the name Axomalostoma alloneura (pp. 15-20, pl. i. figs. 6A, 6B), 
worked out with that care for which he is so well known, the 
examples having been taken at Auckland by Frauenfeld. 
Brauer evidently had suspicions that Azomalostoma might be 
identical with P#z/anzsus, as is indicated at p. 16, and entered a 
protest against the adoption of Walker’s name in case the insects 
should prove the same. It is not my intention here to enter into 
a discussion on the application of the rule of priority ; suffice it 
to say that I agree with Brauer on principle, but sometimes 
doubt the practicability of his suggestions. He placed the insect 
in the family Rhyacophilidz, in which he was followed by me in 
the Journ: ‘Litin: Soc., vol. x.;p.'2T4. 
Now that we know the habits of the insect, it is clear that it 
cannot remain either amongst the Hydropsychidee or the Rhya- 
cophilide. In both these families the larve construct perma- 
nently fixed cases, not moveable tubes. The anomalous structure 
of the palpi, and also the neuration, would suggest the Sericosto- 
matidee as a position ; but in this family the maxillary palpi of 
the male are not only differently formed to those of the female, 
but have also fewer joints. In P£Azlanisus the joints are five in 
both sexes ; therefore I see no alternative other than to consider 
it an anomalous form of the family Leptoceride, to which the 
structure of the larvais not opposed. Perhaps the point on which 
itis most divergent from any other described species of this 
family is the structure of the apex of the abdomen in the female, 
which is produced into a very long, straight, pointed, horny 
ovipositor (as in many Hydropsychide and Rhyacophilide, but 
more pronounced); in what way this structure may perhaps bein 
correlation with the presumably constant marine habitat remains 
to be seen. 
The importance of Prof. Hutton’s discovery rendered it desir- 
able that a detailed account should be given as far as the materials 
would permit. Now that the connection of this marine larva 
with Philanisus is proved, I hope he, or some other entomologist 
in New Zealand, may be able to give us fuller details ; examples 
of the larvee and pupe preserved in alcohol are also desirable. 
POSTSCRIPT. 
In the same package with the materials for the marine Caddis- 
fly Prof. Hutton forwarded specimens illustrating the economy 
of two other species of New Zealand Trichoptera, from the Weka 
Pass, Canterbury. 
(i) Helicopsyche-—Numerous cases regularly formed, constructed 
of fine sand, 3%-4 millim. in diameter by 134-2 millim. high, 
with nearly three complete whorls. Some are empty; others 
contain larva and pupxe. Accompanying them were two female 
pupee emerged from the cases, and ready for the final metamor- 
phosis. So far as can be judged, the perfect insect should be 
congeneric with the species that have been reared in Europe and
