The above synonymy appears from a remarkably variable 

 series bred from larvae by Mr. H. W. B. Moore in British 

 Guiana. 



Phoenicoprocta lydia Druce. 



Dycladia lydia Druce, Ann. Mag. Nat. Hist., (6), iv, 84, 1889. S- 



Dycladia thera Druce, Ann. Mag. Nat. Hist., (6), iv, 85, 1889. e

I have no doubt of the correctness of this synonymy, judg- 

 ing from analogy with P. vacillans, quoted above. 



Family SATURNIID^ 



Hylesia euphemia Dyar. 



Mr. W. Gugelmann reports that the larvae of this species 

 live in colonies in a common nest, but that they separate before 

 spinning, forming their cocoons separately in angles of 

 branches, among leaves, etc. He finds them on Psidium pomi- 

 ferum. 



Hylesia coinopus Dyar. 



Mr. Gugelmann finds this species in colonies of 40 to 50, 

 and they all form their cocoons within the communal nest. 

 Also on Psidiutn.
