some of the measures which he had found most satisfactory in treating 

 those insects that were most troublesome in the parks. He finds that 

 there is very little difficulty in controlling the insects, provided a sufficient 

 force and a sufficient quantity of apparatus is placed at the disposal of the 

 entomologist. 



Dr. Lintner read a paper upon " Lina scripta," and described the injury 

 done by the beetles and its larvae on basket willow in Onondaga County, 

 N. Y. The most practical methods of preventing injury thus far have 

 been mechanical, and consisted in a sort of modification of the hooper 

 dozer, adopted for the particular purpose, but a considerable amount of 

 injury seems to be done each year, for which no remedy is yet at hand. 



Mr. G. C. Davis read a paper on the " Insects of the Season in Michi- 

 gan," in which he called attention to a considerable number of species 

 that had been unusually troublesome, and among others the climbing cut 

 worms, which have been especially hard to deal with in certain orchards. 

 The application of the poisoned bran mixture at the base of the trees had 

 been on the whole the most successful, and he had found, by direct ex- 

 periment, that the addition of sugar to the bran and Paris green did not 

 increase its attractiveness. He also described the injuries done by species 

 of 3Ionarthruin on peach trees, and described the curious appearance of 

 the roots of the infested trees. On this point there was some discussion 

 as to whether the attacks by the beetles were really the primary causes 

 of the injury, and it was questioned whether the attacks in the trunk 

 would produce the abnormal appearance in the roots. Mr. Smith sug- 

 gested very pointedly that the injury to the roots might easily have been 

 primary and the attacks of the Scolytid the secondary consequence. A 

 paper on " The study of Forest Tree Insects" was presented by Mr. Hop- 

 kins, and read in his absence. It is the same paper that was presented 

 before the Association of Agricultural Colleges and Experiment Stations, 

 to which reference has been made in a previous number of this journal, 

 and was interesting from the estimate of the money value of the injury 

 done each year by insects a question upon which some difference of 

 opinion was expressed. 



A paper from Mr. F. H. Chittenden, on the "Herbivorous habits of 

 certain Dermestidae" contained an interesting record of observed food 

 habits of many of our species, showing that the generally accepted state- 

 ments concerning their food must be considerably qualified. In the dis- 

 cussion a number of confirmatory facts were brought out and a readiness 

 to accept Mr. Chittenden's conclusions was manifested, largely based 

 upon the personal experience of members. Incidentally, the methods to 

 be adopted in the case of the imported carpet beetle, Anthrenns scroph- 

 ularuc were discussed, and Dr. Lintner protested vigorously against am- 

 use of the term " Buffalo moth" even in a popular reference to this insect. 



Mr. Webster presented a paper on "Some Interesting Facts Regarding 

 the Genus Diabrotica, " in which he traced, rather carefully, the distribu- 

 tion of the various species in the United States, their relationship to each
