HT, Guexi Muls. 687. 
I have compared my specimens with Randall’s type, the only one remaining 
in his collection at the time I examined it. My specimens agree perfectly with 
YW ulsant’s description of H. Guexi.

Southern States. Broadly oval, convex, shining black. Head sparsely punc- 
tured black, with yellow palpi. Thorax very short, marked with a few distinct 
punctures, base rounded, finely margined, sides rounded, posterior angles

Georgia, and Missouri Territory. Very similar to the preceding, but besides 
the differences in color the thorax is less distinctly punctured, and the posterior 
angles are more rounded. A specimen from New York has the head and tho- 
rax entirely black, but the feet are yellow. It is probably the female of this 
species.

New Orleans, one specimen, Mr. Guex. Oval, less convex than usual, shining, 
finely and densely punctured, and very finely pubescent. Head and organs of the 
mouth yellow. Thorax narrowed in front, base slightly sinuous, finely margined, 
black, sides with a yellow margin, which is wider in front. Elytra forming a 
very distinct angle with the sides of the thorax, black, with a large transverse 
spot, a posterior band and the apex yellow ; the spot is ‘oblique and extends from 
just below the humerus to the middle of the elytra, ending near the suture; the 
band is placed at the second third of the elytra, is sinuate on each side, and at the 
sides and suture is confluent with the yellow apical margin, so that on each side 
a transverse black spot is included. Under surface black, venter testaceous at 
the sides and apex; feet yellow.

gray hair. Thorax narrowed in front, slightly rounded on the sides, base not 
sinuate, distinctly margined in the middle. Elytra with a large oblique orange 
colored spot before the middle, and another rounded, somewhat transverse one 
behind the middle extending nearly to the sides and to the suture. Under sur-
