smoother at middle. Tliorax transverse, regularly convex, sides arcuate at 

 middle, slightly oblique in front and faintly sinuate jiosteriorly, the angles dis- 

 tinct, hut not acute, basal marginal line M'anting, disc punctate, but not closely, 

 a faint impression near the base opposite the 4th elytral stria. Elytra striate, 10th 

 stria entirely wanting, strife nearly obliterated at apex, finely punctate, intervals 

 flat, sparsely and indistinctly xnirictate. Body beneath piceons, opaque, meta- 

 sternal area shining, sparsely punctate. Legs rufo-piceous. Prosternum finely 

 carinate, mesosternal elevation very narrowly fusiform. Length .08 — .10 inch. ; 

 2—2.5 mm. 



In some of the specimens there is a faint ante-sciitellar impression 

 at the base of the thorax, but it is variable in extent and constancy. 

 There seems to be very little variation, except that due to less ma- 

 turity. One specimen in my cabinet has the first and second strise 

 united at base by an arch as in some fimbriatus. 



Specimens have been collected by Mr. Ulke at Piney Point, Md. 

 Two others from California are in my cabinet. In Euro{)e it is 

 widely distributed on the Atlantic and Mediterranean shores*. 



C. iinipiinctatus Linn. — Oval, slightly oblong, feebly convex, piceous 

 black, shining, sides of thorax pale; elytra reddish yellow, with an oval, sutural, 

 piceous spot behind the middle, extending narrowly along the suture to apex. 

 Antennse testaceous, club fuscous, palpi testaceous, last joint piceous. Head 

 moderately closely punctate. Thorax transverse, sides rather strongly arcuate 

 posteriorly, oblique in front, basal marginal line distinct, except at middle; basal 

 impressions very vaguely indicated, surface moderately closely punctate, less so 

 at the sides. Elytra ten striate, strife punctate, but not closely, a little less 

 deeply impressed at apex, intervals flat, not closely punctulate, the eighth narrow 

 and with a single row of punctures. Body beneath black, opaque, metasternal 

 area shining, sparsely punctate. Prosternum distinctly carinate, mesosternal 

 elevation narrow, closely punctate. Legs rufo-testaceous. Length .12 inch. ; 

 3 mm. 



This species shows very little variation. The common piceous spot 

 may vary in size and color, or the pale margin of the thorax may 

 be greater or less. From its coloration this sjoecies may be very 

 readily recognized. 



Occurs in our fauna in Canada, New England and Middle States, 

 westward to Illinois. It is widely distributed in Europe extending 

 eastward to Siberia. 



C quisqiiilius Linn. — Oval, moderately convex, piceous, shining, sides 

 of thorax pale, elytra variable from dark rufo-testaceous to nearly piceous. An- 

 tennse and palpi piceous. Head moderately closely, but not coarsely punctate. 

 Thorax transverse, the sides regularly arcuately narrowed from base to apex, the 

 basal marginal line distinct at outer third, ante-basal impressions faintly distinct 

 opposite the fourth stria, surface moderately closely punctate, less closely at the 

 sides. Elytra ten-striate, strise rather closely punctate, those of the disc indis-
