A DAY'S COLLECTING IN FEBRUARY. 



February 12th (Lincoln's Birthday), of this year, was unusually warm 

 and spring-like. The temperature rose as high as 52*^, and the clear sky 

 and little wind made it a joy to be out in the open, in the sunshine. 



I went to Staten Island that day, with the intention of working up 

 some Orthoptera with Mr. W. T. Davis, but the feel of spring in the air was 

 irresistible, and as I was anxious to secure aquatic Hemiptera as early in 

 the season as possible, we went by trolley to some woodland ponds near 

 Richmond. The fields were very wet on the way, but hopping among 

 the dry leaves were young grasshoppers, emerged from their winter's sleep. 

 Some Diptera also were hiding among them, and they were quite active 

 when disturbed. 



When we arrived at the pond, a disappointment awaited us. It was 

 nearly all frozen over ! However, we pushed through the brambles to the 

 edge, and began to fish under the thin ice. I took on this side of the 

 pond two Corixa Harrisii, active. Working our way along the side to the 

 end where the outlet was, we found the water free from ice. On the sur- 

 face, two species of Podurans were abundant, and an immature Jassid 

 was floating and jumping. We got none of these. Waiter beetles, also, 

 were swimming about. 



The sun, meantime, was melting the ice, and as we got to the 

 opposite side from where we started, quite half the pond was clear. On 

 this side, Haliplidse and Dytiscidae were more abundant, swimming freely 

 or else clinging to the stems of the bushes rising from the water, sunning 

 themselves. 



On the trunk of a white birch I saw an Aciliiis semisulcatus, about 

 six inches from the surface, on the sunny side. It was alarmed by the 

 noise I made, and dropped into the water. Contrary to what seemed to 

 be the rule, this beetle submerged itself with great ease, 



Here, also, I took a Haliplid from a bush, on which there were a
