Balnninns tictori€nsl>i Chttn. n. sp."iaalsoan acorn weevil, having' )jeen collected in 

 great numbers on oak by various collectors. 



Bnhmbms obtu><us Blanch, has been reared from hazelnuts only (Hamilton, Can. 

 Ent., vol. XXII, p. 6). In 1891 hazelnuts were reported badly injured by this 

 species in Iowa (Alda M. Sharp, Bui. 17, Iowa Agl. Ex. Sta., p. 450). 



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 oaks.

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 more clearly define its identity: 



Body black or nearly so, covered with dense gray scale-like pubescence; elytra 

 variously mottled with brown, slightly elevated, pubescent spots. Rostrum 9 four- 

 fifths as long as body ( including head ) , moderately, nearly uniformly arcuate. Anten- 

 nal joints as figured, length a little shorter. Length, 7""°.; width, 3.5°"°. Habitat: 

 Victoria and elsewhere in Texas. Related to uniformis Lee. from California, which 

 is described as "densissime fulvo-puhescens, concolor," etc. The latter is smaller. 

 B. ohtasus is much more robust and has a much shorter rostrum in 9 •
