TENTH REPORT OF THE STATE ENTOMOLOGIST 359 



with rubber as soon as it can conveniently be done. In the 

 Hymenoptera, the Andrenidce^ which have been gradually accu- 

 mulating for a number of preceding years, but left unstudied from 

 the difficulty attendant upon their close resemblances, have been 

 carefully studied and all — so far as it could be done — deter- 

 mined and labeled. The Ajpidce have been partly gone over in 

 the same manner. In the Diptera special study has been given 

 to the interesting family of Bomhylidcn, and most of them have 

 been named. In the Orthoptera all of the AcrididcB have been 

 studied and their determinations made. Work of this character 

 is necessarily slow, but it will be carried on as rapidly as the 

 time that can be devoted to it will permit, with the view of put- 

 ting the entire collection in such shape that the duplicates that 

 are accumulating may be named and labeled, and ready for dis 

 tribution to the educational institutions of the State whenever it 

 shall be feasible to enter upon so desirable a work. With the 

 increasing attention that is being given to the study of natural 

 history in our schools, a series of cases representing typical insects 

 in each of the seven older orders, and another series to illustrate 

 the more injurious species, with their transformations and their 

 injuries — all authoritatively labeled, could not but prove a valu- 

 able contribution toward the educational material of the schools. 

 It is specially desirable that such collections, and still more 

 extended, should be placed in each of the ]S"ormal schools. Some 

 of them are already provided with them, and are giving valuable 

 instruction in entomology. The study of injurious insects, the 

 nature of their injuries, and methods for preventing their ravages 

 has, during recent years, become so indispensably connected with 

 successful agriculture that the demand will soon be imperative 

 for instruction in economic entomology in our principal schools. 

 Teachers, therefore, should be in training that may be prepared 

 to respond to such demand.
