Elater semivittatus Say. To this species Gorijinhites trist.is Caml., 

 should probably be referred. 



E. Sa^i Lee, seems not distinct from militaris Harris. 



E. socer Lee, is impolitus Mels. 



E. manipularis Cand., is HEPATICUS Mels. 



E. molestus Lee, is luctuosus Lee. 



E. fuscafus Mels., is pedalis Germ., which seems to be only 

 NIGRICANS Germ. 



E. lacustris Lee., is pullus Germ. 



E. palans Lee, seems not distinct from collaris Say. 



E. deletus and fusculus Lee, are color variations and very doubt- 

 fully different from mixtus Hbst. 



In Elater there is much other synonymy caused by the separation 

 of species from color alone. These will be given after a closer study 

 of true specific differences. 



Anchastus FUSCUS Lee, is an Ischiodontus. 



A. longulus Lee, is the male of digitatus Lee 



Ischiodontus ohiitus Cand., appears to be simplex Lee 



Melanotus cuneatus, incertus and decumanus Lee, seem not to differ. 



M. tenellm Er., is insipiens Say. 



Limonius pubicollis Lee, is auripilis Say. 



L. Ulkei Horn, is the female of mirus Lee 



L. semiseneus Lee, is basillaris Say, with pale elytra. 



L. ecfi/jjus Say, is agonus Say. 



L. quadrimaculatus Horn, should be referred to Megapenthes. 



Athous rejiexus Lee, is rufifrons Rand., of uniform brown color. 



A. debilis Lee, is a Monocrepidius. 



A. maculicoUis Lee, and Jiava72(jularis Horn, are color varieties of 

 acanthus Say. 



A. BICOLOR Lee, and discai^ceatus Say. — In these two species 

 the prosternal sutures are double, and excavated in front as in 

 many Limouius, differing in this respect from all the others in 

 our fauna. A similar occurrence of double sutures is found also in 

 Corymbites sulcicollis and rupestris, in which the tarsi also vary 

 from the normal type and approach Asaphes. 



The above synonymy is such as has been noticed in a rearrange- 

 ment of the species of my cabinet to this point. It is my desire 

 to present from time to time tables of the genera, the great accumu- 

 lation of material now rendering it possible to arrive at some idea 

 of what constitutes a species.
