They were not ill during their whole stay in Costa Rica and 

 attribute their entire freedom from fever to the healthfulness 

 of a great part of the region visited, to their always sleeping 

 under mosquito nets and, when abroad, to covering the ex- 

 posed parts of their bodies, wherever mosquitos were noticed, 

 with a mixture of citronella oil and cocoa butter (suggested 

 by Dr. Henry Skinner), an ample supply of which was taken 

 with them. Neither of them took a single grain of quinine 

 during the year. Drinking water was boiled, except when it 

 was rain water directly gathered and filtered through char- 

 coal, otherwise Apollinaris, procurable throughout the coun- 

 try, was substituted. 



Grateful acknowledgment was made of the kind aid received 

 from many friends, both Costa Rican and foreign, to whom 

 much of the success attained is due. 



Dr. D. M. Castle, who had just returned from Florida, said 

 the weather conditions there were very unfavorable for col- 

 lecting. It was very cold and the winds were high. In spite 

 of the unfavorable weather he managed to get some desirable 

 species. Savannah and Tybee Island were visited. At En- 

 terprise the weather was cold with no rain. Coronado Beach 

 was visited and also Miami and at these places the conditions 

 were very much the same. Sweep netting was not possible 

 so the umbrella was largely used. 



Mr. Rehn made a few remarks on the Acridean genus 

 Eotctti.r, illustrating the same by specimens of four of the 

 five known species. The fifth species is represented by the 

 unique type in the Hebard collection. The distribution of the 

 genus is now known to cover the coastal section of the south- 

 eastern United States from north-central Florida to southeast- 

 ern North Carolina. 



Mr. J. A. G. Rehn was elected a member and Mr. John H. 

 West an associate. 



HENRY SKINNER, Recorder. 



In a former circular your attention was drawn to the First 

 Congress of Entomology which will be held at Brussels from 

 August ist-6th of this year. We have now the pleasure of 

 presenting the Preliminary Programme and inviting you to 

 become a member of the Congress. Many governments, pub- 

 lic institutions and societies have already signified their inten- 

 tion of sending delegates, and it is to be hoped that the gath- 

 ering will be thoroughly representative of our science.
