AMERICAN COLEOPTERA. 149 



the only species remaining valid of all those described by Walker in 

 " Naturalist in British Columbia." 



Aaaphes verna % Gand., is morio $ Lee. 

 Asaphes coracinus Cand., is carbonatus Leo. 



The characters given by Candeze for the separation of these species 

 appear to be those of a sexual nature. An examination of large series 

 of Asaj^hes has shown that the females have the striae near the suture 

 very feeble or almost entirely obliterated, while in the males the striae 

 are normal. This character with the narrower thorax of the % and 

 the wider thorax of the female show the identity of the species above 

 cited. Other synonyms on the same basis remain to be determined 

 among the species of Asaphes but these must remain for a general 

 revision. 



EUCNEMID^E. 

 Entomophthnlmus pallens Bonv., is rvfiolus (Lee.) 

 Ti'itjonopleurus rugulosus Bonv., is from Victoria, N. S. W., and not 

 United States. 



Schizophilus trilohatus Bonv., and Nematodes simplex Lee, are 

 Schiz. subrufus (Rand.) 



CLERIDJS. 

 In the Review and Magazine of Zoology published at Paris, appears 

 a paper entitled " Catalogue des derides de la Collection de M. A. 

 Chevrolat," and which evidently bears date subsequent to Sept., 1874, 

 in which are described various North American species as new. With 

 the assistance of Dr. Leconte, the descriptions have been compared 

 with specimens as they stand in our cabinets with the following 

 results : 



Thanasimus m^lanocephalus Chev., is certainly a variety of nubilus 

 Kirby. 



Ht/dnocera fnnebris Chev., is B. scabra Lee. 



Pelonium pensylvanicum Chev., is probably a variety of Orthopleura 

 damicornis with oblique band behind the middle of the elytra. 



Pelonium militare Chev., is Enoplium humerale Horn, Trans. Am. 

 Ent. Soc, 1868, p. 135. 



Pelonium lineatocolle and /iliolus Chev., appear to be the same thing, 

 the former is undoubtedly Lebasiella maculicollis Lee, Trans. Am. 

 Ent. Soc, 1874, p. 63. 



LYMEXYLIDJS. 

 Hj/lecoefus americanus $ Harris, is identical with lugubris Say.
