COLEOPTERA OF SOUTHERN CALIFORNIA. 207 



DESCRIPTIONS OF NEW SPECIES. 

 i. Notiophilus obscurus, sp. nov. 



Black, bronzed, sides of elytra broadly but obscurely yellow toward the 

 apex; base of antennae, tibae and tarsi more or less pale. Head slightly 

 wider than the thorax, front 8-10 striate. Striae of elytra scarcely 

 impressed, not effaced at apex, slightly approximated by pairs, the exter- 

 nal interspaces faintly alutaceous but shining; there are normally three 

 discal tuberculate punctures or foveas, one before the middle and two 

 subapical. Prothorax beneath very sparsely punctate. Length 5-5.5 mm. 



Habitat: San Bernardino Mountains, at an altitude 

 of from 6,000 to 7,000 feet. 



The above characters are about the only ones that 

 are of general use for comparative purposes in this 

 genus, and therefore a more detailed description is 

 unnecessary. N. obscurus seems among our species to 

 be most nearly related to a form occurring in Vermont 

 and the White Mountains of New Hampshire, and 

 which passes as N. sylvaticus in collections; this latter 

 differs however by having the sides of the elytra yellow 

 throughout, the striae impressed and more strongly 

 punctate, the intervals narrower, and the front less 

 numerously striate. The White Mountain species is 

 quite surely not the true N. sylvaticus, which is a west 

 coast species (Alaska, Vancouver, Washington) with 

 smaller head and less strongly sculptured elytra, and 

 it is quite as certain that it is very close to the European 

 N. biguttatus. The latter agrees very nearly with A 7 . 

 obscurus in the color of the elytra, but is otherwise 

 scarcely distinguishable from the New England species. 



2. Dyschirius unipunctatus, sp. nov. 



Small, moderately stout, black with distinct bronze-green lustre, legs 

 and antennae rufous or brown, the latter somewhat darker apically.
