Colaspis brunnea, Fab. 
[Plate VIII, Fig. 4; 1X, Fig. 3 and 4.1 
LITERATURE. 
This species was first described by Fabricius, in 1788, and one of 
its several varieties was described by Say in 1824, under the name 
of Eumolpus slavidus,* under which species name it has most gen- 
erally been treated by economic entomologists. Owing to its depre- 
dations upon the grape, it has received from Prof. Riley the ver- 
nacular name, the “Grape-vine Colaspis.” 
Its injuries to vegetation were first referred to by Townend Glover, 
who, in the Report of the United States Department of Agriculture 
for 1865, page 91, remarks (doubtless referring to this species :) 
“This year I had a Colaspis very similar to the Colaspis strigosa, 
brought to me in Washington, and said to be very injurious to the 
foliage of the grape-vine, in which the perfect insects eat innumerable 
small holes.” ‘lhe same fact was brought to the knowledge of Dr. 
Fitch in 1866, and in the “Country Gentleman” of August 30, for 
that year, he gives a brief account of it in answer to a correspon- 
dent who wrote that it was destroying his grape-vines, en masse. In. 
the second volume of the “Practical Entomologist,’ page 68, Mr. 
Walsh, in the following year, reports its occurrence, likewise, in 
Ohio and Illinois, where he found it injurious to the terminal shoots 
and young leaves of the grape. 
In the Third Report of the State Entomologist of Missouri, for 
1871, Prof. Riley treats this species as a grape-leaf pest, figures and 
describes the beetle and the larva, and notes also the fact that the 
latter devours the roots of strawberries. His description of the larva 
was drawn from two poor alcoholic specimens; but on page 34 of 
his report for the following year, having received in the meantime 
numerous examples from strawberry fields in Southern Illinois, he 
revises the description, giving additional figures of the head and 
mouth parts, and of a ventral segment. There is some reason to 
believe, however, that this second description really relates to a 
different species from the first, being probably one of the two other 
forms of the root-worms to be discussed hereafter. 
In the third volume of the American Entomologist for 1880, Riley 
reiterates the statements of his third report, and likewise reprints the 
figure of the larva there published. 
Subsequent mention of the species in the thirteenth Report of the 
Ontario Entomological Society, in the Transactions of the Illinois 
State Horticultural Society for 1881, in a work on Insects Injurious 
to Fruits by Mr. Saunders, and in the Transactions of the Miss- 
issippi Valley Horticultural Society for 1882, add nothing to our 
knowledge of this insect or its life history. .
