I have not been able to sec this insect and am therefore unable to in- 

 clude it in the synopsis. It is described as under : 



"Reddish brown, thorax longer than wide with fine short transverse rugae at 

 "middle and two a1 sides somewhat longer, the side- subspinose; elytra truncate and 

 "externally spinose, with the suture, basal margin, an oblique" line- from humerus to 

 "suture and a small spot at middle, whitish or luteous pubescent, or with the lines 

 "reduced to dots." 



The posterior thighs arc described as spinose by Dr. Leconte in 

 rhombifer, not in Hopri. It is a West Indian species and apparently rare 

 in collections here.

Differs from the next but slightly ; the band of thorax is however 

 always distinct, the thorax more narrowed in front, and the elytra more 

 strongly armed at tip, generally bispinose.

Reddish brown, posterior two-thirds of elytra and parts of thorax 

 often darker. This and the above have the markings fairly constant but 

 sometimes partly obliterated.

Very distinct by the characters named in the table. Dark brown 

 with sparse whitish pubescence. Chevrolat has based a new genus upon 

 its characters which, as it stands alone in our fauna, it seems unnecessary 

 to use. The clubbed antennae are partly approached by other species.

This species has been taken in great number at Key West and Indian 



River, Fla. , also in Cuba. Color reddish brown with white pubescence. 



Thorax sometimes black and white markings sometimes partly obliterated.
