212 MEMOIRS ON THE COLEOPTERA 



rather more than one-half longer than wide, only a little wider than 

 the prothorax, parallel, with broadly arcuate sides and obtusely 

 ogival apex, the sinus rather short and very distinct; striae very fine, 

 the scutellar long, the intervals perfectly flat, becoming feebly convex 

 suturad, rather strongly sericeo-alutaceous in the female, the discal 

 puncture at apical fourth. Length (9) 9-8 mm.; width 3.8 mm. 

 California (Los Angeles Co.) extraneus n. sp. 



Body narrower and more oval than in extraneiis, very moderately convex, 

 shining, the elytra (9 ) very feebly alutaceous; color piceous-brown, 

 the elytra but little darker than the anterior parts; under surface 

 more rufous; slender antennae and the legs pale testaceous; head 

 three-fifths as wide as the prothorax, with rather constricted neck, 

 prominent eyes and minute feeble foveae, also usually having a minute 

 punctiform impression at the centre of the vertex; prothorax one-half 

 wider than long, truncate at base, sinuato-truncate and slightly 

 narrowed at apex, the sides rounded, somewhat straighter basally, 

 the basal angles obtuse, with their apices blunt; surface impunctate, 

 feebly subdepressed latero-basally and with feeble reflexed edges, 

 broadening and disappearing gradually behind the middle, nowhere 

 at all abruptly defined, the foveae short, sublinear but very broadly 

 and feebly impressed, the median stria short and feeble; elytra one- 

 half longer than wide, with distinctly arcuate sides and obtusely 

 ogival apex, almost a third wider than the prothorax, the sinus very 

 distinct; striae very fine, the intervals flat, sometimes feebly convex 

 suturad; hind tarsi slender, the basal joint not as long as the next 

 two and equal to the fifth. Length (cf 9 ) 8.8-9.4 rnm.; width 3.6- 

 3.7 mm. Arizona (probably southern) calathoides n. sp. 



7 Form somewhat as in the preceding but narrower and still more 

 Calathus-\ike, pale testaceous in color throughout, the elytra rather 

 pale piceous-brown; surface shining throughout (cf), the elytra 

 feebly opaculate (9 ); head nearly as in the preceding but somewhat 

 smaller, the antennae still longer and more slender; foveae very minute, 

 scarcely visible; prothorax two-fifths (cf ) to slightly more (9 ) wider 

 than long, the apex sinuato-truncate and much narrower than the 

 base, the sides rather strongly, subevenly rounded throughout, the 

 margin narrowly deplanate anteriorly, gradually becoming rather 

 broadly so basally and somewhat abruptly defined throughout, the 

 foveae extremely feebly impressed, not linear, the stria short, medial 

 and feeble; elytra more than one-half longer than wide, nearly a 

 fourth wider than the prothorax, the sides broadly arcuate; sinus 

 very shallow and obsolescent; striae very fine but distinct, the inter- 

 vals flat ( 9 ) or feebly convex (cf ); hind tarsi very slender, the first 

 three joints decreasing uniformly and rapidly in length, the first 

 somewhat longer than the fifth. Length (cf 9 ) 8.0-9.3 mm.; 

 width 3.2-3.5 mm. Indiana and Wisconsin. [Ilarpahis testaceus 

 Hald.] testaceus Hald.
