424 FIFTH REPOKT OF THE ENTOMOLOGICAL COMMISSION. 

 65. Phytoptua aceiicola Gariuan. 



This mite produces galls on the leaves of the sugar maple, Acer sac- 

 charimim Wang. 



In five examples of this mite the strise were counted, and in three of 

 them numbered 30, and in the other two 28 and 29, respectively. The 

 prongs of the feather-like appendage seem to be three. The length is 

 about .0075 inch. This form was found in June both among knobbed 

 hairs and in galls on the sugar maple, but there appeared to be only 

 one species represented. 



The gall is very slender, tapers to both extremities, and bears a 

 strong resemblance in general form to the nail galls described by Prof. 

 C. V. Eiley from the leaves of Ampelopsis. The walls are uniformly 

 thin, and present no internal roughness. The height is about .19 inch, 

 and the diameter .045 inch. Phytopti were abundant in these galls 

 collected at Bloomington, III., Juue 22, 1881. (Forbes' Third Report.) 



The following insects also occur more or less constantly on the maple : 



Order Coleoptera.*
