specimens to Mr. Cockerell who pronounces it an undescribed 

 variety. Mr. Cockerell has kindly sent us a MSS description 

 which we incorporate in the body of the report. 



There has been considerable complaint about an insect that 

 destroys the terminal buds of gooseberry canes causing the growth 

 of numerous small lateral shoots in a cluster near the ends of the 

 branches. The specimens sent us this year and last were not 

 accompanied by any live insects, but as the leaves showed numer- 

 ous molt skins we concluded it must be the work of Myzas ribes^ 

 The Gooseberry Plant-Louse. 



The Cabbage Butterfly {Pier is rapre) is very abundant in 

 Maine and interferes seriously with the culture of cabbage. There 

 are various subtances that can be applied to check this pest, but 

 none are effectual except arsenical compounds applied as spray, or 

 in the form of powder. As arsenic is poisonous it should not be 

 applied after the heads are a third grown. 



We receive occasionally a large pale green moth with long tails 



to the hind wings. This is the Luna Moth, a night flying species, the 



larvffi of which feeds upon the walnut and hickory and no doubt other 



plants, as it is rather common about Orono and there are no native 



• walnuts or hickories. 



The Oblique-banded Leaf-roller does considerable damage to 

 currants and raspberries and other plants of the Rose family. 



We receive the Cecropia Emperor Moth so often that it is 

 regarded best to publish cuts of this conspicujus species which 

 feeds upon the leaves of apple trees. 



The Chinch Bug which is found over qu'te a large area in the 

 vicinity of Fryeburg has done quite a good deal of damage annually 

 to grass lands after haying for a great many years. It is not 

 confined to the intervales about Fryeburg, but it has been reported 

 from Bridgton on the east and from the vicinity of Bethel twenty- 

 five miles to the north. 



We received specimens of a Hawk Moth known as (Snierinthus 

 cerysii) from Mr. A. N. Townes, Winthrop, Me. This is a rare 

 species and we mention it on this account. The early stages in its 

 life history have never been published. We secured a large number 

 of fertile eggs and have been able to rear the insects and make 

 notes upon all the stages. Prof. Braun of Bangor, and Mr. Ora 

 Knight, one of my pupils, have aided in the study. The notes will 

 be contributed to some Entomological Journal. The species feeds 

 upon the willow and poplar.
