258 DESCRIPTION OF NORTH AMERICAN INSECTS. 



Nemognatha. 



1 1 . N. nemorensis. Black, hairy ; mouth and thorax fer- 

 ruginous, with three hasal impressions black ; elytra punc- 

 tured, substriate ; suture raised. 



Length 3-10ths of an inch. 



Inhabits the woods of North Carolina. 



This interesting insect is probably rare, for I never saw 

 but one specimen, found in May. The second joint of the 

 antennae is shorter than the first and the third : and all the 

 joints are very hairy. The maxillae which are usually bent 

 under are nearly as long as the antennae. 



In the above descriptions it is not unimportant to observe 

 that Dr T. W. Harris has found in the vicinity of Boston 

 Cicindela formosa, which Mr Say described from specimens 

 brought from the Missouri by Mr Nuttal. He and I have 

 also found there Clytus speriosus, described by Mr Say, in the 

 Appendix to Long's Expedition of 1823, as discovered on the 

 banks of the Wisconsan, Prairie du Chien. I have seen in 

 North Carolina a number of insects which he had found only 

 in the west,
