One-third of the food of Hippo- damia convergens (5 specimens examined) consisted of equal parts of Chinch Bugs and Plant-lice. In 4 specimens of Hippodamia gJaciaUs 8 per cent, of the food was found to be Chinch Bugs, 18 per cent. Plant- lice, aud the rest vegetation. A single specimen of Coccinella Qnotata had eaten no insect food. Three specimens of Cycloneda sanguinea had eaten some Plant-lice, but no Chinch Bugs. From these observations Professor Forbes concludes that it is possible that the Ladybirds were attracted "rather by the stores of fungi in the field than by the Chinch Bugs and ; The Weeping Lace-winged Fly {Chrysopaplorabunda, Fitch) described originally by Dr. Shimer as Ghr. lllinoiensis, has been found by Dr. Shimer to destroy the Chinch Bug. Professor Eiley records the fact that the Insidious Flower Bug [Triphleps iiisidiosus, Say., Fig. 0), an insect [Fig. 6.] [Fig. Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United States.
