 Mulifanua, 7-16-1923, Wilder. 



In general appearance this resembles Stirellus (Phrynomorphus) hospes 

 Kirkaldy, but the pattern on the vertex is different. 



> , 19. Stirellus samoanus, n. sp. 



Head slightly wider than pronotum ; vertex about as long at middle as 

 width at base, distinctly angulate, nearly twice as long at middle as next to 

 eye ; ocelli close to the eye ; front slightly convex, sloping evenly to base of 

 clypeus ; clypeus narrowing slightly toward apex, half longer than wide ; lorae 

 large ; margin of cheek sinuate ; pronotum as long as vertex, scarcely concave 

 behind ; elytral veins distinct, claval veins united by a single cross- vein, one 

 cross-vein in disc, central anteapical cell narrowed at the middle, four apical 

 cells. 



Male, last ventral segment short, valves small, plates short (apparently with 

 broken tips) not reaching tip of pygofer. Tip of pygofer with stiff bristles 

 darkened at the tip. 



Pale straw-coloured, the apex of vertex and a line each side of the central 

 impressed line and margin at eye, figure on anterior part of pronotum and elytral 

 veins pale yellow, front pale brownish with faint yellowish- white arcs. Abdomen

 Bryan. 



This species approaches in size Stirellus {Phrynomor'phus) hospes Kirk., 

 but is slightly larger, and the picture on the vertex is distinctly different.

Head wider than pronotum ; vertex sharply angulate, length at middle 

 equal to width between the eyes ; ocelli close to the eyes ; front narrowed 

 shghtly, curved from antennae to the clypeus ; clypeus broad, narrowed slightly 

 toward the apex, half longer than width at base ; lorae narrowed below ; cheek 

 margin distinctly sinuate ; pronotum scarcely as long as vertex, shghtly concave 

 behind ; claval veins without cross-vein, one cross- vein on the disc.
