1The recent work on the genus Dendroctonus by Dr A. D. Hopkins, entitled The Genus 
Dendroctonus, and published by the Bureau of Entomology of the United States Depart - 
ment of Agriculture, as Technical series no. 17, part 1, has been received too late to be 
inserted in this list. \ ie. 
The treatise referred to discusses the structure of these beetles in detail, giving a long 
sefies of very fine plates. Besides describing a number of new species and putting the synon- 
ymy of the various names in final shape, many new food plants are given, and the distri- 
bution of the various species is more exactly defined. Excellent figures of the various 
species are given. é : 
The following new species are described from America north of Mexico: barberi Hopk, 
convexifrons, Hopk., arizonicus Hopk., jeffreyi Hopk., pseudotsugae 
Hopk., engelmanni Hopk., borealis Hopk., murrayana Hopk.
