M ■ - i : INSECTS OF SAMOA. 



specimens under consideration include representatives of three more species ; V. 

 stevensoni and F. hopkinsi, of Samoa, and another new species found in Tonga. 

 So far as present knowledge goes, this appears to be a South Pacific genus straying 

 into Australia. The male genitalia are peculiar in having the genital styles 

 amalgamated into a single asymmetrical structure with a process on the left 

 side, and in having the anal segment fastened to the pygofer so that it possesses 

 little or no movement.

30. Vanua stevensoni sp. n. 

 Male ; length 5-3 mm. ; tegmen 7 mm. 



In build similar to F. poyeri but smaller. The left anal angle of pygofer 

 is rounded and curved inward, the right angle is shghtly produced and curved 

 inward ; the anal segment on the right with the under side near middle produced 

 into an angular projection. Light green, turning to stramineous in older cabinet 

 specimens ; carinae of vertex shghtly tinged with red. Tegmina hyahne, veins 

 green, commissure from angle to apex of clavus black ; second claval vein red 

 extending to hind margin beyond clavus. Wings hyaline with stramineous veins. 



Upolu : Described from two male specimens, one from Vailima, 19. x.1925, 

 and one from Malololelei, 2000 feet elevation, 23.xi.1924 (Buxton and Hopkins). 



There is one damaged female from Malololelei, which has the dark mark 

 along the commissure ; the insect appears to belong to this species, but since it 

 is without a head I do not include it in the type material : in this specimen
