AGRICULTURAL EXPERIMENT STATION. 93 



"Your No. 3, is something of a puzzle. The gall is like that of the 

 ordinary Rliodites rosae, but insect differs in the very important 

 respect of totally lacking the parasidal sutures, a character -which is 

 at least of specific importance." We do not know whether the species 

 was afterwards considered by Prof. Eiley, nor what was done with 

 the specimens. We did not study the insect further, and have 

 not noticed the galls so abundant since. It is interesting to have the 

 same galls reported from another locality, Mattawamkeag, Maine. 



The black oak trees in Maine are often infested by a g*all fly which 

 produces large knotty excrescences on the branches, which are full 

 of small holes after the insects have emerged. We have examined 

 galls sent by Mr. Stover of Blue Hill, and find the species producing 

 them is called by entomologists, Callirhytis piinctatus, Bass. 



The Horn-tailed Borer, a large species of saw fly that makes 

 round holes about the size of a lead pencil in various trees was 

 reported as laying its eggs in a maple tree. 



The Apple Maggot, (Trypeta Pomonella) continues to be a great 

 pest. It is spreading. Several parties have reported that by keeping 

 the windfalls picked up or by keeping sheep in the orchard they have 

 held it in check. As long as early apples are imported from Massa- 

 chusetts, more or less infested with the larvae of this pest, our 

 Maine towns •will continue to be centres for the distribution of 

 Trypeta. 



The Buffalo Carpet Beetle seems to be spreading, having been 

 reported as very abundant in Saco, South Litchfield and Bangor.
