“arrow heads” pointing towards the basal area. The incon- 
stancy of these local races, and Fruhstorfer’s mania for creating 
therefrom sub-species, is carefully discussed and dealt with by 
Mr. Wheeler in the article on ZL. arion in Tutt’s ‘ British Butter- 
flies,’ vol. iv, where also ligurica, Wagner, is diagnosed at length. 
Mr. Morris writes: ‘‘I have had no luck at all with this beauty 
at present, common though it is. Iamalways too late, and find 
only worn ones, or a small second brood and rare.” This sug- 
gestion of a (partial ?) second emergence is very interesting when 
it is remembered that the writer does not return to Cannes 
before the beginning of October. 
[L. euphemus.—L. arcas.—There is an element of humour in 
Milliere’s observations on these species (‘Cat.des Alpes Maritimes,’ 
2° Suppl., p. 4). A single euphemus, he says, was met with in 
August in a moist meadow bordering the Upper Var. Immediately 
underneath this record follows L. arcas—‘‘ August. Valley of 
Vésubie, where it flies in company with euphemus.”’ What is to 
be inferred from the conjunction? I can only conclude that the 
single supposed euphemus was well attended by its congener. At 
all events, both records require, and have never to my knowledge 
received, confirmation. |

LEPIDOPTERA FROM THE ARGENTINE AND FROM 
CANADA. 
By F. G. Wuirtie. 
In April, 1918, during a short visit to the Argentine, I was 
able to devote a little of my time to collecting Lepidoptera. At 
Lerviers, a few miles out of Buenos Ayres, on the Buenos Ayres 
Western line I found Colias pyrrhothea, Hiibn., common, and 
without any difficulty got a long series, which, however, does not 
show a great amount of variation. The suffusion is a little more 
fiery in some males than in others. At Belgrano, Tigre, and 
Boulogne, suburbs of Buenos Ayres, I found a number of larve 
of a Saturnia ready to pupate. These duly spun up in a box and 
produced, after I had returned home, Automeris leucane, Gey. 
Diatrea saccharalis, Fab. (Larger Corn-stalk Borer), a very 
destructive insect, occurred on the trunk of an acacia; Hylephila 
phyleus, Druce, Ochyria argentina, Prout, Cidaria impromissata, 
Walker, Callicista thius, Hubner, and an Arctiid larva which, after 
my return home, produced Hepantheria indecisa, Walker. In 
Buenos Ayres itself I got, attached to a fence enclosing a small 
patch of cruciferous weeds, a few pups of T'atochila autodice and
