as preying on tlic larvae of this leaf feeder. This species has an extended dis- 

 triJKition, ran^in^-, according;- to Linell, from the PLast to Nebraska and Texas. 

 Remedial measures. 1 here is no reason why this species, when aliun- 

 dant, can not be controlled as in the case of other leaf feeders, by thor-

Conotrachelus anaglypticus .Say 



A small, l(ini,»-siiouted weevil about s/g inch long, with strongly ridged elytra and 

 prettily marked with dark hrown. yellowish white and reddish brown (the l.itter forms a 

 large siiot near the anterior lateral margin of the elytra and nearly covers the jjosterior 

 I'onrth) occurs on elm. 



This s|3ecics was taken by Mr Young, at Poughkeepsie, June 5 and 6, 



on slippery elm. The occurrence of the weevil on two successive days on 



this tree, would indicate a certain attraction for 

 this food jjlant. The tree had been stripped of 

 bark and the surface was dry though the leaves 

 were green. Mr Young has also taken this species 

 in the .\dirondacks. Say records taking many 

 specimens on a hickory, and states that they 

 oviposit in the fruit. This species has been 

 recorded by Dr LeConte, as abundant from 

 Massachusetts to Kansas, Georgia and Texas. It 

 has been listed as occurring on walnut through- 

 out New Jersey, and Ulke states that it commonly 



occurs in the District of Columbia, under moist bark and on various bushes. 



Dr Horn records it as common in southwestern Pennsylvania, and Dury has 



listed it from the \'icinity of Cincinnati.
