THE STINK-BUG FAMILY. 91 
The genus Euschistus contains a number of species which 
are very common in our state. They are found running about 
early in spring and late in autumn, and may be found in all 
stages during the summer. The one illustrated (lig. 88) is 
Euschistus variolarius Pal. Beauv., which may be called the 
Brown Stink-bug, although it varies greatly in color, from yel- 
low to light brown. It is sometimes injurious. In one case a 
large colony of these bugs was discovered upon asparagus plants, 
sucking the sap and killing the plants; again they were found 
in large numbers upon the heads of wheat, where they did no 
good, judging from the wilted appearance of the infested plants. 
Cosmopepla carnifex Fab. is another very common insect, 
sometimes covering wild plants. It is a pretty insect, as may

be seen in the illustration, Fig. 89, measuring about three-tenths 
of an inch in length, of a shining black color, and a densely punc- 
tuated body. Red or orange colors ornament the lateral margin 
of the body, including the prothorax, basal half of the wing- 
covers, meta-thorax, and abdomen. The disk of the pronotum 
is crossed by a transverse and a longitudinal line of the same 
color, as is shown in the illustration. Two bright red or orange 
spots are found near the tip of the scutellum. Usually it is of 
no economic importance, but it has recently been found in large 
and injurious numbers upon such plants as the raspberry and 
blackberry. 
Oebalus pugnax Fab., illustrated in Fig. 90, is a friend to 
the cotton grower in the South, as it there destroys the larve of 
the cotton moth. But here it has very different habits, and it
