LETTER OF TRANSMITTAL. 



Lincoln, Nebr., Nov. 20, 1889. 



Sir: In presenting a report on the insect injuries in Nebraska for the past spring 

 and summer, it is not in y intention to mention all the species that have been observed 

 in the act of depredating. Neither do I expect to enter upon a discussion of their 

 life histories. To do this would require altogether too much time and occupy con- 

 siderable more space than could be allotted to such iusects as have been repeatedly 

 described in your various reports upon injurious insects. Suffice it, then, for me to 

 mention briefly a few of the species that most attracted my attention, either by their 

 appearance in unusual numbers, their more than ordinary injuries, or by their pecul- 

 iar mode of attack. 



* 



During the year most of the well-known species that are always present in more or 



less injurious numbers, were noticed at their regular seasons of appearance. These 

 were, of course, expected; and, unless either very numerous or scarce, -were but little 

 noticed. Aside from these, few new or original observations were made during the 

 active season ; but several new enemies were observed to act in connection with old 

 and well-known forms. 



Since my last report, some time has been devoted to the Acrididw of North America, 

 in the continuance of our work upon that family of the order Orthoptera. The latter 

 work was chiefly in the line of looking up the matter of distribution, the character- 

 izing of new material, and the massing of such additional species as could conven- 

 iently be obtained without expense to the Department. Some little was also done in 

 this connection in the study of several minor locust outbreaks in different parts of 

 the country, as, for example, in Utah, Minnesota, and the White Mountain district of 

 the New England States. Of these different outbreaks you already have been ad- 

 vised ; Mr. Otto Lugger, of the Minnesota Experiment Station, reporting on that of 

 his State; Mr. C. L. Marlatt, that of New Hampshire, and myself upon that of Utah.

FALSE CHINCH BUGS. 



Early in the year, during the mouth of May, two or tbreespecies of small 

 hemipterous iusects began to gather upon several farms just outside 

 the city limits of Lincolu. These appeared in much larger numbers 

 than is usual for the insects under consideration ; and from their size,
