THE TEAR'S INTERMISSION. 



Wo have been highly pleased at the numerous 

 gratulatoiy letters which have come to hand 

 since our last number was sent out. General 

 regret is expressed, and some few of our sub- 

 scribers express the fear that the publication of 

 our journal will never be recommenced. Indeed, 

 some of our contemporaries have even apnounced 

 that the "American Entomologist and Botan- 

 ist has been discontinued." Now we must here 

 reiterate that which we have already announced. 

 Our journal is not discontinued, but simply sus- 

 pended for one year, in accordance with the 

 desires of both publishers and editors. Like 

 those insects which, after an active lai-val period, 

 go through a pupal stage during which the life 

 functions are in great part suspended, and which 

 yet afterwards bm-st forth in all their glory and 

 lerfection; so we intend that our journal, after 

 s temporary suspension, shall in due time ap- 

 ear, before those who signify their desire to 

 eceive it, in a more attractive and perfect form. 

 It is because of this our firm intention that we 

 lesire all those who contemplate taking Volimie 

 ill to send in their names (not the money) at 

 once to the publishers. The greater the Kst the 

 nore we shall feel encouraged to go on, and 

 3very present subscriber who desires the success 

 )f our enterprise should endeavor to send in at 

 east one more name with his or her own. 



In taking temporary leave of our readers we 

 ;annot forbear to express om- sincere thanks to 

 hose editors who have so fsivorably noticed tins 

 laper, and to the many friends who, by their 

 ■ontributions and aid in other ways, have laid 

 lis under lasting obligations. 



Bound Volumes. — The publishers will furnish 

 this volume complete and nicely bound for $2.50 

 per copy. Only about 20 copies of Vol. I remain, 

 disposed of at the same price.

INSECTS INJURIOUS TO THE GRAPE- VINE.- 



The Grape-leaf Gall-louse, 



{Phylloxera vi(i/oli<E, Fitch.) 



Color — Green. 



Here we have an insect, the life-Mstory of 

 which is as interesting to the entomologist as its 

 devastations are alarming to the grape-gi-ower. 

 We have given it considerable attention the past 

 summer, and though it is a difficult task to pre- 

 sent definite and satisfactoiy information from 

 among the multitude of facts we have obtained, 

 yet we shall endeavor to lay before our readers 

 a comprehensive account of this little louse, so 

 far as our present knowledge of it will permit. 

 In doing so we are made painfully aware that 

 there is much room left for further obsei-vations, 

 and he who will patiently and persistently devote 

 his time for a few years to its study, and will 

 with candor and accuracy give to the world the 

 results, will doubtless be rewarded by new and 

 important discoveries, and will render valuable 

 sei-vice to the cause of science and of economic 

 entomology. 



The first reference to this insect was briefly 

 made by Dr. Fitch, of New York, in the year 

 1856,* and he subsequently described it in a very 

 insufficient manner, under the name of Pemphi- 



T. Eep.
