also four examples of Laodatna fusca Haw., one male and three 

 females. This species has a wide distribution occurring over 

 northern and central Europe, Japan, North America, Iceland and 

 Greenland. 



The larva is supposed to feed on Betula and Calluna, and has 

 been bred from the egg on Vacciyiium myriillus, and also on 

 Salix caprea. It is therefore very probable that the larvae of 

 this species fed on the dwarf birch or willow as Mr. Mengel con- 

 jectured. 



It is not probable that the larvae found by Mr. Mengel belonged 

 to this species since the imagos were on the wing during the 

 seven days he was at McCormick Bay, and at this time they laid 

 their eggs, which are known to hatch in about ten days, and they 

 are supposed to hibernate during the Winter as half-grown 

 caterpillars. 



There were in the collection thirty-two examples of Pyrajcsta 

 iorvalis Moesch. This species was first described by Moeschler 

 in the Wiener Entom. Monatsch., Band vii, p. 198, pi. v, fig. 16 

 (1864), from Labrador, and Staudinger also gives the Pyranees 

 as its habitat. The early stages and food-plant are unknown. 



The collection also contained ten examples of a new species 

 which I have named for Mr. Mengel, the entomologist of the 

 expedition, — 



Sericoris mengelana n. sp. — Expanse of wings 20 mm. Head and an- 

 tennae black; palpi black, whitish at the base, and with a whitish spot on 

 the outside of the second joint. Thorax black, with a few scattered white 

 scales almost forming a band across the thorax just in front of the small 

 tuft. Fore wings black, with a white spot on the basal third of the costa 

 extending down to the median vein, and on the costa in the middle of 

 this spot there is a small black spot with another below it. On either side 

 is an oblique black hair line through the white spot, below which are a 

 few scattered white scales. From the outer fourth of the costa a white 

 band extends to the anal angle. This band sends out a prolongation on 

 the costa and one into the cell, and it also has two black spots on the 

 costa, the outer one of which is elongated. Two minute white spots rest 

 on the deep black ground of the middle of the costa, and the basal part 

 of the costa has a few sprinkles of white. The fringe is black at the apex, 

 but black and white mixed elsewhere. Hind wings and abdomen above 

 dark ashy gray. Underside of the abdomen and wings ashy gray, with 

 the markings of the upperside of the wings indicated. Legs dark brown, 

 annulate with whitish. 



Described from ten examples in poor condition.
