served with 9-joiiited antennie. The peculiar abdominal characters 

 of the male leave no doubt that this is merely an accident. 



With this species I have united Burinekteri Lee, founded on smaller 

 specimens. The name was given under the supposition that Bur- 

 meister had incorrectly identified longitarsis Say, but I think that 

 any one who will read his description will be fully satisfied that Bur- 

 meister had a genuine longitarsis before him. 



Occurs from Canada to Florida and Texas. 



Group V, longitarsis. 



This group contains two species which agree in having the an- 

 tenuse 9-jointed, the palpi fusiform, distinctly impressed. The spurs 

 of the male hind tibiie are— the inner very short and fixed, the outer 

 long and slender. The claws have a small intramedian tooth. 



The following table will assist in the separation of the species : 



Clypeus deeply emarginate ; form elongate cylindrical, pale yellowish testaceous, 

 head fuscous or piceous 13. loiiji^ifarsis. 



Clypeus entire; form ol^long. slightly broader behind, rufotestaceous, Iiead 

 darker 14. Clemens. 



Were it necessary, by the presence of other species, these two 

 might form the types of distinct groups. 



The first species occurs in the Mississippi Valley, the second in 

 Florida and Texas, and has been erroneously determined by Dr. 

 LeConte as dispar Burm. 



13. Jj. longitarsis Say. — Slender, elongate, cylindrical, pale yellowish tes- 

 taceous, front fuscous or piceous; surface moderately shining. (;iypcus concave, 

 deeply eniarginate, surface shining, coarsely very sparsely punctured, front 

 coarsely densely punctured. Thorax short, transverse, strongly arcuate in front, 

 slightly sinuate, margin entire, fimbriate in front, surface somewhat irregular, 

 the punctures coarse not deep, rather closely ])li)ced. Elytra coarsely punctured, 

 the punctures rather shallow, sparser near the apex, the discal costse very feeble, 

 the submarginal moderately well defined. Pygidium % with coarse shallow 

 punctures, those of the 9 finer and more sparse near the apex. Metasternum 

 closely, but indistinctly punctate, the hairs moderate in length but sparse. Ab- 

 domen sparsely indistinctly punctate at the sides, the last two segments more 

 coarsely punctured. Last joint of maxillary palpi sliort, fusiform, very distinctly 

 impressed. Claws feebly curved % and with a small acute tooth near the base, 

 the 9 claw more arcuate, the tooth stronger and median. Length .41 — .52 inch ; 

 10.5— 13 mm. 



Male. — Antennal club a little longer than the stem. Abdomen 

 slightly flattened at middle, the last segment irregularly concave. 

 Inner sjuir of hind tibia male short, the outer lung and slender.
