be discovered at this time. New leaves were developing and few yet con- 

 tained any water. Such of these as were examined contained no insect 

 life and only here and there one had trapped insects ; none had begun to 

 digest or assimilate the animal food. 



An open swamp at the head of a cranberry bog had most of the leaves 

 with pupal shells only, but though there must have been hundreds of 

 adults about, not one could be found flying, nor could we stir them up. 

 In a deep, cold, huckleberry swamp, only larvae were found. It was fair 

 to conclude from the three days' tramp that no summer brood of larvae 

 had yet begun, and it seemed strongly indicated that the insects would 

 not bite, even if given the opportunity. In confirmation it may be said 

 that late in the summer Mr. Brakeley saw specimens flying, and though 

 there must have been thousands of others round about, none made any 

 effort to disturb him. 



July 3, the leaves contained half and full grown larvae, but neither 

 pupae nor very small larvae. July 13, old and new leaves contained very 

 small larvae, evidently of recent date, while the old leaves had also 

 grown larvae and pupae. There was, therefore, a new series of larvae 

 and probably the first summer brood. July 23, the older leaves had very 

 few larvae, but almost as many very small as large ones. The new leaves 

 had all stages, from very small larvae to pupae. The indications were, 

 therefore, that the first summer brood was coming to maturity, develop- 

 ing in from fifteen to twenty days, while there were yet adult individuals 

 from the winter larvae that were ovipositing. From the small number of 

 young larvae in individual leaves, the indications were that eggs were 

 laid either singly or in small groups. 



The next sending did not come until August 21, and then there was 

 everything from the most minute larva to pupa just ready to trans- 

 form. So small were some of the larvae that I hunted for eggs or egg 

 shells, but failed to recognize any. It is probable that the youngest lar- 

 vae represented a third brood, but breeding was practically continuous, 

 all stages being found at any time after the middle of July. 



September 1, the same conditions existed and there was a large num- 

 ber of larvae so small that it seemed as if at least egg sliells must yet 

 remain, but none were found. Fortunately Mr. Brakeley returned to 

 Lahaway early in this month and on the thirteenth — lucky day! — he 

 found the eggs floating on the surface of the water in the pitcher plants. 



September 14, I had an opportunity to spend a couple of hours in a 

 swamp in the pines near Hanover Station, Burlington County, and 

 found the pitcher plants there full of the Wyeomyia in all stages from 

 babes to pupae. I collected the entire contents of tlic pitchers in alcohol,
