132 SECOND REPORT OF THE STATE ENTOMOLOGIST. 



twig borer, Amphicerus hicaudatus. Mr. Cooke says that the Folycaon 

 is quite injurious to apple and pear trees, and also to the grapevine. 

 Thus, from what we know of its natural history, we may safely infer that 

 its habits do not differ essentially from those of A. bicaudatus, i. e., the 

 beetle bores for feeding purposes in living twigs of fruit-trees and grape- 

 vines, never, however, ovipositing in such twigs, and both male and 

 female being concerned in this destructive work. Both species live, in 

 all probability, as larvae in the dead and dry wood of forest-trees 

 [C. V. Riley.] 



In consideration of the above species, Polycaon confertus, being so 

 nearly allied in classification with Amphicerus, it is interesting to find 

 this close conformity in habits. They are members of the same sub- 

 family of the Piinidm, viz., Bostrichince. While the latter, in the recent 

 arrangement of Drs. Leconte and Horn, pertains to Tribe ii {Bosiri- 

 cTiincB), Polycaon has place in Tribe iii {Psomi), while Lyctus, associ- 

 ated with Amphicei'us in grapevines, follows immediately after in the 

 subfamily of Lyctinm. 



It is always gratifying to the economic entomologist to discover 

 identical habits among the different members of a family, as above men- 

 tioned, as it gives the promise and almost the assurance that measures 

 which may be found effectual in controlling one of the species will be 

 equally serviceable against the others.
