same collector, were in his opinion taken on the mainland and not 

 on St. Paul Island. At any rate, the species of Calathus, three in 

 number, said to be from St. Paul Island, are apparently hitherto 

 undescribed. The species of the Pacific coast known to me thus 

 far may be described as follows: 



Species of California, larger and stouter in build 2 



Species of Alaska and neighboring islands, notably smaller and nar-

2 — Third antennal joint much longer than the fourth 3 



Third antennal joint not or but very slightly longer than the fourth.. . .4 

 3 — Elytra without trace of a subbasal puncture near the scutellum; 

 last palpal joint slender as usual, but with the tip transversely 

 truncate. Body elongate-suboval, moderately convex, shining, the 

 elytra opaculate; color pure bright testaceous, the elytra piceous- 

 black, with the reflexed edge testaceous; head oval, with moderately 

 convex eyes, not three-fifths as wide as the prothorax; antennae 

 not very slender, three-fifths as long as the elytra; prothorax a fifth 

 wider than long, the deeply sinuate apex scarcely three-fourths as 

 wide as the base; sides feebly arcuate; basal angles right, slightly 

 blunt; surface nearly smooth, the anterior impression distinct, the 

 posterior obsolete; sides rather strongly and abruptly reflexed, 

 becoming broadly declivo-explanate basally; elytra more than one- 

 half longer than wide, nearly a third wider than the prothorax, the 

 sides evenly and moderately arcuate to the base; apex evenly and 

 gradually ogival; striae very fine, the intervals just visibly convex; 

 dorsal punctures very fine, four in number. Length (9) 9.5 mm.; 

 width 3.9 mm. California (Mokelumne Hill, Calaveras Co.), — 



Blaisdell ignicollis n. sp. 



Elytra with a small subscutellar puncture, not quite at the base; last 

 palpal joint rather inflated, elongate-oval. Body less elongate and 

 with notably inflated elytra, obscure rufous, the legs more flavate; 

 elytra black, with dull rufous reflexed margins; surface alutaceous, 

 the elytra opaque, the head nearly as in the preceding; antennae 

 slender, two-thirds as long as the elytra; prothorax subsimilar in 

 form and structure but relatively not quite so large and with notably 

 rounded basal angles, the apical not so prominent and more obtusely 

 rounded at tip; anterior transverse impression completely obsolete; 

 sides similarly reflexed and basally explanate; elytra shorter, rather 

 less than one-half longer than wide, two-fifths wider than the pro- 

 thorax, the sides slightly more arcuate; striae very fine, the intervals 

 flat; dorsal punctures small, four in number. Length (9 ) 8.7 mm.; 



width 3.65 mm. California (Monterey) montereyanus n. sp. 



4 — Body very much larger than in any other American species of the 

 genus. Form stout, oblong-oval, testaceous, the elytra blackish, 

 with the usual testaceous reflexed margins; lustre moderately 

 shining, the elytra opaculate in both sexes; surface very moderately 

 convex; head subtriangular, longer than usual, more than half as 

 wide as the prothorax, the palpi slender, with obtusely pointed apex;
