ENTOMOLOGICAL NEWS. 



[The Conductors of ENTOMOLOGICAL NEWS solicit and will thankfully receive items 

 of news likely to interest its readers from any source. The author's name will be given 

 in each case, for the information of cataloguers and bibliographers.] 



To Contributors. All contributions will be considered and passed upon at oui 

 earliest convenience, and, as far as may be, will be published according to date of recep- 

 tion. ENTOMOLOGICAL NEWS has reached a circulation, both in numbers and circumfer- 

 ence, as to make it necessary to put " copy " into the hands of the printer, for each num- 

 ber, three weeks before date of issue. This should be remembered in sending special or 

 important matter for a certain issue. Twenty-five " extras," without change in form, 

 will be given free, when they are wanted ; and this should be so stated on the MS., along 

 with the number desired. The receipt of all papers will be acknowledged. ED. 



PHILADELPHIA, PA., JUNE, 1909. 



Upon careful estimation it was found that the total value of 

 crops raised in the State of Pennsylvania, during' the year 1908 

 amounted in value to over one hundred and seventy million 

 dollars ($170,415,840). This was for barley, buckwheat, corn, 

 hay, oats, potatoes, rye, tobacco, and wheat. The value from 

 fruit culture, flowering plants, trees and shrubs we do not 

 know. It has been estimated that insects take a toll of one- 

 tenth, and on this basis the amount of money loss on the 

 crops alone would be nearly nineteen millions of dollars in 

 this one State. The value of economic work in entomology 

 is rapidly becoming appreciated in Pennsylvania, and in fact 

 all over the United States, but there is much to be desired. 

 One thing that Pennsylvania needs is a list of its species of 

 insects similar to the admirable one gotten out by Prof. John 

 B. Smith, State Entomologist of New Jersey. Such a list 

 would be a great aid and stimulus to entomologists and would 

 encourage the non-professional collector. The New Jersey 

 list has been a great stimulus and in time many States will 

 publish lists of insects. Irrespective of value in economic 

 work, geographical distribution and the other scientific studies 

 are advanced by such compilations. 



THE associate editor of the NEWS, Dr. Philip P. Calvert, has hecn 

 granted leave of absence until October T. 1910, by the University of 

 Pennsylvania, where he is Assistant Professor of Zoology, to enable 

 him to go to Central America to pursue further researches on the 

 ecology of tropical Odonata. This is in continuation of the studies 

 which have grown out of his preparation of the account of these in- 

 sects for the "Biologia Centrali-Americana." Dr. and Mrs. Calvert 

 sailed from New York on April 17 for Costa Rica. Their permanent 

 address is 635 North Sixteenth Street, Philadelphia, Pa.
