^RT. 11 NOTES ON THE MELITAEID BUTTERFLY — CLAEK 17 



On May 31 three dead caterpillars were found on dead cat-tail 

 leaves surrounded by the cocoons of Apanteles euphydryadis. All of 

 the cocoons were empty, the parasites having emerged. 



On June 15 a number of Apanteles larvae emerged from a cater- 

 pillar which had been collected on May 31, and between June 22 and 

 25 larvae in greater or lesser numbers emerged from 15 more cater- 

 pillars which had been collected on June 13 and 20. The emergence 

 continued; by June 30 larvae had emerged from 12 more, and by 

 July 18 from 18 additional, making a total of 46 caterpillars out of 

 about 250, about 18 per cent, victims of this parasite. 



On June 30 a small tachinid pupa was found in one of the boxes 

 by the side of a caterpillar from which evidently it had just emerged. 

 Mr, Charles T. Greene very kindly identified this for us as TacMna 

 raella. 



About the middle of July another tachinid larva emerged from a 

 caterpillar. Through the kindness of Dr. John M. Aldrich we are 

 able to 'sav that this was Phorocera clari'pennis.
