dead bud of a tree ; they appear to be constructed of the same ma- 

 terial as the nests of the Chlamys. The insects undergo these changes 

 within the nests, the larva fastening the orifice to the stem of the 

 tree, and then turning itself round so as to escape (when arrived at 

 the imago state) from the opposite end. In one of these nests a 

 number of parasitical Ichneumones adsciti were found. 



A note was read from the Rev. R. A. Cox, relative to the appear- 

 ance of immense numbers of minute black caterpillars on the surface 

 of pasture grounds in the parish of West Camel, Somerset, to the 

 extent of twenty acres. The caterpillars were regarded by Mr. 

 Stephens as those of a species of Melitcea, which are known occa- 

 sionally to congregate in great numbers. 



The following memoirs were read :

Disphericus, W. Caput elongatum, labrum brevissimum s antice 

 emarginatum, labium apice subemarginatum, palpi articulo externo 

 • obtriangulari, antenna longce, subcrassiores, thorax valde convexus 

 fere globosus. Femora antica crassiora, tibia intus emarginatce.
