mark on the upper half of the base of the mandibles ; the apical half piceous, tinged with 

 yellow at the base of the mandibles. The antennae are formed pretty rrruch as in the Q ; 

 they are rufous below towards the apex. In both sexes there is a more or less distinct 

 yellowish mark between the antennae. The 4 front coxae are largely yellow below. 



This species cornes near to /. morosa Smith from Waigëu, but the description is not 

 précise enough to enable me to identify Smith's species. My species is certainly not the 

 Icaria morosa described by Mr. W. A. Sci-IULZ, Berlin. Ent. Zeitschr. XLIX, p. 226. 



The size of the yellow marks on the 9 clypeus and of the black one on the c 7 varies. 

 In one Ç the band on the 2 nd abdominal segment is absent. 



5. Icaria irritata Smith. 



Proc. Linn. Soc. 1863, p. 6. 



A spécimen from Manokwari, May, is probably this species, which was described from Misol. 



At any rate it agrées with Smith's colouration description. It (the Ç) is covered with 

 a dense grey pile; there is a narrow furrow on the scutellum, a conspicuous pyriform dépres- 

 sion on the centre of the metanotum, the broad end being above ; the sides are obliquely 

 sloped ; and there is a distinct furrow down the centre. The alar nervures and stigma are 

 rufo-testaceous. The abdominal pétiole is about one half longer than it is wide at the apex; 

 it is narrow at the base, becoming gradually wider towards the apex; above it is roundly 

 curved from the base to the apex. The base of the 2nd abdominal segment is broadly brow- 

 nish on the sides. 



The affinities of this species are with /. australis, it having the same form, gênerai 

 colouration and structure of abdominal pétiole. /. australis is easily known from it by the 

 alar stigma and nervures being black and, more particularly, by the sides of the metanotum 

 projecting in the middle into stout tubercles, while in irritata, they hâve a graduai slope 

 from the base to the apex. 



Rhynchium Spin. 



1. Rhynchium haemorrhoidale Fab. 



This species is represented by the race médium Maindron, Ànn. Soc. Ent. de Fr. 1S79, p. 

 278 from Manokwari; and race perentissium Sauss. from Humboldt Bay and Manokwari. May 

 and June.

1. Odynerus sariensis sp. nov.

Black, a broad band on the sides of the apex of the clypeus and a mark on the base 

 of the mandibles pale yellow; the anterior tibiae and tarsi in front testaceous; the spurs 

 rufo-testaceous; wings almost hyaline, highly iridescent, the radial cellule smoky in front; 

 the nervures and stigma black. Ç.
