ASCHIPHASMIN.^. 



Genus Presbistus. 



Asc/iipasma, Brimner, Ann. Mus. Genova, xxxiii. p. 100 (1893). 



In lS3i ATestAvood founded a genus Aschlphusma, and in 1835 Gray founded a genus 

 Ferlamorphiis. The type of the former is A. annulipes, Westwood. ; and that of Gray, 

 PerlamorpJms Jiieroghjphlcus, Curt. MS. P. peleus, Gray, was added as a second species, 

 but has no chiim to be considered the type of Pe^^lamor pirns; and as P. hieroglyphicus. 

 Gray, is considered to be synonymous with Asclt/'phasma anniUipes, Westw., Gray's genus 

 and species both fall. But Brunner, who adoj)ts Westwood's later and incorrect spelling 

 Asclitpasma, divides the genus as follows: — 



1. Femora antica carinata et basi curvata Ascliijxisma, Westw. 



I'. Femora antica subteretia, basi non curvata Perlamorpha, Serv. 



As A. ani/nl/pes, Westw., the type of the genus, belongs to Pcrlamoiplia, Brunner, 

 which must, as we have seen, take the name of A.^chiphasma, it is necessary to rename 

 Asch/'pasma, Brunner, which I therefore designate Presbistus, and indicate Perlamorplius 

 peleus. Gray, as the type. 



P H A S M I N .E. 



Genus Abkachia. 



Ahrachla, Kiib. Ann. & Mag. Nat. Hist. (C) iii. p. 503 (1889). 



On re-examining my A. brevicornis, the type of this genus, I find that it possesses 

 triangular clefts at the ends of the tibire, which, coupled with the short antennae, will 

 bring it at least provisionally into this subfamily. The types are from Theresopolis, 

 Brazil. Bacteria longimana, Saussure, from Bahia, is certainly congeneric, and is 

 possibly the same species.
