STAPHYLINIDAE. 



23 



Colour of P. pennifer Fauv., but smaller and narrower, the antennae 

 shorter, the penultimate joints obviously shorter, though longer than broad ; 

 would appear to be near P. philippinus Bernh., but to differ in colour. Head, 

 with eyes, a little broader than the thorax, coarsely and closely punctured. 

 Thorax slightly broader than long, the sides practically straight and convergent 

 posteriorly, before the middle of the base with a short impunctate elevation 

 with a depression on either side, rather coarsely and closely punctured like the 

 head. Elytra about times longer than the thorax, closely, coarsely rugulosely 

 punctured. Abdomen with the usual imbricate sculpture. 



Savaii, 9.V.1924, and rain forest, 2000-4000 ft. above the sea (Bryan). Two

10. Palaminus, n.sp. 



Upolu : Malalolelei, vii.1924. One defective example. 



11. Medon tutuilanus, sp.n. 



Sub-depressed, rufo-ferrugineous, moderately shining. Elytra reddish- 

 testaceous, with indeterminate brown fascia of varying breadth. Abdomen 

 brown, the posterior margins of the last two segments broadly testaceous. 

 Antennae and legs reddish- testaceous. Length 3-5 mm. 



Colour of Ophiomedon incomptus Shp., but the thorax broader, this and the 

 head more finely punctured. Narrower than M. opacellus Fauv. and more 

 depressed, the temples straighter and the posterior angles more briefly rounded, 

 the thorax shorter and broader, the puncturation simple and the colour of the 

 elytra different. Head as broad as long, square, a little broader than the thorax, 

 temples parallel, practically straight, the posterior angles briefly rounded, the 

 base feebly emarginate, closely and moderately coarsely punctured, with a small 

 impunctate space on the vertex. Antennae rather short, the 7th to 10th joints 

 transverse. Thorax distinctly transverse, trapezoidal, before the base with a 

 short, median, impunctate keel and short impression on each side ; puncturation 

 very similar to that of the head. Elytra short, one-third longer than the thorax, 

 closely, rather finely, asperately punctured. Abdomen rather closely and 

 rather finely punctured, finely and moderately closely pubescent.
