37G Notes on Phasmidae in the British Museum. 



nearly equul length, the latter extending nearly to the extre- 

 mity of the fifth segment of the abdomen ; middle legs 

 shorter than the others. Face varied with whitish, and base 

 of the antennas shading from green into blue. Pronotum 

 with a transverse sulcus just before the middle; mesonotum 

 with four or five large asymmetrical black spines, thickened 

 at the base, and with a row of concolorous denticulations on 

 the sides, followed by a black spine before the base of the 

 four hinder legs ; hind femora slightly denticulated beneath 

 at the extremity ; median segment about two fifths of the 

 length of the metanotum, rounded in front; segments 2-6 of 

 the abdomen with a small terminal tooth on the median line ; 

 all the segments of the abdomen longer than broad, except 

 the tenth, which is carinated, but scarcely indented at the tip ; 

 operculum boat-shaped, scarcely longer than the ninth 

 segment ; cerci short, stout, slightly incurved. 



Female (long. corp. 110 mm.). — Bright green; rather 

 stout, but tapering towards both the head and tail ; a brownish 

 line running along the lateral borders of the thorax and 

 abdomen ; mesonotum with some small scattered black 

 tubercles, or, rather, granules ; meso- and metapleurse spinose 

 on the dark lateral line already referred to ; abdomen with 

 some more or less complete double carinations on the median 

 line of the hinder segment, and with a single slightly undu- 

 lating carina on each side ; there is a small tubercle or spine 

 at the end of the first seven segments, including the median 

 segment ; on segments 2-7 stand two or three green tubercles 

 above the lateral line ; the tenth segment is twice suddenly 

 contracted at the sides and terminates in an obtuse triangle 

 above; the double median carina on the ninth coalesces into 

 a single steep carina, which continues to the extremity of the 

 tenth ; operculum pointed and channelled, extending beyond 

 the tenth segment to more than twice the length of the latter. 



Rob. Tonkin (Matton Mountains, 2000-3000 metres), 

 April and May {Fruhstorfer). 



The male of this species is closely allied to P. Wallacei, 

 Westw., from Aru, the type of the genus, but is easily distin- 

 guished by the spineless head and the black spines on the 

 mesonotum. The female, however, like that of the following 

 species, wants the long, projecting, spear-like process above 

 the operculum, so conspicuous in that of P. Wallacei. The 

 specimens were received under the MS. name of Apora Iceta, 

 Brunn. The specific name I have of course retained, but 

 the generic name is preoccupied in Polyzoa, and is therefore 

 inadmissible.
