DARTMOOR NOTES—ZYGAENA TRIFOLIT AND OTHER SPECIES. 31 
ance, viz., what I call the orobi form with all the spots separate, this 
being nearly always the smaller race, and the typical form with the two 
median spots confluent, which is generally a large form, though there 
is always a percentage of medium-sized specimens. 
Further than this in all large colonies it is usual to find a few of 
the form minotdes, Selys., z.e., with all the spots confluent; usually 
this is only present as a rare variety. Dr. Perkins’ exhibit is therefore 
of great interest, inasmuch as the two colonies, though near each other 
yet keep distinct, and the one shows such a marked tendency to develop 
the minoides variety. 
I should say that I have examined specimens from other collections 
but am unable to give the exact proportions of the forms, but they 
largely confirm my own observations. 
It may be of interest to record a few of my other captures, though 
none are new to the district.  Zephyrus (Bithys) quercus is always to 
be found, I could always go in July to one or two special ash trees I 
know of with the certainty of finding this species there, and it is a nice 
large race.  Plebeius aeyon (argus) is local, only occurring in certain 
places, but in one spot the females are unusually large and fine and are 
of two forms; among the ordinary brown ones are always to be found 
a fair number with the orange marginal bands well developed in both 
wings, whilst there is also a percentage shot with blue on both wings 
and especially on the secondaries. I took one fine female at the end 
of July of Celastrina argiolus, evidently one of the second brood. 
- I have taken the three large Argynnids in different parts of the 
Moor. In one spot, a sheltered valley, 1 have seen them all on the 
same morning, but paphia and adippe only affect, so far as my experi- 
goes, the sheltered wooded valleys, and not all of them, whilst aylaia 
is fairly widely spread. Aphantopus hyperantus is to be found in nearly 
all the bye-ways where the hedges are allowed to run their own free 
will; and though Pararye aegeria var. eyerides is abundant in the 
Devonshire lanes generally, yet on the Moor it is very much less in 
evidence, and whilst it is well out in May and early June in the former 
localities, in the latter it is later and occurs all through July but not 
in exposed situations. I have already said that Callimorpha dominula 
occurs alongside Zyyaena trifolit in certain localities, but only I believe 
in very sheltered ones, at least I have only found it in one or two such 
places. Among the other Heterocera perhaps the most interesting 
that I took last summer are Cybosia mesomella and Bomolocha fontis 
(crassalis), and also some nice strongly-marked specimens of Crambus 
geniculeus. 
This little record is, of course, very meagre and does not represent 
all the specimens that I took or noticed, but my visits to Devon and to 
Dartmoor are not generally entomological, for except when my cousin 
is with me and we take big walks, and these are not infrequent, my 
time is generally spent, apart from drives with my wife, in quest of 
something special—as trifolii—or in solitary wanderings over the hills 
and avoiding the bogs, enjoying the scenery and watching the birds 
and other little beasties that come across my path; too often I have 
not even taken a net with me, so that in this way I have, I believe, 
missed being able to make one or two records when I have thought I 
have seen certain species that are not supposed to occur in the district.
