In presenting the distribution and hosts of the various species, the author 

 has obtained the data from publications, from the examination of a number 

 of the finest public and private collections in this country, from correspond- 

 ence and from personal collecting and rearing of species. Where species 

 have been reported far out of their regular range, special inquiry has been 

 made regarding the authenticity and in presenting the data, the authority is 

 given in order that other w^orkers may be able to establish the status of the 

 case for themselves. Some rather disconcerting information in regard to 

 distribution has appeared in the search, such as Chalcophora angulicollis 

 from Ontario (14) ; Bnprestis confluens from Florida (9) and Dicereo lurida 

 from Oregon (C). Yet there seems to be no doubt regarding the identity of 

 the specimens and the capture seems to be founded on good authority, so the 

 records are included. 



It cannot be hoped that the present paper is without omission or error 

 and the author will appreciate receiving any additional data regarding hosts, 

 unusual distribution, omissions or eripor in regard to the literature. The 

 work has been brought up to January, 1925, and the more important papers 

 of 1925 have been included.
