WiLDERMUTH (V. L.). The New Mexico Range Caterpillar and its 

 Control. — U. S. Dept. Agric. Washington, D.C., Bull. no. 443, 

 21st September 1916, 12 pp., 12 figs. 



Hemileuca oliviae, Ckll. (New Mexico range caterpillar) is a serious 

 pest in Eastern and Southern New Mexico, as it attacks cultivated 

 crops as well as pasture land. At present it occurs chiefly in the north- 

 eastern and south-central portions of New Mexico, to a slight extent in 

 the adjoining parts of Texas, and was found in 1915 in small colonies 

 in southern New Mexico. Though the moths have been found outside 

 these limits, no caterpillars have been recorded elsewhere. A total 

 abandonment of these areas of New Mexico was threatened ov^ang to 

 the ravages of this insect, the economic importance of which is con- 

 siderable. The character of the injury is two-fold : first, by the 

 eating down of the grass and consequent destruction of the pasturage, 

 or in the case of cultivated crops, by devouring the leaves and some- 

 times the tender shoots ; and secondly, by the scattering of poisonous 

 spines over the ground by the caterpillars. f
