larvje were found on alder, birch, bird cherry and willow, but more often the 

 former ; Papilio brevicauda, difficult to catch on account of its flying about 

 Epilobium flowers, growing among tangled debris of forest fires ; many larvae 

 of this species were, however, found in August on wild parsnip and about 30 

 pupse are now on hand ; Brenthis myrina, Phyciodes tharos, Aglais milberti, 

 and other species were remarkable by the form or color exhibited ; CEneis 

 jutta was found only in the bogs and was hard to catch, as the treacherous 

 surface made running impossible ; also this species would light on lichen- 

 covered trees where its protective coloring made it nearly invisible. The 

 Newfoundland form of this species varies greatly from that found in British 

 Columbia, and seems worthy of a varietal name. Rusticus aster, a species 

 peculiar to Newfoundland, and sufficiently rare to be missing in the Museum 

 collections of New York, Brooklyn and Washington, was represented by (^ 

 caught July 15 and 5 August 10. 



Agriades aquilo, a little blue butterfly, confined to subarctic regions, was 

 found on Caribou Island, Battle Harbor, Labrador, clinging to lichen-covered 

 rocks, taking to flight suddenly upon the appearance of sunshine, often flat- 

 tened against the rocks by the wind, and leading apparently a precarious life 

 for so delicate an insect. 24 diurnals in all were taken and indicate that the 

 fauna is principally an extension from the northern temperate zone, in some 

 instances from British Columbia right across the continent, with a tendency 

 towards a darkening of the colors probably influenced by the moist climate. 

 After commenting upon the Sphingidae, Noctuidje, Sesiidte and Geometridae, 

 in which the same relationship and tendency .to change in coloration were 

 noted, and pointing out that Geometers could be found in bad weather cling- 

 ing to the sheltered side of overhanging rocks, on tree trunks, etc., by careful 

 inspection ; that the boggy tops of the mountains yielded mainly the same 

 insects as the lowland bogs ; and the difficulties in moving about freely in 

 search of Lepidoptera caused by the absence of roads, the impenetrable 

 thickets, the nature of the bogs and the swarms of black flies. 



Mr. Engelhardt closed by stating that the Labrador collection was too 

 small to warrant drawing any conclusions, especially in the absence of a 

 representation of the fauna of northern Newfoundland; and that while 150 

 species of Newfoundland Lepidoptera were shown, he believed it would be 

 possible to collect 500 to 600 species by working from June 15 to October i, 

 in the varied environments afforded by the Island. 



Mr. Grossbeck exhibited the Lepidoptera collected by Mr. Leng on the 

 same journey, and called attention especially to three Geometers, Hydriomena 

 5-fasciata and grandis and Petrophora pontiaria, as common in the north- 

 west but not previously known to occur east of Alberta ; also a Carsia suft'used 

 with pale carmine apparently new unless identical with labradorensis. He 

 also pointed out the small size of Nephelodes minians collected at Spruce 

 Brook, and the dark hind wings of the HeUot>hila hiteopallens, a character 

 which chiefly distinguishes the western species oxygale. Trichodecia albo- 

 vittata was another abnormal form, the oblique white band being almost twice 

 as broad as in normal albovittata and two anterior lines strongly marked ; and
