ENTOMOLOGICAL NOTES FOR THE SEASON OF 1802. 



By Mary E. Murtfeldt. 



LETTER OF SUBMITTAL. 



Kirkwood, Mo., Novembers, 1892. 



Sir: I herewith submit such of my entomological notes for the past season as 

 relate to species of economic importance, including accounts of a few species that 

 have not hitherto been included in that category. I hav.e been much interested in 

 the study of several other species, also pernicious or beneficial, but as these have not 

 yet reached full development, I beg to reserve my notes upon them until I shall be 

 able to complete the record. 

 Respectfully, 



Mary E. Murtfeldt. 

 Dr. C. V. Riley. 



U. S. Entomologist. 



MISCELLANEOUS MEMORANDA. 



The climatic peculiarity of the past season throughout the Missis- 

 sippi Valley was found in the excessive rainfall and the low temperature 

 of the spring and early summer. That these conditions would produce 

 a noticeable effect upon insect life can not be doubted. Wheat fields 

 and corn lands that were inundated during April and a part of May, 

 so far as I have been able to ascertain, entirely escaped attack from 

 Chinch Bugs and Bill Bags. I am also inclined to ascribe to the same 

 cause the somewhat remarkable non appearance of the Colorado Potato- 

 beetle over a wide area of the country. So absolute was this disap- 

 pearance that repeated and careful search in this locality for specimens 

 upon which to test insecticides failed to reveal a single beetle or larva. 

 I can not say, however, that the potato crop was the better for this 

 immunity. The plants seemed sufficiently vigorous, but the. tubers 

 were few and small and the crop in Missouri almost a failure. 



Another insect that seems to have mostly deserted this section of the 

 country is the Grape Phylloxera. For two or three seasons I have not 

 noticed any galls on the leaves of even the most susceptible varie- 

 ties, and examinations of the roots of Delaware. Taylor, Catawba, and
