REVISION OF THE THROSCIDAE OF NORTH AMERICA 
(COLEOPTERA) 
[In offering the following treatment of our species of Throscidae, 
a few words should be said by way of introduction. The manu- 
script was written by Mr. Blanchard some ten years ago, but 
was never quite finished, there being certain obscure or doubtful 
points concerning which he hoped to obtain further information. 
The desired light, however, was not forthcoming, the borrowed 
material was returned, other interests supervened and the man- 
uscript was laid aside, and apparently received little if any fur- 
ther attention. On my next visit to New England after Mr. 
Blanchard’s death in November, 1912, this manuscript together 
with all his other miscellaneous entomological notes were, in 
accordance with his own request, turned over to me. Although 
essentially completed, in that the characterizations of the genera, 
tables of species and specific descriptions had been written, still 
no final draft had been prepared for the printer, and considerable 
labor has been required in arranging, correcting, copying, etc., 
etc. This work has been cheerfully if somewhat tardily done, 
in order that the time and effort expended by its author shall 
not have been wasted, and that one more paper may be added to 
the altogether too few which we have from one whom I have no 
hesitation in pronouncing one of the keenest, if not the keenest, 
and most competent of all the students of our Coleoptera.
