Black, or partlv rufous. EUual bands fdllowing the same arranj^e- 

 ment as in Mirrac/v/us bul com{)osed of sliort hairs and narrow and the 

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

 sometimes confusetl in collections with the prccedinc; but the s})ine of 3rd 

 antenna! joint at once ilistin,<;uisiics it. The 4lh and 5th joints sometimes 

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

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

 (hsappcars 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- 

 tlually 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 arrangetl as follows : two longituchnal 

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

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

 third except the extreme tip. The lounded eye of.tiii^ species has been 

 described before 



EUDERCES, Lfc. 



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

 bands of the elytra. They may be thus separated : 

 SYXOPSIS OF EUDERCES. 

 Klytra \vitli one ol)iit]uc ivory fascia ; thorax striate. 



F^yc nearly divided, the two parts connected by a thin correous line ; prothora.x 



uniformly rounded at the sides picipes. 



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



mart^in and subangulate at sides pini. 



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



completely divided Reichei. 



Klytra with two transverse parallel ivory fascia? parallelus.
