17. These names are published herewith for the information of all 
persons interested. They will be forwarded by July Ist, 1912, to the 
International Commission on Zoological Nomenclature, the Commis- 
sion on Nomenclature of the International Entomological Congress, 
and to several Entomological Committees and Societies. 
18. A vote will be called on these names at the next meeting of the 
International Commission on Zoological Nomenclature, in the summer 
of 1913, and any objection to the proposed action should be filed with 
the undersigned, and stating ground for the objection, not later than 
May I, 1913.

Nomenclature, Hygienic Laboratory, Washington, D. C. 
A New Name In OrtHoptera.—Mr. A. N. Caudell has called to our 
attention the fact that the name Ceratites, proposed by us for a sub- 
genus of walkingsticks (Proc. Acad. Nat. Sci., Phila., 1909, p. 126), 
is preoccupied. We find Ceratites proposed by de Haan (Monogr. Am- 
monit. et Goniatit., p. 156, 1825), in Mollusca. To replace the pre- 
occupied name we propose Rhabdoceratites ( paBdos a rod, Keparirys 
one that has horns).—JAMeEs A. G. REHN and Morcan HEBARD. 
AN ENToMOLOGICAL EXCHANGE.—According to the European style 
some entomologists of Massachusetts have opened an “Entomological 
Exchange.” This method, now in use for more than 25 years in Europe, 
has proven to be very satisfactory and we have the sincere hope that 
such an “Exchange” in America will bring in closer touch the col- 
lectors and entomologists of both hemispheres. While I am the curator 
of the “Exchange,” Mr. Rudolph C. B. Bartsch is the secretary. I shall 
send you later the regulations of the “Exchange.”—WiLLIAM REIFF, 
Entomologist of the Massachusetts Gypsy Moth Com., 67 Hampstead 
Road, Forest Hills, Mass. 
[An announcement of this project will be found in the Exchange 
column at the back of this number.—Eb.] 
HrerMAN H. Breune, Assistant to the late Professor John B. Smith, 
has been appointed Acting Executive Officer in charge of the Mosquito 
Extermination Work at the New Jersey Agricultural Experiment Sta- 
tion, New Brunswick, New Jersey. 
TypES OF XIPHIDIUM SPARTINAE AND NIGROPLEUROIDES (ORTHOP.).— 
Following a suggestion made to me by Mr. Rehn, I have selected as 
types of the two species of Xiphidium described by me in the March 
number of this journal (Vol. XXIII, p. 111, seq.), a female of each 
species from Ocean View, Cape May County, N. J., taken in August, 
1911, and have donated them to the collection of the Academy of Nat- 
ural Sciences of Philadelphia—Henry Fox, Collegeville, Pa.
