THE CANADIAN ENTOMOLOGIST. 189 



tigating its habits, preparing statistics of the losses occasioned by its 

 attacks, and testing the various remedies which have been suggested for 

 its destruction. In a circular issued in June last they solicit the co-oper- 

 ation of Entomologists, many of whom will, I trust, be able to render 

 them efficient aid in this good work. 



During the year death has removed from our ranks three well known 

 laborers in the Entomological field, Dr. Asa Fitch, late State Entomologist 

 of New York ; Dr. Heimann Loew, the eminent German Dipterist, who 

 has done so much to advance our knowledge of American Diptera ; and 

 Frederick Smith, the renowned English Hymenopterist. Thus year by 

 year we are called to mourn the loss of those whose names, for their 

 works' sake, we revere. They have gone to their reward ; we live to 

 labor. Let us each endeavor to make the best possible use of the time 

 and opportunities we have, however limited they may be, and diligently 

 and contentedly labor in the sphere in which God has placed us; prompted 

 by pure motives, may we with earnest effort probe deep into the secrets 

 of nature, and draw from thence treasures new, so that when we pass 

 away we may leave behind us some little lustre which may lend a light, 

 however dim, to those who will fill our places. 



I have the honor to be very sincerely yours, 



Wm. Saunders. 



ON THE PREPARATORY STAGES OF CERTAIN FLORIDA 



BUTTERFLIES. 



Editor Canadian Entomologist : 



I have received from Dr. A. W. Chapman, of Apalachicola, descrip- 

 tions of preparatory stages of several species of Florida butterflies, made 

 by him 1870-1872, with permission to publish such as I saw fit. I send 

 one instalment confined to the Hesperidae, and where it seemed desirable 

 I have added note > of my own in brackets. Except in case of Eudamus 

 Protcns, wherever Dr. Chapman has described larvae which are also figured 

 by Abbot, in Smith-Abbot, Insects of Georgia, or by Boisduval and Le- 

 Conte, after drawings of Abbot, the description differs essentially from the
