breeding of the insect from hickory twigs {loc. cit). The color of 

 these differed from the ordinary forms. Mr. Scharwz pronounces 

 these examples not r-iigulosus, but probably an undescribed species, to 

 which he has given provisionally, the MS. name of S. icorice. 



Preventive Measures. 

 No way is known by which a tree once attacked in force by this 

 insect, can be saved. The female lays a large number of eggs in its 

 burrow under the bark, and there are probably two broods a year. 

 The best means of diminishing its numbers and preventing its spread 

 is to take up and burn the infested trees. Where there is danger of 

 attack from the existence of the insect in the vicinity, it may, perhaps, 

 be prevented by applying to the trunk and principal branches of the 

 trees, the wash of carbolic acid and soap which is frequently used, 

 with beneficial results, as a preventive of the apple-tree borer, Saperda 

 Candida, and the lepidopterous peach-tree borer, ^geria exitiosa ; or, 

 as may be still better, the carbolic wash prepared as stated in my 2d 

 Eeport, p. 24. For directions for preparing the first-named wash, see 

 page 26 of same Report.

Examples of this insect were communicated to me, by Prof. D. S. 

 Martin, of New York city, under date of August eleventh, which had 

 been taken feeding, in their larval, pupal, and perfect stages, on the 

 leaves of the button-wood, or sycamore, Platanus occidentalis. 



It is quite a common species which has broad distribution over the 

 United States. It was first described by Say in his " Descriptions of 

 New Species of Heteropterous Hemiptera of North America," printed 

 (or in part) in 1831. His description is as follows: 



Say's Description of the Species. 

 Whitish, reticulate with nervures on which are short spines; widely 

 f margined; color whitish; thorax with an inflated carina before, extend- 

 king over the head; sides dilated, bullate, a little elevated, lateral and
