486 Coleopterological Notices, IV. 



move elono^ate than in any of our other species, scarcely perceptibly 

 wider than long, with the sides distinctly convergent and nearly 

 straight from the base to between apical third and fourth, then 

 strongly rounded, then somewhat strongly convergent and nearly 

 straight to the apex ; base about three times as wide as the head, 

 the median lobe pronounced ; disk with a narrow ill-defined median 

 line, the punctures coarse, very deep and rather dense, somewhat 

 uneven in size. Elytra not very coarsely but deeply and abruptly 

 grooved, the intervals about twice as wide as the grooves, and all 

 coarsely, closely, confusedly punctured throughout their extent, and 

 coarsely rugose but polished, the second and third less coarsely, more 

 sparsely punctured and smoother. Length 4.5 mm. ; width 2.0 mm. 

 Middle States. 



16 Baris vespertina n. sp. — Oblong-oval, convex, polished and dark 

 piceous-brown througliout, the setfe long, stout, acuminate, strigose, sparse 

 but conspicuous, semi-erect and arranged without order on the elytra. Head 

 minutely but distinctly, not very remotely punctured, the beak not coarsely 

 but deeply, densely so, rugose at the sides, robust, moderately arcuate and 

 about three-fourths as long as the prothorax ; antennse inserted distinctly be- 

 hind the middle, the scape very short, club moderate, its basal joint polished, 

 pubescent toward apex. Prothorax one-half wider than long, the sides just 

 visibly convergent, evenly and distinctly arcuate to near the apex, then 

 gradually more strongly arcuate, convergent and feebly sinuate to the apex, 

 which is broadly arcuate and fully one-half as wide as the base, the latter but 

 slightly oblique, the median lobe small but prominent ; disk coarsely deeply 

 and very densely punctate, the punctures two-thirds as wide as the scutellum 

 and almost in mutual contact ; median impunctate line narrow, not attaiuing 

 the apex. Scutellum moderate, quadrate, not impressed but somewhat rugose. 

 Elytra, slightly wider and nearly four-fifths longer than the prothorax ; sides 

 behind the feebly prominent humeri slightly convergent, the apex abruptly 

 and obtusely rounded ; stria3 moderately deep, not very coarse, the intervals 

 fiat, nearly twice as wide as the grooves, the punctures moderately coarse, not 

 very dense but rugose and confused on all the intervals, the second and third 

 a little wider. Abdomen strongly, rather coarsely, somewhat closely punctured. 

 Prosternum broadly and just visibly impressed, separating the coxae by oue- 

 half of their own width. Length 3.3-3.5 mm. ; width 1.6-1.7 mm. 



Arizona. 



The form of the prothorax, with the pronotum more declivous 

 anteriorly, shows that this very distinct species should be associated 

 with transversa and its allies. In the male the abdomen is broadly 

 and feebly but distinctly impressed near the base.
