97. Spirobolellus chrysoproctus sp. n. 



Celebes: Luwu. Two examples. 



Closely allied to Sp. chrysodirus, but differing as follows. 



The lateral portions of the collum are fuscous; there is a wide, 

 undivided median dorsal flavous band; the whole of the anal somite 

 flavous. The borders of the collum are less markedly sinuate, and the 

 anterior angle projects sligthly below the posterior. 



Number of somites 37 — 40. 



Length up to about 20 mm. 



98. Spirobolellus chrysogrammus sp. n. 



Celebes: Makassar. Several examples. 



Closely related to the preceding two but differing from both in colour. 



The whole of the collum fuscous except the middle of the dorsal 

 surface; the flavous dorsal band completely divided by a median black 

 band as in chrysodirus and the anal tergite is fuscous. 



Number of somite 36 — 38. 



Length, 17 mm.
