Mr. Waterhouse on a new species of Lophotus. 329 



XXXIX. — Description of a new Species of the genus Lo- 

 photus, from the collection of Charles Darwin, Esq. By 

 G. 11. Waterhouse, Esq., Curator to the Museum of the 

 Zoological Society, S^c. ^c. 



The genus Lophotus, founded by Schoenherr* upon an 

 insect from Chile, is placed by that author in his family Cleo- 

 nides, and in the apterous section of that family. But one 

 species of Lophotus was known to him at the time of the 

 publication of his second volume ; he must now however be 

 acquainted with two species, the Rev. F. W. Hope ha\ing 

 sent him two from his own collection. One of these is de- 

 scribed and figured by Mr. Hope in the ^Transactions of the 

 Entomological Society,^ under the name of Loph. nodipennis ; 

 to the other he applies the name trifasciatus — this, however, 

 I believe to be the same as Schoenherr's species. Mr. Hope 

 also refers the Curculio Vitulus of Fabricius to the same 

 genus : there are therefore three species of Lophotus known ; 

 and as these are now before me, together with the new species 

 I am about to describe, I will endeavour to point out their 

 chief distinguishing characters.
