NOTES ON HETEROCERUS. 
By Gro. H. Hor, M. D. 
While attempting to bring order in an overcrowded box in my 
cabinet, the specimens of He/erocerus had to be removed and their re- 
placement elsewhere has cost me some little trouble in an attempt to 
assort the specimens specifically. While I have not yet been able to 
satisfy myself as to the validity of some of Kiesenwetter’s species, certain 
points of some interest have been developed. 
H. pusillus Say, “mdatus Kies., /uteolus Lec. This species is re- 
markable in that the <j has at the base of the mandibles a lobe which 
overlaps the labrum, nearly meeting. This is our smallest species and 
is very widely distributed. Dr. Hamilton takes it at Allegheny, Pa., 
and I have it from Kansas, Texas, Arizona, Southern California and 
Mexico. 
H. pallidus Say. This is the large pale species taken rather 
abundantly by Prof. Snow in Kansas and N. Mex., extending also to 
‘Arizona and Texas. 
Three species have been observed in which the labrum, ,j\, is more 
or less produced at middle—/aératus, ventralis and pallidus. 
It is my hope to make it possible to determine our species, but the 
difficulty of obtaining specimens from the region east of the Mississippi 
is a great draw-back. No one seems to have collected them, and one 
or two specimens by themselves are of little use. 
From the western regions (Cal., Ariz., Tex.,) there is an abund- 
ance of material. If those who can collect them will take as many as 
possible and thereby assist in the work I have in hand, all will be 
benefited. 
Book Notices. 
Bulletin No. 1, of the Office of Experiment Stations, U. S. Depart- 
ment of Agriculture is at hand, and contains the organization of the 
various stations and matter of interest necessarily to entomologists. In 
a late number of Entomologica Americana there was published a list of 
the entomologists of the experiment stations which is rather incomplete 
and not quite accurate. The receipt of this bulletin makes a more 
complete list possible.
