341. C. (Elater) semivittatus Say, tristis, Caud. 



Specimens of iri-'itls, taken in Japan, on comparison, do not differ 

 from se7nivittatiis, which is believed by Dr. Horn to be the older 

 name. Horn, x, 228; T. vii, p. xvi.

342. Chalcophora virginiensis Drury, C. angulicollis Lee, C. mariana 

 Linn. 



These names in the catalogues are specific. Numerous specimens 

 of virginiensis from the eastern Atlantic States to Florida ; of angu- 

 licollis, from the Rocky Mountains and Vancouver, and of mariana 

 from Europe, have been seen and compared, with the result that 

 there has been no character observed permanent enough to more 

 than separate them into geographical races. The external sexual 

 characters are apparently the same. There are as valid reasons for 

 making species of at least two other forms which I have seen as of 

 the above.

343. Mela ophila longipes Say, immaculata Maun. 

 This species is often mentioned in our literature as, and has been 



labeled in many of our collections, appendicidata Fab., which, on 

 comparison with several specimens in hand it may prove to be (Horn, 

 T. x, 104). It is very widely distributed. " Maine to Alaska," Horn. 

 Hudson Bay ; Vancouver ; Rocky Mountains to New Mexico ; Lake 

 Superior. I take it here in Pennsylvania, and have it from West 

 Virginia and Ohio. General in Europe Arctic Siberia ; Kamts- 

 chatka ; Siberia generally. T. Am. P. xi, 211; Col. Am, 108; 

 Heyden, 117. 



344. M. Drummondii Kirby. 

 Dr. Horn regards this excessively variable species as nierely a 



slight variety of guttulata Gebl. (T. x, 104), which seems also to
