Tropiduchidae. 

 Vanua poyeri sp. n. 



Male. Length 7.3 mm., tegmen 10.5 mm. Vertex slightly longer 

 and more pointed at the apex and the face slightly longer and nioro 

 pointed at the base, otherwise typical of the genus. 



Male genitalia asymmetrical; pygofer deeply and angularly emarginate 

 on ventral edge, lateral margins angularly produced, the right side more 

 acutely, the left side with the angular production turned inward; 

 anal segment symmetrical, large, long, fairly narrow, widened and 

 rounded on apical half, apex rounded, anus about one-third from apex; 

 only one median genital style, much longer than broad, sides subparallel, 

 apex with slight emargination in middle, a large curved spine arises 

 from left side about middle; penis long, slender cylindrical, with 

 slender apex, jointed about one-fourth from apex, there is a membrane 

 capable of expansion on apical third. 



Light oriental green to straw color or light brown, in some specimens 

 carinae slightly tinted with red; abdomen brownish. Tegmina and 

 wings hyaline, veins light green, stramineous or light brown. 



Female. Length 8.5 mm., tegmen 9.5 mm. Pregenital plate straight 

 on hind margin with a semi-circular patch in middle of hind margin 

 with a different texture to the rest of the sternite; anal segment 

 semi-conical, the apex larger than base, ventral apical edge roundly 

 produced. In color similar to male. 



Described from eight males and seventeen females from 

 Tntuila, elevation 900 to 1200 feet (Kellers, June, July, 1918). 

 Type No. 1019. This species I have named after Captain J. 

 M. Foyer, Governor of American Samoa. 



Vanua angusta. sp. n. Fig. 15. 



Male. Length 7 mm., tegmen 6.5 mm. Length of vertex slightly 

 greater than width (1.2 to 1), widest just anterior of eyes, from where 

 it narrows to a pointed apex; the face equally elongated and pointed at 

 base, the diagonal carinae on face reaching to anterior margin of eye, 

 as in the type species. In all other respects similar to genotype. 



Genitalia asymmetrical; pygofer similar to V. poyeri, but the projec- 

 tion on right side flat, broad, bent at right angles and with slightly 

 rounded apex, that on left side small, narrow with rounded apex, anal 

 segment long, narrow, apex pointed with a large, curved spine beneath 

 pointing basad, anus about one-third from apex; the single median 

 genital style broad, subparallel sided, apex truncate with two small 

 emarginations, a curved spine arises on left edge slightly apical of middle; 

 penis long, cylindrical, with apex developed into a small, round process 

 beset with small teeth and large, semi-membraneous process, broad 

 at base and pointed at apex with two rows of small teeth.
