ON THE GENUS HYMENOTES. 493 



especially as Felton describes his insect as having an addi- 

 tional narrow membrane on the upper side of the hind thighs, 

 without noticing that it is notched, or representing any such 

 character. The antennae of the Banksian specimen are very 

 slender, and although there are only nine joints remaining, 

 they extend considerably beyond the front of the thoracic 

 shield, the two basal joints being very short and thickened. 



Having discovered amongst the insects collected at Manil- 

 la by Mr. Cuming, an insect closely allied to the preceding, 

 I communicated a description of the two species to the Zoo- 

 logical Society, on the 14th November, 1837, and which was 

 published in the Proceedings of the Society of that date. — 

 The following are the characters of the genus which I pro- 

 posed for their reception. 



" Hyme notes. Genus novum e familia Locustidarum, Tetrici affine. — 

 Corpus valcle compressum. Caput mediocre obliquum. Antenna breves 

 gracillimae filiformes, articulo lmo crasso, rotundato, 2ndo multo minori, 

 reliquis longitudine sensim crescentibus. Prothorax maximus, foliaceus val- 

 de compressus, folium aridum exacte referens, supra et ante caput angulariter 

 porrectus, valde elevatus et postice supra abdomen protensus ; parte posti- 

 ca subtus, pro receptione alarum et abdominis, canaliculata, prosternum in 

 collare pro receptione oris formatum. Pedes inter se basi longe distantes, 

 femoribus praesertim posticis foliaceis, tarsis posticis 3-articulatis," articulo 

 lmo subtus sub-biarticulato, articulo 2ndo minutissimo ; quatuor anticis 

 sub-biarticulatis, articulo lmo subtus sub-biarticulato. Ungues longi sub- 

 tus dente minuto armati. Pulvilli nulli.

Subsequently M. Serville, unacquainted with my memoir 

 above referred to, published the description of another spe- 

 cies of the same genus, for which he proposed the admirable 

 (but synonymical) name of Choriphyllum (dancing leaf) in 

 his volume upon the Orthoptera in the ' Suites a BufFon.' — 

 The following are its specific characters.
