ENTOMOLOGICAL CONTRIBUTIONS. 167 



at intervals of a week, the three broods of the above species have had, 

 during the present year, a continuance of about a month each, the 

 last brood probably continuing for a few days longer. Approximate 

 periods of their duration would be, of the first brood, from May 5th 

 to June 5th ; second brood, from June 20th to July 20th ; third 

 brood, from July 28th to September 1st. 



Nisoniades Lucilius emerged after thirteen days in the chrysalis 

 state. The larva had been reared in confinement, and was transformed 

 to a chrysalis among the leaves of its food-plant. 



August 31st. Eight males of the hitherto rare Hesperia Leon- 

 ardus were collected on the summit of a hill at Center, indicating it 

 to be partial to elevated ground. Several L. comyntas of a new 

 brood were taken, and also fresh specimens of Vanessa Antiopa. 



September 9th. At Bethlehem collected several males of Niso- 

 niades Lucilius, with some of its larvae just from the egg, and others 

 half-grown. Argynnis Myrina were observed in copula. Of Hes- 

 peria Taumas, usually rare, six males and one female were collected. 



September 14th. Argynnis Idalia was taken for the first time in 

 the vicinity of Albany. Young larvae of L. misippus and N. Luci- 

 lius were observed. Bethlehem. 



October 21st. On "the Island" collected numbers of the chrysal- 

 ides of P. rapce which were attached to the under surface of the 

 stems of the coarser weeds lying on the ground. Several were taken 

 from the lower Bide of prostrate pieces of timber. None were found 

 upon the trunks of trees or standing weeds, nor on fences, except at 

 one place where tomato vines had grown over the lower board, 

 affording a partial protection. A few larvae were found suspended, 

 and nearly ready for transformation, and a few were still remaining 

 on the plants. 



From a portion of the above collection of chrysalides placed in a 

 box, there were obtained during the winter ten male and thirteen 

 female imagines.
