two thousand feet, the small village nestles at the foot of 

 heavily wooded parallel ridges, which attain an altitude of from 

 thirty-two hundred to four thousand feet in the immediate vi- 

 cinity. The rich mountain-valley pastures and deciduous forests 

 were evidently teeming with insect life and, having occupied a 

 small white cottage on the hillside on July 3, 1916, preparations 

 were made for extensive collection of Orthoptera. 



"A broad veranda, facing westward over the valley, had its 

 w r all and ceiling painted white and the three electric lights 

 were seen to throw their radiance some distance through and 

 over the trees below. Having changed the lights for those of 

 one hundred candle power, the place was found to be ideal for 

 collecting not only the few night-flying Orthoptera. but also 

 the abundant Heterocera. 



"In order to secure the moths without rubbing, two large 

 cyanide jars were used ; one in which the captures were made, 

 these being dumped into the other jar as soon as movement had 

 ceased. This was found to be a very important detail in the 

 proper preservation of this delicate material. 



"The appearance of the moths was very irregular, some 

 nights being inexplicably bad, many good, while on occasional 

 evenings, when no apparent difference in climatic conditions 

 was noted, an extraordinary number of species as well as 

 individuals would make their appearance. Individuals could 

 be taken from twilight throughout the night, the largest number 

 being usually secured between eight and ten. Scarcely any 

 work, however, was done after midnight, and so we have few 

 data for the hours before dawn, during which, we have reason 

 to believe, moths sometimes appear about lights in some regions 

 in remarkable abundance. 



"Sultry nights are well known to be very favorable, but 

 during this work almost every warmer afternoon was followed 

 by a thunder storm which, at this altitude, almost invariably 

 lowered the temperature to a point where further collecting 

 proved to be of little avail. It was interesting to note, howevrr, 

 that long after the high winds and rain had commenced, speci- 

 mens of all sizes would often continue to come in. 



"The study of first appearance and duration of the various
