Two males of this species were taken at the foot of Gunong 

 Inas. The larger specimen had its abdomen 64 mm. long, its 

 hind wings each 62 mm. The upper pair of abdominal appendages 

 measure 6'5 mm. This is a veiy handsome creature, the rich 

 green and black thorax contrasting with the black yellow-ringed 

 abdomen. Previously recorded from Java and Amboyna.

I caught a female of this splendid species at Kwala Aring, in 

 thick forest. It agrees very closely with the type specimen 

 figured by Waterhouse, from Borneo (Proc. Ent. Soc. Lond, 1877, 

 p. X ; Trans. Ent. Soc. Lond. 1878, p. 119, fig. 4), but is somewhat 

 smaller. The length of the hind wing is 69 mm., breadth 22 mm. ; 

 length of abdomen 56 mm.; breadth of head 15 mm. Recorded 

 from Borneo and Sumatra. 



My specimen has a small supernumerary spine on the right side 

 in addition to the four normal spines on the end of the abdomen.

A single male and two females from Kwala Aring. Two other 

 females probably belong to another species, but I have not been 

 able to compare them with a series. They are from the same 

 locality as the rest.
