CHEONOLOGY, 1879: WYOMING.

summit by the Weather Signal observers on Pike's Peak. No speci- 
mens were observed among the foot-hills at Mauitou Springs. 
A few small swarms flew over from the mountains to the plains, as 
will be seen by the following data communicated to us by Mr. J. S. Stan- 
ger, editor of the Colorado Farmer. The Locust appeared about the 15th 
of July in small flights on the Cache a la Poudre and Saint Vrain Bivers? 
in Laramie and Boulder Counties. July 23 a flight passed over Denver 
and alighted at Littleton, on the Platte Biver, but did not remain there 
an entire day, flying southward. They came from the Bear Biver Val- 
ley. It will be remembered that locusts were seen in abundance in 
White and Bear Biver Valleys early in September, 1878. The flights 
this year were evidently the progeny of these locusts. 
The only other instance we could learn of was from Mr. J. B. Piper, 
who sent us a long-winged genuine male C. spretus, with the following 
note, dated August 1 : 
Inclosed find a specimen picked up by me at dark this evening at West Las Animas, 
Bent County, Colo. They were in moderate numbers and flying north. 
From this it will be seen that there were a less number of locusts in 
Colorado this year than even in 1878. The summer in Colorado was 
unusually dry, the rainfall of June, at Denver, being .32 inch. In May 
there was a slight excess of rain, as the United States Weather Signal 
observer informed us, and the spring was not unusually dry. The sum- 
mer, however, was regarded as the driest since 1863, as it was through- 
out the Bocky Mountains. 
No need to be alarmed at the report about locusts hatching. Eiley says a few 
hatch out every year in some places in Colorado. — [Colorado Farmer, June 12,1879. 
THE LOCUST IN WYOMING IN 1879. 
In this Territory also locusts were still less frequent than in 1878. 
A few were seen the middle of July, at a height of 150 to 200 feet in 
the air, at Bock Creek Station, we were told by a person at this point. 
None were seen this season, so far as we could learn, between Sidney,, 
Nebr., and the Black Hills. 
The following data have been received since our return : 
Lieut. C. A. H. McCauley, U. S. A., writes from Fort Steele, on the 
North Platte, July 3, 1879 : 
A cloud of Orthoptera, as per sample, has been all day long passing through and 
over the post ; numbers great, flight low, direction of arrival from the south and 
southwest chiefly ; a strong, high wind from that direction prevailing all day. Tem- 
perature high, about 90 c F. Alighting on ground ; flights short when disturbed. 
The same correspondent, in a letter dated Fort Steele, Wyo., August 
12, 1879, continues as follows : 
It will probably be of interest to add that my survey extended to the southwest 
some 50 miles, during which I observed the extent of the Orthoptera observed here be- 
fore starting out. The route was up the North Platte and tributaries in the east, 
farthest point a locality on Brush Creek; situation, long. 106° 30' W., lat. 41° 23' N., 
both approximate, and altitude some 1,200 feet above this (6,850 feet above the sea)^
