p. pavidus Lep. — Poyntzpass, Portnoo, May, June. On August 5, 19 17, I 

 took larvae of this sawfly on Salix ; these duly pupated, and on May 

 6, 1918, two females emerged, and others followed at intervals, but 

 no males. They were very sluggish at first after emergence, and 

 indeed continued so, except when there was bright sunshine ; then 

 they crawled about and took short flights. Their flight was very feeble, 

 and when crawling, unless they had a good hold, they fell ; they often 

 sat for a long time in one place, either on a leaf or on the earth, at 

 the bottom of the bell-glass in which they were. 



I watched carefully, but could not detect them in the act of ovi- 

 positing ; but they did oviposit, for on May 20 young larvae made 

 their appearance. This was clearly a case of parthenogenesis, and I 

 was curious to see if Cameron's statement'- that males were the result 

 would be confirmed. To my delight, on June 29th males did emerge, 

 proving the accuracy of Cameron's observations.
