Baloninus confuf^or Ham. has bt'en reared from the acorns of bear or scrub oak {Quercus nana ilicifolia), but it probably lives on the fruit of other Fig. 10.—Pecan nuts showing exit hole of pecan weevil larv;e, one-third enhirged (original). An interesting' faet Avas brouoht out in the rearing of the last- mentioned species which has a bearing on the liabits of the genus. A single individual was reared from a large apple oak on a species of golden rod {SolidcKjo Heviorallfi)^ due to the larva of a two-winged fly, Acmia solldagmis Fitch (see Can. Entom. Vol. XXV, p. 310), showing the possibility of the different species developing on other than their normal food plants. In this case, as Hamilton remarks, oviposition on the gall was probably a mistake on the part of the parent beetle. Three of the larva? were observed. It might be impossible for species with short snouts like the hazelnut weevil to oviposit in chestnuts on account of the thicker husk and longer spines, but, on the other hand, it might be possible for some other species to depredate on hazelnut in the event of absence of the normal nost plant. nBalaninus victoriensis n. sp. (fig. 9).—With a view to lessening the confusion which has existed with reference to the name of this species, which is generally known in collections as uniformii^ Lee. or obtusus Blanch., the writer presents a brief analysis which, together with the illustration, will
