I06 MAINE AGRICULTURAL EXPERIMENT STATION. I915. 



This form indicated by Say as a varietj- of octoUneata and later 

 described as a distinct species by Fitch is difficult to separate if long 

 series are in hand but there is hardly such complete gradation from one 

 to the other, especially as represented in Maine, as to warrant absolute 

 merging of the two forms into one species. Specimens of this form 

 have been collected at Orono, Portland Aug. I3-I4th, Highmoor Farm 

 Aug. 15th. It is usually taken from trees and has not in any case I 

 believe been collected from bogs. It is usually less abundant than 

 octoUneata and so far as observed hardly plentiful enough to be counted 

 of much economic importance.

Light yellowish green with a slight bronz}- tinge especially after dry- 

 ing. The elj-tra are only faintly reticulate at tip not at all on olavus or 

 base of corium. Smaller than the other species known in Maine. Length 

 $ body 7 mm. to tip of elytra 8-9 mm. S body 6.5 mm. to tip of elytra 

 8 mm. 



One specimen determined by Van Duzee bears date of Sept. 10, 1905, 

 and specimens have been taken during 1913 at Orono Aug. 5th, High- 

 moor Farm on blueberry Aug. 15th, Grand Lake Stream Aug. 15th by 

 Prof. A. P. Morse, Mt. Katahdin Aug. 22nd, Houiton Aug. 24th, Ft. 

 Kent Aug. 28th. While specimens have been taken in a number of situ- 

 ations and from a variety of plants this species has appeared especially 

 common in low ground and boggy places and a number were collected 

 in the bog south of Orono and at Houiton on plants growing among 

 the sphagnum. There are some puzzling variations in the amount of 

 elytral reticulation but there seems to be a fairly constant general facies 

 upon which one can separate this form from the others occurring in 

 the state. One specimen, also referred to this species, {quehecensis 

 Prov?) is smaller and darker green with very few reticulations at tip of 

 elj^ra, taken from poplar July 30th at Orono. 



Except for its occurrences on blueberry the species has not been noted 

 in sufficient numbers on any plant of economic value to be counted 

 injurious in an^' of the collections this season.
