one of the volumes of the quarto reports of the Hayden Survey — the beautiful typography 

 and illustration of which causes us to regret the prospective speedy termination of tLe 

 series. As the Tertiary Shales of the Kocky Mountain region give every promise of 

 being richer in insect remains than any other country in the world, the material for this 

 volume will be more ample than any other student in fossil entomology has been able to 

 command. 



For the evident omission of reference to much valuable work done duriug the period 

 reviewed, I ask indulgence. The time that I had allotted to the preparation of my sketch 

 was found, too late, to be quite insufficient for the extended bibliographical examinations 

 required for even an approach to completeness. I offer it only as a partial sketch, and 

 as such please accept it. 



On motion, the thanks of the Club were tendered to the President for his able and 

 interesting address, with the request that a copy be sent to the Canadian Entomologist 

 for publication. 



The Club next proceeded to consider the amendment to the Constitution proposed at 

 he St. Louis meeting, and after much discussion, the amendment was adopted in the 

 following form: — 



1st — No resolution affecting important scientific questions' shall be adopted at any 

 meeting of the Club unless there shall be present at least seven members who shall have 

 been enrolled at least one year previous to said meeting. 



2nd — "When any motion has been carried by the Club, such motion shall not be 

 rescinded at any subsequent meeting unless there shall be present at least seven 

 persons who 6hall have been enrolled as members one year or more previous to said 

 meeting. 



3rd — Five members shall constitute a quorum for the transaction of ordinary 

 business. 



The Secretary was instructed to draw up a list of members of the Club, to be em- , 

 bodied in the record of its proceedings, including all those who had been present at pre- 

 vious meetings. 



The second meeting was held at 4:30 p.m., the President in the chair. 



Mr. Grote exhibited specimens of Pseudohasis eglanterina sent him by Mr. James 

 Behrens, of San Francisco, who had collected them on the top of Mount Shasta. These 

 differed from the ordinary specimens in being almost entirely black on the upper side. 

 Mr. Grote expressed the opinion that this variation was mainly due to the climatic in- 

 fluences to which they were subjected in this elevated situation. 



Dr. J. G. Morris referred to the fact that certain Water Beetles carry with them 

 when they dive a globule of air underneath their bodies, and asked for information as to 

 what purpose it served. Mr. E. P. Austin said that this bubble was retained underneath, 

 by the stiff hairs along the abdomen, and as it was known that the air gradually disap- 

 peared if the insect remained long under water, it was supposed that the air was gradu- 

 ally inhaled by the insect, which was thus enabled to lengthen its stay under the water. 



Mr. B. P. Mann presented a list of the Entomologists of North America, and re- 

 quested the members to confer with him as to additions and corrections. Some beauti- 

 ful examples of coloured drawings of Xoctuce by Mr. Pohlman, of Buffalo, were laid upon 

 the tabie for the inspection of those present, and were much admired. 



Mr. Scudder called the attention of the members to a lepidopterous insect which 

 was doing much damage to the junes on the Island of Nantucket. Previous to the war 

 of 1812 the islaud was well wooded, but during that struggle the occupants were reduced 

 to such straits for fuel that they had burned every tree. For many years the island had 

 remained in a barren state, but some time ago plantations of Pines were begun, and a 

 broad belt of young trees of Pinus rigicla from 10 to 20 feet high, with scrub Oaks, now 

 cover a large part of the island. The success of this experiment is seriously threatened 

 by the presence of the insect referred to, which is a Tortrix belonging to the genus Re- 

 tinia, and closely allied to duplana, syhostrana and frustrana of Europe. The larva affects 

 the tip of each terminal bud and bores its way through this into the twig to the depth of 

 two or three inches, killing the terminal leaves and thus preventing the trees from mak- j
