the middle; a spine arises about the middle of the aedeagus. Length of 

 male 2.3 mm.; tegmen 3.3 mm. Length of female 2.8 mm., tegmen 

 3.5 mm. 



Described from two males and two females from Tiituila, 

 Samoa, from 760 to 1200 feet elevation. (Kellers, April and 

 December, 1918.) Type No. 1007. This insect is named after 

 the navigator who first surveyed the Samoan islands. There 

 are six specimens of females which I placed in this species 

 but have not considered as paratypes. They are darker with 

 more or less black tubercles on the tegmina. 



Urvillea dumonti sp. n. 



This genus hitherto has been represented only by one species from 

 Fiji. This species from Samoa is quite typical but specifically distinct. 



Male. Length 2.7 mm., tegmen 4.8 mm. Vertex and face dark brown 

 with carinae light, pronotum light brown, darker on lateral portions, 

 mesothorax and abdomen dark brown, legs light. Tegmina hyaline, the 

 apical cells and portion of subapical cells infuscate, veins yellow, tubercles 

 minute bearing fine, light macrotrichia ; wings hyaline, apical area fuscous, 

 veins dark. 



Anal segment large, fattened horizontally, anus at apex; pygofer 

 long ventrally, short dorsally, considerably flattened horizontally, medio- 

 ventral edge produced into a small, angular process, lateral margins 

 roundly produced; genital styles small, fiat, apex truncate, oblique, outer 

 margin slightly concave, inner margin convex slightly sinuate; aedeagus 

 complex but not dissected out. 



Described from one male specimen from Tutuila. Samoa 

 (Kellers, June, 1918), from 1200 feet elevation. Type No. 

 1008. This genus and species is named after Dumont d'Urville 

 who explored the Pacific in the Astrolabe. 



Meenoplus Fieb. 



I have not been able to procure specimens of Meenoplus 

 alhosignatus Fieb., the type of the genus, but Fieber's figures 

 and descriptions are excellent and leave little to be desired. 

 The only difference that I can find between Nisia Mel. and 

 this genus is the absence of an apical vein (M2). The claval 

 veins may join together slightly basad in Nisia and Fieber 

 shows a small vein from the second claval to hind margin 

 which does not exist in Nisia. But these differences do not
