Genus ORXINES Stil. 

 1875. Orxines Stal, Recensio Orthopterorum, III, pp. 43 and 87. 

 Included Phasma (Lopaphus) macMottii Haan, Anophelepis xiphias 

 Westwood, and Necroscia zeuxis Westwood ; of which xiphias may be 

 selected as the tj^pe, as Westwood has given good figures of both sexes. 



Orxines xiphias (Westwood). 



1859. Anophelepis Xiphias Westwood, Cat. Orth. Ins. Brit. Mus., I, p. 71, 

 PI. IV, fig. 4 (cJ*) and fig. 5 ($). [Amboina.] 



Foiu' specimens; one male, three females; Island of Obi, Moluccas. 

 [Coll. of Mr. Morgan Hebard and Acad. Nat. Sci. Phila.] 



These specimens differ slightly from Westwood's figures, the meso- 

 notum and metanotum (without the median segment) being slightly 

 longer, but the discrepancies are so slight it would be very difficult to 

 satisfactorily differentiate them from the Amboina form. 



Subfamily NECROSCIN^. 



Genus SOSIBIA Stai. 



1875. Sosibia Stal, Recensio Orthopterorum, III, pp. 42 and 87. 



Type. — S. nigrispina Stal. 



Sosibia nigrispina StM. 



1875. S[osihia\ nigrispina Stal, Recensio Orthopterorum, III, p. 87. 

 [Malacca.] 



One female; Trong, Lower Siam. (Dr. W. L. Abbott.) [U. S, 

 N. M.] 



This specimen, which otherwise agrees very well with Stal's descrip- 

 tion, has the cephalic spines with more greenish than blackish colora- 

 tion. The median tibia? are exceptionally short, but Stal makes no 

 mention of this rather striking condition. 



Genus CALVISIA StM. 

 1875. Calvisia Stal, Recensio Orthopterorum, III, pp. 42 and 87. 

 Included Necroscia sangariiis, medora, virhius and hcmus Westwood, 

 of wliich the first can be selected as the type. 



Calvisia viridilineata (Bates). 



1866. Necroscia viridilineata Bates, Trans. Linn. Soc. London, XXV, p. 352. 

 [Ceram.] 



One female; Island of Obi, Moluccas. [Coll. of ^Morgan Hebard.] 



This agrees perfectly with Bates' description, except that the general 



tint of the limbs is more brownish than greenish, but this of course may 



be due to drying. SthVs 'maculiceps and thishe from the PhilipiDines^* 



appear to be closely related to this species.
