Dr. Dean explained, with black-board drawings, the remarka- 

 ble points of Mr. Riederer's serial sections of the Brook Trout. 



Mr. Dudley explained, with black-board drawings, the method 

 of growth and repair of the beaks and mandibles of Calotermes 

 milesnasitermes, and also read a communication from Mr. J. 

 Beaumont, of Colon, S. A., a Corresponding Member of the 

 Society, on the swarming of the Termites of that locality. 

 • Mr. Zabriskie said of his exhibit : These are specimens of 

 our only native species of Termite, and they are all taken from 

 one colony, found, on the loth of the present month, in a piece 

 of White Pine plank lying on the ground, at the Water Works, 

 Flatbush, Long Island. The region is so frequented by ento- 

 mologists that nearly every available piece of wood lying upon 

 the ground is turned, about once in every twenty-four hours, in 

 search of prey. But this piece of plank happened to be con- 

 cealed in a clump of shrubbery, and had probably lain undis- 

 turbed for a long time. The colony was strong in numbers, and 

 the tunnels and cells excavated in the wood were unusually 

 large. One of the cells here exhibited measures ^^ X i inch 

 in diameter, and three inches in length. 



Colonies are abundant in this locality in decaying stumps, 

 pieces of board, or in any other wood lying for any considera- 

 ble time upon the ground. During this present season the first 

 observed males and females with wing-pads were found in a 

 decaying stump on April rgth. On May 7th, in another stump 

 were found males and females further advanced, some still with 

 wing-pads, but others with thoracic and abdominal rings be- 

 coming darkened, and with full-sized wings, although the wings 

 of all were still ivory white. It will be observed that the female 

 here exhibited, taken on May loth, has the color of full develop- 

 ment — head and rings nearly black, and wings transparent with 

 dark veins. After the early days of June no winged specimens 

 were found.
