NOTE ON THE OCCURRENCE OF A RARE CAPSID, 



NEAR WASHINGTON, D. C. 

 BY OTTO HEIDEMANN. 



During the past summer I have been fortunate enough to 

 discover in the vicinity of Washington quite a number of new 

 or rare Capsidcz, of which Cylapus tenuicornis Say is by no 

 means the least interesting species. The general appearance 

 of this remarkable Capsid is admirably characterized in the 

 original description of Thomas Say (LeConte edition, I, p. 377)

 Prof. Uhler's cabinet) since the days of Say, whose specimens 

 came from Indiana, I think that a few words regarding its 

 mode of occurrence will not be out of place. 



In the earlier part of August Mr. Schwarz and myself, while 

 on an excursion near Bladensburg, Md., in a very moist and 

 shady part of the woods along the Eastern Branch, came

 by a storm a year or so ago. From the upper part of the tree 

 two or three specimens of the Cylapus were beaten, but we 

 discovered afterward that the part of the tree close to the 

 ground was literally swarming with these insects. Their color 

 perfectly harmonizes with that of the bark, and they can hardly 

 be distinguished as long as they are quiet. When disturbed 

 they run with the greatest agility along the bark and take
