Leptura subhamata Rand. 



A rather slender, somewhat triangular beetle with a subtriangular spot near llie 

 middle of the outer margin of each wing cover, occurs on hemloi k. 



This beautiful insect may be easily recoo^nized by its yellowish elytra 

 with a subtrianoiilar spot near the middle oi the outer margin. It was 

 taken on tamarack at Lake Clear Junction July S, 1903. 

 The trees had been killed by a fire, and this species was 

 evidently about to oviposit on tlutm. This beetle has 

 been taken by Mr Marrinijton on oak and also from 

 a beech log. 



This form was describeil from the White mountains, 

 and has been recorded from New J(!rse\-, by 1 )r Smith, 

 on the authority of Mr Leng. It is also lisictl by Mr 

 Ulke, from the District of Cohmibia, and six e.\ami)les 

 were taken b\- I)r John Hamilton, in southwestern 

 Pennsvlvania. Ihis, in connection \\\u\ its occurrence h;imai.i, d.iiirsid 

 in Xew York Statt', leads us to believe that it is some- 

 what generally ilistributed in the northeastern United States and probably 



ranees into Canada. 



Cedar tree borer 



Hylotrtcpcs lignciis I'abr. 

 .\ brownish beetle from -'» to nearly >< inch long, with two large, blue patches at the 

 base of the wing, bores in the larval stage in cedar. 



This species is common in northwestern Maine, according to Dr 

 Hopkins, who states that its slender, whitish bark and woodboring grub 

 excavates winding burrows in the l)ark ami surface of the wood of li\ ing 

 arbor-vitae, causing the death of trees and serious defects in the wood. 

 Mr b'all states that this sjiecies is common in soutlurn California, where it 

 depredates on pine, and that a nearly black variety occurs only on fir wood 

 piles situated in more or less shady forests. He states that the typical form 

 of this species may be taken on pine and spruce wood piles in sunny
