larvae or grubs that would doubtless live through the winter. A delay till 

 the second season appears to be quite common in this species, and is one of 

 nature's safeguards against extermination should there be an entire failure 

 of the crop in any one year, as happens occasionally. This smaller species 

 is known to breed in chin(juapin nuts and acorns, as well as chestnuts while 

 the larger form has been obtained only from the latter. There Is appa- 

 rently no record of the larger species remaining in the pupa stage till the 

 second year, although it is probable that such occurs. Only one parasite, 

 Urosigalphus armatus Ashm. has been bred from this chestnut 

 weevil. 



Remedial measures. There is no practical method of preventing ovi- 

 position, unless it i)t; b\' jarring which woulil probably prove too expensi\e 

 in most cases. Ihe infested nuts should br destro\ed each year before the 

 insects forsake them and enter the ground. Wormy chestnuts may l)e 

 easil)- recognized by pouring the nuts into a vessel of water, and the lighter 

 ones will rise to the surface after a little stirring. The sound ones should 

 be dried, and it would be safer to thoroughly treat them with carbon 

 bisulfid, using at least one pound for each 1000 cubic feet of space and 

 exposing the nuts to the fumes for about 24 hours.

Ring-legged tree bug 



Broclivuicna aiunilata habr. 

 This dnrk grayish blark, rather thick trt-e hug ahoiil Ja inch hing, may lie taken 

 from midsummer to the end of the season and probably in early s|>ring, on various trees. 



There are only three examples in our collection and these were cap- 

 tured from miscellaneous trees; one, in particular, probably occurring near 

 or on pines. 



Description. This species has been frequently mentioned in literature, 

 though in some instances it has probably been confused with R. 4-p u s-
