118. For K. read A? 



125-6. Dr. Le Conte thinks Amniscus marginellus | Dej. Hold. 

 identical with A. aculifera S. and in a letter states that " Say was in 

 error when he wrote tip entire, as they are truncate in all the genus." 



132-3. Dr. Le Conte thinks Amniscus sticticus and A. macula 

 identical. 



138. Lamia facetus Say, is stated by Dr. Le Conte to be a Le- 



lOPUS. 



145. Leiopus symmetricus. Syn, L. ru fiventris ^ -ffarris. 



151. Having now a specimen of this species, I am able to refer it 

 to ExocENTKus instead of Pogonocherus, in which it was provi- 

 sionally placed. 



152. Dr. Le Conte thinks this should be considered an Exocen- 

 TETTs, and he has doubts of Desmiphoea being a good genus. 



158. For Monohammus maculosus read confusor Kb. N. Z. p. 

 168. 



160. For M. tomentosus read marmorator Kh., 169.

 been questionable. 



164. I have received specimens of Plectrodera scalator from New

 Missouri. 



180. C. lateralis appears in June and July. 



188. Saperda pergrata Say (now in Cab. Le C.) is a Stenostola. 



190. Atimia tristis is Clytus confusus Say, as Dr. Harris has re- 

 cently shown me. It will of course take Say's trivial name. 



191. I think it best at present to refer Ataxia to Stenidea. 



192. Stenostola fuscipes Say, placed in this genus by Dejean, is a 

 Sapeeda, and the % of Saperda discoidea F. The two have been 

 found in coitu by several observers. 



195. O. myops. Add — a small spot upon the humeri, another 

 between the anterior and medial feet ; superior and posterior margin 

 of the mesosternum, and a lateral blotch upon the 2d and 3d abdomi- 

 nal segments, black, Pennsylvania in June, on Acer. 



201. Oberea monostigma. The eyes are distinctly divided in 2 

 by the antennse, the larger division being inferior. This is considered 

 a generic character, and I accordingly propose the name Obeeopa,
