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

 tribution, ranging, according to Linell, from the East to Nebraska and Texas. 



Remedial measures. There is no reason why this species, when abun- 

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

 oughly spraying the infested foliage with an arsenical poison, preferably 

 arsenate of lead. 



Conotrachelus anaglypticus Say 



A small, long-snouted weevil about 3/ x6 inch long, with strongly ridged elytra and 

 prettily marked with dark brown, yellowish white and reddish brown (the latter forms a 

 large spot near the anterior lateral margin of the elytra and nearly covers the posterior 

 lourth) occurs on elm. 



This species 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 plant. 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 Adirondacks. 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 vicinity of Cincinnati.

Polygonia intcrrogationis Fabr. 

 A red-headed, black-spined caterpillar about 1 inch long, feeds on elm foliage. 

 This species is one of our common butterflies and occasionally its 

 larvae become somewhat abundant and destructive to elm. It is easily
