I can get a look at under a sufficiently high power, are stiff and short, 
but tapering, not clubbed or swollen into processes. The tubercles 
are medium-sized brown cones. I cannot place them accurately 
without mounting. True legs short and strong in appearance. 
“ I cannot count the subsegments accurately, as the segmental 
incisions are somewhat obscure, and the dark mottlings, which tend to 
be arranged in a series of rings, probably suggest that subsegments 
are more numerous than is actually the case. At any rate, they are 
small and closely set; on one of the shorter abdominal segments, 
probably the 6th, I can count at least 20.” 
There is another little Oriental and Australian group with similar 
leg structure to Lycauycs, but differently shaped wings, which includes 
“ Addalia" impersonate, Walk. (? = accurataria, Christ.) and muscularia, 
Stdgr., of the Paltearctic Region, probably orthoscia, Meyr., and others 
from Australia, etc., and which will also need to be referred to Mr. 
Burrows. This I am sinking provisionally, and against my better 
judgment, to Pylarye. 
I have not much to add on the two-spurred genus Ptychopoda, 
which has not yet revealed any special homogeneity in the genitalia, 
and therefore offered a less promising field on which to invite the 
collaboration of the friend whose help I have been so constantly 
acknowledging this evening. I may point out that a good many 
species which have been referred to the genus— especially in South 
America — pretty certainly have nothing to do with it. A venational 
difference which Warren has often overlooked in his work is that many 
of them have the so-called “ double areole,” which never occurs in our 
European forms of the “ genus.” Coming nearer home, I conclude by 
putting one or two questions, again suggested by Mr. Burrows’ 
valuable work, and on which he may have a word or two to contribute, 
in connection with the fine exhibit of drawings which is before us. 
Is there a possibility of reviving, on the strength of his researches, the 
old claim of Ptychopoda mancuniata, Knaggs, to specific rank? And 
what is the relation of circellata, Guen., to normal straminata ? 
Personally, I believed both questions to be settled long ago in favour 
of absolute specific identity, but I desire always to keep an open mind 
for any new truth which may be brought within our reach. Finally, 
is it not possible to indicate some tentative grouping by the genitalia 
in Ptychopoda, which would bring into prominence such resemblances 
or divergences as have been noticed, and perhaps stimulate further 
research? I am aware that there is need for caution, and that nothing 
could be more undesirable than dogmatism on the subject, but I some¬ 
times think that some of our friends are in danger of undue extremes 
in caution, and that if a little more constructive work were essayed— 
even though only to be re-constructed later on — the net result of the 
proceedings might be a gain to science. For instance, if Mr. Buriows 
will tell us definitely — and to the lay mind it certainly appears that 
such is the case — that dimidiata, according to the genitalia, has to 
come out of the biseta ta - trigem in a ta group, with which its blotched 
outer area has associated it, he will make us anxious to see whether 
we can confirm or refute his statement from a study of the egg or 
larva, etc., and will thereby accelerate the work of classification in 
which so much yet remains to be done.
