C inariiins Thorns. — Oval, moderately convex, piceons black, shining ; 

 sides of thorax bordered with pale, elytra with yellowish testaceous space, well 

 defined, extending along the side very nearly to the humeral angles. Antennse 

 piceo-testaceous, club darker, palpi piceo-testaceous. Head moderately punctate, 

 not very closely. Thorax transverse, sides regularly narrowed from base to apex, 

 basal marginal line wanting, lateral ante-basal impressions small, puuctiform, 

 surface rather more coarsely and closely punctured than the head, sparser toward 

 the sides and a little finer in front. Elytra ten-striate, stri?e punctate and in- 

 distinct at apex; intervals flat, closely punctate, more sparsely near apex and 

 coarser at the sides; epipleurse piceo-rufous. Body beneath opaque black, meta- 

 sternal area shining, punctate. Prosternum distinctly carinate; mesosternal 

 elevation very narrowly lanceolate. Legs piceo-rufous, the femora darker. 

 Length .10— .12 inch. ; 2.5—3 mm. 



This species closely resembles prcetextatn^, and would readily be 

 mistaken for it. The apical pale space is equally sharply defined in 

 both species and in prcetextatus always reaches the humeral angles, 

 but in the present species is nearly always a little shorter. In the 

 larger number of specimens the lateral pale border is nari'ow and 

 dilates near the apex into the apical space, but in prcpiextatus the 

 border is broad and becomes rapidly broader about one-third from 

 the base. From this it will be seen that our native species has a 

 much larger extent of pale area. It will be observed in prcetextatus 

 that the palpi and antennae are pale, wdiile both are piceous in mari- 

 tiinus. In prceiextatiis the striae are deeper and more coarsely punc- 

 tate and more distinct at apex, while in maritbniis the striae are faint 

 at apex, and at the sides the interstrial punctures are nearly as 

 coarse as those of the strire. 



Occurs in British Columbia at Lake Lahache, extending eastward 

 to Dakota. The species is widely distributed in the north of Europe 

 and Asia. 



C. falvipennis Mann. — Oval, moderately convex, piceous black, shining, 

 sides of thorax pale, elytra brownish or piceo-testaceous, sides and apex some- 

 what paler. Palpi and antenuse piceous, the latter with a darker club. Head 

 rather coarsely and moderately closely punctate. Thorax transverse, sides regu- 

 larly arcuate, punctured similarly to the head, basal marginal line wanting, 

 lateral ante-basal impressions very indistinct. Elytra ten-striate, the tenth 

 stria represented by a row of punctures, strife moderately deeply impressed even 

 to apex, rather closely punctate and more coarsely at the sides, intervals flat, 

 closely punctate on the disc near base, but more sparsely at apex and sides. 

 Body beneath black, opaque; metasternal area shining, sparsely punctate. Pro- 

 sternum distinctly carinate, metasternal elevation linear. Legs rufous. Length 

 .10— .12 inch. ; 2.5—3 mm. 



This species bears a strong superficial resemblance to quisqallms, 

 hcBmorrhoidalis and lateralis. From the first it is known by the ab-
