This curious little insect has never hitherto been figured. I 

 have included it with the Dermestidae because the trophi and 

 antennae seem to agree best with that family. There can be 

 little doubt that it is nearly allied to Trinodes, although it has 

 a good deal the habit of a Hister, yet I should say it is not so 

 nearly related to Byrrhus as to justify its being placed in the 

 same family ; until however Dorcatoma, Trinodes and Lim- 

 nichus are well investigated, it will be difficult to assign to 

 Aspidiphorus its natural situation. 



Sturm placed it between Trinodes and Byrrhus, and in the 

 Guide I adopted the affinities of Dejean and arranged it be- 

 tween Trinodes and Nosodendron (pi. 246). 



Aspidiphorus orhiculatus was first discovered in England, I 

 believe, by Mr. Spence near Hull in Yorkshire : it has since 

 been captured the beginning of July in a larch plantation at 

 Marton near Stockton on Tees by the Rev. G. T. Rudd ; and 

 near Sherburn in the same county, on a felled tree in a fir 

 plantation in company with Scaphidium 4>-maculatum (pi. 379), 

 by A. Mathews, Esq., who informed me that they appeared to 

 be covered with mud. 



For my specimens I am indebted to F. Walker, Esq., who 

 took them near Southgate. Mi*. E. Doubleday also found a 

 pair in moss the middle of November on the borders of Ep- 

 ping Forest. 



The Plant is Ci/noglossimi officinale (Common Hound's- 

 tongue).
