among British Agrioninse, and the striking contrast subsisting 

 between our primitive females and the males brings this species 

 into line with other members of the subfamily, and especially 

 with the allied species, I. pumilio.

BIBLIOGRAPHICAL AND NOMENCLATORIAL NOTES ON 

 THE HEMIPTERA. No. 2.* 



By G. W. Kirkaldy. 



With great regret I feel it advisable to relinquish the sugges- 

 tive and characteristic ordinal name " Rhynchota " for the prior 

 " Hemiptera." I am by no means convinced of the necessity or 

 advisability of enforcing priority in names above family rank ; 

 indeed in some cases it would appear inexpedient, if not im- 

 possible, to do so ; but in such a case as the above, where a prior 

 term has been in frequent, though partial, usage, it seems better 

 to adopt it. 



Hemiptera is a Linnean term, comprising in 1758 not only 

 the "bugs" but also the Dermaptera (later called Orthoptera) ; 

 Geoffrey in 1762 restricted " Hemiptera" to the bugs, placing the 

 remainder of the old Linnean assemblage among the Coleoptera. 



The following shows the synonymy according to priority ; I 

 would be sorry, however, to have to adopt " Siphonata " instead 

 of " Homoptera." 



Order : Hemiptera, Linne, 1758 (part) ; Geoffroy, 1762. 

 type Cimex. 

 = Ekytigota, Fabricius, 1775 -= Rhynchota, Burmeister, 

 1835. 



Suborder 1 : Heteroptera, Latreille, 1802, type Cimex. 

 =- Dermaptera, Retzius, 1783 (nee De (jeer, 1773). 

 = Hemiptera, Westwood, 1838. 



2. Siphonata, Retzius, 1783, type Cicada. 

 = Homoptera, Latreille, 1802. 



I have recently been led to look into the nomenclature of the 

 Sternorrhynchous forms, &c., and find that these researches do 

 not altogether confirm the changes of recent years ; in par- 

 ticular it is to be regretted that Mrs. Fernald, in her recently 

 published ' Catalogue of the Coccida3,'t — a work for which, as a 

 whole, one can find nothing to say but admiring thankfulness for 

 the labour devoted to it during so many years, — it is to be regretted 

 that the typical genus Coccus has been grievously misapplied.
