joining the tarsi, which are also brown. Tlie femora of the fore- 

 legs are smooth, those of the middle and hindlegs witli two rows 

 below, the two preceding the last mucli larger, and connected by 

 a thin high ridge. The tibiie of the fore and middle legs have 

 two inferior rows, the hindlegs superior, about fourteen in each, 

 and nearly of the same size. All the spines correspond in colour 

 with the part adjoining. 



The male nymph is similarly marked, but the darker brown 

 preponderates, while the dull green is replaced by yellowish tints. 

 The imperfect wings are rather long, promiscuously directed ob- 

 li(|uely upwards, and closely applied to each other over the back. 

 The crest is nearly as well developed as in the adult. Leng-th of 

 body, one inch ; span of wings, four and a half to live inches. 



This genus will have to be placed near to PJnjUoptera and 

 riianeroptera, with which it agrees in general habitus, but it has 

 also through the dorsal appendages some affinity with Ileterodes 

 and Megapoda — in fact, it removes one of the distinctions between 

 the Locustidje and Acrididfe, viz., the absence of crests in the 

 former and presence in tlie latter. However, the form of the 

 antenna?, palpi, tarsi, cl'C, place it unquestionably among the 

 former. 



The first intimation of this very interesting insect was received 

 through Mr. J. M. Bagot, who forwarded a nearly mature male 

 nymph to the Museum, obtained in December, 1885, about 

 Terowie. The next, an adult male, was captured by Mr. F. H. 

 Ponton, near Beltana, during the early part of last May. The 

 tinder informed me that he captured it in his room one evening, 

 where it, no doubt, was attracted by the light. These are the 

 only specimens known. The female will most likely be little dif- 

 ferent in general aspect, but furnished with a long ovipositor. 

 The habitual food plant will probably be some of the Melaleuca 

 species or else the ISTative Pine.
