Maine, Dr. T. W. Harris: also occurs in New York. The body beneath is bright cop- 
pery, the prosternum flat, densely punctured, the mesosternum coarsely and tolerably 
densely, the feebly sulcate metasternum and middle of first ventral segment sparsely 
punctured, the latter not sulcate. 
20. D. lacustris, nigro-fusca, subsenea, thorace latitudine duplo breviore, lateribus modice dilatatis, antice 
rotundatis postice sinuatis, dense punctato, carina postica ad angulum, costisque quatuor subleevibus, externis late 
interruptis, postice utrinque late excavato, sulco dorsali profundo callo parvo medio notato, elytris dense punctatis, 
striis fortiter punctatis, interstitiis alternis spatiis paucis nitidis parum elevatis, postice longius prolongatis rotun- 
datis. Long. -66. 
Femina abdominis segmento ultimo apice rotundato. Mas latet.

Lake Superior, on Point Kewenaw. Resembles in general appearance D. punctulata, 
but the sides of the thorax are dilated, and therefore more rounded, and the elytra are con- 
siderably prolonged at the apex. The body beneath is dark coppery, coarsely and densely 
punctured, except on the metasternum and middle of the first ventral segment, where the 
punctures are less dense. The prosternum is nearly flat, the metasternum broadly 
slightly concave, the first ventral segment not sulcate. 
I am doubtful in regard to the propriety of regarding this as Kirby’s species, because he 
states that the thorax is without smooth elevations, and that the smooth spaces of the elytra 
are near the outer margin. 
21. D. bifoveata, atra, vix enea, thorace latitudine duplo latiore, lateribus dilatatis antice valde rotundatis 
postice breviter sinuatis, rude punctato, carina postica ad angulum, callis ad apicem et basin costisque duabus sub- 
leevibus, utrinque pone medium profunde excayato, sulco dorsali profundo, callo medio interrupto, elytris dense 
punctatis, striis fortiter punctatis, interstitiis alternis spatiis paucis nitidis subelevatis, postice vix prolongatis sub- 
truncatis. Long. ‘51. 
Femina abdominis segmento ultimo ventrali minute biinciso. 
One specimen, Lake Superior. Also resembles the last species, but the elytra are less 
prolonged, the thorax is more dilated on the sides. The body beneath is coarsely but not 
very densely punctured, the prosternum slightly sulcate, the mesosternum very coarsely 
punctured, the metasternum a little less punctured, broadly concave; first ventral seg- 
ment less punctured at the middle, sulcate only at the base. 
22. D. crassicollis, obscure cinereo-eenea, thorace latitudine plus duplo breviore, lateribus valde dilatatis,
