Lepidoptera 47 1 
Larv^ Collected during the Expedition. 
Various members of the Southern Party of the Canadian Arctic Expedition 
collected lepidopterous larvae under stones, etc., and these were placed in alcohol. 
In most instances the specimens were immature, and without a knowledge of 
the adults it is not possible to make a report of any value on them. Such 
larvae are of the families Nymphalidae, Noctuidse, as well as others of the 
Microfrenatae. 
In 1915 and also in 1916, Mr. Johansen found at Bernard harbour. North- 
west Territories, specimens of a small lepidopterous larva feeding commonly 
in the roots of Pedicularis lanata. The first larva was found on July 4, 1915. 
Under this date Mr. Johansen's note reads: '' Larva 10 mm. long, flesh-coloured, 
with head, neck plate and thoracic feet brown, found in the root of the common 
red-flowered Pedicularis. The larva had made a tunnel 15 mm. long, down 
the middle of the root." Other larvae of similar size were collected on July 16. 
On July 18, a further examination of plants showed that the larva did not 
confine its burrows to the roots but that it also tunnelled the stem feeding 
upon the pith. As a rule only one occurred in a plant. The larva was further 
met with both in the roots and the stems of Pedicularis on the island forming 
the north side of the harbour, at Bernard harbour, on June 10, 1916. Unfor- 
tunately no adults were reared from larvae kept under observation. (Breeding 
record 71.)
