MEETINGS OF THE ENTOMOLOGICAL BRANCH. 



Meeting No. 6 held at Mr. Baldwin's house, 21st March, 

 1907 ; present Messrs Fletcher, Harrington, Halkett, Young, 

 Gibson, Metcalfe, W. H. Baldwin and J. W. Baldwin. 



Mr. Gibson showed an inflate of the larvaof Sphinx eremitus 

 which had been found feeding on Monarda, also one of Sphinx 

 kahnicB covered with the conspicuous white cocoons of an Apan- 

 teles. A specimen of the larva of Parorgyia clintonii, destroyed 

 by an Apanteles the larvae of which on emerging from their host 

 spin a mass of silk like a tuft of cotton wool, and an inflate of 

 a white grub were also shown. 



Mr. Young exhibited a large case showing life-histories of 

 Papaipeina pupurifascia, Papaipema harrisii, var., Papaipema 

 thalictri, Papaipema cataphracta, Parorgyia clintonii. Tinea gra- 

 nella, Peridroma occulta and Caripeta divisata. These were 

 much admired by those present. 



Mr. Halkett showed two butterflies which he had collected 

 in Europe in 1900, one Vanessa atalanta, at Paris, France, and 

 the other Parnassius apolla, taken in Switzerland. 



Dr. Fletcher exhibited a case of dragon flies which had 

 been determined by Dr. E. M. Walker, of Toronto. Among 

 these were some interesting local species which had not pre- 

 viously been recorded from the Ottawa district. Gomphus adel- 

 phns idi\^en dit Hull, P. Q., new to Canada; Gomphus brevis: 

 Basiaeschna Janata and Helocordulia lihleri were the species of 

 most interest. Dr. Fletcher also showed the 2nd Volume of 

 Dr. Felt's new work on "Insects Affecting Park and Woodland 

 Trees. This was much admired. 



Mr. Metcalfe spoke of the parasite Psilomastix exesorius 

 which he had reared from the chrysalis of Papilio asterias and 

 showed specimens. An interesting discussion took place on 

 parasitic insects in general. 



I^r. Harrington showed specimens of three species of 

 Panorpa which he had taken at Ottawa. He also showed some 

 sawflies and particularly drew attention to the wide range of 

 some species. Some might be found right across the continent 

 from New Brunswick to the Pacific Coast and up into Alaska. 

 'He stated that his own collection had been rearranged and that 

 he* would now be glad to assist any of the members who cared 

 to take up this interesting branch of study. He advised that as 

 manv as possible of the larvae should be collected in spring as 

 in that wav it was much easier to get good specimens than to 

 carrv the larvae over the winter, many of the species being 

 double brooded.
