mentioned by Mr. William Saunders, and a good account of the 
character and amount of its injuries was given, together with a 
description of the results of some experiments made upon it with 
hellebore. This article also contains a description of the larva, and 
additional notes on its life history. 
In the transactions of the State Horticultural Society of Illinois 
for 1877, Mr. O. B. Galusha relates his discouraging experience 
with the pest in Illinois; but Prof. Riley gives the fullest account 
of the species yet published, in his last (ninth) report as State 
Entomologist of Missouri. This last article includes descriptions and 
life histories of all stages, and figures of all except the egg, together 
with notes on distribution, and injuries to the strawberry, and brief 
suggestions of remedies. 
Full summaries of previously ascertained facts were published in 
the Highth Report of this office (1878); and in the Transactions of 
the State Horticultural Society of Illinois, for the year following, 
Miss Emily A. Smith records her observations on this species in 
strawberry fields in Central Illinois, expressing a doubt of the oceur- 
rence of more than one brood, at least in this latitude. The ravages 
of the larva in New Jersey are briefly mentioned in the American 
Entomo!ogist for 1880 (p. 109); and in 1881, another general account 
of the species, with some personal observations, was given in the 
Horticultural Transactions of our State Society for 1881. In the 
first Report of Prof. Lintner, as State Entomologist of New York 
(1852), the species is merely mentioned as one of those susceptible 
to poisoning by hellebore. In the Transactions of the State Horti- 
cultural Society of Iowa for 1882, Prof. Herbert Osborn relates the — 
results of some experiments upon it with arsenical poisons, and 
Miss Alice B. Walton notes the occurrence of the species in new 
beds, early in the season, but remarks that, for some unexplained 
reason, the second brood did not appear. Finally, a compiled, 
illustrated article on this species, taken chiefly from Riley’s Ninth 
Missouri Report, was published in the Transactions of the Mississippi 
Valley Horticultural Society for 1883. 
Besides the above, the usual number of republications, more or 
less full, of the original observations of Riley, Smith, French, and 
others, have appeared in the agricultural and horticultural papers; 
in the Reports of the United States Department of Agriculture 
(1867 and 1873); in the American Naturalist (Vol. VII, p. 524); in 
the Annual Report of the United States Geological Survey (1875, 
p. (96); in a report on the Injurious Insects of Vermont, by Prof. 
G. H. Perkins; in Psyche (II, 97); and in the Tenth Report from 
this office (pp. 64, 65 and 68). 
DESCRIPTION. 
Imago. This is a four-winged insect, with the wings shaped much 
like those of a bee, but provided with a greater number of trans- 
verse veins. ‘The body is black, with an interrupted brownish band 
on either side of the abdomen. The head is transverse, finely 
punctured, widely but not deeply channeled at the sides of the 
ocelli, from the nasus to the summit. The edge of the nasus is 
moderately crenate, and a ridge extends down its middle. The
