CHANGE OF NAMES IN COLEOPTERA. 



By Chas. Schaeffer, Brooklyn Museum, Brooklyn, N. Y. '^ 



Mr. Julius Weise recently called to my attention that a few of 

 the new names in my paper on species of the family Chryso- 

 melidse in Journal N. Y. Ent. Soc, XXVII, pp. 307-340, have 

 already been used. I propose, therefore, the following changes : 



Donacia assimilis Lacordaire^.Do-waa'a g-labrata Schfifr. 

 Journ. N. Y. Ent. Soc, Vol. XXVII, p. 313. 



The name glabrata is preoccupied by Solsky for a Silician 

 species, however, studying lately very closely the descriptions of 

 the species of Donacia described by Lacordaire from North 

 America I have very little doubt that my glabrata is the same as 

 ussimilis; The latter is wrongly made a synonym of palmata 

 with which it cannot be associated, the deep, large, median im- 

 pression and sculpture of prothorax, the shining, glabrous sur- 

 face and the unarmed posterior femora in both sexes are char- 

 acters entirely foreign to palmata. Donacia glabrata is the only 

 described species which fits the description of assimilis best. 



Melasomida new name. 



Fseudolina Schffr. Journ. N. Y. Ent. Soc, Vol. XXVII, p. 



.330. 



Pseudolina is already in use by Jacoby for an East Indian 

 ^enus. 



Colaspis weisei new name. 



Colaspis subcenea Schffr. Journ. N. Y. Ent. Soc, Vol. XXVII, 

 p. 328. 



There is already a species described as Colaspis subcenea by 

 Jacoby from Guatemala.
