differences in the imago, pupae, however, exposed to heat yield images of darker and 

 more intense coloring, while such exposed to a longer period of abnormal cold will 

 produce comparatively lighter effects. Excessive moisture causes a scarcity of scales 

 and gives the wings a glassy semitransparent appearance. He exhibited a number of 

 specimens produced by abnormal temperature. 



Mr. Davis spoke on the dragonflies of Staten Island. 



Mr. Beutenmuller exhibited a nest of Vespa crabro from Europe. This nest had
