"Habitat sub cortice arborum emortuarum, prtesertim abietis ; in Westrogothise 

 silva Kinnensi exueta." — Gyllenhal. 



Obs. — There appears to be a great diversity of opinion regarding this species ; 

 owing to a want of care in determination, or perhaps from still greater carelessness 

 in affixing labels, I have found S. pusillum represented in various collections l)y 

 examples of the following extremely dissimilar species, viz. S. Damryi, S. densatum, 

 S. latum, Artltrolips humilis, Scricodcrus lateralis, Anisom. Revclierii, &c. In the 

 collections of M. de Marseul, M. des Gozis, and Herr Reitter the exponents of .S'. 

 pusillum are uniform, and I have followed their guidance in my own description of 

 the species.
