By a resolve of the Legislature of Massachusetts, Mr. Flint was directed to issue a 
2 W edition of Dr. Harris’ admirable Treatise on Insects Injurious to Vegetation, with 
litable additions and illustrations, and was 
so authorized to use the plates prepared for 
le edition for the Commonwealth, in the 
ublication of one or more editions designed 
a* wider circulation than that for the State 
mid be expected to have. It was thought best to insert the additions contemplated 
1 the resolve, in the form of foot-notes. No alterations have been made in the author’s 
mgnage, and the additional notes are enclosed in brackets, to distinguish them 
f rom those in the former editions. Large additions have 
been made in the text, however, from the author’s own 
manuscript. These will be found exclusively in the 
chapter upon the butterflies. Professor Agassiz very 
kindly offered to supervise the drawings, comparing them 
with the original specimens before engraving. It is be¬ 
lieved that very great scientific accuracy has thus been 
secured in the illustrations. 
This work is the most popular one on entomology, 
and, indeed, almost the only one not intended for the 
.vnge .TTTTyi > Sc oo. 
Chapter VII. 
Diptera.— Gnats and Flies. Maggots and their Transformations. Gall-Gnats. Hes¬ 
sian, Wheat, and Radish Flics. Two-winged Gall-Flies, and Fruit Flies.

purely scientific student. The familiar descriptions of the insects aic much aided by 
the beautiful illustrations. The work comprises those insects which are injurious to 
cultivated and wild plants, and is sufficiently 
systematic to give a general idea of the 
BBgg——« ww classification of insects. It takes a practical 
view of the matter, as well as a scientific 
one, and gives the means, as far as known, 
of combating these enemies of the cultivator. In concluding his preface to the second 
edition of this work, Dr. Harris wrote : “ In the course of eight years, all the copies of 
the Report, and of the other impression, were entirely disposed of. Meanwhile 
some materials for a new edition were collected, and 
these have been embodied in the present work. * * * 
Believing that the aid of science tends greatly to im¬ 
prove the condition of any people engaged in agricul¬ 
ture and horticulture, and that these pursuits form the 
basis of our prosperity, and are the safeguards of our 
liberty and independence, I have felt it to be my duty, 
in treating of the subject assigned to me, to make it 
useful and acceptable to those, persons whose honor¬ 
able employment is the cultivation of (he soil. ’
