Museum (Nat. Hist.), South Kensington. 
[Read February 28th, 1894.] 
A. rew days ago I received a letter from Mr. Herbert 
Clark, of Christchurch, New Zealand, enclosing two 
specimens of a very curious Homopterous insect, which I 
have succeeded in identifying with Dorydiwm westwoodi, 
Buchanan White. 
Mr. Clark writes, ‘‘ I found it on the rushes which grow 
in damp situations. In colour and shape it so much 
resembles a piece of dried rush that I have never been 
able to find a specimen except by switching the net 
amongst them. I think they are scarce and very local, as 
the specimens I have captured were taken in a space a 
few yards square, and I have never been able to collect 
them elsewhere. The place where they were found was in 
a plantation of Pinus insignis about a quarter of a mile 
from the sea, and a few chains from the river. The time 
of appearance is from the beginning of November to the 
end of the year.” 
The insect belongs to the family Jasside, and the 
references are as follows: 
Dorydium westwoodi. 
Buchanan White, Ent. M. Mag., xv., p. 215 (1879) ; 
Signoret, Ann. Soc. Hnt. France (5), x., p. 43, 
pl. 1, fig. 38, details (1880). 
One of the specimens received from Mr. Clark is a 
perfect insect (a male, I think), and the other a pupa, as 
may be seen by the rudimentary tegmina. The mature 
specimen measures 9 lines in length, and agrees with
