precipitously to the height of 2000 feet or more. It was along 

 this narrow strip or belt of land bordering the sea that nearly all 

 animal life was found. The soil was fairly fertile, though frozen 

 below the depth of a few inches. Along this strip many flower- 

 ing plants were growing. Here we caught many of our larger 

 insects, but where the vegetation became scarce along the base 

 of the mountain where the great mass of boulders lay which had 

 become detached from the mountain side, the micros were most 

 abundant. They were extremely hard to catch, and being nearly 

 of the same color as the lichen-covered rocks, were more easily 

 overlooked. When detected they would run rapidly and hide 

 under some projecting leaf or rock. They flew with a quick 

 jerky flight for a short distance and generally alighted on the 

 rocks or on the lich'ens with which they were covered, and seldom 

 alighted on the herbage. 



' ' Diligent search failed to discover any cocoons. Several minute 

 larvae about one-fourth in. long, of a pea-green color were found 

 crawling along the side of the boulder. I was unable to mid 

 the food-plant, but attempted to raise them offering them both 

 moss and lichen, but they refused to eat and died. Another larva 

 was found on the stem of some species of Campanula. It was 

 green inclining to olive in color on the forward part, and was 

 about three-eights of an inch long. I attempted to raise this 

 larva also, but it refused to eat, and therefore died. I believe, 

 however, that it may have been the larva of one of the micros, 

 though of course I do not know. 



" Willow and birch are the only trees found in Greenland, and 

 in the northern part, at least, they never exceed four or live in- 

 ches in height. I am inclined to think that these little trees are 

 the food-plants of a number of species, notwithstanding the fact 

 I was unsuccessful in locating the larvae." 



The information given by Mr. Mengel in his letter to me, ex- 

 tracts of which are given above, is of great interest, and gives us 

 a better idea of the conditions under which these insects lived 

 than we might otherwise obtain. 



rnfortunately, all the specimens sent to me are marked ' ' Green- 

 land," but Prof. Skinner, who sent them, stated that they were 

 taken at McCprmick Bay. 



One of the species sent is a small pale green Geometer in very 

 .;- condition, but strongly resembles Ncmoria. There were
