Xiphydria. I therefore place it provisionally in Brachi- 
xiphus, the type of which is B. grandis, Phil., from Chili. 
B. flavipes, Phil., a second Chilian species, is, however, 
a true Derecyrta. I may add that D. bicolor, Westw., is 
certainly the male of B. grandis.

81. Monostegia antipoda, n. s. 
Exp. al. 5 1.; long. corp. 3 1. 
Deep black, legs more or less testaceous ; wings hya- 
line, with piceous nervures; an oblique shade below the 
7 eee ee 
stigma, most distinct towards the inner margin. 
New Zealand (Wakefield).—B. M. 
Described from two female examples. There is very 
little character about this species, the only true sawfly 
which has yet been met with in New Zealand; but I hope 
to figure it shortly. Mr. Smith mistook this for the 
European 7’. adumbrata, Klug; but the latter is a true 
Eriocampa according to the neuration. The neuration of 
M. antipoda is as follows :—Fore wings with two radial 
and four submarginal cells, the two recurrent nervures 
received by the second and third respectively; the first 
enters the second cell about the middle, and the second 
enters the third cell a little before the middle; the dividing 
nervule of the radial cells enters the third submarginal 
cell before the dividing nervule between the third and 
fourth ; lanceolate cell with oblique cross-nervule ; hind 
wings with one inner cell.
