from a specimen taken in a colony of Polyergus rufescens in 

 Bayern, and as we have seen Wasmann took specimens with 

 F. rufibarbis at Luxemburg. It is probable that the slaves 

 in the Polyergus colony were rufibarbis. On July 4, 1914, I 

 took a Platyphora in a rufibarbis nest at Weybridge, which 

 is probably the ^ oi A. dohrni which will now become 

 Platyphora dohrni. 



When investigating the nests of Formica picea in Matley 

 Bog in July I noticed a number of small Dipterous pupae 

 which I collected and brought home, introducing them into 

 my nest of F. picea (which I had obtained in June in the same 

 locality and had fixed up a very large glass bowl with a large 

 block of growing sphagnum) with more picea queens, workers 

 and brood. On July 14 I captured an Aenigmatias in this 

 nest and a day or two before I had observed a Platyphora. 

 This made me think of isolating some of the Dipterous pupae 

 in a small plaster cell. From these I bred both Platyphora 

 and Aenigmatias, as well as further specimens in the nest 

 itself. This seems to me to prove that they are the (J and ? 

 of the same species. 



Mr. J. E. Collin called attention to the great impor- 

 tance of this piece of work and warmly congratulated Mr. 

 Donisthorpe on the industry and patience which had accom- 

 plished it. 



Mr. DoNiSTHOEPE also exhibited photographs of the nest of 

 F. picea.
