48 J. Wood-Mason — On a new Species of Phasmidse. [No. 1, 



membrane only, its apical half forming the deflesed and slightly incurved arms 

 of the forceps, which when closed are in contact at their tips only. Each 

 arm of the forceps is furnished on its upper edge with about five short and 

 stout dark brown incurved teeth, one of the teeth larger and more incurved 

 than the rest being placed at the very extremity ; and on the lower edge 

 at the base with a very strongly toothed nearly semicircular process, the 

 teeth of which interlock when the forceps is closed, and near the apex with 

 one or two teeth. The terminal ventral segment forms a conoidal mass, the 

 posterior slope of which is longitudinally carinate and the free end broadly 

 rounded. The cerci anales are short, obtuse, depressed, and just perceptibly 

 forcipated, being slightly but abruptly incurved at the very tips. 



¥ . Body entirely covered with granules, which are very much less 

 distinct on the seven posterior segments of the abdomen. Mesothorax con- 

 siderably dilated at the insertion of the legs. The abdomen tapers slightly 

 from base to apex of first segment, then widens slightly to the end of the 

 5th, which is marked above on its expanded posterior half with a low, rough, 

 wart-like excrescence ; the 7th is depressed and provided below at the middle 

 of its hinder margin with a very short broadly rounded process, from which 

 a limp acuminate process projects straight backwards ; three terminal dorsal 

 segments narrower, tapering slightly to their apex, the last scarcely emargi- 

 nate and carrying a longitudinally carinate semioval plate at its extremity ; 

 all the segments, especially the three last, with a small tubercle at the 

 middle of the hinder border of their dorsal arcs. Operculum sub-spatulate 

 in outline as seen from below, with a moderately well-developed carina 

 about the middle of its posterior half. The foliaceous crest of the fore- 

 tibise is expanded into a plaited lobe at the end of its proximal half. The 

 minute cerci are covered by the slightly produced postero-lateral angles of 

 the last segment. 



$ . Total length, 3 in. 7 lin. ; head, If ; proth., If ; mesoth., 11J ; 

 metath., 6f ; abd., 18 + 4i = 22i ; antenn., 27f lines. 



? . Total length, 4 in. 8f lin. ; head, 2i ; proth., 2f ; niesoth., 14f ; 

 metath., 9 ; abd,, 23i + 4f = 28 ; antenn., 23i lines. 



ELib. — Two males and a single female were captured on South Anda- 

 man by my native collector in 1872 ; and an immature example of the latter 

 sex was presented to me by Mr. E. H. Man, during my visit to these islands 

 in the same year. 



This species forms — with Lonchodes amaurops, Westw., nodosus, De- 

 Haan, Irevipes, Gr. E. Gray, uniformis, Westw., Craivangensis* DeHaan, 



* The whole structure of the two insects is opposed to the supposition that the 

 JPhasma nematodes is the male of the P. Crawangense of DeHaan : an insect with com- 

 paratively-short and filiform antennae, with the first joint of its fore tarsi long and 

 simple, and with minute conical cephalic horns, can hardly be the male of one in which the
