chusetts to protect the orchard and shade trees, that are properly cared 
for by their owners, from insect pests which are permitted to breed un- 
restricted in public highways and waste places. 
The act in full is reprinted herewith : 
AX ACT to provide for the Extermination of Insect Pests. 
Be it enacted, etc., as follows: 
Chap. 78, Section 1. Cities and towns shall raise annually- by taxation and appro- 
priate such a sum of money as they may deem necessary, to be expended under the 
direction of the mayor and aldermen in cities and the selectmen in towns, in exter- 
minating insect pests within the limits of the highways in their respective cities and 
towns, and in the removal from said highways of all trees and shrubs upon which 
such pests naturally breed : Provided, however, That where the owner or lessee of real 
estate abutting on the highway shall annually exterminate all insect pests from the 
trees and shrubs along the highway where said real estate abuts thereon, such trees 
and shrubs shall be exempt from the provisions of this act. 
Section 2. This act shall take effect in any city when accepted by the city coun- 
cil, and in any town when accepted at a legal town meeting called for that purpose. 
[Approved March 9, 1893.] 
THE INSECTS SUBJECT TO PARASITISM. 
On page 201 of the current volume is printed a paper by Mr. C. H. 
Tyler Townsend, entitled " Dipterous Parasites in their relation to 
Economic Entomology." which, although reaching the secretary of the 
Association of Economic Entomologists too late for presentation at the 
meeting, was submitted by him for publication in Insect Life, together 
with the rest of the official minutes. As a part of these minutes it was 
published in this periodical, but a somewhat serious misstatement 
occurs in the second paragraph, to which it is worth while to call atten- 
tion. Inasmuch as no general notes were published in that number, 
this statement is properly made at this time. Mr. Townsend says : 
Of the sixteen orders of insects, as evolved byBrauer and now generally accepted, 
only five are subject to parasitism. These are the Orthoptera, Hemiptera, Coleoptera, 
Lejndoptera, and Hymenoptera. * * * The Hymenoptera attack the last four, 
including their own order. The Diptera, however, furnish parasites upon all fire 
of these orders. 
We wrote to Mr. Townsend concerning this error and he replied that 
it occurred through the fact that his library had not yet followed him 
to Kingston from Las Cruces, and that he was, therefore, obliged to 
generalize from memory. He requested us, however, to make the proper 
correction. As a matter of fact, certain of the Diptera themselves, the 
^Neuroptera, theOdonata (egg state only), and the Platyptera are parasit- 
ized as well as the five orders mentioned by Mr. Townsend. Thus, the 
number of orders subject to parasitism is nearly doubled. Instances of 
the parasitism of insects of the four orders which we have added will 
occur to most entomologists. It will be noticed that Mr. Townsend also 
excludes the Orthoptera from the Hymenopterous parasitism, whereas 
the well known occurrence of Eupelmus in the eggs of katydids and of
