1. Further notes on the mimics of Parclopsis. E. B. P. 



It is probable that the Geometrid moth is a secondary 

 Mullerian mimic of this specially protected Lycaenid. 

 Mr. Guy A. K. Marshall captured the same species at 

 Malvern, Natal, flying with another distasteful Acrgeiform 

 Lycaenid — ALvna amaztnola* Boisd. Four examples of 

 the moth and three of the Al/u/ia taken by Mr. Marshall, 

 September 26, 1897, are now in the bionomic collection 

 of the Hope Department. These specimens of the moth 

 are much paler in tint, and possess far darker veins than 

 the individuals from Taveta, of which a second was taken 

 by Rev. St. Aubyn Rogers on December 26, 1905. These 

 local differences in the moth correspond to obvious points 

 of distinction between the Aliena and the Pcntila, thus 

 suggesting the conclusion that the two Lycmnidm act as 

 models. A much larger number of specimens from both 

 localities must however be examined and compared before 

 this conclusion can be regarded as established. 



There is no doubt that botli these Lycsenids are mimics 

 of the Acrminc's — tlie Pentila of Pardopsis, the Alfena, of a 

 general type of Acrseine colouring — thus supporting the 

 opinion that the resemblance of the moth is a case of 

 secondary mimicry. I found that both Ali&na amazoula 

 and Pentila amenaida had been placed among the Acraeas 

 of the Hope Department by the late Professor Westwood. 

 Unnamed and evidently unstudied they liad been placed 

 where almost any naturalist unfamiliar with their section 

 of the LycmnidiB would have placed them if he had not 

 the time to make a careful examination. E. B. P.
