216 J. Wood-Mason — On new or little-known species of Phasmidse. [No. 3, 



being similarly armed with two minute spiniform tubercles. Meso- and me- 

 tathorax dilated at the insertion of the legs. Abdomen exactly half the 

 length of the body ; terminal dorsal segment strongly carinate, its posterior 

 and inferior angles produced into slender deflexed processes in contact at 

 their tips- only, which, like the sides of the resultant hiatus, are beset with 

 minute spinules ; terminal ventral segment pointed, carinate below for its 

 posterior two-thirds. Legs simple except for the presence of minute repre- 

 sentatives of the triangular spines seen near the apex of the femora in the 

 opposite sex ; their relative length 1, 3, 2.

Hab. The above description is taken from a specimen preserved in 

 alcohol captured on South Andaman by Mr. A. de Roepstorff. 



LOKCHODES AUSTENI, n. sp. 



8 . In size, thickness, and armature like the Acanthoderus Wallacei 

 of Westwood, but without the lateral spines and with a longer head and 

 more prominent eyes ; antennas long and setaceous ; head, pro- meso- and 

 metanotum with a few minute granules, especially on the edges of the two 

 last named ; meso- and metathorax carinate above and below ; the me30- 

 notum, both divisions of the metanotum, and the abdominal segments armed 

 with an erect spine at their extreme hinder ends, the abdominal spines 

 gradually decreasing in size backwards so as to become almost imperceptible 

 tubercles on the two penultimate segments ; terminal ventral and dorsal 

 abdominal segments much as in L. luteoviridis. Intermediate and posterior 

 femora with two minute spines near the apex below ; relative length of the 

 legs 1, 3, 2, the posterior being very little shorter than the anterior pair. 



Female unknown.

Hab. — Dikrang Valley, Assam ; collected during the Dafla Expedition, 

 by Major H. H. Godwin-Austen, after whom I have much pleasure in 

 naming it. 



Phibalosoma Westwoodii, n. sp. 



5 Very closely allied to P. Cantori, from which it differs in the great 



development of the lateral lobes of the 6th dorsal abdominal segment, and 



in the form of the head, the occipital region of which is broad, high, and 



convex, and surmounted by two rounded tubercles of very unequal size
