One male and one female from Raoul Island (Sunday Island), Kermadec 
Micromasoria raouli n. sp. 
d. Brachypterous ; length, 4-6 mm. ; tegmen, 1-7 mm. Tegmina reach- 
ing posterior margin of fourth abdominal tergite. In structure close to 
M. caelata (White), basal segment of antenna slightly flattened and face 
slightly broader; the five mesonotal carinae distinct; hind tibiae with 
four spines. 
Clay-colour or tawny olive; face speckled with lighter dots; middle 
and front legs banded with darker-brown bands, clypeus dark brown, some 
large, anal angles obscure, not produced ; anal segment large, filling up 
greater part of opening of pygofer and hiding aedeagus, lateral margins 
curved round ventrad and meeting together at apex; genital styles subawl 
shape, slightly curved. 
9. Brachypterous ; length, 5-4 mm. ; tegmen, х olo 
similar to male. Ovipositor curved, projecting slightly beyond apex of 
abdomen. 
n a full-grown male nymph the antennae are comparatively slightly 
shorter and thicker. 
Described from one male, one female, and a nymph from Raoul Island 
(Sunday Island), Kermadec Archipelago. The species is named after the 
officer who first sighted the island and after whom the latter is named. 
Types in Dominion Museum, Wellington. 
The genus Micromasoria is closely allied to Ugyops, and it will be difficult 
to keep the two separated. ae 
These specimens were all from the W. R. B. Oliver expedition to the 
Kermadecs in 1908, and were collected by Mr. W. L. Wallace.
