dark-pitch colour, confirm the accuracy of this determina- 

 tion." Now I would observe that if Carabus lugubris of 

 Duftschmidt is really specifically identical with Agonum 

 versutum of Sturm, it appears to me that Duftschmidt's 

 trivial appellation must be adopted in preference to Sturm's, 

 it being twelve years antecedent in publication ; but I am 

 inclined to think that Duftschmidt's indication, " Diejlugel- 

 decken sind einfach gestreift" (the elytra are simply striate), 

 and the characters assigned by him to the prothorax of his 

 C. hgubris, render its identity with versutus, Sturm, some- 

 what doubtful ; moreover, Dr. Schaum does not assert that 

 the insect labelled in Megerle's Collection Car. lugubris, 

 Duft., had been in any way authenticated by this author.

 Allied to H. nubilus, but usually larger, narrower, the 

 raised longitudinal ridges on the thorax more prominent, the 

 elytra more parallel, the interstices between the striae of 

 punctures less raised, pilose.
