ON THE CLAVICORNES. 423 



arsenic four ounces, of white soap four ounces ; dissolve 

 the camphor in a sufficient quantity of spirit of wine ; pound 

 up the soap along with it, and preserve the whole mixture 

 in a glass vessel, properly stopped, to be vised as occasion 

 may require. 



The Byhrhi are oval, almost globular insects, which have 

 very great relations with Dermestes, Anthrenus, and Sphe- 

 ridium, being only distinguished from them by the form of 

 their antennae. When these insects are touched, they with- 

 draw their head into the corslet, apply their antennae and 

 feet against the body, and counterfeit death. They remain 

 for some time in this position, after which they resume their 

 walk. They are to be met with in the fields, on the edges of 

 roads, and other such like places. They very rarely employ 

 their wings. 



The most common species of this genus is Byrrhus pilula^ 

 which is found throughout Europe, in fields and pathways, 

 and in sandy places. 



The Heteroceri frequent the borders of marshes, and 

 dig holes there with their feet for the purpose of concealing 

 themselves. But they very speedily come out of them if the 

 earth about them be disturbed. 



The Geouissi have some relations with Byrrhus. They 

 are very small insects, and seem to frequent, by preference, 

 humid and aquatic situations. 



We have now noticed all that is of any popular interest 

 in this extensive family of Coleoptera ; but as our readers 

 will see, we have been under the necessity of passing over 

 many of its sub-genera, as affijrding no materials for this 

 portion of our work.
