THE CANADIAN ENTOMOLOGIST 137 



On June 13, 1902, two larva? in the last instar collected at Aweme, 

 Man., were received at Ottawa. On the earth in the breeding jar 

 small pieces of bark and rotten wood were placed to see if the 

 larvae w'ould use such for pupation. Both specimens, however, 

 •entered the earth (June 14) and there transformed to pupcB (June 

 17). 



Habits of the Adult. 



The moth of Leucohrephos brephoides is a sun-loving creature, 

 being most active between the hours of 11 a.m and 3 p.m. It is 

 among the earliest of the moths to appear in spring. It has been 

 collected in Manitoba as early as March 18 and as late as May 11. 

 The time of emergence from o^'er-wintering pup?e is, of course, 

 largely governed by the prevailing climatic conditions. It is not 

 unusual to see the moths on the wing before the snow has all 

 disappeared. Oviposition habits have already been referred to. 

 •Owing to a quick, jerky, flight and habit of darting upwards at 

 the least sign of alarm, and also in view of the fact that the moth 

 has a marked colour resemblance to the surrounding landscape, 

 it is difficult to follow with the eye and individuals, therefore, 

 are extremely hard to catch. Its remarkably acute eyesight and 

 habit of flight undoubtedly account for its rarity in collections. 



Experiments with the usual "sugar" mixtures, in daytime 

 instead of at night, indicated that such are of no \'alue to attract 

 the moths. They have, however, on several occasions been in- 

 duced to alight upon putrid flesh, which had been placed on the 

 grouTid. The moths also seek moisture and are often found fre- 

 quenting muddy roadways in the vicinity of aspen woods.
