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 ( pa/3Sos a rod, Kepartr^s 

 one that has horns). JAMES A. G. REHN and MORGAN 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.

 column at the back of this number. ED.]

TYPES OF XlPHIDIUM 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. m, 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.
