yellowish markings on the brownish wing covers, while the latter has a 

 black head and thorax and uniform gray wing covers. 



Distribution. This species has been recorded from Canada south to 

 Louisiana and as far west as Nebraska. It is probably generally distrib- 

 uted in the northern United States, at least. 



Remedial measures. As in the case of other borers, it is manifestly 

 impossible to do much e.xcept for the more valuable trees. The attack may 

 be prevented to a large extent by keeping the trees in thrifty condition, as 

 this insect exhibits a marked preference for unhealthy or diseased tissues. 

 Digging out the borers may possibly be of some value.

Red-edged saperda

This species is about the same size as the common elm borer, S. tridentata Oliv., 

 and like it occurs in the elm. Its principal food plant is hickory, it being partial to injuries 

 near the roots and infests the base of sprouts on recently cleared lands. 



The beetles occur in June in northern localities, and like most Saperdas 

 feed on the bark and stems of leaves at the ends of shoots. We have 

 bred this species from hickory stems in which the larvae lived at the junc- 

 ture of dead and living bark. They have also been recorded as inhabiting 

 the base of dead shoots. Dr Packard states that he has reared this species 

 from alder, but this habit seems to be exceptional. It rarely causes serious 

 injur)'. 



Description. The adult is a black beetle with the -wing covers, thorax 

 and head margined by a broad red line and a central one along the suture. 



Distribution. This species ranges from Canada southward to Pennsyl- 

 vania and westward to Nebraska. It appears to be widely distributed in 

 the northeastern United States.
