yellow bands ; the band on the 3rd segment is interrupted in the 
centre on the dorsal surface, and the anal segment is black with a few 
stiff black hairs studding the apex ; the macula on the anterior seg- 
ments and the bands on the others are indistinctly stained with red 
anteriorly. 
This species was first procured and given to me by Mr. A. Weston, 
Deputy Conservator of Forests, who informed me that he had found 
its nest also. As the nesting habits of all the Gembecide seem alike, 
and I myself found the species next described nesting, I have given all 
the information I am possessed of below. 
This species seems excessively rare; beyond the specimen kindly 
given me by Mr. Weston and one in his collection I have seen no 
others.
