ovipositor, and during tliis latter move- 

 ment the anal cerci tremble slightly. 

 Two opeiations, including both drilling 

 and oviposition, which were timed, took 

 six and a half and five and a half 

 minutes respectively. As soon as one 

 egg is laid, the female proceeds to attack 

 the hark again in a new place at a very 

 short remove from and above the other, 

 and uses the bits of bark torn oft' to 

 conceal the opening of the hole below, 

 fastening them in place by the aid of its 

 "molasses," so that when it hardens it 

 presents the rough appearance one 

 always sees at the entrance ; but if these 

 are removed the opening of the hole 

 will be found clean and splinterless. 

 The insect bores but two or three holes 

 at a time and after a delay returns to the 

 same spot to renew operations, mean- 

 while leaving the uppermost hole 

 unplugged, although those below are 

 often revisited in the pauses of oviposi- 

 tion to spread more fluid on the other 

 completed drills. This explains why 

 the uppermost drill of a series is often 

 found unclosed at the opening, the 

 insect having perhaps been frightened 

 away altogether before the entire com- 

 pletion of her task. 



The egg-holes are drilled at an average

of I . I mm. apart and are 0.4 mm. in 

 diameter at the entrance. The harder 

 outer portion of the stem of the rasp- 

 berry is first bored through almost 

 vertically but a little downward, while 

 in the pith the drills incline downward 

 in a slight curve (just that of the egg), 

 the general trend of the deeper portion 

 being at angles varying from 135° to 170° 

 but averaging about 14s to .the trend of 

 the initial portion. 



The eggs are nearly cylindrical, taper- 

 ing slightly and well rounded at the 

 ends, both ends alike in this respect, 

 2.65 mm. long and 0.55 mm. broad, 

 the top end, occiipving a length of two- 

 fifteenths of the whole, covered with 

 little crowded papillae ^vhich diminish 

 in size away from the tip, and where 

 they fade the surface becomes studded 

 with lozenge shaped depressions 0.017 

 mm. long and half as wide. When first 

 laid the eggs are of a imiform very 

 pale green, but later become brownish 

 amber or pale brassy, Init with a pale 

 brownish yellow la3'er at the lower 

 end. The eggs are extruded cap-end 

 hindmost. 



This insect seems to prefer to eat the 

 harder parts, the ribs and veins, of 

 leaves.
