they are infested by the yrubs. This method has been successfully employed 

 in Germany, for the control of beetles possessing similar habits.

Reddish elm snout beetle 



Maoda/is ariii/cfl/Iis Say 



This beetle may be distinguished from the preceding by its reddish 

 color. It has been reared in small numbers by the writer from American elms 

 growing at Berlin Mass., and in larger numbers from the same wood received 

 through Mr M. F. Adams of Buffalo. It has also been obtained from elms 

 by several other entomologists. Dr Horn states that this form occurs with 

 the preceding and this accords with experience of other entomologists. Its 

 life history, so far as known, is practically the same as that of M. barbi t a 

 Say, and the remedial measures of value against the preceding species would 

 doubtless prove of equal service in the case of this insect. 



Leopard moth 

 Zetizcra pyrina Fabr. 



Dead limbs, projecting above leafy branches or broken and hanging in the midst of 

 otherwise healthy trees are the most conspicuous signs of this insect's work. 



Dead limbs may frequently be seen projecting above the leafy masses 

 of many trees in New York city and vicinity. These and the sudden wilt- 

 ing of living ones are, in many cases, the effects of the destructive work 

 of^he leopard moth caterpillar. This is probably the worst insect enemy 

 of shade trees in the vicinity of New York city. It not only bores in slen- 

 der twigs, but as the caterpillar increases in size, it enters larger limbs and 

 before attaining its growth frequently intlicts serious injury on the trunk. 



Description. This insect is most easily recognized in connection with 

 its work. Boring within the smaller twigs, there may be found a pinkish or 

 white caterpillar\bout -> « inch long, with numerous well defined, darker
