the dull uniformity of others, but the same feature is seen in the 

 European specimens. Some specimens from the south of Europe 

 exhibit a yellowish tint at the base of the hemelytra. 



In Maryland they live beneath the loose bark of decaying trees, 

 such as oak and liriodendron, but most likely are not confined to 

 those kinds of trees. Specimens from beneath bark where the de- 

 bris is wet and plastic are more robust, plethoric and darkly colored 

 than others which I have found in drier spots. Recently, I have seen 

 them running over the fruit of the raspberry.

The species is common in Massachusetts, and often swarms in mid- 

 summer on the flowers of Leucantliemwn vulgare. During Septem- 

 ber and October they may be beaten from trees and shrubs. It 

 extends over all the eastern United States and into Canada.

This disgusting insect is widely distributed over Europe and most, 

 if not all, of temperate North America. Forms from India and 

 Africa differ from this and are probably distinct species. From the 

 differences in the shape and size of the rudiments of hemelytra, it 

 might be safely inferred that some specimens become almost, if not 

 quite, fully winged. Specimens from the negro-quarters of the East- 

 ern Shore of Maryland are often twice the ordinary size and covered 

 with almost erect bristly hairs. A new species has recently occurred 

 to me near Baltimore, which I took from a white oak tree.
