246 GEO. H. HORN, M. D. 



rectangular or slightly obtuse, margin explanate, more widely flattened pos- 

 teriorly, surface feebly convex, variably punctured, sometimes very indistinctly 

 or again with evident punctures at the sides and base. Elytra oval, wider than 

 the thorax, very little narrowed at apex, surface finely striate, striae finely 

 punctured, intervals flat, the third and fifth with three or four fine, sometimes 

 scarcely visible punctures situated near the second and fourth strise. Body 

 beneath with very sparse punctures and very little pubescence. Length .20 — 

 .24 inch ; 5—6 mm. (PI. V, fig. 7). 



The males have the first three joints of the anterior and the first 

 two of the middle tarsi dilated, the latter slightly. 



This species exhibits some variations in the lustre of the surface and 

 in its sculpture, some being quite opaque, others moderately shining, the 

 latter have the striae and punctures more evident and the punctuation of 

 the thorax better marked. I believe they constitute but one species. 



As the preceding species shows a resemblance to Nebria so this 

 resembles Calathus i-uficoUh in smaller size, which has also punctures 

 on the third elytral interval as fine as in this species. 



Occurs in Oregon, Washington Territory, western Nevada and 

 northern California. 



AGYRTES Frohl. 

 Head oval not constricted behind the eyes, the latter round and moderately 

 prominent. Labrum short, transverse, broadly emarginate. Maxillary palpi 

 moderate in length, first joint very short, second obconical, slightly arcuate^ 

 third short, stout, fourth ovate. Antennae moderately short, attaining the hind 

 angles of the thorax, inserted under a feeble frontal margin, first joint robust, 

 cylindrical, suddenly constricted at base, second and third obconical, the latter 

 a little longer and more slender, 4 — 6 short moniliform, the last five forming 

 a loose club, the eleventh broadly oval. Anterior coxal cavities partly closed 

 by a slender prolongation of the epimera. Middle coxse narrowly separated. 

 Posterior coxae contiguous. Elytra very narrowly margined, their epipleurse 

 narrow. Legs rather short, tibise spinulose externally. Tarsi slender. Form 

 oblong, parallel, body winged. 



This genus as noticed by Lacordaire seems to make the lead towards 

 the Anisotomini. One species only is known in our fauna. 



A. longlllus Lee. {Necrophilus). — Oblong, black or pieeous, shining, glab- 

 rous. Head coarsely punctate. Thorax one-third wider than long, narrower 

 in front, sides feebly arcuate from the base, margin not explanate, apex very 

 feebly emarginate, the angles obtuse, base feebly arcuate, angles obtuse, diso 

 moderately convex, surface sparsely punctate, punctures a little denser toward 

 the sides. Elytra a little wider than the thorax, nearly twice as long as wide, 

 sides very nearly parallel, feebly arcuate, surface moderately deeply striate, 

 strise finely crenately punctured. Body beneath rather coarsely not densely 

 punctured. Femora sparsely punctate. Length .12 — .20 inch; 3 — 5 mm. 

 (PI. V, fig. 9). 



The anterior tarsi of the male have the first two joints feebly dilated. 



Occurs from northern California to Vancouver, rare.
