Limbs taken from the sprayed trees and checks showed that tlie lime-sulfur 

 wash killed no scales, while the kerosene emulsion destroyed practically all.

Membracid Eggs in an Apple. In November, 1908, from Des Moines, Iowa, 

 I received an apple which had in its skin a number of Membracid egg pouches 

 similar to those made by Ceresa taurina Fitch. These pouches were just 

 beneath the skin of the apple and nineteen were counted when the ap- 

 ple was received. Several had already been removed by the sender, Mr. 

 W. H. Kinkennon, who first noticed them. A row of thirteen extended in a 

 nearly straight line from the "equator" of the apple to a point near the calyx, 

 with six more in a line part way around the calyx end. All of the pouches 

 were placed with the long axis parallel to that of the apple. The egg pouch 

 itself was an oblong swelling in the skin of the apple, having a small slit 

 lengthwise at the lower left-hand side (the apple with the stem end upwards). 

 There was no discoloration of the apple skin in the vicinity of the egg pouches. 



The following measurements, made with a Leitz compound microscope 

 (objective 2, ocular 3), were taken from one of the egg pouches: The pouch 

 was 2.54 mm. in length ; from .43 to .54 mm. wide, the narrow measurement 

 taken at the end with the slit ; the slit itself, 1.08 mm. long. Away from the 

 slit the pouch widens slightly, as the measurements show, and make the slit 

 somewhat pear-shaped. The egg itself is pale, almost translucent, and ap- 

 pears broader at the end farthest from the slit. The measurements taken 

 of the egg are as follows: Length, 1.81 mm.; width, .35 to .47 mm. 



The apple containing the eggs was sent to Professor Herbert Osborn, who 

 confirmed the opinion of the writer, that the eggs were those of some Mem- 

 bracid, and possibly those of Ceresa taurina Fitch.

Anthrenus verbasci Linn., a common museum pest, feeds, as is well known, 

 upon a considerable variety of dry animal and vegetable substances. April 

 4, 1902, two ears of corn infested by this insect were received and placed in a 

 2-quart Mason jar and kept tightly closed, with no moisture aside from that in 

 the somewhat dried com. Breeding has continued apparently uninterrup- 

 tedly during a period of seven years. The bottom of the jar is nearly covered 

 with fine, white globose particles, apparently starch grains falling from the 

 eaten kernels of corn and a thick mass of the brown larval skins and other 

 debris. It appears from the above that this insect is capable of breeding for 

 an extended series of years under such adverse conditions.
