REVISION OF TENEBRIONID SUBFAMILY CONIONTIN^E 133 



strongly convex, comparatively coarsely sculptured and is more 

 oval than in the eschscholtzi group, but otherwise resembles the 

 prevailing form in the latter, except that it is more completely 

 glabrous, no species being known to me having more than 

 very minute setse virtually wholly enclosed within the punc- 

 tures ; they may be known by the following characters : 



Elytral punctures more or less coarse and very conspicuous, the in- 

 teguments deep black throughout and strongly shining; habitat 

 near the coast 2 



Elytral punctures smaller and less conspicuous though invariably dis- 

 tinct, the integuments always deep black but frequently alutaceous ; 

 habitat further removed from the coast 6 



2 Sides of the prothorax strongly rounded and converging anteriorly, 

 becoming straight and parallel in rather more than basal half. 

 Form more oblong than usual, parallel, strongly shining ; head 

 strongly, rather closely punctate anteriorly, more sparsely toward 

 base, the sinus rather broad, moderately deep, subangular, the 

 lobes broadly rounded, not impressed, the anterior canthus broadly 

 rounded, more prominent than the posterior ; prothorax short, 

 fully four-fifths wider than long, the apex moderately sinuate, 

 barely three-fifths as wide as the base, the angles deflexed and 

 slightly obtuse but only narrowly rounded; base transverse, feebly 

 oblique at the sides ; surface finely, rather closely and distinctly 

 punctate, becoming somewhat coarsely so, though not much more 

 closely, toward the sides, the bead rather fine ; scutellum small ; 

 elytra one-half longer than wide, barely as wide as the prothorax, 

 the sides gradually converging and broadly rounded behind from 

 about basal third, the apex rather acutely ogival ; surface rugose, 

 especially behind, coarsely and closely punctate ; prosternum 

 strongly and closely punctured throughout, the process well 

 developed, very feebly constricted, circularly rounded at tip, very 

 strongly margined throughout ; hind femora rather coarsely, 

 moderately closely and conspicuously punctate, the abdomen 

 strongly and unusually closely so. Length n.o mm.; width 

 5.45 mm. ( ? ) . Probably near Puget's Sound. . .breviuscula n. sp. 



Sides of the prothorax strongly, subevenly rounded throughout, strongly 

 converging anteriorly, becoming parallel and less arcuate toward 

 base. Form oblong-oval, much more longitudinally convex; 

 head not very coarsely but strongly punctured, densely toward 

 the suture, more sparsely elsewhere, the sinus broad and unusually 

 shallow, circularly rounded, the lobes broadly rounded, impressed 

 near the margin, the anterior canthus evenly and broadly rounded, 

 more prominent than the posterior ; prothorax more than three- 

 fourths wider than long, the apex rather deeply sinuate, three- 

 fifths as wide as the base, the angles moderately deflexed, slightly 

 obtuse and well rounded; base broadly bis inuate, the angles rather
