very acute and laterally subprominent; apical angles well defined 

 though slightly blunt at tip; impressions and reflexed side margins 

 punctate, the anterior impression shallow, the posterior very deep; 

 fovea very deep, oblique; elytra four-fifths longer than wide, a third 

 wider than the prothorax, gradually just visibly wider behind, the sides 

 feebly arcuate, very rapidly rounding at base; apices very oblique, 

 almost straight, rounded as usual at the suture; striae moderately coarse, 

 with fine and widely spaced punctures; intervals nearly flat, the third 

 with four punctures, which are confluent with the third stria; tarsi very 

 long and slender. Length 9.2-9.7 mm.; width 3.65-3.75 mm. New 

 Hampshire (Mt. Washington). Two female examples. 



Differs much from lahradorica in its narrower form, less abbrevi- 

 ated and laterally less strongly rounded prothorax, with more 

 prominent acute basal angles, narrower and posteriorly somewhat 

 inflated elytra, intense black coloration and almost non-diaphanous 

 thoracic sides ; the sides of the elytra are more rapidly and strongly 

 rounded at base. It is probably allied rather closely to mcesta Lee, 

 from Lake Superior, but is apparently more convex. 



The two following species are allied to the west coast eschschoUzi, 

 having entirely very pale legs : 



Nebria transversa n. sp. — Stout, the outline much broader than in 

 eschschoUzi, the surface fully as convex, shining, the anterior parts and 

 under surface rufo-piceous, the elytra black; legs very pale, long and 

 slender; head large, less triangular than in the preceding section, barely 

 as long as wide, the prominent and well developed eyes at a greater 

 distance from the base; surface nearly smooth, with two nubilously paler 

 spots on a line through the eyes; mandibles rufous, the inner margin 

 black; palpi clear rufous throughout, the last joint very obtuse at apex, 

 one-half longer than the third; antennae missing in the type, the basal 

 joint pale testaceous; prothorax short and very broad, fully three-fourths 

 wider than long, widest at anterior two-fifths, the inflated sides strongly 

 rounded anteriorly, gradually converging but barely less arcuate behind 

 to the gradual sinus, thence parallel to the right and sharp angles; 

 margins narrowly deplanate, with a single series of punctures, the edge 

 finely but sharply reflexed; apex broadly sinuate, wider than the base, 

 with rather blunt short thickened angles; base transverse, the sides 

 obtusely projecting behind to slight degree; transverse impressions 

 rather deep, sparsely punctate, the median stria fine; fovese small, 

 somewhat deep, rather close to the angles; elytra two-thirds longer than 

 wide, one-half wider than the prothorax, gradually inflated behind, with 

 broadly arcuate sides, somewhat rapidly rounding at base; surface 

 smooth, with an obtuse arcuate longitudinal ridge at apex; striae moder- 

 ate, slightly impressed, finely irregular but not definitely punctate, more 

 clearly punctulate basally; intervals not quite flat, the third with four 

 moderate impressed punctures adhering to the third stria. Length 11.5 

 mm.; width 4.8 mm. Oregon (Corvallis). A single female example.
