apical area pale flesh-coloured, containing two small black costal spots 
from which arise two narrow, outwardly oblique, short bars of yellowish- 
brown ; a series of four or five small whitish spots along dorsum, the 
largest close to base of wing, this with its fellow on the opposite wing 
anastomasing with the thoracic spot when the wings are folded in the rest¬ 
ing position ; blue cilial line ; cilia dark grey, intermingled with a few light 
brown. Hind-wings light brown, densely irrorated with darker brown 
scales; dark grey-brown cilial line ; cilia light grey-brown. 
Type in the author’s private collection. 
The life-history of this elegant little moth will shortly be published. 
The colouring is a most perfect example of protective marking. Food- 
plant, Poly podium serpens , in the leaves of which the larva mines. 
Habitat: Wellington, Wanganui, in October and November. 
NOTE ON THE PORT WAIKATO MESOZOIC FLORA. 
By J. A. Bartrum, Auckland University College. 
A few years ago I sent a collection of fossil plants from the Port 
Waikato Mesozoic beds to the late Dr. E. A. Newell Arber, but his death 
occurred before he was able to examine them. The specimens were then 
forwarded by Mrs. Arber to Professor A. C. Seward, who has been so good 
as to report upon them in a recent letter. 
Besides certain other species reported by Arber,* Professor Seward 
identifies the following plants not previously known from Port Waikato :— 
(1.) Araucarites cutchensis Feist. 
(2.) Coniopteris hymenophylloides (Brong.). 
(3.) ? Stachyotaxus cf. S. elegans Nath. 
(4.) Elatocladus plana (Feist.). (May be identical with Elatocladus 
sp. of Arber, pi. xiii, fig. 9.) 
Amongst the plants forwarded was a specimen labelled in Professor 
A. P. W. Thomas’s handwriting as Asplenium palaeopteris (Ung.). This 
is regarded by Professor Seward as probably the same as Coniopteris 
hymenophylloides (Brong.). 
With the exception of the “ Asplenium ,” the fossils were all collected 
by Rev. Brother Fergus, of Sacred Heart College, and myself, from plant- 
beds at the coast near the mouth of Huriwai Stream, about five miles south 
of Port Waikato. 
Professor Seward remarks in his letter to me : •“ Perhaps the most 
interesting is Elatocladus plana (Feist.), which may be, I think, the same as 
the specimen named by Arber Elatocladus sp. ; I feel practically certain 
that this conifer is the same as that described by Feistmantel from Jurassic 
rocks of India.” In referring to the “ Asplenium palaeopteris (Ung.) ” he 
says: “ Some years ago, in describing certain English fossil plants, I 
suggested that Unger’s specie? might be identical with a Wealden species 
from England, but I had, of course, only his figure to go by.”f
