in that genus, but it is doubtful whether it may not be ne- 

 cessary to remove the Oporabia to the genus before us : the 

 antennae are similar, but the wings have not the contour and 

 texture of the type of Oporabia which those of O. muUistrigaria 

 have ; this last species has been included by the author of the 

 ' Illustrations' in the genus Larentia (Eubolia B. E. pi. 707), 

 with which it cannot be naturally associated. 



Oporabia dilutata is characterized by very ample superior, 

 and rather elongated and narrow inferior wings, and the mas- 

 culine antennae are merely ciliated. 



O. muUistrigaria has less ample but similarly formed wings, 

 with the masculine antennae bipectinated, the rays short. 



Venusia Cambrica has more compact wings, formed like 

 those of Zerynthia, but the markings bear a greater resemblance 

 to Oporabia or Lobophora (pi. 81). It is possible that the 

 discovery of the female might lead to the settling of its affini- 

 ties, but that sex is at present unknown. 



The only specimen I have seen of V. Cambrica was taken 

 at Hafod in Cardigan, near the Devil's Bridge, and was given 

 to J. C. Dale, Esq., by Mr. House, of Clifton, near Bristol. 



For beautiful specimens of Mespilus germanicus, Medlar- 

 tree, I am indebted to Mr. Luxford, who gathered them last 

 June between Reygate and Nutfield, Surrey.
