ally behind the middle than in X. porcata), but the antennal club 

 does not differ notably from that of X. porcata. The ventral seg- 

 ments (of the example before me) are nitid throughout, and have a 

 double system of puncturation (except on the broad riband-like 

 band which forms the apical portion of the anterior four segments) 

 consisting of a very line, even, close puncturation, among which 

 much coarser and somewhat squamose punctures are rather evenly 

 but not closely mingled. The apical margin of the hfth ventral 

 segment is very feebly bisinuate. The femora do not differ notice- 

 ably from those of X. porcata; the anterior and intermediate 

 tibi?e are arched, tlie hind tibiae straight.

A very remarkable species, and very distinct from all previously 

 described. The elytra gradually and gently increase in width 

 from the base hindward to about the middle, and then dilate 

 almost suddenly to half again the width of their base. In the 

 two examples before me (probably of the same sex) the ventral 

 segments are somewhat closely and by no means finely squamose- 

 punctulate, with some much finer puncturation intermingled, the 

 puncturation being finer, closer, and less squamose about the 

 middle (and especially near the apex) of the intermediate three 

 segments. The apical margin of the fifth ventral segment is sub- 

 truncate and scarcely bisinuate. The front and intermediate 

 tibi?e are moderately arched, the hind tibias straight. Of the 

 elytral interstices all except the first and fifth are more or less 

 carinate behind. The interstices are near the base very much 

 narrower than the individual punctures in the rows.
