of from seven to twenty-one punctures. Occasionally the number 

 of eggs in a series was increased over night or over a succession of 

 nights at varying intervals by ovipositions by the same female. 

 Observations in a patch of raspberries showed that the number of 

 eggs in a row ranged from two to eighty-seven. The average number 

 in nineteen rows taken at random was about thirty-two eggs. The 

 longest row found in a willow twig had eighty-seven egg punctures, 

 which strangely enough are also the highest figures for oviposition 

 in raspberries. 



The eggs are placed in rather compact rows with from seven 

 to ten punctures to each centimeter. They lie in a slanting direction 

 across the central pith cavity, the angle being about 40 to 50 degrees, 

 depending somewhat on the diameter of the stalk. (Fig. 34, b.) 

 The capped end of the egg lies within one or two millimeters from 

 the opening of the hole and the egg usually slants downward from 

 the opening instead of upward, since the female normally stands 

 head up while ovipositing. When the rows are compact the eggs 

 are generally directed alternately to the right and left so that they 

 do not interfere with each other. In plants with a large pith cavity 

 the eggs lie wholly within that part, but in those with a small central 

 pith the cap end is partly imbedded in the woody tissues. The 

 oviposition period for this cricket commences during the latter part 

 of August and may extend through the month of September. 



plants selected for oviposition. 

 This species prefers for the reception of its eggs plants which 

 have a central pith surounded by a woody outer layer, and there are 

 a great many plants of this character which are selected by the insect 

 for this purpose. Eggs are deposited most abundantly in raspberry, 

 blackberry, Erigeron canadensis and the larger species of Solidago. 

 They are also common locally in elder, grape, sumac and willow. 

 A few eggs may occasionally be found in the twigs of peach 2 (Plate 

 XXXVI, fig. 1), apple, 3 elm, maple and hickory. Mr. Goodwin of the 

 Ohio Station writes that considerable oviposition by this species 

 occurs in peach orchards and vineyards in northern Ohio, especially 

 on trees and vines which adjoin uncultivated fields. Similar con- 

 ditions with respect to vineyards have been noted in the grape- 

 growing region in Chautauqua county, New York. Mr. W. T.
