NORTH AMERICAN COLEOPTERA. 19 



strise finely, moderately densely punctate ; body beneath finely and densely punc- 

 tate, a little coarser on the prosternum ; antennal groove sharply defined, not 

 wider posteriorly, the propleural triangle with the outer side twice as long as the 

 base ; mesopleurfc with few punctures at base and externally ; legs and tarsi fer- 

 ruginous. Length .36 inch ; 9 mm. 



I have in my collection a specimen which I think must be referred 

 to this species, but I do not observe the median depressions of the 

 thorax mentioned in the above description. These are, however, 

 faint in the type and are a variable quantity, so that I do not attach 

 any importance to their absence. The facies of the species is very 

 deceptive and not unlike Fornax bicohi: In addition to the charac- 

 ters given by Bonvouloir I observe that the last joint of the tarsi is 

 extremely slender and the claws very small, feebly curved and sim- 

 ple. My specimen is .42 inch ; 10.5 mm. long. 



Collected near Caiiandaigua, New York, by I'abbe de Marseul, 

 and on Long Island by Mr. Wm. Jiilichs. 



D. salens Bonv. — "This species is .so like the preceding that I hesitated a 

 long time before separating it ; so that it will be neces.sary to mention only the 

 ditferential characters. The pubescence is more silken and of a golden reddish 

 color ; the head more coar.sely, densely and roughly punctured ; the clyiieus wider 

 at base and the apex is not twice as wide ; the front is slightly impre.ssed at mid- 

 dle anteriorly ; the thorax is very nearly as long as wide, the sides slightly sinuate, 

 the punctuation coarser, denser and more rugose, the base on each side of middle 

 more depressed and with a small median gi-oove, which is interrupted, attaining 

 the middle in front ; the intervals of the strise are distinctly rugo.se tramsversely ; 

 the mesopleurte are entirely punctured with coarse impressed punctures. Length 

 .38 inch ; 9.5 mm. 



The al)ove is nearly a literal translation of Bonvouloir's remarks, 

 which I have thought advisable to repeat in order that the preceding 

 species may be more readily known. I observe, hoAvever, that the 

 second joint of the antennae is much longer than the fourth, the 

 third as long as the next two, the fourth is short, not as long as wdde, 

 joints 5 - 10 gradually very little longer, eleventh longer and acute 

 at tip. 



I am indebted to my friend Salle for the privilege of examining 

 the type of this species, collected by him in Louisiana. 



D. nitens n. sp. — Form oblong, parallel, narrowed only at apical third, color 

 black, moderately shining, the pubescence extremely short and inconsiiicuous ; 

 antennae piceous, extending slightly beyond the hind angles of the thorax, slender, 

 scarcely at all serrate, second joint as long as the fourth, third as long as the next 

 two, 4 and 5 equal, 6-8 equal, distinctly longei-, 9 and 10 equal, scarcely longer 

 than 4 and 5, eleventh one and a half times as long as the tenth ; head convex, 

 without interocular carina, moderately densely, but not roughly punctured ; cly-
