The species of this genus are all nut-weevils, and those that feed in 

 hickory and chestnut are often seriously injurious. The chestnut weevils 

 in New Jersey are especially troublesome where the European and Jap- 

 anese varieties are grown. There is no insecticide that is available to 

 reach the insect in any stage, and the only methods of control are to 

 collect the nuts as soon as they fall and market them, or to store them 

 in tight barrels, from which the larvae cannot escape when they emerge 

 from the nuts. 



Family BRENTHIDyE. 



Contains only a single very curious species, in which the males have 

 prominent mandibles at the ends of the short robust snout, and the 

 females have long, cylindrical beaks, by means of which they bore into 

 the wood to lay their eggs. When these beaks become wedged, as they 

 sometimes do, the males use their forceps-like jaws to pull them out. 



EUPSALIS Lee. 



E. minuta Dru. Throughout the State on chestnut, oak and maple;, 

 hardly common anywhere.
