shamefully defrauded of the just reward for his great inven- 

 tion. But it gives me the greatest pleasure to state, that by 

 no possible word could I gather that Mr. Langstroth feels any 

 bitterness towards those who seem wilfully to have stolen his 

 invention, while with a mantle of charity, great as is his noble 

 heart, he covers the thousands who either thought he had no 

 valid claim, or else that the purchase of a right from others, 

 entitled them to his invention. As an inventor and writer oa 

 apiculture, Mr. Langstroth will ever be held in grateful

 he may be spared to us until he completes his autobiography, 

 that we may learn how he arrived at his great discovery, and 

 may study the methods by which he gleaned so many rich and 

 valuable truths. 



LECANIUM TULIPIFERiE— Cook. 



In the summer of 1870, this louse, which, so far as I 

 know, has never yet been described, and for which I propose- 

 the above very appropriate name, tulipiferjB — the Lecaniuni of 

 the tulip tree — was very common on the tulip trees about th'e- 

 College lawns. So destructive were they that some of the 

 trees were killed outright, others were much injured, and had 

 not the lice for some unknown reason ceased to thrive, we 

 should soon have missed from our grounds one of our most 

 attractive trees. 



Since the date above given, I have received these insects, 

 through the several editors of our excellent bee papers, from 

 many of the States, especially those bordering the Ohio 

 River. In Tennessee they seem very common, as they are 

 often noticed in abundance on the fine stately tulip trees of" 

 that goodly State — in the South this tulip tree is called the 

 poplar, which is very incorrect, as it is in no way related to 

 the latter. The poplar belongs to the willow family ; the- 

 tulip to the magnolia, which families are wide apart. In 

 Pennsylvania the louse has been noticed on the cucumber 

 tree — Magnolia acuminata. 



Wherever the tulip-tree lice have been observed sucking- 

 the sap and vitality from the trees, there the bees have alsoi
