298 GEO. H. HORN. 



founded with any of the forms allied to hcemorrhoidalis, as these have 

 the metasternal area continued by an oblique line. The entire an- 

 tennae, including the club, are pale rufo-testaceous and will distin- 

 guish it from any species with which it could, by any possibility, be 

 confounded. 



Occurs at Grimsby, Canada (Pettit), and southward to Pennsyl- 

 vania (Dietz). 



C aduinbratiis Maun. — Oval, moderately convex, variable in color from 

 l)iceo-testaceous to piceous. but with the sides of thorax and elytral apex indefi- 

 nitely paler. Palpi and antennae piceo-testaceous, the latter with darker club. 

 Head moderately, coarsely, not closely punctate, smoother at sides and apex. 

 Thorax with sides a little more arcuate in front of the bind angles, basal mar- 

 ginal line wanting, ante-basal impressions very indistinct, disc moderately punc- 

 tate, punctures finer in front and almost obsolete at the sides. Elytra striate, 

 the tenth obsolete, strise deeper at sides and apex, those of the disc scarcely 

 visibly punctate, those at sides distinctly so, intervals of the disc almost abso- 

 lutely smooth, those at sides very indistinctly punctate. Body beneath piceoirs, 

 opaque; metasternal area shining, punctate. Prosternuni distinctly carinate, 

 mesosternal elevation very narrow, but with a distinctly punctate edge. Legs 

 rufo-testaceous. Length .08 — .10 inch.; 2 — 2.5 mm. 



This species in its variation resembles several species, notably 

 lateralis and fulvlpennls, but may be at once known from all of them 

 by the almost entire absence of interstrial punctuation. 



The color varies greatly, as indicated, and Mannerheim describes 

 it from ferruginous to fusco-piceous. In the curve of the sides of 

 the thorax it resembles unipundatus. 



Occurs from Alaska southward to Vancouver and Washington. 



<'. variegatus Sharp. — Oval, convex, moderately shining, above testaceous, 

 head piceous with a vertical yellow spot, thorax with a broad, median, piceous 

 space, a spot on eacii side in front, these often confluent; elytra with a short 

 piceous stripe at humerus below the umbone. Antennse testaceous, club piceous, 

 jialpi testaceous. Head shining, moderately closely, but not coarsely punctate. 

 Thorax transverse, the sides regularly arcuate from base to apex, disc regularly 

 convex, a faint trace of an impression near the base opposite the fourth elytral 

 stria, basal marginal line absent, surface moderately, coarsely and closely punc- 

 tate, smoother near the sides. Elytra finely striate, more deeply near the apex, 

 these faintly and distantly punctulate on the disc, but much more distinctly 

 punctate at the sides, tenth stria nearly ab.sent, intervals moderately closely 

 punctate, except near apex, the eighth interval narrower, and with but a single 

 row of punctures. Body beneath piceous opaque, abdomen sometimes much 

 paler, metasternal area shining, spai-sely punctulate. Prosternuni feebly carinate, 

 mesosternal elevation linear. Legs pale rufo-testaceous. Length .08 — .10 inch.; 

 2—2.5 mm. 



This species seems very consistent in color from my series, and
