. Bulletin of the Department of Agriculture. Agriculture. 8 BULLETIN 539, U. S. DEPARTMENT OF AGRICULTURE. The soil in these plats was of a sandy nature. He further stated that a report was received from Boca Grande, Fla., that 2 of 18 acres of cowpeas had been destroyed by this pest. Mr. R. N. Wilson, of the Bureau of Entomology, who was instructed to investigate this infestation more fully, confirmed Mr. Dozier's statement, young plants being injured by the larvre boring into and upward in the stems, while in older plants the stems were girdled at or slightly below the ground. The result in both cases was that the injured plants wilted ana died, although it was noted that in exceptional cases the plants, being vigorous, overcame the injury. Mr. Wilson further submitted a letter which had been received from Mr. Joseph Crews, farm demonstrator at Arcadia, Fla., stating that the "worms" injured cowpeas, Japanese cane, corn, and chufa. Cowpeas wera damaged to some extent in the stiff black soil, but more serious damage was done in the sandy soil. This soil had all been well limed and heavily fertilized. Damage was done to Japanese cane planted in an old piece of land which was cleared years ago but had not been under cultivation for a number of years until the present. At least 90 per cent of the crop was damaged and the crop lost about 50 per cent in value. While the increasing number of records of damage by this insect in the last few years is due in part to the fact tiiat injury by it is more likely to be reported now than was the case years ago, it is also prob- able that the species is slowly modifying its habits to correspond with modern methods of agriculture and that, in the future, occasional outbreaks, perhaps more severe than any yet recorded, may be expected unless means are taken to check them in advance. THE EGG. The egg (fig. 2) is ovate, circular in cross section, mm. in length and mm. in diameter; greenish white
