the best method of preserving Tipulidae, although great care must 

 be taken in handling them, because of their fragility. He did 

 not prefer alcoholic specimens except for dissection. 



The preservation of the color of insects by alcohol and formalin 

 was discussed by Messrs. Smith, Skinner, Johnson, Castle and 

 Gerhard, the speakers agreeing that alcohol is the better of 

 the two for this purpose. 



Dr. Skinner reported the capture of Argynnis atlantis at North 

 Mt., Pa. It had not before been recorded south of Catskills, 

 N. Y. 



He also referred to the abundance of Callidryas eubule at 

 Cape May, N. J., in spite of the absence of the supposed food 

 plant of the insect from the region thereabouts. He had found 

 on investigation that it feeds also on Cassia niditans. It has 

 been asserted that it hibernates in the chrysalis, but this seems 

 doubtful, as he had seen the species ovipositing very late in the 

 season, so that it could hardly reach the chrysalis stage by cold 

 weather. He suggested the possibility of hibernation in the 

 larval stage. 



Prof. Smith referred to a previous communication on Angoch- 

 lova humeralis. The burrow was described. Nests of broad 

 cells lined with clay and surrounded by an air-chamber are put 

 off at various places along the vertical burrow which may pro- 

 ceed for several feet. The clusters of cells number from r to n. 

 The bees emerge about the middle of July and commence imme- 

 diately to burrow, making a burrow entirely different from their 

 parents in that instead of brood-cells they sent off from i to 3 

 short burrows or "fingers" along the vertical section. The 

 bees are single brooded. Adult bees had been found in the 

 burrows in September preparatory to hibernation. All burrows 

 found from May to July have brood- cells, but those built after 

 July have not brood-cells, which shows, in the speaker's opinion, 

 that the later burrow is made for hibernation only. The bright 

 metallic color of the insect was commented on as being unusual 

 for a species which spends the greater part of its life under- 

 ground. 



The speaker announced the coming issue of a new edition 

 of the List of Insects for New Jersey and asked for cooperation 

 in its preparation from the members of the social.
