Genus PARAPACHYMORPHA Brunner. 



1S93. Parajpachymorjpha Brunner, Ann. Mus. Civ. Stor. Nat. Geneva, 

 XXXIII, p. 95. 



Included P. nigra and spinosa Brunner. 



NEOHIRASEA »> n. subgen. 



Allied to Parapachymorpha s.s., but differing in the greater size of 

 the second antennal joint, the unarmed limbs, the transverse first 

 abdominal segment, the emarginate ninth dorsal segment, as well as 

 the accentuated character of the major body spines and the compara- 

 tive suppression of the minor ones. 



Type. — Phasma (Acanthoderus) japonicum Haan. 



Parapachymorpha (Neohirasea) japonica (Haan). 



1842. Phasma {Acanthoderus) japonicum Haan, Verhandel. Natuurlijke 

 Geschied., Orth., p. 135, tab. 12, fig. 4. [Japan.] 



Three females; Kyoto, Japan. (Y. Hirase, No. 48.) [A. N. S. 

 Phila.] 



Nikko, Japan. [U. S. N. M.] 



The Nikko specimen, while badly broken, represents an individual 

 considerably bulkier than either of the Kyoto specimens.

 PI. XLIV, figs. 3 and 8. [Batchian and Ternate.] 



Thirteen specimens; eight males, five females; Island of Obi, 

 Moluccas. [Coll. of Morgan Hebard.] 



In this fine series of specimens two individuals, one a male and the 

 other a female, are decidedly more spinosc than the remainder of the 

 series. This is almost wholly due to the development of the low 

 tuberculous excrescences of the other specimens into distinct spines, 

 and may be considered a purely individual feature. Considerable 

 discrepancy exists in the length of the anterior limbs, two undoubtedly 



^° Dedicated to Mr. Y. Hirase, of Kyoto, Japan, who has devoted a great amount 

 of time and labor to collecting representatives of the Mollusca and Orthoptera 

 of his native land. 



^' As Kirby has already noticed (Proc. Royal Dublin Soc, n. s., VI, p. 573\ 

 Acrophylla and Diura are directly synonymous. The former name was proposed 

 to replace the latter, which is preoccupied. Accordingly the use of the names as 

 distinct genera is a gross error.
