mani; and I do not see the propriety of removing Patrobus 

 from a near connection with Calathus and Platynus, to place it 

 where Kirby lias put it, near to Blethisa, etc. 



Dejean was not acquainted with the male of his Metrius con- 

 tractus, the only species he had examined. I think he was 

 wrong in putting it with his division of Simplicipedes. The 

 tarsi of the males in this genus show that they should go among 

 the Patellimani. The palpi are almost exactly like those of 

 Diccelus ; the short antennas remind you of those of Panagwus ; 

 the emarmnation of the tibia also removes the insect even

from the neighborhood of Nebria, etc. It is, in fact, ope of 

 those insects which serve beautifully to connect the Patellimani 

 with the G-randipalpi. Artificially, it will come between Eury- 

 soma and Panagceus, for it has a bifid tooth in the emargination 

 of the mentum, two dilated joints (the second much smaller 

 than the first, but covered beneath with the same kind of 

 brush) to the first pair of tarsi in the males, and the last joint 

 of the palpi subsecuriform (as in Diccelus, Chlcenius, etc.). 

 Artificially I say it will come between these genera, but I con- 

 ceive its natural place to be near to Oodes, Hembus and -Diecelus, 

 and especially near the latter.

CAMBRIDGE, Nov. 29, 1852. 



Are you aware that our big Buprcstis virginica is the true 

 B, Mariana of Linnaeus ? Such is the fact, as you will discover 

 on consulting Linnaeus' Museum Ludovicaa Ulrica) Reginas, 

 where it was first described. 



I am glad to be able to set you right in one instance where 

 you regret having changed one of Say's names, that of Poecilus 

 clialcites. The change was unnecessary ; and Germar's Poecilus 

 clialcitis (not clialcites') is of later date than Say's chaleites.
