The resignations of Mr. J. R. Bueno and Mr. Chas. Myers were read and ac- 

 cepted with regrets. 



Professor Wheeler spoke on "Pink Insects as Mutations." He said that a 

 specimen of a pink katydid bad been sent to the Museum in the fall. It was a 

 female and discharged a mass of eggs. He formerly bad taken a number of these at 

 Woods Hole, Mass. In literature there are about twenty records of these insects, but 

 the only male known was that taken by Mr. Scudder. Pink insects were also found 

 in other orders and occurred both in green and brown forms. Scudder considered 

 these pink forms as sports. An attempt should be made to breed these forms to de- 

 termine constancy of color. He exhibited a number of pink Orthoptera and 

 Hemiptera. 



Mr. Joutel asked if these variations were produced by climatic variations, as he 

 had found pink sphinx larvae on grape in fall when leaves were turning. Dr. Wheeler 

 stated that he had taken them early in season as had also Mr. Davis and that the pink 

 variation was due to difference in pigmentation. 



Mr. Joutel spoke of the experimental work he had been doing in crossing 

 promethea 9 rnoth with cynthia $ , and from these had obtained fertilized eggs from 

 which he had secured a distinct type of larva and cocoon which he exhibited. 



Mr. Joutel also exhibited a box showing all of the North American forms of the 

 genus Strategtis, as well as some Cuban and Mexican species, and a Passalus from 

 California which was evidently new to the fauna of the United States. Strategus 

 monnon from California was one of the insects exhibited and Mr. Scbaeffer spoke of 

 this as being very rare. 



Mr. SchaeiTer gave " Some Notes on Bruchidse." While collecting in Texas 

 and Arizona he had taken several new species. Many were found on oak and on 

 account of the kinds of plants many of the species were collected on, he thought 

 that some of them must breed in something besides seeds. He then spoke of several 

 of the species and the characters used in separating them. Dr. Horn had based his 

 studies on the denticles, but did not mention the variations that occurred. He 

 had found much variation in these structures as well as in the pygidium. Dr. Sharp 

 had based his studies on the form of the insect, but in this also Mr. Schaeffer saidhe 

 had found considerable variation, so that a long series of these insects was necessary 

 in studying them. 



Mr. Leng asked what characters had been found outside of the denticles. Mr. 

 Scbaeffer said good characters could be found in the antennae but these differed 

 much in the sexes and so were difficult to use in separating the species.
