American Caraboidea 291 



extremely short and broad, confined entirely to the basal peduncle, not 

 entering the elytra, the latter two and a third times as long as wide, a 

 fourth or fifth wider than the prothorax, the sides parallel and almost 

 evenly arcuate throughout, only a little more so at base; apex obtusely 

 and evenly rounded; margins very finely reflexed; flanks with about five 

 impressed submarginal punctures; striae rather fine, somewhat abruptly 

 incised, not punctate; intervals flat, unevenly creased, without dorsal 

 puncture; subscutellar puncture distinct, as far from base as suture and 

 at the anterior end of the second stria, the short feeble and slightly 

 oblique scutellar stria forming a subdetached basal part of the first 

 stria and widely removed from the subscutellar puncture; side margin 

 ending at the humeri, the base slightly depressed, not margined; anterior 

 male tarsi moderately dilated, spongiose beneath; inner tibial tooth 

 beyond the middle strong, bearing a long spiniform seta similar to the 

 one at apex. Length (cT') 14.0 mm.; width 4.2 mm. Oregon (Josephine 

 Co.) , — Nunenmacher. 



Differs from matthewsi in its more slender form, violet and not 

 cupreous-red color, longer cephalic impressions, shorter third palpal 

 joint, more abruptly incised and less impressed elytral stria? and 

 many other features. 



Chlaenius Bon. 

 A considerable number of nondescript species have accumulated 

 in my collection during recent years, which it seems worth while 

 to make known at the present time as follows: 



Chlaenius umbritarsis n. sp. — Body of large size, nearly as in erythropns 

 but stouter, black, feebly shining, the elytra olivaceous-black and opaque; 

 under surface rather shining, deep black, the legs dark rufous, with 

 piceous-black tarsi; head four-sevenths as wide as the prothorax, with 

 prominent eyes, the surface coarsely punctate basally, except on the 

 neck, and with feebler ruguliform punctures laterally; median part 

 impunctate to the apex; impressions obsolete; palpi rufous, long, the 

 third joint a third longer than the fourth; antennae long, slender, fusco- 

 testaceous, each joint with a fine blackish carina; prothorax but little 

 wider than long, widest at the middle, where the sides are rather rounded, 

 thence converging and feebly arcuate to the apex, less converging and 

 feebly sinuate posteriad, the angles obtuse and blunt at tip; base trans- 

 versely sinuate medially, a third wider than the sinuato-truncate apex; 

 margins rather narrowly reflexed throughout; surface flattened medially, 

 coarsely punctate, more closely toward base, the stria greatly biabbrevi- 

 ated and very fine; foveae longitudinally impressed; elytra oblong, nearly 

 one-half longer than wide, three-fourths wider than the prothorax, the 

 parallel, very feebly arcuate sides rapidly rounding at base; subapical 

 sinus long and very distinct; striae fine, finely, not closely punctate; 

 intervals flat, finely, closely punctate; scutellar stria very long; under 

 surface punctured throughout, very finely, rather sparsely and unevenly 

 on the abdomen. Length (.9) 22.3 mm.; width 9.3 mm. Louisiana.
