THE LESSER CHESTNl T WEEVIL. (BaJaitiinis rectus Say.). The lesser chestnut weevil (fig. 5) has the scape of the antenna longer than in the preceding species and the first joint longer than the second.'^ The average length of the body is about one- fourth of an inch, but the size varies, as in all of these insects. The distribution of this species extends from Canada and Massachusetts to North Carolina, Tennessee, and Ohio, and ])rol)ably farther west- Avard. The writer has seen sets of specimens labeled "; Although in some localities the larger species is much more in evidence, taken all in all. the lesser weevil is the more com- mon and is probably even more widely disseminated. The egg has not come under observation, but is undoubtedly very similar to that of the preceding, being proportionately smaller, which is true of the remaining stages. The larva is only a third of an inch long and its length is about three times its width. The body is milk-white and the head light bi-ownish yellow, while the has a short lateral branch each side. The pupa differs from that of the larger species by size and by characters shown in figure G, Avhich illustrates the male. "In the larger species the first joint (otnittlng. the scape) Is shorter than the second. In
