Packard, A. S. The Rocky Mountain Locust in New Mexico. Am. 
Nat. xiii. p. 586. 
Recent records on the invasion of New Mexico by Caloptenus spretus, 
from Southern Colorado. The Pueblo Indians have been in the habit of 
storing grain two or three years in advance, in anticipation of either 
drought or attacks of locusts. 
Posada-Arango, a. Note sur le Criquet voyageur de la Colombie. Le 
Naturaliste, i. pp. 4 & 5. 
Concerns an insect found in the States of Colombia, at the mouth of 
the river Patia, and very destructive there. Full description and account 
of habits given. 
Riley, C. V. The Philosophy of the Movements of the Rocky Moun- 
tain Locust. P. Am. Ass. 1878 (1879), pp. 271-277, map. 
The author divides the district infested by Caloptenus spretus into • 
(1) the permanent region, (2) the sub-permanent region, (3) the tem- 
porary region. The principal causes of migration are hunger, the pro- 
creative instinct, increase pf enemies, and instinctive impulse. The map 
illustrates the regions, &c., as indicated. 
Brunner von Wattenwyl, SB. z.-b. Wien, xxix. pp. 26 & 27, calls atten- 
tion to an unobserved structure in the hinder femora of A crydiidoi. In the 
grooves of the under side, about one-fourth from the base, is a sort of 
hollow tubercle, filled in by a whitish cushion. It is found equally in 
those genera that do not stridulate, and so cannot be connected with the 
production of sound, but it is absent in the few genera that do not leap, 
and hence is probably connected with the springing motion. An abstract 
is given by the author in Le Naturaliste, i. p. 94. 
Ctyphippus ccerulescens, L., and miniatus^ Pallas. Krauss, Verh. z.-b. 
Wien, xxix. p. 61, maintains that these are distinct species, and that the 
latter is not a red variety of the former, as is generally supposed.
