" Perliaps tlie most interesting tiling about this case is 

 the correlation of the colour in the larva, cocoon and adult. 

 Pearce [Entom. XV, p. 254] also records that a <? of this 

 form bred at Portsmouth had a dark larva and cocoon. 

 Although this correlation undoubtedly exists in the above 

 cases, dark larvae do not always give rise to dark adults, and 

 dark adults may arise from normal larvae. The only other 

 case which I know in which there was a similar relation between 

 the colour of the larva and the adult was in Abraxas gros- 

 sulariata in a certain garden in Essex, where all the larvae 

 were almost black and the adults were much darker than the 

 type. This latter case may, however, have been accidental." 



Mr. SiCH observed that three or four black larvae of A. 

 grossulariata which he had found had all produced quite 

 normal imagines. 



Papilionid scent-scales. — Dr. F. A. Dixey exhibited 

 drawings of the specialised scales from the " greasy patch " 

 on the fore-wing of Ornithoptera 'priamus f. eujyJiorion, Gray, 

 (S, and from the fold of the hind-wing of Cosmodesrmis 

 macleayanus, Leach, cJ, C. sarpedon f. choredon, Feld., <$, C. 

 eurypylus f. lycaonides, Eothsch,, ^, and C. eurypylus f. 

 lycaon, Feld., cJ, 



The Pkesident, the Eev. G. Wheelek, and Mr. Sich made 

 observations on this exhibit. 



African Asilids.^ — Mr. S. A. Neave exhibited some flies 

 of the Asilid genus Hyperechia from Mlanje, Nyasaland. 

 They included a number of bred specimens of Hyperechia 

 consimilis, Wood, found breeding in the same tree-trunk as a 

 colony of the model Xylocopa nigrita. Pieces of the tree 

 showing the burrows of the two insects were also exhibited. 



Hyperechia marshalli, Aust., hitherto only known from the 

 type in the Hope Department, with its model Xylocopa 

 flavorufa, de G. 



Mr. Neave also exhibited 9 examples of 3 species of 

 Hyperechia captured " with prey," and pointed out that in 

 every case the prey is Hymeuopterous. 



Messrs. E. E. Green, G. A. K. Marshall, J. E. Collin, 

 and the Eev. G. Wheeler commented on the exhibit.
