ART. 3 OKTHOPTEROID INSECTS FROM JAVA — CAUDELIi 31 



London and was found to be a half-grown nymph with the wings not 

 yet developed, a condition so obvious as to very surely have been 

 recognized by Walker. However, no indication of such immaturity 

 is to be found in his description, and this is not a unique case of this 

 sort of misleading element in the works of that most careless of 

 writers. Whether lutescens is a distinct species or a synonym of ensi- 

 fer is a matter of some doubt, but probably the latter. 



The fact that Lesina ensifer and lutescens have the anterior and 

 intermediate femora spined both above and below while the species 

 described by Brongniart as hlanchardi have them armed only below 

 indicates that Kirby was correct in according the last generic distinct- 

 ness in his catalogue.^" But, as shown above, his use of Eumegalodon 

 in this connection was wrong, and thus a new generic name is needed 

 foi the reception of Megalodon hlanchardi Brongniart. For this pur- 

 pose the new generic name Ellatodon is here proposed. The relation- 

 ship of the genera and species above noted is as follows: 



Lesina Walker. (Type, Lesina lutescens Walker.) 



Megalodon Brull^ (not Sowerby). (Type, Megalodon ensifer Brull6.) 

 Eumegalodon Brongniart. (Type, Megalodon ensifer Brull^.) 



1. Lesina ensifer BruUe. 



2. Lesina lutescens Walker. 



Ellatodon Caudell. (Type, Megalodon hlanchardi Brongniart.) 

 Eumegalodon Kirby (not Brongniart). 

 1. Ellatodon hlanchardi Brogniart.

Subfamily Pseudophyllinae 



Genus CHLORACRIS Pictet and Saussure 



The genus Pseudophyllus was established by Serville ^^ with a single 

 included species, the Gryllus Tettigonia neriifolius of Stoll. Accord- 

 ing to present rules of nomenclature, specifically covered by paragraph 

 96 of the Entomological Code and opinion 65 of the International 

 Commission of Nomenclature, this species must be retained as the 

 genotype regardless of misdetermination. The disregard of this prin- 

 ciple has given rise to much confusion in this genus. The genus 

 Cleandrus of Stal ^^ was based on the single species Pseudophyllus 

 graniger Serville, a species now generally conceded to be a syno- 

 nym of neriifolius Stoll. Thus Cleandrus Stal is a synonym of 

 Pseudophyllus Serville, both genera having the same species as type.
