Black, or partly rufous. Elytra] bands following the same arrange- 

 ment as iii Microclyius but composed of short hairs and narrow and the 

 short transverse band more or less united with the next. The insect is 

 sometimes confused in collections with the preceding but the spine of 3rd 

 antennal joint at once distinguishes it. The 4th and 5th joints sometimes 

 bear shorter spines also. The basal elevation of the elytra is verv con- 

 spicuous, rising abruptly in front and descending gradually behind until it 

 disappears near the middle of the outer margin.

Black, or partly rufous, marked with lines of white pubescence. Legs 

 nearly testaceous. The elevation of the elytra is well marked, rising gra- 

 dually in front and running obliquely as in Cyrtophorus but terminated 

 sharply behind and the arrangement of the bands causes a deceptive appear- 

 ance ol a channel immediately behind it. The white pubescence is almost 

 silver in color and brightness and arranged as follows : two longitudinal 

 lines on the thorax, obliterated in front, two oblique parallel lines on the 

 elytra, close together and immediately behind the elevation, ami the apical 

 third except the extreme tip. The rounded eye of this species has been 

 described before 



EUDERCES, Lee. 



The four species of this genus are very easilv known by the ivory 

 bands of the elytra. They may be thus separated : 



SYNOl 'SIS OF E I 'DER C 'E S. 

 Elytra with one oblique ivory fascia ; thorax striate. 



Eye nearly divided, the two parts connected by a thin correous line ; prothorax 



uniformly rounded at the sides picipes. 



Eye completely divided ; prothorax distinctly depressed each side near the anterior 



margin and subangulate at sides pini. 



Elytra with one exactly transverse ivory fascia ; prothorax punctate, not striate ; eye 



completely divided Reichei. 



Elytra with two transverse parallel ivory fascia? parallelus.
