summer in Washington, D. C. The insect has a wide range, 
being known to occur in the West Indies and Central America. 
Genus PHLYCIVENODES Guenee 
This is a genus well represented in both hemispheres. There 
are over thirty species found in the United States. 
(1) Phlyctaenodes triumphalis Grote, PlateXLVIII, Fig. 5, $ . 
This species, which is found in the vicinity of San Luis Obispo, 
California, was described by Grote in the “Canadian Entomolo¬ 
gist,” Vol. XXXIV, p. 295. It does not appear in Dyar’s List. 
(2) Phlyctaenodes sticticalis Linnaeus. (The Sugar-beet 
Moth.) 
Syn . fuscalis Hiibner; tetragonalis Haworth; sordida Butler. 
The moth, of which we give an enlarged representation in Fig. 
218, has becmee in recent years the object of attention in 
those portions of the 
West in which the 
cultivation of the 
sugar-beet has be¬ 
come an industry of 
magnitude. It has 
done considerable 
damage to the crop 
in Nebraska. There 
are two and perhaps 
three broods pro¬ 
duced in a year. The 
insect multiplies with 
great rapidity, and 
large areas planted 
with the beet have 
been defoliated by the 
caterpillars in comparatively a short time. The larvae hibernate 
in cases woven of silk to which particles of earth are adherent, 
and which are formed at a small depth under the surface of the 
soil. By harrowing the ground it has been ascertained that many 
of the cases are thrown up, and are emptied of the larvae by the 
meadow-larks and other insectivorous birds, or are killed by the 
frosts of winter. Many of them, however, escape such treat-
