56 FIFTH ANNUAL EKPORT 



EGG OF THE BROAD-NECKED PRIONUS — P^-fo/ms laticollis 



Druiy., 



The eggs of this species (Rep. 2, Fig. 61) are elongate-oval, 0.15 inch 

 long, and three times as long as wide. They are bright yellow, opaque, 

 faintly granulated, (or rather impressed with abbreviated strias), and 

 fastened by a glutinous substance to stumps and old trees, about 

 half an inch below the surface of the ground. The process of ovi- 

 position has been well described, {Rural New Yorker^ July 20th, 

 1871), and I have obtained upward of 140, eggs from a single female 

 in one night. The eggs of the other species of the genus are doubt- 

 less similar. 



EGGS OF AMERICAN TENT-CATERPILLAR— Clhiocampa Ame- 

 ricana Harr. 



The figure of the egg-belt of this moth, which I have already 

 [Fig. 29.] given, (3d Rep. Fig. 50, c), is incorrect, in that it indicates the 

 eggs to be bare, whereas, as described in the text, they are 

 thickly covered with a glue-like varnish, which almost con- 

 ceals them. That figure was not made from nature, and I 

 was misled, at the time, by an incorrect figure given by 

 Emmons in his ''Insects of New York." The annexed figure 

 (29) will give a far more correct view of the unhatched mass. 

 There is some variation in the amount of glutinous matter 

 covering the eggs, which are, at times, quite visible, at 

 others not ; and this diilerence may be connected with the 

 difference of climate. 



COUNTERWORKING THE TOBACCO WORM. 



Mr. E. M. White, of West Fork, Reynolds county, sends me the 

 following account of his method of counterworking the Tobacco or 

 Potato worms, (1st Rep. p. 95): 



" In every tenth hill on the outside rows of my field, I sow the 

 seed of Jamestown Weed, {Datura stramonium), instead of setting 

 tobacco plants. As the Daturas grow up, I pnll out all but two to 

 each hill, and when these are in bloom, I go around every evening, 

 and, after destroying all but two flowers, pour into these a few drops
