ing black areas, the slightly depressed cupreous areolae small, well de- 

 fined, finely and closely punctate; prolongation cupreous; under sur- 

 face and femora coarsely, closely and rugosely punctate, the axial line 

 smoother and impressed as usual, the fifth ventral ( $ ) binigrocostulate 

 medially, the median tooth of the apical sinus acute but broad at base, 

 triangular. Length (9) 16.0 mm.; width 5.4 mm. Massachusetts. 



abrupta n. sp. 



Series of fine punctures, which are rather remotely spaced, rather distinct 

 on the elytra except laterally, the series unimpressed 5 



5 — Body short and rather stout, convex, only moderately shining, cupreous, 

 with obscure or blackish elevations, the under surface dark cupreous; 

 head coarsely, densely punctate, canaliculate posteriorly, with numer- 

 ous longitudinal rugae centrally, the eyes moderate in size but very con- 

 vex and extremely prominent, deep black in the type; prothorax fully 

 three-fourths wider than long, the sides parallel and deeply sinuate for 

 a little more than a third, there broadly but very sharply angulate and 

 thence strongly converging and straight to the apex; surface broadly 

 impressed and more closely punctate throughout the length on the median 

 line, with a large basal impression containing two deep punctures, 

 coarsely, deeply, subconfluently punctate and with scattered irregular 

 callous spots laterally, feebly impressed sublaterally behind the middle; 

 elytra nearly as in the preceding but shorter, only a little more than 

 twice as long as wide, the surface uneven, irregularly sculptured, very 

 densely laterally, the raised spots feebler, the cupreous areola? almost 

 similar, the prolongation shorter and broader; under surface nearly 

 similar, the black ridges of the fifth ventral feebler and less approxi- 

 mate. Length (c^) 15.0 mm.; width 5.2 mm. New Hampshire 

 (Hampton) biangulata n. sp. 



Body elongate-oval, convex, shining, dull cupreous, the elytra obscure 

 greenish throughout though varied by feeble subamescent reflections, 

 the prolongation not different in color; under surface dark cupreous; 

 head coarsely, unevenly rugose and punctate, with a depression before 

 the central callus; eyes rather well developed, somewhat prominent; 

 prothorax barely three-fifths wider than long, the sides subangularly 

 prominent slightly behind the middle, thence subparallel and feebly 

 sinuate to the base and converging and broadly arcuate to the apex; 

 surface canaliculate and densely punctured before the middle and 

 simply more closely punctate posteriorly on the median fine, the basal 

 pit large, deep and single, the sculpture otherwise nearly as in the 

 preceding; elytra aberrant, similar to abrupta in form though more 

 gradually attenuate, but almost uniformly punctate, without densely 

 punctate cupreous areolae and with the raised spots feeble, small and 

 few in number; punctured series unimpressed and scarcely traceable, 

 except near the suture; under surface nearly as in abrupta. Length 

 (9) 17.0 mm.; width 5.8 mm. Massachusetts iiiflatula n. sp. 



6 — Form elongate-oval, convex, rather shining, cupreous with the eleva- 

 tions black, brighter cupreous beneath; head coarsely, very densely 

 but subevenly punctato- rugose, the eyes moderately convex and rather
