The return journey was made without especial interest. 

 " Emerson," our driver, met us promptly with the buckboard ; 

 and what with fishing and " butterflying " the journey seemed 

 short indeed. I added some good specimens of D. portlandia 

 to va.y captures, besides many more common ' ' flys. ' ' 



In all we were gone fifteen days from Boston, and were 

 glad to get back to civilization and away from the black-flies, 

 and sleep once more in a real bed. 



In conclusion I wish to thank Mr. Emile F. Williams for 

 much valuable information, the result of his trip to Mt Katah- 

 din in 1900, and Dr. Henry Skinner for his kindness in helping 

 me to determine that I had a new species in Chionobas katahdin. 



The Greenhouse Coccidae, L 

 By Geo. B. King, Lawrence, Mass, 

 The introduction of scale insects by the means of man, that 

 is to say by the importation of greenhouse plants, seems to be 

 increasing yearly, and a list of such species as have already 

 been recorded or known to infest greenhouses I have thought 

 should be brought together and published for the benefit of 

 Economic Entomologists and Horticulturists. My residence in 

 a city where there is no library treating upon or in any way 

 assisting one in Entomological research work has compelled me 

 to depend upon my own private library. It should therefore 

 be clearly understood that the following list of greenhouse 

 coccids is far from being complete ; and it is to be hoped that 

 more interest will be taken in this very important branch of 

 Economic Entomology. Any information concerning these 

 pests in greenhouses will be thankfully received by me, and 

 due credit given. Prof. Cockerell some two or three years ago 

 kindly sent me a list of greenhouse coccids recorded by Signo- 

 ret to inhabit greenhouses in Europe. The number of species 

 given was 45. We now know of 64, and of this number only 

 one species as yet can be called a native of this country ; 

 several scales have been described from greenhouses in America, 

 whose nativity are unknown at present. It may be that 

 Mytilaspis gloveri Pack, is a native species, and we do know
