the seurfy scale, Chionaspis furfurus. I noted these facts some years 
ago in Illinois, and mention them here again, as it is generally believed 
that these species are single-brooded. 
Many species of insects found in stored grains and the manufactured 
products have been sent me from various places. The ‘flour weevil,” 
Tribolium confusum, usually found in flour mills, has been a very com- 
mon one. It is perhaps the most injurious and troublesome of the mill 
pests, on account of its wide and general distribution. 
The Mediterranean flour moth, Hphestia kuehniella, has also been a 
conspicuous mill pest. I have bred the following hymenopterous para- 
sites from material sent to me from New York, Pennsylvania, and Cali- 
fornia: Habrobracon hebetor Say, Omorga columbiana Ash., and Meso- 
stenus gracilis Cr.' Some years ago I reared the first-named parasite 
from the flour moth from California; but this is, I believe, the first 
‘Instance of the rearing of the other two from this insect. 
The bolting-cloth beetle, Tenebroides mauritanicus, has maintained 
its notorious reputation as a destroyer of bolting cloth in mills. It has 
also been reported in stored wheat, and lately (July 20) a large grocer 
of Baltimore wrote me that some insect was eating through the parch- 
ment of jars containing jams and jellies imported from Liverpool, 
England. I examined the material July 28, and found the bolting- 
cloth beetle and the saw-toothed grain beetle, Silvanus surinamensis, 
responsible for the injury. There were a hundred dozen of these jars, 
and an examination of the original packages showed clearly that the 
insects were brought here with them. Cutting through the parchment 
covers, both beetles and their young were found feeding upon the sur- 
face of the preserves. The marmalades were more seriously infested 
than plums, strawberries, etc. The entire lot was fumigated with 
bisulphide of carbon and re-covered with new caps and parchment 
paper. 
Before closing this paper on miscellaneous notes, I must mention the 
fact that the harlequin cabbage bug, Murgantia histrionica, which has 
been such a serious enemy to cabbage and allied plants for the past 
few years, has hardly been seen by us this season. Only one complaint 
of injury by it has been received at my office, and that from lower 
Charles County. Where they were by the thousands last year on the 
College farm, scarcely one can be found at the present time (Au- 
gust 1). 
The asparagus beetle, Crioceris asparagi, has also been conspicuously 
absent this season. No reports of damage to asparagus have been re- 
ceived, and I have seen very few specimens during my observation 
tours through the State. 
The cabbage plusia, Plusia brassice, ruined hundreds of acres of cab- 
bage for us last year; but hardly a specimen has been observed this 
1 These parasites were determined for me by Mr. William H. Ashmead, of the U.S. 
National Museum.
