 Bost. Journ. V., p. 40, pi. 1, fig. 4. 



Slightly longer and more depressed than earolinus. Thorax smooth at 

 middle, sparsely punctured at the sides, marginal stria entire. Elytra 

 with three entire dorsal striae, fourth apical, extending to middle some- 

 times very nearly entire, fifth short apical, sutural feeble equal to the 

 fifth. Propygidium coarsely, but very sparsely punctured, pygidium 

 coarsely puuetured at base, more finely and sparsely at apex. Anterior 

 tibia? 4-dentate, middle 3-, apical 2-spinous. Length .10-. 12 inch ; 

 2.5-3 mm. 



Occurs abundantly over nearly our entire territory. The specimens 

 from California all differ from those of the Atlantic region by the entire 

 obliteration of the frontal stria. As there are no other discoverable 

 points of difference, I prefer to regard them merely as varieties. 



H. aurelianus. n. sp. 



Closely allied to Lecontii, but more depressed and differing as follows : 



Thorax not punctured at the sides. Elytra with three entire dorsals, 

 fourth very short, apical, fifth obsolete, sutural entirely absent. Length 

 .12 inch ; 3 mm. 



Kindly presented to Dr. Leconte, by M. Salle, who received it from 

 the neighborhood of New Orleans, Louisiana. 



The above three species have the mesosternal stria entire. 



H. parallelus, Say. Journ. Acad., 1825, p. 42 ; Lee. Bost. Journ. V., 

 p. 40, pi. 1, fig. 5 ; Mars. Mon., 1852, p. 264, pi. 7, fig. 9. 



Moderately elongate, sub- cylindrical. Thorax sparsely and evenly 

 punctured. Elytra with the five dorsal and sutural stria? entire, and 

 with a short basal humeral stria. Pygidium and propygidium very 

 coarsely, but sparsely punctured. Mesosternal marginal stria entire. 

 Anterior tibia? 4-dentate, apical tooth bifid, middle tibia? 4-, posterior 

 2-spinous. Length .10 inch ; 2.5 mm. 



Occurs in Georgia, South Carolina and Florida. 



H. sequus, Lee. New Species, 18G3, p. 61 ; frontalis, || Say. Journ. 

 Acad., 1825, p. 43. 



Closely allied to the preceding, but more depressed. Fifth dorsal stria 

 always abbreviated at base. Mesosternal stria broadly interrupted at 

 middle. Middle tibia? 3-spinous. Length .08 inch ; 2 mm. 



Occurs in Georgia. 



H. coarctatus, Lee. Bost. Journ. V., p. 41, pi. 1, fig. 6 ; Mars. Mon., 

 1853, p. 282. pi. 7, fig. 25. 



Elongate parallel, cylindrical. Thorax evenly but not densely punc- 

 tured. Elytra with four entire dorsal stria?, fifth three-fourths and 

 sutural cwo-thirds the length of the elytra, a very short basal humeral. 

 Propygidium coarsely, but sparsely .punctured, pygidium finely, and 

 very nearly smooth at apex. Mesosternal stria entire. Length .10-. 12 

 inch ; 2.5-3 mm.
