COLEOPTERA OF SOUTHWESTERN PENNSYLVANIA. 879 



ADDITIONAL REMARKS. 



Platynus caudatus Lee. — One fine example of this rare species is in my col- 

 lection, taken by Mr. H. Klages near Pittsburg ; its appearance is decidedly 

 subterranean, being of the same color as Anophthalvius tellkampfii ; the type 

 is described as rufopiceous, but in the present example there is only a slight 

 susjiiciou of piceous on the head. The unique type is marked Western 

 States, and it also occurred to Mr. C. Dury near Cincinnati, Ohio. 



Stenolophus alternans Lee. — This rare and graceful species has occurred to 

 me thrice, once in the bed of the Little Beaver River in southeastern Ohio, 

 and twice near Pittsburgh. Like its sub-congener Aepus m.arinns Stroera. of 

 Europe, it is subaquatic, living under stones, etc., in the bed of streams 

 partly submerged, or along their margins, having the habit of Schisocieniii 

 amphibius. The type was taken in Pennsylvania near Columbia, and the 

 species was also taken by Dr. LeConte, but further record of its occurrence 

 has not been observed. 



Dineutes americanus Linn. — This name was substituted for assimilis Kirby 

 (Aube), because of the synonymy of Dr. Horn in his review of the Olivierian 

 species (Tr. Am. Ent. Soc. xiii, 138). Mr. Eoberts, in his Monograph, page 

 283 of the present volume, adopts assimilis Aube. If asdmilis Aube and as- 

 simiUs Kirby are identical, the latter has precedence by one year, on the 

 authority of the respective dates of publication. 



Eleusis nigrellus Lee. — Two examples of this small species occurred here in a 

 mountainous place, under bark of maple ; the types were from Southern 

 California, and further record of occurrence has not been observed. The 

 Pennsylvania examples are identical with those in my collection from 

 Southern California. This is a long stride, but close collecting will doubt- 

 lessly in time close the gap. I have Siagonium punctatum Lee. from Arizona, 

 and took it here at the same time with E. nigrellus. What has become of 

 Elensin canadensis described by Dr. LeConte, Tr. Am. Ent. Soc. iii. 298 ? 



Perthalycra murrayi Horn. — Apparently rare in the Atlantic region, there 

 being one example in Dr. LeConte's collection labeled Georgia {Horn), and 

 an example taken here by myself. It seems common on the Pacific coast, 

 ranging from San Francisco northward to Oregon and western Nevada (Horn). 



Leptura emarginata Fab. — Through the liberality of Prof. Schmitt examples 

 of this regal species are in my collection from North Carolina. An example 

 taken near Pittsburgh was brought me for identification, and others have 

 been reported. This species and gigas, from western Texas, seem closely 

 related — probably racial. 



Leptura nana Newm. and var. hxmatiies Newm. — Mr. Henshaw, in his cata- 

 logue of 1895, has overlooked the most recent synonymy of this species as 

 established by Dr. Horn, Tr. Am. Ent. Soc. xv, 301 ; see also Can. Ent. xxi, 

 32 and 108 ; " Entomologica Americana" vi, 12.5. 



Nodonota tristis Oliv. — N. convexa Say, N. puncticoUis Say ; by perhaps an over- 

 sight, convexa and puncticoUis are not catalogued as species by Mr. Henshaw, 

 1895.
