and legs bottle green ; underneath pale olive green. Length 

 (excluding- antennae and bind feet) 85 mm. (3.33 inches.) 



I also got specimens of Rhysida from Blakan Mati, Singapore, 

 and from Chantaboon, that apparently do not fall into any of 

 the above species. 



Order Geoph Hot no rph a . 



Family Geophilidce. 



12. Orphncrus brevilabiatus (Newport). The Luminous Centipede. 

 Malay Klamayer. 



I have caught this long, thin red centipede at Tahkamen, 

 Siam. in March 1897, in Government House. Singapore. October 

 1897, and in Bakar Bata House, Kedah, in May 1898 ; always 

 in roofs or upper stories of houses. On more than one occasion, 

 I have seen them at night on my mosquito curtains. Each 

 time I tested their luminosity ; when disturbed they give out a 

 bright but lurid green " phosphorescent " light, and as the 

 centipede moves it leaves a trail of light behind it on the surface 

 it is crawling over : this trail glimmers for a moment or so. and 

 then goes out. 



Besides Siam and the Malay Peninsula this species occurs 

 in other parts of the Oriental Region (Mergui Archipelago, 

 Java, Celebes. Flores. etc.) and also in tropical America. 



Family Dicellopkilidop. 



13. Mecistocephalus punctifrons, Newport. 



Of this long, thin centipede I got four specimens in the 

 earth at Chantaboon in January 1898 (no luminosity observed), 

 and also found a single individual under a piece of wood on the 

 top of Western Hill. Penan g, elevation 2725 feet. This latter 

 measured : — 

 length (excluding antenna? and hind legs) 52 mm. 

 ,. (including ,, ,, ., ,, ) 63 mm.

 Sumatra, Java, Flores and Mauritius.
