Department of Agriculture at Washington, his statement con- 

 cerning the winter egg being as follows : 



"The winter egg was found on several occasions during the winter 

 in crevices of the bark over which a colony had been stationed during 

 the summer. It was a rather long ovoid, measuring .322 mm. (.125 inch) 

 in length and was very similar to the winter egg of Colopha ulmicola 

 (Fitch), as described by Riley in Bulletin No. I, Vol. V, Hayden's 

 Survey. 



"This egg was laid, as Professor Thomas supposes, by a wingless 

 female, differing from the ordinary agamic form to a certain extent. 

 These females we only know from finding their skins around the 

 winter egg, since they often die without depositing it. The males we 

 have not seen." 



An attempt was made to include in the bibliography of Bul- 

 letin 203 of the Maine Agricultural Experiment Station refer- 

 ences to all original observations on the Ulmus-Pyrus Schi- 

 zoneuran but other omissions besides the interesting note just 

 quoted may have occurred in which case addenda from any one 

 noticing them would be very gratefully appreciated. 



LEPIDOPTERA. 



BUTTERFLIES AND MOTHS. 



Euvanessa antiopa. 

 THE YELLOW EDGE BUTTERFLY. 



Specimens of the larva of this insect were perhaps more 

 frequently received for identification by the Station this year 

 than any other single species, as it was unusually abundant in 

 many parts of the State. The eggs are yellow with white ridges 

 and are attached in masses encircling the twig. Such a mass 

 was found near the swelling leaf bud of elm, May n at Orono. 



As a circular descriptive of this insect may be had upon 

 application to the Station further details are here omitted. 



Ctenucha virginica. 



THE VIRGINIA CTENUCHA. 



This beautiful little moth, with its blackish wings extending 

 from i 3-4 inches to 2 inches, peacock blue body and red head 

 makes it a conspicuous object (fig. 493.) It is not uncommon 

 in Maine, and was unusually abundant this season. The larva 

 somewhat resembles that of the spotted tiger moth, but like
