

 strongly unicarinate, canaliculate on posterior 

 half ; sulci divergent. Scutellum with sides nearly 

 straight ; broadly rounded posteriorly, medianly 

 carinate, coarsely punctate. Elytra as wide as pro- 

 thorax ; with wide impression near base ; parallel 

 to beyond middle ; apex rounded, briefly mucro- 

 nate at sutural angle ; striato-punctate ; intervals 

 nearly flat. Sternum darker brown than upper 

 body-surface. Mucro moderately curved behind 

 coxae. Lamina of posterior coxa (Text-fig, 4, A) 

 rounded at widest point, the outer projection not produced posteriorly as far as 

 the inner. Second and third tarsal joints strongly lamellate. 



Holotype female ; Malololelei, Upolu, 2000 ft., 22.iii.1925. Described from 

 a single specimen. 



This species is readily separable from its Polynesian congeners by its very
