shallow furrow on the basal two-thirds in the middle. Scu- 

 tellums finely punctured, and thickly covered with long white 

 hair. Metathoracic area closely, irregularly striated, its apex 

 smooth and shining ; the apex has an oblique slope, is finely 

 punctured, is widely furrowed in the middle, and is thickly 

 covered with long white hair. Propleurae shining, the middle 

 furrow minutely striated; mesopleurae alutaceous, thickly 

 covered with long white hair ; in the middle, at the base, is a 

 shallow oblique furrow, the part above it being raised ; the 

 metapleurae are finely rugose. Legs thickly covered with 

 white hair ; all the knees, the front tibiae (except behind), the 

 greater part of the anterior tarsi, and the four posterior tarsi 

 broadly at the base bright-yellow ; the spurs yellow. Wings 

 clear hyaline ; the stigma fuscous, the nervures darker ; the 

 first recurrent nervure is almost interstitial, being received 

 immediately in front of the transverse cubital ; the second 

 recurrent nervure is received more distinctly in front of the 

 third transverse cubital. Abdomen shining, thickly covered 

 with a short white pubescence ; aciculated ; the depression on 

 the basal segment is large, deep, triangular ; the apical ventral 

 segments have the apices testaceous ; the penultimate segment 

 is slightly normally incised ; the others transverse. The pu- 

 bescence on the abdominal segments does not form bands; 

 the second and third are distinctly depressed at the base ; the 

 last is transverse at the apex ; the lateral furrows are oblique, 

 and reach near to the base. 



The eyes distinctly converge below, and have, on the inner 

 side above, a distinct semicircular curve ; behind them the 

 head is obliquely narrowed. The apex of the median segment 

 has a distinct margin laterally, almost keeled. Mesosternum 

 alutaceous, broadly but not deeply furrowed down the middle. 

 The pronotum in the middle behind is depressed, and has 

 there a short, distinct, longitudinal furrow ; its base has a 

 harrow but distinct margin. 



I may take this opportunity of pointing out an important 

 change in nomenclature. In " Notes on a Collection of 

 Hymcnoptera from Greymouth, New Zealand, with Descrip- 

 tions of New Species,""^' I described a new genus of IcJmeu- 

 monidce, founded on the species described by Mr. W. F. Kirby f 

 under the name of Bhyssa semvpunctata, which I called Xeno- 

 pimpla. When doing so I had, however, unfortunately over- 

 looked the fact that the genus had been already described by 

 Dr. Kriechbaumer in " Eniomologische Nachrichten," xv., 

 p. 309, 1889, as Lissopimpla. It is grounded on three Aus-
