INSECTS OF SAMOA. 



inverted V, decrease in size posteriorly, and lie one against the other or 

 even telescope into one another ; the greater part of the surface of the sixth, 

 seventh and eighth, especially in the female, bears wax glands and, in the female, 

 long wax filaments. The general facies, the granulated clavus and Sc + R, 

 and, in many species, the median ocellus, all distinguish this family from 

 others. In view of the fact that the species, as well as the genera, are all closely 

 related one to another, the study of the male genitalia is essential to the correct 

 understanding of the species and, perhaps, of the genera also. 



■ - ■ Nisia Melichar 



^ - 32. Nisia atrovenosa (Lethierry) 



Upolu : Apia, three specimens, 28.V.1925 (Buxton and Hopkins) ; one 

 specimen, 13.ix.23 (Swezey and Wilder).

 A long series from various localities. 



Tutuila : Amauli, fifty-nine specimens, from Cyrtandra, 6.ix.l923 ; Pago 

 Pago, ten specimens, 9 and 30.ix.l923 ; Fagasa, one specimen, 9.ix.l923 (Swezey 

 and Wilder).

 Previously known to be found in Tutuila. 



. Suva Kirkaldy 



34. Suva upolensis sp. n. Figs. 14, 15. 

 Male ; length 2 mm. ; tegmen 3-3 mm. 



In build and colour similar to Suva Jcoebelei Kirk. At base of vertex two 

 small acute triangles, which by some are considered to represent the vertex ; 

 no median carina on vertex or frons. First claval vein heavily granulate, 

 Sc + 11 without granules. Median ocellus present but obscure. 



The genitalia figured ; they differ considerably from those of ;S. koebelei. 



Light yellow, heavily covered with white, powdery, waxy secretion, eyes
