318 MEMOIRS ON THE COLEOPTERA 



than in the preceding, very slender; prothorax barely one-half wider 

 than long, feebly trapezoidal, the apex but little narrowed, the dark 

 maculation normally forming four very large, more or less confluent 

 spots, the depression near the basal angles also dark; elytra more 

 elongate, much more than twice as long as wide, subparallel, very 

 gradually and arcuately narrowing behind the middle to the broadly 

 obtuse and rounded apices, which are relatively very much broader 

 than in camis, the punctures fine, sparse; dark maculation having 

 nearly the same form and extent as in the following species, but 

 variegated and more comminuted with ashy hairs; last dorsal seg- 

 ment (9 ) projecting distinctly behind the elytra, flat, with its apex 

 rounded, but less rapidly cuneate than in caniis. Length (cf 9 ) 

 5.7-7.2 mm.; width 1.7-2.2 mm. Atlantic regions, [angnlatus Lee.].

4 Form elongate, rather depressed; color dark umber, clothed rather 

 densely with extremely short fusco-cinereous pubescence, variegated 

 with darker linear spots, the dark areas of the elytra solid and not 

 partially ashy as they are in the preceding; antennae dark luteo- 

 testaceous; prothorax shorter, more or less trapezoidal, with feebly 

 undulating sides, rounding apically, two-thirds to three-fourths 

 wider than long, very indefinitely variegated; elytra subparallel, 

 the sides gradually rounding and converging posteriorly to the 

 strongly rounded apices, much more than twice as long as wide, 

 the spots large, one oblique from the middle of the base toward the 

 suture behind the scutellum, one lateral and irregular from the 

 humerus, expanding posteriorly irregularly, this area sometimes 

 attaining the suture behind the middle, thence narrowing to the 

 external margin near the apex; last dorsal (9 ) narrowly parabolic, 

 not extending behind the elytra. Length (cf 9 ) 6.2-7.2 mm.; 

 width 1.8-2.2 mm. New York, Indiana and Ontario, [pictus Lee.]. 



symmetricus Hald. 



Form elongate, feebly flattened above, pale rufo-testaceous in color 

 throughout and with the vestiture so minute and fusco-cinereous as 

 to be scarcely visible; head deeply indented; antennae slender, con- 

 colorous, three-fourths longer than the body (cf), nearly similar 

 ( 9 ) ; prothorax trapezoidal, three-fifths wider than long, the spine 

 much before the base, barely behind basal third, strong and sharply 

 pointed; surface feebly impressed along the base laterally, finely, 

 sparsely punctate, almost impunctate anteriorly, the vestiture not 

 at all concealing the surface, not variegated; elytra distinctly cunei- 

 form (cf ) , broader and nearly parallel ( 9 ) , the sides broadly arcuate, 

 slightly more converging posteriorly to the narrowly and trans- 

 versely subtruncate apices, the angles rounded; surface convex along 

 the sides above the flanks, flat discally, with a large broad and feeble 

 convexity near the base of each and nearly obsolete in the female, 

 the punctures strong, moderately close, becoming wholly obsolete 

 at apex; vestiture not at all concealing the surface, uniform, there 

 being only an easily denuded minute discal spot of ashy hairs at 

 basal fifth and a feeble oblique ashy discal streak near apical fourth; 

 color nearly uniform but becoming gradually infuscate posteriorly;
