Hylotrupes bajulus Linn. 



A black beetle about ^ inch long, with a gibbous pro thorax sparsely clothed with 

 white hairs, with shallow, confluent punctures and the elytra with downy white spots 

 forming two irregular bands, occurs on pine and spruce. 



This species appears to be rare in New York State, since we had no 

 specimens in the collection prior to receiving a few beetles in June 1904 

 from Yonkers, where it was stated that they were emerging in some num- 

 bers from Mooring, presumably spruce. Harris states that this is probably 

 an introduced species, and that it is found in this country only near the 

 seacoast. 



Pales weevil 



- 



Hy I obi us pales Herbst. 



A dark, chestnut-colored weevil 3/i inch long, occurs in May and June on pines or in 

 mill yards. 



This beetle | pi. 20, fig. 8] lives under the bark of various pines and is 

 widely distributed, ranging from Florida northward to Maine and Lake 

 Superior. It occurs somewhat commonly on hard pines at Karner from 

 June to the latter part of September. 



Life history. The life history is summarized by Dr Packard as follows : 

 The grubs make irregular galleries under white pine bark and later tra- 

 verse the sapwood, transforming in autumn in pupal cells excavated in the 

 latter. The insects protect their shelters with a thick roof of sawdust or 

 chips and sometimes as many as eight or 10 cells may be found within an 

 area of four square inches. The grubs remain till early spring in these 

 retreats, transforming to pupae in March, the beetles appearing in May or 

 June. The eggs are laid either in the sides of the old burrow or in 

 crevices of the bark. We have taken adults as late as October 23 and 

 it is probable that oviposition continues throughout the summer.
