It is perhaps doubtful whether this Blmuld In- separated from tho 

 pnoediDg. It differs, however, in having the thorax and elytra of 

 i uniform clour, the antennas are much more Btrongly dentate, the 

 thorax does qo! present the same roughness in front, and tho trans- 

 its of the interstices of the elytra are further apart, tho 

 spaces divided l>y them being nearly squares, even in the lateral 



interstice. 



Xylobanus foveatus. 



(Plate X. fig. 2.) 



This species differs from the preceding in having the thorax and 

 elytra of a dull yellowish red. The antenna) are very strongly 

 dentate ; the thorax has the posterior angles not diverging, and the 

 mesial posterior areolet, instead of terminating in the middle of the 

 disk, extends much more forward.

This species resembles X. foveatus, but is broader, the posterior 

 angles of the thorax are acute, and the transverse costae of the in- 

 terstices of the elytra are twice as close together, the space between 

 the costae being about equal to the thickness of the costae.
