of a lot of larv^ also will make their cases after second moult, others after 

 third and in the following spring. Some, but not all, of those which hiber- 

 nated after second moult, will pass three more moults. There would seem 

 no reason why some larvje of the first of the three Virginia broods should 

 not make cases, as some of the second (in mid-summer) do. And cer- 

 tainly we could not say positively that they do not ; nor do I see how one 

 could say positively that some of the first New England brood do not 

 make cases. The evidence against it is negative only. I have found 

 that caterpillars and butterflies are apt to do just what we would think 

 they could not. I never knew of a larva hibernating after first moult, as 

 it is stated that they " not at all infrequently" do, on page 275 ; nor do I 

 think the small larva?, after that moult, would have the physical ability to 

 cut out and weave together a case. 



A RAINY DAY ON THE MOUNTAINS. 



BY DAVID BRUCE, BROCKPORT, N. Y. 



There is a tradition extant in Denver that tlie sun shines in Colorado 

 nearly every day. This last summer was a woeful exception, however, 

 for, from the middle of April until the end of June, the weather would 

 have been thought respectable only in Labrador, but the unusual wet and 

 cold spring, although it retarded the insects, gave such an impetus to the 

 growth of flowers and herbage on the mountain sides and tops, that, when 

 the hot weather set in, all species of diurnals appeared to be unusually 

 abundant, and every kind seemed to be flying at one time. I had col- 

 lected for some time with indifferent success during this wet season in the 

 foothills and lower canons, and I made up my mind, despite the weather, 

 to try the higher ranges. So I climbed above timber line one showery 

 afternoon the beginning of June, and spent the night in the same shanty 

 I had occupied on my visit in 1887 ; the proprietors, two honest miners, 

 welcomed me heartily. The next morning was gloomy, cold mists rolled 

 up from the valley and white clouds collected round the peaks, but I 

 donned a pair of miner's overalls and went out determined to do some- 

 thing. In a drizzle that seemed as much snow as rain, I climbed the 

 sloping sides of Mount Bullion, which was covered more thickly with
