436 Mr. W. F. Khhy— Notes on PhasmidtB 



Genus Trtgonophasma, nov. 



Size ratlier large; head smooth, rounded and convex 

 behind the eyes ; tegraina raised and flattened Laterally, thus 

 forming a triangular hollow cone; wings much longer tiiaii 

 broad ; front femora curved at the base ; mesonotutn rarely 

 more than three times as long as the pronotum. 



Allied to Mormessoides, Brunner. 



TypCj Necroscia ruhescenSj Sauss. 



Genus Orthonecroscia, Kirb,, n. n. 



\\Necroscia, Brumier, Ann. Mus. Genova, xxxiii. p. 84 (1893), uec. Serv. 



None of the species described by Serville under Necroscia 

 appear to belong to the genus as restricted by Brunner to 

 species with the front femora not curved at the base. Neither 

 Stal nor Brunner happen to assign any type to Necroscia, 

 and I therefore rename Brunner's genus, specifying N. jilum^ 

 Westw., as the type of OrtJioneuria, and one of Servillc's 

 most conspicuous species, ^V. roseipennis, as the type of 

 Necroscia. 



Orthonecroscia puJcherrima, sp. n. 



Long. corp. 90, exp. al. 116 mm. 



Female. — Head green, somewhat convex above, with a 

 medial sulcation, on each side of which are three others, con- 

 verging behind. A square black spot between the antennas 

 and a large oval spot behind on each side. Antennas very 

 long and slender, green at the base and afterwards black, with, 

 several white bands. Pronotum with crossing sulci before 

 the middle ; before this green, behind black. Mesonotum 

 yellowish and slightly granulated above and green below. 

 Abdomen greenish (colour changed?), seventli and eighth 

 segments yellow, with a black spot at the extremity ; ninth, 

 tenth, and anal appendages almost entirely black ; operculum 

 green, as long as the abdomen. Legs green, banded with 

 dark brown or blackish. Tegmina strongly carinated and 

 thickly spotted with golden yellow or, near the margin, with 

 green. Costal area subhyaline, thickly covered with partly 

 connected golden-yellow spots, between which are four longi- 

 tudinal series of blackish spots ; costa bright green. The 

 membranous part of the wing brownish hyaline, and very 

 strongly iridescent. 



JIab. Borneo. 



Closely allied to O.filum^ Westw., but much larger and 

 more variegated in colour.
