angles. Male not at hand. Length 12.7-14.5 mm.; width 3.8-4.8 

 mm. California (Sacramento Co.) californicum n. sp. 



Impunctate thoracic vitta more or less broad, entire, very sharply defined 

 and distinct; pubescence rather less dense, the two darker transverse 

 elytral bands generally distinct, feebler and indistinct in boreale; 

 abdomen mottled red and black as a rule, sometimes becoming 

 wholly black 3 



3 Femora very stout, half as broad as the thoracic width; body stout; 

 head well developed, the punctures perforate, moderate in size and 

 well separated; eyes separated by two and one-half times their own 

 width; antennae extending fully to the base of the prothorax, of the 

 usual structure; prothorax fully as wide as long, the punctures like 

 those of the head but smaller, fully as sparse, not concealed by the 

 vestitute; elytra subparallel, almost twice as long as wide, very 

 much wider than the prothorax as usual, the ridges rather feebler 

 than in any other species, black, the testaceous spots small; abdomen 

 sparsely and not strongly punctured, sparsely pubescent in the 

 usual clusters, testaceous, the median line and apical margin of all 

 the segments black; segments three to five diminishing rapidly in 

 length, the truncate apex of the fifth scarcely more than half as wide 

 as the base. Length (cf ) 16.0 mm.; width 5.2 mm. Massachusetts 

 (Medford) crassipes n. sp. 



Femora of the usual thickness, much less than half as thick as the thoracic 

 width 4 



4 Antennae unusually small, the head much less developed than usual; 

 body small in size, colored and pubescent as usual; head relatively 

 coarsely and irregularly punctate, with an admixture of smaller 

 punctures, the antennae not as long as the head and prothorax, the 

 latter formed as usual, the sculpture coarser and more irregular than 

 in the preceding, though nowhere very close; elytra nearly as in 

 the preceding but with stronger ridges and coarser sculpture; ab- 

 domen finely and remotely punctate, black, each segment testaceous 

 except at the middle, base and apex, the fifth trapezoidal and a 

 little longer than the fourth. Length (9 ) 11.5 mm.; width 3.5 mm. 



Massachusetts (Maiden) parvicorne n. sp. 



Antennae and head of the usual development 5 



5 Apex of the fifth male ventral rectilinearly truncate and unusually 

 broad, much more than half as wide as the base. Body in form and 

 coloration nearly as in the preceding, the cephalic punctures rather 

 coarse, perforate as usual and well separated; eyes separated by 

 nearly three times their own width in the male; prothorax as usual, 

 except that the apical is relatively less than the basal width, the 

 sculpture close and subrugose, the median smooth stripe narrower 

 than in any other except californicum though even; elytra confusedly 

 mottled, the black rather predominating, the ridges strong and the 

 sculpture very coarse, dense and deep; abdomen deep black through- 

 out in the type, the last three segments diminishing gradually though 

 very slowly in length. Length (cf) 12.5 mm.; width 4.3 mm. Wis- 

 consin (Bayfield), Wickham boreale n. sp.
