This species should be easily recognized by the size and char- 

 acters of the table. The discal vitta {fide Lee. ) is abbreviated in 

 front.

 This species has been known in collections generally under 

 Randall's name vittiger, but Say's date is tifteen years earlier. The 

 differences between the two have been summarized by Randall and 

 Bland as follows: vittiger, ground color black, third joint of an- 

 tennae longer than fifth; trivittatus, ground color reddish yellow, 

 third joint of antennae about equal to fifth. Both characters are 

 found to vary in other species, ^\\d fide Dr. Horn there is only one 

 species.

This species resembles vestitus in the arrangement of the elytral 

 pubescence, but differs by the black discal lines, between which the 

 pubescence is very abundant and often golden in color, making it a 

 very pretty insect. The discoidal vitta is narrower than in vittiger, 

 and does not descend to the inflexed portion.

 Rufous, elytra and tarsi darker. The tips of the elytra are ob- 

 liquely truncate, and the angles produced, subbidentate.

Dr. LeConte's description says " differs from all the other species 

 before me by the less deeply constricted prothorax and more ob- 

 tusely rounded lateral tubercles; the eyes are smaller than usual and 

 finely granulated, but more con\'ex than in vestitus, with which it 

 agrees in this character; the third and fifth joints of the antenme are 

 equal, and the fourth joint is two-thirds as long. The pubescence 

 is extremely short and fine."
