ON THE NOMENCLATURE OF THE GENERA OF THE 



HEMIPTERA. 



By G. W. Kikkaldy. 



(Part I. 1758-1843, concluded from vol. xxxvi. p. 233.) 



The alterations necessitated by finding that the date of 

 publication of the hemipterous part of the ' Voyage of the 

 Coquille ' was 1838 instead of 1830 (see ' Entomologist,' xxxv. 

 p. 316), are now made, as well as> few others caused by further 

 investigation. To rendei^iore complete the generic nomencla- 

 ture of the Hemiptera as l^hole, the genera of the Sternorhynchi 

 are added ; so that all the genera of the Hemiptera, from 1758- 

 1843, are, it is believed, now recorded.
