The following twenty-six genera have not been found elsewhere: — 

 Ergaula, Catara, Prosoplecta, Areolaria, Lupparia, Pseudopbyllodromia, 

 Platyxyphus, Nisitra, Xabea, Condyloraera, Scepastus, Licola, Larnaca, 

 Lesina, Arachuacris, Piura^ •Sanabria, Leptoderes, Zacatula, Sexava, 

 Perena, Stenoxyphus, Opiptacris, Phloeoba, Tripetalocera and Ophioteltix. 

 Some of them have much singularity of structure. Xabea has a long 

 slender prothorax and very broad fore wings. Condylomera and Scepastus 

 have a great likeness to beetles ; Dr. Gerstacker, the author of the latter 

 genus, has mentioned its mimicry of a Pachyrhynchus. Ophiotettix differs 

 in an extraordinary way from the rest of the Tettigidae ; the head and the 

 antennae are very long and the latter are clubbed. 



Diploptera, Hexacentrus and Tegra inhabit Australia. Homalopteryx 

 inhabits South America towards the Atlantic. Nyctibora inhabits South 

 America towards the Atlantic and Central America. Agroecia, inhabits 

 Australia, Polynesia and South America towards the Atlantic. Lucina? 

 palliceps and Meroncidius? crenifolius, the one from Cambodia, the other 

 from Borneo, probably belong to different genera.

 Torbia, Veria, Tympanophora, Prochilus, Phasmodes, Moraba, Coryphites, 

 Petasida and Umisa are peculiar to Australia. Cylindrodes has a very 

 singular and larva-like appearance, and looks as if its metamorphose has 

 been arrested, or as if it is a remnant of an earlier race. Prochilus and 

 Phasmodes are widely different from all the other genera, and resemble the 

 Phasmidae. Hemideina inhabits New Zealand, the species are totally 

 destitute of wings, and some of them dwell in caves. Tropinotus inhabits 

 both sides of South America. Hyalopleryx is not an Australian genus ; 

 the species described as H. australis may be considered as forming a 

 section of Stenobothrus.
