Larvae of Sitaris muralis. — Commander J. J. Walker 

 showed on behalf of Mr. A. H. Hamm, very young larvae of 

 ■Sitaris muralis, hatched at end of October and beginning of 

 November fi-om ova laid by $ $ s in captivity (the natural 

 place of deposit of these eggs being at the entrance to the 

 burrow of the bee, Anthophora pilij)es, in stone walls near 

 Oxford). Hitherto the larvse had kept together on the mass 

 of empty egg-shells. 



Pyralis lienigialis at Oxford. — Commander Walker 

 also exhibited two specimens of the rare Pyralis lienigialis, 

 Zell, ? , taken at light in his house at Summertown, August 

 1906 and 1907. 



Suggested Mimicry in Bourbon Butterflies. — Lieut.- 

 Colonel Manders exhibited the $ of Fajnlio phorhanta from 

 Bourbon, an aberrant member of the nireus group of Papilios, 

 and compared it with the other members of the same group 

 from the African mainland, Madagascar and Mauritius, kindly 

 lent for the purpose by Professor Poulton. He pointed out 



that whereas in all the other species the 5 ? s were some 

 shade of green similar to the c? c? s, the Bourbon insect was 

 more or less uniformly brown. Jle suggested that this was 

 due to mimicry, Euflo&a goudoti, a species strictly confined to 

 Bourbon, being the model. The case had been dealt with more 

 fully and the insects figured in his paper on " The butterflies 

 -of Mauritius and Bourbon," in the Transactions 1907.
