a brief interval, during which period the second larval form is closely 

 imitated, followed by a moult ; after which the true pupa is developed, 

 having all its members severally swaddled in another pellicle, to be again 

 discarded on attaining the perfect state, when the black head of the imago 

 (in the Stylopidcn) is thrust forward to the apex of the puparium, about the 

 eighth day after the protrusion of the latter as aforesaid. 



" This larviform condition of the pseudo-pupa in Hylechthriis I have 

 verified by extraction, such preliminary stage serving to complete the 

 analogy with the Melo'idce, in other respects. 



" The Prosopis communis having been found stylopized in England, its 

 ordinary parasite, the Hijlechthrus, may not improbably be discovered in 

 connexion therewith, by collecting the larvae of the former from desiccated 

 briars, dock stems, and other known habitats, and keeping them on cotton- 

 wool until maturity." 



A collection of such larvae and nymphs from Epirus was also exhibited, 

 including one of the latter (placed apart) distended and yellow, about to 

 produce a stylopized imago. 



Miss E. A. Ormerod exhibited a soft, fleshy, gall-like formation found 

 on Wiododendron ferrugineinn at Merton, and believed by Dr. Thomas to 

 be a fungoid growth. 



Mr. Fitch stated he had often possessed specimens of this supposed gall, 

 and had attempted in vain to breed an insect from them ; he was therefore 

 disposed to concur in Dr. Thomas's view. 



Mr. T. E. Billups exhibited a specimen of Heptaulacus villosus from 

 Box Hill. 



Mr. C. 0. Waterhouse stated that about five years ago he had taken 

 from forty to fifty specimens of this rare beetle in a chalk-pit in Fresh- 

 water Bay. 



Papers read.

 with descriptions of new species."
