there were numbers about the tree, it was five minutes before one 

 aHghted upon the sprinkled leaves. It appeared to feed and then 

 walked about on the leaves and finally came to rest. It was observed 

 for some thirty minutes moving about normally and then suddenly 

 disappeared. A serious defect in the mixture is the rapidity with 

 which it dries. It was found that individual flies could be captured 

 by bringing the fingers near to the insect and then as it lit there- 

 upon suddenly closing them. Subsequently it was found that the 

 flies were attracted to the fingers probably because they were stained 

 with cherry juice. This suggests that the poisoned bait mentioned 

 above might be made more effective by the addition of some such 

 flavor. 



The evidence obtained the past season, while far from being as 

 satisfactory as one would wish, is certainly not very promising so 

 far as this poisoned bait is concerned. It is probable that our cherry 

 growers will find a large measure of relief, if not practical immunity 

 from injury, by picking cherries as soon as they are ripe and taking 

 special pains to secure all the fruit, thus reducing the opportunities 

 for the breeding of the flies and consequently lessening the danger 

 of trouble the following season. We are inclined to believe that so 

 far as this insect is concerned, prompt and thorough harvesting will 

 aft'ord a practical solution of the difficulty. Injury by plum cur- 

 culio, an associate of the cherry fruit fly, can be controlled by per- 

 sistent use of the beetle catcher or the employment of a poisoned 

 mixture such as that used by Mr Miller the past season. 



Lined red bug (Lygidea mendax Reut.).^ Several 

 years ago the late Professor Slingerland noticed briefly, as an apple 

 insect, a small, red Hemipteron under the popular name of red bug 

 (H eterocordylusmalinus Reut) . The form under dis- 

 cussion is very similar in appearance to the earlier described species, 

 though easily separated therefrom by the much more prominent 

 eyes and especially, as pointed out by our wellknown authority in 

 this group, Mr E. P. Van Duzee, by the black line along the pos- 

 terior margin of the pronotum. 



The work of this new apple pest may be observed during May 

 and early June on the three or four terminal, more tender leaves. 

 These are more or less curled and frequently form partially inclosed 

 retreats containing a brilliant red, partly grown bug. It is probable 

 that this species injures the fruit as well as the red bug. The 

 affected leaves have much the appearance of being injured by plant
