ClCINDELID/E AND CARABID/E 119 



Sides strongly sinuate, becoming straight and almost parallel for a long 

 distance before the angles, which are right though similarly blunt. .6 



5 Form elongate though moderately broad and convex, deep black, 

 shining, the elytra less shining and alutaceous, almost similarly in 

 the sexes, which are almost completely similar otherwise as well ; 

 head rather large, almost three-fourths as wide as the prothorax, the 

 impressions rather broadly concave, the epistoma and labrum rather 

 broad, evenly sinuate from side to side; prothorax not quite as 

 long as wide, the sides rounded, rather strongly converging behind 

 about the middle, becoming scarcely less than straight, the angles 

 very obtuse and distinctly rounded; base about two-thirds the maxi- 

 mum width; surface rather strongly reflexed at the sides, the inner 

 impression long and distinct, the surface thence to the sides convex, 

 the outer impression obsolete; anterior angles moderately broadly 

 rounded; elytra nearly three-fourths longer than wide, evenly oval, 

 moderately convex, two-fifths wider than the prothorax, the sides 

 almost evenly rounding to the basal ridge, the denticle completely 

 obsolete; striae rather fine but deep, impunctate, the intervals nearly 

 flat, feebly convex laterad, the scutellar stria rather long, the first 

 stria broadly interrupted near the base; hind tibiae (cf ) strongly 

 crenulate internally, the tarsi rather long. Length (cf 9 ) i7-5~ 

 18.0 mm.; width 6.3-6.7 mm. California (San Clemente Island). 

 Five remarkably uniform examples gliscans n. sp. 



Form very elongate and notably narrow, rather strongly convex, black, 

 moderately shining, the elytra decidedly opaque; head fully two- 

 thirds as wide as the prothorax, the impressions distinct, unusually 

 widely separated, the epistoma strongly, the labrum feebly, sinuate; 

 prothorax nearly as long as wide, formed almost as in the preceding, 

 except that it is relatively smaller in size, with the oblique sides 

 posteriorly broadly but sensibly sinuate, the angles a little less obtuse 

 and but slightly blunt; surface rather strongly reflexed at the sides, 

 more gradually sloping toward the apical angles, which are similarly 

 moderately rounded, the basal impressions similar but with the 

 surface thence to the sides flatter, the outer impression obsolete; 

 base nearly three-fourths the maximum width; elytra very elongate, 

 evenly oval, almost four-fifths longer than wide; striae fine but rather 

 deep, finely punctate, very distinctly toward the sides, the intervals 

 nearly flat, sensibly convex laterad; humeral denticle distinct, the 

 scutellar stria rather long, oblique, the first not interrupted; tarsi 

 moderate. Length (9) 16.5 mm.; width 5.8 mm. California 

 (between Indio and Colton), Dunn ovalipennis n. sp. 



6 Body rather stout and convex, black, moderately shining, the elytra 

 strongly alutaceous; head moderate, the impressions separated as 

 usual, deep and distinct, nearly parallel; prothorax much larger than 

 in either of the preceding, about as long as wide, the sides broadly 

 rounded, becoming evidently converging only well behind the 

 middle, the sinuation rather abrupt; angles right, rather sharp; 

 base nearly four-' fths the maximum width; surface not very convex, 

 sloping gradually to the abruptly and strongly reflexed marginal 

 bead, the inner impression rather small, somewhat sharply defined,
