To the excellent account of this insect given by Professor Weed we 

 have nothing to add save a few notes as to its occurrence at Saranac 

 Inn. The imago was not observed at all outside our breeding cages. 

 Larvae and pupae were obtained in several places about the shores of 

 Little Clear pond. 



June 14 Dr Felt and I, while looking over the ground preparatory to 

 beginning regular operations, rowed into the little bay on the west side of 

 Blueberry island in Little Clear pond and found the species in abundance. 

 The bank was overhung with clumps of fragrant Labrador tea, and here 

 and there lay a rotting hemlock log half in the water and half out, the 

 exposed portion bearing an ornamental covering of matted moss and 

 sundew plants. Our boat touched shore beside one of these logs; and 

 there was a hole in the rotten wood, with an empty pupa skin hanging 

 out of it. We followed this clue, and, examining the log, found the 

 Chauliodes pupae. By pulling apart the crumbling fragments with 

 our fingers, we in a very little while found in this and a few other logs 

 near by, 25 pupae. One of these transformed on the way home, and the 

 imago was lost ; three were raised ; a number were preserved for specirriens, 

 and the remainder died. On the i6th I returned to this place again, 

 and found that by this time many had transformed. There were still 

 plenty of pupae to be found, however, by diligent searching of the partly 

 submerged and crumbling logs. 



Chauliodes eggs, which I took to belong to this species, were not 

 uncommonly found attached to the flat surface of some old, gray snag or 

 board several feet above the surface of the water. They were more 

 grayish in color than the eggs of Ch. serricornis, and were ar- 

 ranged in somewhat more regular V-shaped rows, and never more than 

 one layer in depth. I saw a number of clusters about July i on the 

 side of the boathouse facing the pond. These, as well as the clusters
