fectly with the description and figure of Olivier. It 

 should, therefore, be restored to our list. 



In a revision of Galerucini published by me (Trans. 

 x\m. Ent. Soc., xx) several years ago, several errors 

 occurred, which I now desire to correct. 



Phyllecthrus Lee. 



Antenna? dissimilar in the sexes, thickened toward the tip 3 , filiform $, 

 but 11 -jointed in both sexes. 

 Antenna' more or less yellow $ ; totally black $ . 



Thorax decidedly broader than long; elytra sparsely puuctulate. 



parallelus. 

 Thorax nearly square; elytra vaguely subsulcate and rather coarsely 

 punctured. subsulcatus. 



Antennas black 6 ; female unknown. Schioarzi. 



Antenna' similar in the sexes, filiform and black; 10-jointed S, 11-jointed 



?• 

 Small species (.10-. 15 inch.), legs more yellow. gentilis. 



Large species (.IS-. 25 inch.), legs more black. dorsalis. 



The change in the table is in the removal of dorsalis 

 from the series in which the antennas are dissimilarly 

 formed in the sexes, but with an equal number of joints, 

 to the series in which the antennas are similar in form, 

 but with unlike number of joints. 



Phyllecthrus parallelus Horn and P. subsulcatus 

 Horn, need no other comment than already published. 



Phyllecthrus dorsalis Oliv. (atriventris Say.). To 

 Mr. E. A. Schwarz I am indebted for having my atten- 

 tion called to the true male of this species and to my error 

 in a description of its supposed male, which will be ex- 

 plained further on. 



Male.— Antenna? slender, fully as long as the entire body, ten-jointed, 

 second joint very small, apparently connate with the base of third joint; 

 joints 3-9 about equal in length, tenth longer and obliquely narrowed at 

 apex. Middle tibia? emarginate on the inner side near apex.
