LIST OF PUBLICATIONS OF THE ENTOMOLOGIST 



The following is a list of the principal publications of the entomologist 

 during the year 1898, 73^ are named, giving title, place and time of 

 publication and a summary of the contents of each. 

 Corn-root worms. (Country gentleman. Feb. 10, 1898. 6^: 107, col. 



I, 2 — 16 cm) 



From reading an account of the life history and habits of Diabrotica longicornis 

 Say, a correspondent is led to inquire as to the identity of an insect which operated 

 destructively on corn at Colora, Md., in 1895. In reply it is stated that the author of 

 the attack is most probably the southern corn-root worm, Diabrotica i2-punciata 

 Oliv., and preventive measures are given. 



Kerosene emulsion. (Country gentleman. Feb. 17, 1898. d^^'. 126, col. 

 4— 10 cm) 



Directions are given for the preparation of the standard kerosene emulsion, and 

 its proper dilution for use against several insects indicated. Continual experimenting 

 to find the best strength for different insects and plants is recommended, and the 

 method of application given. 



Scurfy bark louse. (Country gentleman. Feb. 17, 1898. dT,-. 127, col. 

 I — 10 cm) 



A small piece of apple-tree bark from a correspondent in Babylon, N. Y., was 

 found to be infested with Chionaspis fiirftints Fitch. The scale is briefly described 

 and the application in June of kerosene emulsion or whale oil soap solution recom- 

 mended for its destruction. 



A very different bug. (Country gentleman. Mar. 3, 1898. dy. 166,167, 

 col. 4, I — II cm) 



A correspondent in Wyncote, Pa., sends an example of the two-spotted lady-bird, 

 Adalia bipicnctata Linn., and inquires if it is the Buffalo carpet beetle. The chief 

 characters of this Adalia and of the Coccinellidae in general are given, and their 

 beneficial habits mentioned. The carpet beetle, Anthreniis scrophidariae Fabr., is 

 briefly described. 



Two bad insects. (Country gentleman. Mar. 17,1898. 63: 206, col. 

 3, 4—19 cm) 



Apple twigs infested with the apple-tree bark louse, Mytilaspis pomorum Bouche, 

 and others with the San Jose scale, Aspidiotiis perniciosus Comst., were received from 

 Brewster, N. Y, The climate of this state is congenial to the latter scale, as is 

 shown by its large numbers at East Greenbush, N. Y., and its known distribution in 

 the state is given. Badly infested trees should be burned — reference is made to the 

 directions for using kerosene and remedies given for the apple-tree bark louse.
