14. Orthotylellus samoanus, sp. nov. 



Colour. — Dark reddisli, shading to fuscous ; second antennal segment, 

 rostrum except apex, and legs except hind femora, pale yellowish or slightly- 

 tinged with reddish ; outer margin of cuneus and more broadly toward apex, 

 opaque creamy white ; membrane rather uniformly pale fuscous, veins red. 



Structure. — Length 2-4 mm., width 1-08 mm. Head : width -64 mm., 

 vertex -34 mm., bluntly conical, but flattened on under side, vertex roundly 

 convex, base ecarinate, sharply and deeply margined where anterior margin of 

 pronotum fits closely ; eyes finely pubescent, raised very slightly above arcuate 

 contour of frons, juga rather full and prominent, thus carrying out the conical 

 effect ; tylus without suture at base, moderately arcuate as viewed from the 

 side ; buccula very narrow, appearing as a slender pale line. Rostrum, length 

 1-25 mm., reaching upon eighth ventral segment. Antennae : segment I, 

 length -15 mm., thickness -07 mm. ; II, -65 mm., slender, slightly thicker 

 apically, but scarcely attaining thickness of segment I ; III, -39 mm., slender ; 

 IV, -28 mm., slender. Pronotmn : length -35 mm., width at base -87 mm., 

 disc only slightly convex, lateral margins nearly straight, ecarinate, calli 

 scarcely evident. Mesoscutum moderately exposed, scutellum nearly flat. 

 Hemielytra with embolar margins slightly arcuate ; cuneus nearly triangular, 

 normally deflexed. Legs rather short, hind femora -78 mm. in length, width 

 •22 mm. ; hind tibia 1-08 mm., slender, two rows of distinct spines, without 

 spots, length of spines slightly greater than diameter of tibia. Body clothed 

 with fine pale yellowish pubescence, rather sparsely intermixed on dorsum with
